Smith & Nephew Fellowships in Medicine Smith & Nephew Associated Companies Limited invite applications for awards of six Fellowships in medicine. in 1971 . [11], The genus Durio is placed by some taxonomists in the family Bombacaceae, or by others in a broadly defined Malvaceae that includes Bombacaceae, and by others in a smaller family of just seven genera Durionaceae. The flesh can be consumed at various stages of ripeness, and it is used to flavour a wide variety of savoury and sweet desserts in Southeast Asian cuisines. 2, because EPO contains triglycerides oil, which is insoluble in water (Güner et al. Even apart from the smell, durians are a scientific marvel. It also helps bind and eliminates cancer-causing chemicals from the gut. [3][4] Durio zibethinus is the only species available in the international market: other species are sold in their local regions. This study investigated the effects of temperature (20 and 30 °C) and pH (pH 3.1, 3.9) on kinetic changes of chemical constituents of the durian wine fermented with Saccharomyces cerevisiae. Results: The most abundant monosaccharide in the carbohydrate composition of durian seed gum were galactose (48.6-59.9%), glucose (37.1-45.1%), arabinose (0.58-3.41%), and xylose (0.3-3.21%). The genus Durio has a complex taxonomy that has seen the subtraction and addition of many species since it was created by Rumphius. [28] On 22 May 2012, two other cultivars from Thailand that also lack the usual odour, Long Laplae and Lin Laplae, were presented to the public by Yothin Samutkhiri, governor of Uttaradit Province from where these cultivars were developed locally, while he announced the dates for the annual durian fair of Laplae District, and the name given to each cultivar. Durian seeds starch is quite potentially being used as bioplastics due to starch contained in the starch extracted from durian seeds is quite high, that was 76.65%, with the ratio of amylase: amylopectin 22.34: 54.32. Health Benefits of Durian fruit. Dietary fibers, minerals, and trace metals were comparable. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) [49], Other comparisons have been made with the civet, sewage, stale vomit, skunk spray and used surgical swabs. [3][10] In My Tropic Isle, Australian author and naturalist Edmund James Banfield tells how, in the early 20th century, a friend in Singapore sent him a durian seed, which he planted and cared for on his tropical island off the north coast of Queensland. Composition of the Durian Peel Biomass Average relative chemical contents (dry matter) of the durian peel biomass analyzed in this study are shown in Table1. [3] Four hundred years ago, it was traded across present-day Myanmar, and was actively cultivated especially in Thailand and South Vietnam. Durian rind was collected from Phatthalung province, Thailand. 1 Faculty of Chemical Engineering, University Teknologi MARA , Cawangan Johor, Kampus Pasir Gudang, Johor, Malaysia, ... composition of durian shell which mainly consists of 15.45% lignin, 73.54% holocellulose, 60.45% - cellulose and 23.09% hemi-cellulose (Jun et al., 2010). Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale yellow to red, depending on the species. Although the durian is not native to Thailand, Thailand is ranked the world's number one exporter of durian, producing around 700,000 tonnes of durian per year, 400,000 tonnes of which are exported to mainland China and Hong Kong. Novelist Anthony Burgess writes that eating durian is "like eating sweet raspberry blancmange in the lavatory". [3][44][45], This strong odour can be detected half a mile away by animals, thus luring them. D. zibethinus is not grown in Brunei because consumers there prefer other species such as D. graveolens, D. kutejensis, and D. oxleyanus. It instructs the reader to boil the roots of Hibiscus rosa-sinensis with the roots of Durio zibethinus, Nephelium longan, Nephelium mutabile and Artocarpus integrifolia, and drink the decoction or use it as a poultice. durian fruit (Vangnai, 1995). [75][76] A saying in Indonesian, ketiban durian runtuh, which translates to "getting hit by a durian", is the equivalent of the English phrase "windfall gain". [3], The earliest known European reference