Xylooligosaccharide(XOs)-enriched Wheat bran beverage was prepared by main processing units including baking,enzymatic hydrolysis,clarification and seasoning.Baking conditions is 180℃,20min.Enzyme xylanase was used to hydrolyze xylan into XOs;Flavorzyme was used to hydrolyze protein into peptides and mid-temperature α-amylase were used to hydrolyze starch into glucose.Optimal conditions of combined enzyme hydrolysis were: xylanase 153 U/g wheat bran,flavorzyme 138U/g wheat bran,mid-temperature α-amylase 60U/g wheat bran,solid to liquid ratio 1:8,pH 6.0,reaction temperature 50℃ and reaction time 4h.Dilute hydrolyzed was clarified by adding 0.2 gLbentonite and 0.1 g/L chitosan for 30min.The reaction was then followed by seasoning with 10 g/L honey,60 g/L sucrose and 0.75 g/Lcitric acid,ultra high temperature sterilizing and aseptic filling.The beverage,containing abundant XOs and peptides,is a healthy drink.
