高压处理对海鲜产品中微生物及酶活性的影响
摘要
随着人们生活水平的提高和消费观念的转变，海鲜产品因其丰富的营养价值、独特的口感和风味，逐渐成为人们餐桌上的重要选择。然而，海鲜产品由于其高水分、高蛋白和易腐特性，在加工、储存和运输过程中极易受到微生物的污染，导致品质下降、保质期缩短，甚至引发食品安全问题。因此，如何有效抑制或杀灭海鲜产品中的微生物，同时保持其原有的营养价值和风味，成为海鲜加工行业亟待解决的关键问题。传统上，海鲜产品的保鲜方法主要包括冷藏、冷冻、腌制、熏制等，但这些方法往往存在保鲜效果有限、影响产品口感和营养成分等弊端。近年来，随着科学技术的进步，高压处理技术作为一种新型的非热加工方法，因其能够有效灭活微生物、保持食品原有品质而备受关注。高压处理通过利用高压环境对微生物细胞和酶系统产生物理性破坏，从而达到杀菌和抑制酶活的目的，且无需添加任何化学防腐剂，符合现代消费者对健康、安全、绿色食品的需求。因此，本研究旨在深入探究高压处理技术在海鲜产品加工中的应用，特别是在对微生物及酶活性的影响方面，以期为海鲜加工行业的可持续发展提供新的思路和技术支持。通过本研究，我们期望能够揭示高压处理技术的杀菌机制、酶活调控机制及其对海鲜产品品质的影响规律，为高压处理技术在海鲜保鲜中的广泛应用奠定理论基础。

Abstract
With the improvement of people's living standards and the change of consumption concepts, seafood products have gradually become an important choice for people's tables because of its rich nutritional value, unique taste and flavor. However, due to its high moisture, high protein and perishable characteristics, seafood products are highly susceptible to microbial contamination during processing, storage and transportation, resulting in reduced quality, shortened shelf life, and even food safety issues. Therefore, how to effectively inhibit or kill microorganisms in seafood products while maintaining their original nutritional value and flavor has become a key issue to be solved in seafood processing industry. Traditionally, the preservation methods of seafood products mainly include refrigeration, freezing, curing, smoking, etc., but these methods often have limited preservation effect, affecting product taste and nutritional composition and other drawbacks. In recent years, with the progress of science and technology, high-pressure processing technology, as a new non-thermal processing method, has attracted much attention because of its ability to effectively inactivate microorganisms and maintain the original quality of food. High pressure treatment through the use of high pressure environment to produce physical damage to microbial cells and enzyme systems, so as to achieve the purpose of sterilization and inhibition of enzyme activity, and without adding any chemical preservatives, in line with modern consumers for health, safety, green food needs. Therefore, this study aims to deeply explore the application of high-pressure treatment technology in seafood processing, especially in terms of its impact on microbial and enzyme activities, in order to provide new ideas and technical support for the sustainable development of seafood processing industry. Through this study, we hope to reveal the bactericidal mechanism and enzyme activity regulation mechanism of high-pressure treatment technology and its influence on the quality of seafood products, and lay a theoretical foundation for the wide application of high-pressure treatment technology in seafood preservation.