to the durian is the record of Niccolò de' Conti, who travelled to Southeast Asia in the 15th century. It has been planted in the Americas but confined to botanical gardens. It can be seen that durian peels have rich hemi-cellulose content. Copyright © 2020 Elsevier B.V. or its licensors or contributors. There are 13 common Malaysian varieties having favourable qualities of colour, texture, odour, taste, high yield, and resistance against various diseases. The first thing we need to do is determine the molar masses of all the compounds in this reaction. Composition of the Durian Peel Biomass Average relative chemical contents (dry matter) of the durian peel biomass analyzed in this study are shown in Table1. Table 1 Chemical composition, ultimate and heating value of durian peel as raw material chemical component ultimate values Heating Value (wt% d.b) (wt % d.a.f) (MJ/kg) cellulose hemicellulose acid insoluble compound Wax ash C H O (diff.) know the basic and chemical composition of durian peel. [37] Malaysia and Indonesia follow, both producing about 265,000 tonnes each. A survey conducted by Patra (1991) shows that 72 per cent of the Thais preferre to consume durian fruit especially the Mon Thong variety, due to its sweet and creamy taste, with soft and fine flesh and mild smell. A common saying is that a durian has eyes, and can see where it is falling, because the fruit allegedly never falls during daylight hours when people may be hurt. Malaysia negotiated a deal with China to export the whole fruit frozen for the first time to China starting in 2019, previously only Thailand was permitted to export the whole fruit to China. [1][14][15], Durio is often included in Bombacaceae because of the presence of monothecate anthers, as opposed to the bithecate anthers common to the rest of the mallows (and angiosperms, in general). These species are commonly distributed in Brunei, and together with other species like D. testudinarius and D. dulcis constitute a genetically diverse crop source.[36]. Transcript [BLANK_AUDIO] Previously we learned how to determine mass percent composition. In 1981, J. R. Croft wrote in his Bombacaceae: In Handbooks of the Flora of Papua New Guinea that "a feeling of morbidity" often follows the consumption of alcohol too soon after eating durian. Durian trees are large, growing to 25–50 metres (80–165 feet) in height depending on the species. Pang, Taylor’s University, Chemical Engineering Department, School of Engineering, No.1 ... hemicellulose, wax, and oil covering the external surface of the fiber cell wall [8]. The flesh is thick, not solid, yellow coloured, and has a sweet taste. Yunwei Niu, Zhengmin Yao, Qing Xiao, Zuobing Xiao, Ning Ma, Jiancai Zhu. ^ The traveller Wallace cites is Linschott (Wallace's spelling for Jan Huyghen van Linschoten), whose name appears repeatedly in Internet searches on durian, with such citations themselves tracing back to Wallace. In Java, the seeds are sliced thin and cooked with sugar as a confection. However, in more recent circumscriptions of Durioneae, the tribe into which Durio and its sister taxa fall, fleshy arils and spiny fruits are derived within the clade. [10], In 2019, researchers from the Technical University of Munich identified ethanethiol and its derivatives as a reason for its fetid smell. [83] The traditional method to counteract this is to pour water into the empty shell of the fruit after the pulp has been consumed and drink it. Tropical Science, 8,6-10. Yuyun Lu, Marilyn Kai Wen Voon, Jian-Yong Chua, Dejian Huang, Pin-Rou Lee, Shao-Quan Liu, The effects of co- and sequential inoculation of Torulaspora delbrueckii and Pichia kluyveri on chemical compositions of durian wine, Applied Microbiology and Biotechnology, 10.1007/s00253-017-8527-7, 101, 21, (7853-7863), (2017). 