Research on the Process of Extracting Sunflower Disk Polysaccharides by Ultrasonic-assisted Enzymatic Method
摘要
Abstract
Sunflower is one of the major cash crops in China.At present,the main disposal methods for sunflower disk are incineration,composting,or direct discard,resulting in a significant waste of resources.Sunflower disk are rich in natural polysaccharides with notable biological activity and application value,therefore,the extraction and utilization of polysaccharides from sunflower disk can enable the resource recovery of this agricultural waste.In this study,single-factor tests combined with Box-Behnken response surface methodology were used to investigate the effects of cellulase concentration,ultrasonication time,liquid-to-solid ratio,and their interactions on polysaccharide extraction yield from sunflower disk.The results showed that the optimal extraction conditions were a cellulase concentration of 2.32％,an ultrasonication time of 51 min,and a liquid-to-solid ratio of 16.8∶1(mL/g),achieving a polysaccharide extraction yield of 8.78％.This work provides a new approach for the development and utilization of sunflower receptacle polysaccharides,facilitates their application in fields such as food and medicine,and consequently enhances the economic value of agricultural crops.关键词
