Only a small part of the pineapple skin is used as feed, and the rest is treated as waste. It is a pity because these wastes in everyone’s eyes contain 35% hemicellulose, which is a valuable material for the production of xylooligosaccharides. Therefore, the Zhongzheng team invested in research and development, The process from pineapple peel to xylooligosaccharide only takes 2 to 3 days, and the yield of xylooligosaccharide is high, and it can also produce arabinose that can inhibit the absorption of sucrose at the same time, becoming a multifunctional prebiotic.
