[78] Strong nylon or woven rope netting is often strung between durian trees in orchards, serving a threefold purpose: the nets aid in the collection of the mature fruits, deter ground-level scavengers, and prevent the durians from falling onto people. Over thirty clones of D. zibethinus and six other Durio species have been subsequently introduced into Australia. sensory, physical and chemical composition of lai and durian cultivar were also studied. Durian rind cellulose was prepared using two steps process according to Tawakkal et al. Each cultivar has a distinct taste and odour. Transcript [BLANK_AUDIO] Previously we learned how to determine mass percent composition. Durian has been recognized as an important fruit especially for the underlying nutritional attributes of the fruit. We’ll tell you the results of a chemical analysis. [68] In the 18th century, Johann Anton Weinmann considered the durian to belong to Castaneae as its fruit was similar to the horse chestnut. Even apart from the smell, durians are a scientific marvel. 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 Durian fruit is famous for being a botanical stink-monster. The flesh is thick, not solid, yellow coloured, and has a sweet taste. For parts 4 and 5 see Title 4073, Vol. The fruit, bark, roots, and leaves are used to make medicine. The persistence of its odour, which may linger for several days, led certain hotels and public transportation services in Southeast Asia to ban the fruit. These features are typical of flowers pollinated by certain species of bats that eat nectar and pollen. For example, some popular clones are Sultan (D24), Kop (D99 Thai: กบ â€“ "frog" Thai pronunciation: [kòp]), Chanee (D123, Thai: ชะนี â€“ "gibbon" Thai pronunciation: [tɕʰániː]), Berserah or Green Durian or Tuan Mek Hijau (D145 Thai: ทุเรียนเขียว â€“ Green Durian Thai pronunciation: [tʰúriːən kʰǐow]), Kan Yao (D158, Thai: ก้านยาว â€“ Long Stem Thai pronunciation: [kâːn jaːw]), Mon Thong (D159, Thai: หมอนทอง â€“ Golden Pillow Thai pronunciation: [mɔ̌ːn tʰɔːŋ]), Kradum Thong (Thai: กระดุมทอง â€“ Golden Button Thai pronunciation: [kràdum tʰɔːŋ]), and with no common name, D169. The nectar and pollen of the durian flower that honeybees collect is an important honey source, but the characteristics of the honey are unknown. [26] In Indonesia, Ir Sumeru Ashari, head of Durian Research Centre, Universitas Brawijaya reported spineless durian from Kasembon, Malang. [38] Chantaburi in Thailand holds the World Durian Festival in early May each year. https://doi.org/10.1016/j.foodcont.2020.107189. ^ 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. 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%). Smith & Nephew Fellowships in Medicine Smith & Nephew Associated Companies Limited invite applications for awards of six Fellowships in medicine. Durian is an evergreen, tropical tree found in southeast Asia. [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. 1 Altmetric. These two neuro-chemicals are required to manage our emotions. seeds are a waste from durian paste processing that could find applications in food or non-food industries. 36. The characteristic of durian seed starch has water content 12.73%, ash content 0,51%, starch content 76,65%, amylose content 22.34%, amylopectin content 54.32%, protein content 11.61%, and fat content 0.61%. It is native to Borneo and Sumatra.[3]. (2012). [10] The durian is somewhat similar in appearance to the jackfruit, an unrelated species. [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. In the species name, zibethinus refers to the Indian civet, Viverra zibetha. [7][8] The species name 'zibethinus' derives from the name of the civet (Viverra zibetha), known for its odour. Tempoyak can be eaten either cooked or uncooked, is normally eaten with rice, and can also be used for making curry. DOI: 10.1007/s00253-017-8527-7. DOI: 10.1007/s00253-017-8527-7. 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). Several medical investigations on the validity of this belief have been conducted with varying conclusions,[10] though a study by the University of Tsukuba finds the fruit's high sulphur content inhibits the activity of aldehyde dehydrogenase, causing a 70 percent reduction of the ability to clear toxins from the body. It also helps bind and eliminates cancer-causing chemicals from the gut. All the spectra were recorded in the transmittance mode with a resolution of 4 cm-1 in the range of 4000 to 500 cm-1. Now that we've got the balanced chemical reaction we can go ahead and perform the calculations with the numbers. Durian rind was collected from Phatthalung province, Thailand. The Kadayawan Festival is an annual celebration featuring the durian in Davao City. Exploring the Nutritional Contents and Benefits of Durian (Durio zibethinus)Tan Mei Chian & Shyamala Asohan. [3][44][45], This strong odour can be detected half a mile away by animals, thus luring them. How does it put off such a rich array of offensiveness? A typical durian tree can bear fruit after four or five years. [63], Young leaves and shoots of the durian are occasionally cooked as greens. The chemical composition of durian seeds starch is presented in Table 1. 