To produce xylo-oligosaccharides (XOS) from the agriculture waste, which included, green coconut and vegetable cocktail. The two pretreatment - hydrogen peroxide-acetic acid (HP-AC) and sodium hypochlorite-sodium hydroxide (SH-SH) - were used for this study. The optimal conditions for the pretreatment were 80 °C, 4.0 % NaClO, and 2 h, followed by 0.08 % NaOH, 55 °C, and 1 h. Further enzymatic hydrolysis of green coconut (GC) and vegetable cocktail (VC) were performed and found in case of GC, the best outcomes were observed. Different types of XOS were obtained from the treated biomass whereas a single type of XOS xylo-pentose was obtained in high quantity (96.44 % and 93.09 % from CG and VC respectively) with the production of other XOS < 2 %. This study presents a reasonably secure and economical method for turning secondary crop residue into XOS and fermentable sugars.

UI	MeSH Term	Description	Entries
D009844	Oligosaccharides	Carbohydrates consisting of between two (DISACCHARIDES) and ten MONOSACCHARIDES connected by either an alpha- or beta-glycosidic link. They are found throughout nature in both the free and bound form.	Oligosaccharide
D005965	Glucuronates	Derivatives of GLUCURONIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that include the 6-carboxy glucose structure.	Glucosiduronates,Glucuronic Acids,Acids, Glucuronic
D006868	Hydrolysis	The process of cleaving a chemical compound by the addition of a molecule of water.
D000073893	Sugars	Short chain carbohydrate molecules that have hydroxyl groups attached to each carbon atom unit with the exception of one carbon that has a doubly-bond aldehyde or ketone oxygen. Cyclical sugar molecules are formed when the aldehyde or ketone groups respectively form a hemiacetal or hemiketal bond with one of the hydroxyl carbons. The three dimensional structure of the sugar molecule occurs in a vast array of biological and synthetic classes of specialized compounds including AMINO SUGARS; CARBASUGARS; DEOXY SUGARS; SUGAR ACIDS; SUGAR ALCOHOLS; and SUGAR PHOSPHATES.
