Processed fish by-products are valuable sources of peptides due to their high protein content. However, the bitterness of these peptides can limit their use. This review outlines the most recent advancements and information regarding the reduction of bitterness in fish by-products derived peptides. The sources and factors influencing bitterness, the transduction mechanisms involved, and strategies for reducing bitterness are highlighted. Bitterness in peptides is mainly influenced by the source, preparation method, presence of hydrophobic amino acid groups, binding to bitter receptors, and amino acid sequence. The most widely utilized techniques for eliminating bitterness or enhancing taste include the Maillard reaction, encapsulation, seperating undesirable components, and bitter-blockers. Finally, a summary of the current challenges and future prospects in the domain of fish by-products derived peptides is given. Despite some limitations, such as residual bitterness and limited industrial application, there is a need for further research to reduce the bitterness of fish by-products derived peptides. To achieve this goal, future studies should focus on the technology of fish by-products derived peptide bitterness diminishment, with the aim of producing high-quality products that meet consumer expectations.
由于其高蛋白含量，加工后的鱼副产品是肽类物质的宝贵来源。然而，这些肽类物质的苦味会限制其应用。本综述概述了有关降低鱼副产品衍生肽苦味的最新进展和信息。强调了苦味的来源和影响因素、涉及的转导机制以及降低苦味的策略。肽中的苦味主要受来源、制备方法、疏水性氨基酸基团的存在、与苦味受体的结合以及氨基酸序列的影响。消除苦味或增强口感最广泛使用的技术包括美拉德反应、包埋、分离不良成分和苦味抑制剂。最后，总结了鱼副产品衍生肽领域目前的挑战和未来的前景。尽管存在一些限制，如残留苦味和有限的工业应用，但需要进一步研究以降低鱼副产品衍生肽的苦味。为了实现这一目标，未来的研究应集中在鱼副产品衍生肽苦味降低技术上，旨在生产出满足消费者期望的高质量产品。
