“…It is widely used as fresh drink, fermented to produce alcoholic beverages such as toddy, wine, and arak, ethanol, and as a raw material for sugar (syrup, cake and powder) production (Hebbar et al, ; Naknaen & Meenune, ; Naknean, ). Meanwhile, sugarcane is known as important commercial crop and is recognized as a source of sugar, jaggery (a semi refined sugar mostly used in India and Pakistan), and ethanol (Nath, Dutta, Kumar, & Singh, ; Nguyen, Harifara, & Shiro, ). It is also used as a fodder for feeding livestock, and its by‐products are used in board making (Miller & Raczuk, ).…”

This study was carried out to compare the antioxidant and nutritional properties of coconut (Cocos nucifera L.) sap with other natural sources of sugar such as sugar palm (Borassus flabellifer) and sugarcane (Saccharum officinarum L.). Coconut sap and juice from sugar palm and sugarcane were analyzed for proximate composition, pH and total soluble solid (TSS), color, sugar profile, vitamin profile, antioxidant properties (total phenolic contents, DPPH, FRAP, and ABTS), and mineral content. The results indicated that coconut sap possesses high DPPH (23.42%), FRAP (2.09 mM/ml), and ABTS (21.85%) compared with the juices. Coconut sap also had high vitamin C (116.19 µg/ml) and ash (0.27%) contents, especially in potassium (960.87 mg/L) and sodium (183.21 mg/L) which also indicating high content of minerals. These properties showed that coconut sap could be served as a potential healthier sugar source compared with sugar palm and sugarcane juices.

“…According to residents in the Lamota area (Timor Island), Timor Lorikeets like to lick saps tapped on coconut trees (Duhan, 2017). However, this tapped sap should be consumed within a day, before it ferments spontaneously to alcohols and acids (Nguyen et al, 2016). Therefore it is also not practical as a food in captivity.…”

Trichoglossus haematodus (Linnaeus, 1771) is nectarivorous bird that feed on nectar as a source of carbohydrate. In captivity, it is not practical to provide a continued diet of nectar from the flowers. Therefore, this study aimed to find other carbohydrate sources such as brown sugar as substitute nectar for T. haematodus. Twelve wild T. haematodus in four cages offered five types different brown sugar solution with different concentrations. Since brown sugar has low protein content, therefore the birds also offered commercial baby biscuit to meet the protein requirement. The results showed that the birds like to consume all types of brown sugar solution with sugar concentration up to 40% . However, the siwalan brown sugar solution was the most favored by the bird. over the other type of brown sugar solutions (aren, coconut, sugar cane and regular commercial "palm" brown sugar). Furthermore, the result showed that the birds prefer commercial baby biscuit was soaked in the brown sugar solution with concentration 20%. This study provides the information that the brown sugar solution based diet has potency as an alternative carbohydrate source to substitute nectar for T. haematodus in captivity which is more practical and can increase the survival rate in birds.

“…Coconut palm is widespread throughout the Western Pacific and Asia, including India, and countries in Southeast Asia, for example, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam (Minh 2014;Nguyen et al 2016;Sudha et al 2019). Palmyra palm is widely distributed in tropical countries in Africa, South America, Australia, and South Asia, for example, India, Nepal, Sri Lanka, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam (Barh and Mazumdar 2008;Minh 2014;Nguyen et al 2016;Phaichamnan et al 2010;Sudha et al 2019). Nipa palm is commonly found in swamp areas favoring brackish water environments, such as estuaries.…”

“…This palm is regarded as an important component of Southeast Asian mangrove vegetation (Hossain and Islam 2015). Nipa palm grows naturally in various countries, for example, India, Sri Lanka, Bangladesh, Cambodia, Indonesia, Malaysia, Myanmar, the Philippines, Thailand, Vietnam, Australia, Papua New Guinea, the Solomon Islands, and Nigeria (Mehrotra et al 2003;Nguyen et al 2016;Tsuji et al 2011).…”

This study aimed to explore communities and the ethanol-fermenting ability of yeasts in fresh coconut, palmyra, and nipa palm saps. From the 90 samples of coconut, palmyra, and nipa palm saps, 204 yeast isolates were isolated and identified as 15 species in the phylum Ascomycota and a species (one strain) in Basidiomycota. Saccharomyces cerevisiae, Hanseniaspora guilliermondii, and Lachancea thermotolerans were found in the saps of all three palm species. Candida tropicalis and Pichia kudriavzevii were obtained from the coconut and palmyra palm saps, Hanseniaspora vineae, Lachancea fermentati, and Pichia manshurica were present in the coconut and nipa palm saps, whereas Torulaspora delbrueckii was found in the palmyra and nipa palm saps. The species with the highest occurrence in the saps of coconut, palmyra, and nipa palms was S. cerevisiae with 76.67%, 86.70%, and 100% frequency of occurrence, respectively. Using principal coordinates analysis for ordination, no marked difference was observed in the yeast communities from the saps of the three palm species. A total of 199 isolates were found to possess ethanol-fermentation ability when cultivated using shake flask in 160 g/L of glucose medium at 28°C for 48 h. Lachancea fermentati YSP-383, isolated from nipa palm sap, produced the highest amount of ethanol (76.74 g/L). Twenty-six isolates of Candida sanyaensis (1), C. tropicalis (1), H. guilliermondii (7), L. fermentati (8), L. thermotolerans (1), Pichia kudriavzevii (2), and S. cerevisiae (6) produced high amounts of ethanol ranging from 69.57 to Electronic supplementary material The online version of this article (