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.) 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. in 1971 . Durian trees have one or two flowering and fruiting periods per year, although the timing varies depending on the species, cultivars, and localities. [80][81], In Malaysia, a decoction of the leaves and roots used to be prescribed as an antipyretic. Sometimes the ash of the burned rind is added to special cakes. Temperature significantly affected growth of S. cerevisiae EC-1118 regardless of pH with a higher temperature leading to a faster cell death. Despite its great local popularity, the raw fruit is forbidden from some establishments such as hotels, subways and airports, including public transportation in Southeast Asia. The initial fresh fruit bunches ( FFBs) were chosen from palms of eight, twelve and eighteen years old ( 10 EFBs from each age group ). "[66] The Portuguese physician Garcia de Orta described durians in Colóquios dos simples e drogas da India published in 1563. 36. The flowers are produced in three to thirty clusters together on large branches and directly on the trunk with each flower having a calyx (sepals) and five (rarely four or six) petals. His theory was that endozoochory (the enticement of animals to transport seeds in their stomach) arose before any other method of seed dispersal, and that primitive ancestors of Durio species were the earliest practitioners of that dispersal method, in particular red durian (D. dulcis) exemplifying the primitive fruit of flowering plants. were compared with snake fruit (Salacca edulis Reinw.) [51], The fruit's strong smell led to its ban from the subway in Singapore; it is not used in many hotels because of its pungency. The mechanical and chemical composition of the two soil types found in the designated sites are given in Table 3. It can be smelled from yards away. It can be seen that durian peels have rich hemi-cellulose content. So this research aimed at producing a high surface area of AC with combining chemical activation process using H3PO4 and physical activation using N2. 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. The durian is cultivated in tropical regions, and stops growing when mean daily temperatures drop below 22 Â°C (72 Â°F). First used around 1580, the name "durian" is derived from the Malay language word dûrî (meaning 'thorn'),[6] a reference to the numerous prickly thorns [62] Dried durian flesh can be made into kripik durian (durian chips). Vitamin C was determined using 2,6 dichlorophenolindophenol visual titration method and fibre content were measured Cellulose starts to decompose at … 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. [10], Prices of durians are relatively high, compared with other fruits. As mentioned in the The chemical composition of durian seeds starch is presented in Table 1. © 2020 Elsevier Ltd. All rights reserved. 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. Chemical Composition The durian flesh is rich in food nutrients and vitamins: 100 g of the Mon Thong know the basic and chemical composition of durian peel. 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. The seeds can also be eaten when cooked. It can be seen that it contains lignin and hemicellulose which is the primary cause of the change in the characteristics of the natural fibers in the composite. So this research aimed at producing a high surface area of AC with combining chemical activation process using H3PO4 and physical activation using N2. 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 … [50] Sugar content, primarily sucrose, has a range of 8-20% among different durian varieties. [21] According to research conducted in Malaysia in the 1970s, durians were pollinated almost exclusively by cave fruit bats (Eonycteris spelaea);[10] however, a 1996 study indicated two species, D. grandiflorus and D. oblongus, were pollinated by spiderhunters (Nectariniidae) and another species, D. kutejensis, was pollinated by giant honey bees and birds as well as bats. ] Chantaburi in Thailand ) anthers acid, and health Benefits of durian accompaniment.
