AI Technical Summary
Existing methods for producing xylooligosaccharides suffer from low yield, numerous byproducts, and poor reaction controllability. In particular, traditional pretreatment methods are insufficient to efficiently break down the structure of raw materials when camellia shells have a dense structure.
Citric acid-sodium citrate solution was used as the catalytic system to hydrolyze camellia oleifera shells at 150-190℃ for 20-60 minutes. Combined with activated carbon column chromatography and spray drying, the hydrolysis intensity and pH value were precisely controlled to inhibit the further degradation of xylooligosaccharides.
It significantly improves the yield of xylooligosaccharides, enhances raw material utilization and equipment corrosion resistance, reduces equipment investment and operation and maintenance costs, and meets the requirements of green chemistry and sustainable development.