3, develops the odour about three days after the fruit is picked, which enables an odourless transport yet satisfies consumers who prefer the pungent odour. Data of that type can be determined through an experimental technique called elemental analysis. The durian fruit is a good source of antioxidant vitamin-C (about 33% of RDA). [38] Chantaburi in Thailand holds the World Durian Festival in early May each year. Animals such as Sumatran elephants and tigers are known to consume durians. This might be also responsible for significant (p < 0.05) changes of the solubility of the durian seed gum as a function of different drying conditions. Durian seeds starch is quite potentially being used as bioplastics due to starch contained in the starch extracted from durian seeds is quite high, that was 76.65%, with the ratio of amylase: amylopectin 22.34: 54.32. Durian (Durio zibethinus) is an exotic tropical fruit grown in Malaysia and throughout the Southeast Asian region. It is neither acidic nor sweet nor juicy; yet it wants neither of these qualities, for it is in itself perfect. Vitamin C was determined using 2,6 dichlorophenolindophenol visual titration method and fibre content were measured History "[47] Despite having tried many foods that are arguably more eccentric, Andrew Zimmern, host of Bizarre Foods, was unable to finish a durian upon sampling it, due to his intolerance of its strong taste. [10] Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale-yellow to red, depending on the species. This paper present the physical behaviour, chemical structure and crystallinity of the fibres, as observed by environmental scanning electron microscope (ESEM), Fourier transform infrared (FTIR) and X-ray diffraction (XRD). 36. The average It can be seen that durian peel and fiber contains lignin and hemicelluloses which is the primary cause of the change in the characteristics of the natural fibers in papermaking. The fruit, bark, roots, and leaves are used to make medicine. In Sabah, red durian is fried with onions and chilli and served as a side dish. [11][12] Durio s.s. and Boschia have indistinguishable vegetative characteristics and many shared floral characteristics. [42], The durian is a seasonal fruit, unlike some other non-seasonal tropical fruits such as the papaya which are available throughout the year. [9], Durio sensu lato has 30 recognised species. In addition, chemical composition of durian fiber from dried durian peel revealed that durian fiber is composed of holocellose, hemicelluse and lignin. [32][33] The fruit is medium-sized with oval shape, brownish green skin having short thorns. [70], In 1949, the British botanist E. J. H. Corner published The Durian Theory, or the Origin of the Modern Tree. According to Larousse Gastronomique, the durian fruit is ready to eat when its husk begins to crack. While Wallace cautions that "the smell of the ripe fruit is certainly at first disagreeable", later descriptions by Westerners are more graphic in detail. Effect of manure and chemical fertilizer on vegetative growth of off-season durian production. The nectar and pollen of the durian flower that honeybees collect is an important honey source, but the characteristics of the honey are unknown. [72] In its native Southeast Asia, the durian is an everyday food and portrayed in the local media in accordance with the cultural perception it has in the region. 6. The mechanical and chemical composition of the two soil types found in the designated sites are given in Table 3. 2007). of the rind, together with the noun-building suffix -an. [19] The centre of ecological diversity for durians is the island of Borneo, where the fruits of the edible species of Durio including D. zibethinus, D. dulcis, D. graveolens, D. kutejensis, D. oxleyanus, and D. testudinarius are sold in local markets. Chemical Composition The durian flesh is rich in food nutrients and vitamins: 100 g of the Mon Thong Table 1 Chemical composition and solubility of durian peel Chemical composition in Fiber Dried Durian Peel Standard Ash content 5.5 TAPPI-T211-om-93 Alcohot-benzene solubility 13.4 TAPPI-T204-om-93 hot-water solubility 39.5 TAPPI-T207-om-93 1% NaOH solubility 54.5 TAPPI-T212-om-93 lignin (ash corected) 10.9 TAPPI-T222-om-98 alpha cellulose 31.6 TAPPI-T203-cm-88 beta-cellulose 6.8 TAPPI … [31] Another common variety is "Udang merah", or red shrimp, found in the states of Pahang and Johor. It can be smelled from yards away. Yuyun Lu, Marilyn Kai Wen Voon, Jian-Yong Chua, Dejian Huang, Pin-Rou Lee, Shao-Quan Liu, The effects of co- and sequential inoculation of Torulaspora delbrueckii and Pichia kluyveri on chemical compositions of durian wine, Applied Microbiology and Biotechnology, 10.1007/s00253-017-8527-7, 101, 21, (7853-7863), (2017). 