荞麦壳水不溶性膳食纤维提取工艺的优化
Optimization of extracting water insoluble dietary fiber from buckwheat shell
摘要
Abstract
[ Objective ]Using chemical extraction, optimal technological parameters for water insoluble dietary fiber were determined to provide references for rationally utilization of buckwheat shell resources. [Method ]Water insoluble dietary fiber was extracted from buckwheat shell by chemical extraction method. Effects of liquid-solid ratio, reaction time and temperature, and NaOH concentration on extraction rate of water insoluble dietary fiber were studied and the extraction technology was optimized using an orthogonal experiment. [ Result ]The sequence of affecting extraction rate was like this: NaOH concentration>reaction time and temperature>liquid-solid ratio. The optimal technological parameters for chemical extraction of water insoluble dietary fiber were as follows: liquid-solid ratio 1.0:15.5. reaction time of 60 min, reaction temperature 45℃, NaOH concentration 4%. [Conclusion ]Under above-mentioned optimal extraction conditions, the water insoluble dietary fiber extracted from buckwheat shell was toast tan with water-holding capacity of 300.25 g/g and expansibility of 5.57 mI7g , which could be used as food additives.关键词
