Application and Prospect of Modern Food Preservation Technology

Abstract

In recent years, food preservation technology has rapidly advanced, playing a crucial role in reducing food waste and enhancing economic efficiency. Simultaneously, it has provided consumers with more choices in their daily lives and shopping experiences. Traditionally, prolonged storage would often result in a loss of nutrients and a decline in taste. However, with the advent of modern preservation methods, the nutritional value of preserved foods is better maintained, ensuring that consumers receive essential nutrients even after extended storage. Furthermore, the emphasis on safety and reliability in food preservation is vital for ensuring that consumers can trust the products they purchase. With advanced preservation techniques, the risk of foodborne illnesses and contamination is significantly reduced, providing consumers with peace of mind about the safety of the food they consume. This paper comprehensively analyzes various preservation methods, including ultrasound technology, pulse electric field, and irradiation as physical methods, hurdle technology as a biological method, and the glass transition and drying in modified atmosphere packaging. By summarizing the findings from multiple research projects, the study aims to provide a reference for researchers engaged in relevant fields, helping them understand the current status of these technologies and identify potential areas for further improvement.