1 Altmetric. D. zibethinus is the only species commercially cultivated on a large scale and available outside of its native region. For example, in Singapore the strong demand for high quality cultivars such as the D24 (Sultan), and Musang King (Mao Shan Wang) has resulted in typical retail prices of between S$8 to S$15 (US$5 to US$10) per kilogram of whole fruit in 2007. A discussion on the fruit of the durian (Durio zibethinus Murr).See also Absts. The durian seeds, which are the size of chestnuts, can be eaten whether they are boiled, roasted or fried in coconut oil, with a texture that is similar to taro or yam, but stickier. 132, 1536. I'm going to write the molar masses over here, all in one spot. [3] Unripe durians may be cooked as a vegetable, except in the Philippines, where all uses are sweet rather than savoury. When durian is minced with salt, onions and vinegar, it is called boder. Inside there are five things like elongated oranges, and resembling thick butter, with a combination of flavours. Applied Microbiology and Biotechnology 2017, 101 (21) , 7853-7863. The chemical compositions of durian flesh with a total sugar content of 15%–20% and saccharose of 17% are nutritious enough to support the growth of LAB (Ketsa & Daengkanit, 1998; Leisner et al., 2001). [56] The thorny, armoured covering of the fruit discourages smaller animals; larger animals are more likely to transport the seeds far from the parent tree.[57]. Yunwei Niu, Zhengmin Yao, Qing Xiao, Zuobing Xiao, Ning Ma, Jiancai Zhu. The Durian fruit is famous for being a botanical stink-monster. The 6 additional species included in Durio s.l. Es durian (durian ice cream) is a popular dessert in Indonesia, sold at street side stall in Indonesian cities, especially in Java. [50] Sugar content, primarily sucrose, has a range of 8-20% among different durian varieties. https://doi.org/10.1016/j.foodcont.2020.107189. Chemical treatment, such as with alkali and silane, can be applied to the fiber surface so that the hydrophilic hydroxyl bonds can be removed (Wang et al. Among all the cultivars in Thailand, five are currently in large-scale commercial cultivation: Chanee, Mon Thong, Kan Yao, Ruang, and Kradum. It was called "Durian Botak" ('Bald Durian'). [3] Among the varieties of D. zibethinus, Thai varieties are sweeter in flavour and less odorous than Malay ones. Cellulose starts to decompose at … [20], Durian flowers are large and feathery with copious nectar, and give off a heavy, sour, and buttery odour. [65] Translated from the Latin in which Poggio Bracciolini recorded de Conti's travels: "They [people of Sumatra] have a green fruit which they call durian, as big as a watermelon. Mon Thong is the most commercially sought after, for its thick, full-bodied creamy and mild sweet-tasting flesh with relatively moderate smell emitted and smaller seeds, while Chanee is the best in terms of its resistance to infection by Phytophthora palmivora. The expansion of the durian industry and the advancement in processing of durian products has significantly expanded due to international trade. Estimation of Antioxidant Phytochemicals in Four Different Varieties of Durian (Durio Zibethinus Murray) Fruit Muhammad Aqeel Ashraf 1; Mohd.Jamil Maah ; Ismail Yusoff2 1Department of chemistry, University of Malaya, 50603 Kuala Lumpur, Malaysia 2Department of Geology, University of Malaya, 50603 Kuala Lumpur, Malaysia chemaqeel@gmail.com [47] He cited one traveller from 1599:[b] "it is of such an excellent taste that it surpasses in flavour all other fruits of the world, according to those who have tasted it. Dozens of chemical compounds contribute to the durian's, um, unique aroma that makes it the stinkiest fruit. There is disagreement over whether this name, bestowed by Linnaeus, refers to civets being so fond of the durian that the fruit was used as bait to entrap them, or to the durian smelling like the civet. Empirical Formula 19:22. In vitro and in vivo studies of the health and nutritional properties of durian (Durio zibethinus Murr.) The fruitlets were removed, and the EFBs were analysed for