Abstract:Production technique of burdock oligosaccharide lactobacillus drink were studied through single factor test, combined with sensory evaluation of raw material was determined: burdock oligosaccharide added quantity, skimmed milk powder added quantity, sucrose content and fermentation time, ripening time, stabilizer added quantity, through response surface optimization software to determine the optimum process parameters of lactobacillus beverage: Burdock oligosaccharide 0.82% , skim milk powder 2.57%, sucrose 6.68%, fermentation time 9h, storage time 20h, soybean polysaccharide content of 0.25%. Nutritional of burdock lactobacillus drink is about protein 0.84%, fat 0g, carbohydrates 21.10%, pH4.47, live bacteria 1.05^109 CFU/mL.
