摘要
目的:优化黑木耳多糖一次热水浸提工艺,提高黑木耳多糖得率。方法:以黑木耳多糖得率为指标,通过单因素试验和响应面试验考察木耳浸提前干燥温度、粉碎粒度、浸泡时间以及膨化处理的影响。结果:最佳工艺为干燥温度85℃、粉碎粒度100~160目、浸泡时间60 min、浸提温度100℃,此时黑木耳多糖得率为9.26%。结论:经优化得到的最佳浸提工艺是一种可行的生产黑木耳多糖的方法。
【Objective】Optimize the one-time hot water extraction process of Auricularia auricula polysaccharide to improve the yield of Auricularia auricula polysaccharide.【Method】Taking the yield of Auricularia auricula polysaccharide as the index,the effects of drying temperature,crushing particle size,soaking time and expansion treatment were investigated by single factor experiment and response surface methodology.【Result】The best technology of extracting Auricularia auricula polysaccharide by one-time hot water was drying temperature 85℃,crushing particle size 100—160 mesh,soaking time 60 minutes,extraction temperature 100℃.Under this condition,the yield of polysaccharide was 9.26%.【Conclusion】The optimized extraction process is a feasible method to produce Auricularia auricula polysaccharide.