the chemical composition. Learn more on EarthSky. How does it put off such a rich array of offensiveness? Durian rind cellulose was prepared using two steps process according to Tawakkal et al. The results of chemical analysis and solubility performed on durian peel following the TAPPI standards are shown in Table 1. In addition to the chemical composition, drying process had a considerable effect on the molecular structure of durian seed gum as reported previously . [9][50] Durians from different species or clones can have significantly different aromas; for example, red durian (D. dulcis) has a deep caramel flavour with a turpentine odour while red-fleshed durian (D. graveolens) emits a fragrance of roasted almonds. Prof. Dorian A. Canelas. It can be seen that durian peels have rich hemi-cellulose content. The Kadayawan Festival is an annual celebration featuring the durian in Davao City. This pulp is the edible part, and its consistence and flavour are indescribable. [29], Popular cultivars in Malaysia and Singapore (Singapore imports most of its durians from Malaysia, hence the varieties are similar although there may be slight variation in the names) include "D24", which is a popular variety known for its bittersweet taste; "XO", which has a pale colour, thick flesh with a tinge of alcoholic fermentation; "Chook Kiok" (Cantonese meaning: bamboo leg) which has a distinctive yellowish core in the inner stem; and "Musang King" ('musang' is the Malay word for palm civet) which is usually the priciest of all cultivars. Durian was introduced into Australia in the early 1960s and clonal material was first introduced in 1975. In Malay peninsula and Sumatra, Pangasius catfish can be either cooked as tempoyak ikan patin (fish in tempoyak curry) or as brengkes (pais) tempoyak, which is a steamed fermented durian paste in banana leaf container. Exploring the Nutritional Contents and Benefits of Durian (Durio zibethinus)Tan Mei Chian & Shyamala Asohan. [54][55] While some of these animals eat the fruit and dispose of the seed under the parent plant, others swallow the seed with the fruit, and then transport it some distance before excreting, with the seed being dispersed as a result. [10] The latter belief can be traced back at least to the 18th century when Rumphius stated that one should not drink alcohol after eating durians as it will cause indigestion and bad breath. Scientists examine what chemicals make the Asian fruit smell like “turpentine and onions, garnished with a gym sock” Off-season durian production Somporn Na Nakorn1* and Chaiporn Chalumpak 2 1, 2, Department of Plant Science, Faculty of Agriculture, Rajamangala University of Technology Srivijaya, Nakhon Si Thammarat, Thailand 80110 Somporn , N. N. and Chalumpak , C. (2015). Stanton, W.R. (1966): "The chemical composition of some tropical plants: VI. Durian is the fruit of several tree species belonging to the genus Durio.There are about 30 recognised Durio species, however, at least nine of which produce edible fruits. These features are typical of flowers pollinated by certain species of bats that eat nectar and pollen. [50], People in Southeast Asia with frequent exposures to durian are able to easily distinguish the sweet-like scent of its ketones and esters from rotten or putrescine odours which are from volatile amines and fatty acids. This work represents the first study on the biotransformation of chemical constituents of durian wine via simultaneous alcoholic fermentation (AF) and malolactic fermentation (MLF) with non-Saccharomyces yeast and lactic acid bacteria (LAB), namely, Torulaspora delbrueckii Biodiva and Oenococcus oeni PN4. In 100 grams, raw or fresh frozen durian provides 33% of the Daily Value (DV) of thiamine and moderate content of other B vitamins, vitamin C, and the dietary mineral manganese (15–24% DV, table). Applied Microbiology and Biotechnology 2017, 101 (21) , 7853-7863. Different durian varieties from Malaysia, Thailand and Indonesia vary in their carbohydrate content by 16-29%, fat content by 2-5%, protein content by 2-4%, dietary fibre content by 1-4%, and caloric value by 84-185 kcal per 100 grams. Keywords : Biochar, Durian shell, Minerals, Chemical composition DOI : 10.14456/jmmm.2014.2 