机械预处理对酶解啤酒糟提取阿魏酰低聚糖的影响
Effect of mechanical pretreatment on extraction of feruloyl oligosaccharides from brewer's spent grain by enzymatic hydrolysis
摘要
Abstract
Mechanical pretreatment of brewer's spent grain (BSG) can change its tightness and the particle size,thus affecting enzymatic hydrolysis efficiency.With the increase of degree of crushing,enzymatic efficiency increase.The yield of feruloyl oligosaccharides (FOs) from untreated BSG by xylanase and cellulase were 31.89％ and 33.41％,respectively.And after the synergy of xylanase and cellulase,the yield of FOs increased to 47.01％.The yield of FOs from mechanical treated BSG hydrolyzed by xylanase and cellulase were 39.49％ and 50.36％,respectively.And after the synergy of xylanase and cellulase,the yield of FOs increased to 64.00％.The results indicated that pretreatment could improve the' efficiency of enzymatic hydrolysis,and the presence of cellulase and β-glucanase was beneficial to the effect of xylanase,thus improved the extraction efficiency of FOs from BSG and initially realized the high-value utilization of BSG.关键词
