摘要
以枣渣为原料,探讨酶法制备膳食纤维工艺。结果表明:纤维素酶添加量为0.7%,35℃,水解时间120min,水溶性膳食纤维得率提高28%,不溶性膳食纤维持水性和溶胀性分别为886%和18.7ml/g。面粉中添加7%纤维可提高饼干的稳定性和起酥性,提高了饼干的品质。
The optimal process conditions of dietary fiber extraction from jujube （Ziziphusjujube MILL） fruit residue were studied with enzymatic method. This research utilized cellulase with substrate concentration 0.7%, temperature 35℃, and time 12 minutes. The yield of soluble dietary fiber increased 28%, the water-binding capacity of insoluble dietary fiber was 886%, and the dilatability was 18.7ml/g. Adding 7% jujube dietary fiber, the character of dough was improved in a certain sense. The quality of this kind of biscuit is fine and it is beneficial to health.