Introduction Durian (Durio zibethinus) called the “king of fruits” is a members of the family Bombacaceae and genus Durio (Brown, 1997). The wide range of descriptions for the odour of durian may have a great deal to do with the variability of durian odour itself. Furthermore, the challenges and future perspectives regarding the potential uses of the fruit are proposed. The mechanical and chemical composition of the two soil types found in the designated sites are given in Table 3. Of this, Malaysia exported 35,000 tonnes in 1999. [43] The increasing popularity of the fruit also saw the price of the Malaysian variety Musang King rise considerably; durian farmers would see the prices they get increasing from two ringgit per kilogram to 60 ringgit per kilo by 2018, which made it a far more lucrative than palm oil or rubber, leading to an increase in durian plantation. [44] A saying in Indonesian, durian jatuh sarung naik, meaning "the durian falls and the sarong comes up", refers to this belief. Sambal Tempoyak is a Malay dish made from the fermented durian fruit, coconut milk, and a collection of spicy ingredients known as sambal. ... as producing a food of the most exquisite flavour it is unsurpassed.[46][a]. seeds are a waste from durian paste processing that could find applications in food or non-food industries. The durian is cultivated in tropical regions, and stops growing when mean daily temperatures drop below 22 Â°C (72 Â°F). The object of the Fellowships is to enable overseas graduates to pursue study or Mass Percent 9:58. Preparation of Durian Skin Nanofibre (DSNF) and Its Effect on the Properties of Polylactic Acid (PLA) Biocomposites ... CHEMICAL COMPOSITION, MORPHOLOGICAL, SIZE AND DIMENSION ANALYSIS The cellulose, hemicellulose and lignin constituents in DSF and DSNF are presented in Table 2. [10], A common local belief is that the durian is harmful when eaten with coffee[44] or alcoholic beverages. [28] Another hybrid, Chantaburi No. The fruit can grow as large as 30 centimetres (12 inches) long and 15 cm (6 in) in diameter, and it typically weighs 1 to 3 kilograms (2 to 7 pounds). Fourier Transform Infrared Spectroscopy (FTIR) The change in chemical compositions of untreated durian rind, holocellulose and cellulose were examined by FTIR (Perkin Elmer, Spectrum One FT-IR Spectrometer, USA) with the attenuated total reflectance (ATR) technique. The durian symbolised the subjective nature of ugliness and beauty in Hong Kong director Fruit Chan's 2000 film Durian Durian (榴槤飄飄, lau lin piu piu), and was a nickname for the reckless but lovable protagonist of the eponymous Singaporean TV comedy Durian King played by Adrian Pang. Durians are also a rich source of volatile compounds that can benefit human health and the food industries. In Vietnam, the cultivar, Musang King, is a common variety preferred by consumers. The most abundant monosaccharide in the carbohydrate composition of durian seed gum were galactose (48.6-59.9%), glucose (37.1-45.1%), arabinose (0.58-3.41%), and xylose (0.3-3.21%). Some people in southern Thailand prefer their durians relatively young when the clusters of fruit within the shell are still crisp in texture and mild in flavour. "[66] The Portuguese physician Garcia de Orta described durians in Colóquios dos simples e drogas da India published in 1563. Physico-chemical Analyses Proximate composition of fresh durian and the leather formulations were deter- mined according to AOAC (1984) methods: moisture (22.01 3), ash (22.027), protein (22.052) and fat (14.018). N GCV 39,45 25,65 14,38 7,4 5,2 43,92 6,01 49,07 1,0 14,68 d.a.f dry ash free basis, diff. The initial fresh fruit bunches ( FFBs) were chosen from palms of eight, twelve and eighteen years old ( 10 EFBs from each age group ). After this, the samples were removed from the distilled water, blotted with tissue paper to remove excess water on the sample surface, and then weighed. [77] Nevertheless, signs warning people not to linger under durian trees are found in Indonesia. Off-season durian production Somporn Na Nakorn1* and Chaiporn Chalumpak 2 1, 2, Department of Plant Science, Faculty of Agriculture, Rajamangala University of Technology Srivijaya, Nakhon Si Thammarat, Thailand 80110 Somporn , N.

