高压切换冻结在食品保鲜中的应用

Mechanism and application progress of high-pressure-shift-freezing in food preservation

摘要: 高压切换冻结是一种新兴的食品保鲜技术,在冻结过程中利用高压与温度来控制冻结过程,改变冰晶体的大小、形态与分布,从而改善冻品的品质。文章详细阐述了高压切换冻结法的基本原理以及在食品保鲜领域研究的进展,最后分析了该技术存在的问题,以对高压切换冻结技术的进一步研究提供参考。

Abstract: High-pressure-shift-freezing (HPSF) , an emerging food preservation technique, takes advantages of different ice crystals properties such as size, shape and distribution resulting from controlling of high pressure and temperature to improve the quality of frozen food.The basic principle of HPSF as well as the study of technique in food industry was depicted.In addition, the main problems were listed, and it could be a reference for further research of HPSF in food preservation.
