食品保质期研究概况分析

当今社会,食品的制造、加工、储藏、分销、销售和消费各个环节中,保质期的重要性都是不容置疑的。但是目前对于不同类别食品的保质期预测没有通用方法,因为产品的自身属性、不同加工储存条件等均会影响食品的安全品质。综述国内外食品保质期的相关标准和法规情况,总结了基于品质衰变原理的化学品质衰变动力学、微生物生长动力学、感观预测的保质期预测方法、模型及案例,并结合前期研究基础,分析梳理目前我国保质期预测模型存在的问题,以期为食品经营制造者评估、设计和验证食品保质期提供一定依据。

Profile analysis of food shelf-life research

In today''s society, the importance of shelf life is indisputable in all aspects of food industry including manufacture, processing, storage, distribution, sale and consumption. However, there is no general method to predict the shelf life of different kinds of food, because the products own properties, different processing and storage conditions will affect the safety and quality of food. This paper reviewed the relevant standards and regulations of food shelf-life in China and aboard, summarized the shelf-life prediction methods, models and examples based on the quality decay principle of dynamics of chemical quality, microbial growth kinetics and sensory prediction, and analyzed the existing problems of the prediction models in China based on the previous research. We hope this paper will provide certain basis for the evaluation, design and verification of food manufacturers'' shelf-life.
