摘 要: 以罗非鱼下脚料为原料,用蛋白酶水解制取水解蛋白,水解产物含有较重的腥味和苦味。因而以蛋白质损失率、苦味值和腥味值为考察指标,采用活性炭通过单因素和正交实验对水解产物的脱腥脱苦工艺条件进行了探讨。确定最佳脱腥脱苦工艺条件为活性炭用量0.3%(w/v)、温度50℃、时间30min,在此条件下水解产物蛋白质损失率为5.8%,苦味值为3,腥味值为3,基本达到了脱苦脱腥的目的,提高水解蛋白的品质。 The tilapia heels was used as raw material and powder activated charcoal technology of removal bitter and fishiness in hydrolyzed protein was studied by single factor and orthogonal experiment. The optimal conditions of powder activated charcoal is 0.3%(w/v), temperature is 50℃, extraction time is 30min. The loss ratio of hydrolyzed protein is 5.8% and the bitterness value is 3 and the fishiness value is 3 under the optimal conditions.