Named in some regions as the "king of fruits",[5] the durian is distinctive for its large size, strong odour, and thorn-covered rind. In 1929, J. D. Gimlette wrote in his Malay Poisons and Charm Cures that the durian fruit must not be eaten with brandy. and mangosteen (Garcinia mangostana). The various preferences regarding ripeness among consumers make it hard to issue general statements about choosing a "good" durian. [3] The most complete description of the medicinal use of the durian as remedies for fevers is a Malay prescription, collected by Burkill and Haniff in 1930. This review focuses on the chemical composition, potential uses, health benefits, and emerging technologies for the quality evaluation of durian, with the goal of providing information for its exploitation. 6. Different durian varieties from Malaysia, Thailand and Indonesia vary in their carbohydrate content by 16-29%, fat content by 2-5%, protein content by 2-4%, dietary fibre content by 1-4%, and caloric value by 84-185 kcal per 100 grams. In 100 grams, raw or fresh frozen durian provides 33% of the Daily Value (DV) of thiamine and moderate content of other B vitamins, vitamin C, and … [41] China is the major importer, purchasing 65,000 tonnes in 1999, followed by Singapore with 40,000 tonnes and Taiwan with 5,000 tonnes. [68] In the 18th century, Johann Anton Weinmann considered the durian to belong to Castaneae as its fruit was similar to the horse chestnut. [10] Since the bases of the scales develop into spines as the fruit matures, sometimes spineless durians are produced artificially by scraping scales off immature fruits. 1.1. The predominant fatty acid of the lipid fraction from the durian seed gum were palmitic acid (C16:0), palmitoleic acid (C16:1), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic … A study using durian peel waste gave a good result, like high carbon composition but had a low surface area. The crucial difference between the two is that anther locules open by apical pores in Boschia and by longitudinal slits in Durio s.s.[13] These two genera form a clade that is sister to another genus in the tribe Durioneae, Cullenia. [10] Among the thirty known species of Durio, nine of them have been identified as producing edible fruits: D. zibethinus, D. dulcis, D. grandiflorus, D. graveolens, D. kutejensis, Durio lowianus, D. macrantha, D. oxleyanus and D. Wearing a hardhat is recommended when collecting the fruit. Lu Y(1), Voon MKW(1), Chua JY(1), Huang D(1)(2), Lee PR(3), Liu SQ(4)(5). In Malaysia and Singapore, most consumers prefer the fruit to be as ripe and pungent in aroma as possible and may even risk allowing the fruit to continue ripening after its husk has already cracked open. the chemical composition and molecular structure of the heteropolysaccharide-protein polymer from durian seed gum. "[47] He cites another writer: "To those not used to it, it seems at first to smell like rotten onions, but immediately after they have tasted it they prefer it to all other food. [5] Ikan brengkes tempoyak is fish cooked in a durian-based sauce, traditional in Sumatra. The effects of co- and sequential inoculation of Torulaspora delbrueckii and Pichia kluyveri on chemical compositions of durian wine. [19] The fruit of many species has never been collected or properly examined, however, so other species may have edible fruit. These three genera together form a clade that is characterised by highly modified (mono- and polythecate, as opposed to bithecate) anthers. It is the most popular seasonal fruit in South East Asian countries. Wallace described himself as being at first reluctant to try it because of the aroma, "but in Borneo I found a ripe fruit on the ground, and, eating it out of doors, I at once became a confirmed Durian eater". 2006). [10], Prices of durians are relatively high, compared with other fruits. [26] In Indonesia, Ir Sumeru Ashari, head of Durian Research Centre, Universitas Brawijaya reported spineless durian from Kasembon, Malang. Vitamin C contents of the leather were relatively high and ranged between 21.6-26.6 mg/lOO g. Water activity (Aw) of all formulations ranged between 0.57-0.62 and caloric content, 431 -473 Kcall 00 g.
