食品非热加工技术的应用研究
摘 要
食品非热加工技术作为一种新兴的食品加工方法，近年来在全球范围内受到广泛关注。其主要特点在于能够在不显著提高食品温度的前提下，有效杀灭微生物、延长保质期并保持食品的营养成分和感官特性。本研究旨在探讨多种非热加工技术在食品加工中的应用效果，包括高压处理、脉冲电场、超声波处理和辐照技术等。通过对不同类型食品（如水果、蔬菜、肉类和水产品）进行实验研究，结合理化指标和微生物检测，评估这些技术的加工效率及其对食品品质的影响。研究发现，高压处理技术在保持食品原有风味和营养成分方面表现尤为突出，而脉冲电场技术则在杀菌效果上具有显著优势。此外，超声波处理能够有效改善食品的质构特性，而辐照技术则适用于大规模生产中的微生物控制。

RESEARCH ON THE APPLICATION OF FOOD NON-THERMAL PROCESSING TECHNOLOGY
ABSTRACT
As an emerging food processing method, food non-thermal processing technology has attracted wide attention worldwide in recent years. Its main characteristic is that it can effectively kill microorganisms, extend the shelf life and maintain the nutritional composition and sensory characteristics of the food without significantly increasing the food temperature. This study aims to investigate the application effects of various non-thermal processing techniques in food processing, including high voltage processing, pulsed electric field, ultrasonic processing and irradiation technology. The processing efficiency of these technologies and their impact on food quality were evaluated through experimental studies of different types of food (e. g., fruits, vegetables, meat and aquatic products), combining physical and chemical indicators and microbial detection. The study found that the high pressure treatment technology is particularly outstanding in maintaining the original flavor and nutrients of the food, while the pulsed electric field technology has significant advantages in the bactericidal effect. In addition, ultrasonic treatment can effectively improve the texture characteristics of food, while irradiation technology is suitable for microbial control in large-scale production.
