工业虾废料是蛋白质、甲壳素和类胡萝卜素的良好来源。一般来说，这些废物被丢弃而不试图使用，从而造成环境污染。采用碱性蛋白酶和胰酶对工业虾下脚料中的蛋白质、甲壳素和虾青素进行酶处理，以回收虾下脚料中的蛋白质、甲壳素和虾青素。水解度（DH）从6%增加到12%导致26%到28%的蛋白质回收率。Alcalase比胰酶更有效，在12%的DH下，蛋白质的回收率从57.5%增加到64.6%，虾青素的回收率从4.7增加到5.7 mg虾青素/100 g干废物。使用Alcalase酶解来自Xiphopenaeus kroyeri虾的工业废物，允许以水解产物的形式回收65%的蛋白质，此外还提供了用于回收虾青素和几丁质的合适条件。
Industrial shrimp waste is a good source of protein, chitin, and carotenoids. In general, this waste is discarded with no attempt to use it, thus contributing to environmental pollution. This study was aimed at recovering the 3 main components of industrial shrimp waste, protein, chitin, and astaxanthin, using enzymatic treatment with Alcalase and pancreatin. An increase in the degree of hydrolysis (DH) from 6% to 12% resulted in 26% to 28% protein recovery. Alcalase was more efficient than pancreatin, increasing the recovery of protein from 57.5% to 64.6% and of astaxanthin from 4.7 to 5.7 mg astaxanthin/100 g of dry waste, at a DH of 12%. The enzymatic hydrolysis of the industrial waste from Xiphopenaeus kroyeri shrimp using Alcalase allowed for 65% protein recovery in the form of hydrolysates, in addition to providing suitable conditions for the recovery of astaxanthin and chitin.
