中文摘要: 利用纤维素酶对油橄榄果渣糊进行酶解,以提高果渣糊的可溶性膳食纤维(soluble dietary fiber,SDF)含量。以SDF 含量和模糊数学感官评分为评价指标,采用单因素试验和响应面试验对酶解工艺进行优化,探讨纤维素酶添加量、酶解温度、酶解时间、酶解pH 值对油橄榄果渣糊的影响,并采用Box-Behnken 试验设计优化酶解工艺。结果表明,在纤维素酶添加量0.42%、酶解温度41 ℃、酶解时间30 min、酶解pH4.5 条件下,得到可溶性膳食纤维含量最多、模糊数学感官评分最高,分别为0.132 g 和88.5。
Abstract:Cellulase was used to hydrolyze olive residue to increase the soluble dietary fiber (SDF) in the residue. With the soluble dietary fiber(SDF) content and fuzzy mathematical sensory score of the meal replacement paste prepared from olive residue as evaluation indexes,single factor and response surface tests were carried out to optimize the enzymatic hydrolysis conditions including the cellulase addition amount,temperature,time,and pH of enzymatic hydrolysis by the Box-Behnken design. The results showed that the product obtained by enzymatic hydrolysis with 0.42% cellulase at 41 ℃ and pH4.5 for 30 min had the highest soluble dietary fiber content and fuzzy mathematical sensory score,which were 0.132 g and 88.5,respectively.
