This review summarizes the most common biological methods and their conditions for the recovery of bioactive compounds such as chitin/chitosan, proteins/peptides and carotenoids from marine crustacean processing side‐streams (MCPS). Chitin can be efficiently extracted from MCPS by adding proteases to hydrolyze the proteins (enzymatic hydrolysis), or by using (non‐)lactic acid fermentation to digest and eliminate nonchitinous compounds. Peptides with antimicrobial, antioxidant and antihypertensive activities can be generated via fermentation and enzymatic hydrolysis; in addition, carotenoid extraction can be enhanced by both techniques. This review also briefly demonstrates the advantages, challenges and future perspectives of applying biological methods for the valorization of MCPS. These biological methods may provide an alternative solution to minimize the environmental and economic impact of inefficient waste management. Moreover, MCPS can be used to produce high value‐added compounds with potent bioactivities. Ultimately, these compounds produced via optimized biological methods can be commercialized for different applications. © 2021 Society of Chemical Industry

将海洋甲壳类副产物生物转化为生物活性物质的评论

这篇综述总结了从海洋甲壳类动物加工支流（MCPS）中回收生物活性化合物（例如甲壳质/壳聚糖，蛋白质/肽和类胡萝卜素）的最常见生物学方法及其条件。通过添加蛋白酶来水解蛋白质（酶促水解）或使用（非）乳酸发酵来消化和消除非壳多糖化合物，可以从MCPS中有效地提取几丁质。具有抗微生物，抗氧化和降压活性的肽可以通过发酵和酶促水解产生。此外，两种技术均可增强类胡萝卜素的提取。这篇综述还简要说明了应用生物学方法对MCPS进行价值化的优势，挑战和未来前景。这些生物方法可以提供一种替代解决方案，以最大程度地减少无效废物管理对环境和经济的影响。此外，MCPS可用于生产具有有效生物活性的高附加值化合物。最终，通过优化的生物学方法生产的这些化合物可以商业化用于不同的应用。©2021化工协会
