优化莲蓬膳食纤维的均质改性工艺,并考察改性对其理化和应用特性的影响.在单因素试验的基础上,以可溶性膳食纤维(SDF)生成量为指标,采用响应面法优化莲蓬不溶性膳食纤维(LIDF)的高速均质改性工艺,获得最佳工艺参数为:均质转速19000 r/min、均质时间8 min、料液比1:19.5 (m:v),处理后SDF含量增加5.44％.比较LIDF改性前后的理化特性发现:高速均质能显著增强膳食纤维的溶胀率和持水力(P＜0.05),但对持油力及吸附胆酸钠能力的影响不显著(P＞0.05).LIDF的添加仅显著影响挂面的硬度和凝聚力(P＜0.05),对酥性饼干的硬度和酥性均无显著影响(P＞0.05).LIDF经改性后,在挂面中添加量由3％增加至4％以及在饼...

Optimizing the modification process of lotus seedpod fiber and studying the effect of modification on its physicochemical and application properties. Based on the result of single-factor experiments and yield of soluble dietary fiber（SDF）, the modification process of lotus seedpod insoluble dietary fiber（LIDF） was optimized by response surface methodology. The optimized technological parameters were as follows： processing speed 19000 r/min, processing time 8 min, ratio of material to liquid 1：19.5（m：v）. Under such condition, SDF conten...
