食品冷链的技术发展

Technological Development of Food Cold Chain

目的综述食品冷链的技术发展现状,为促进食品冷链发展提供参考依据。方法对近年来国内外食品冷链技术的应用和研究现状进行分析,介绍食品冷链中各个环节(预冷、速冻、冷库、冷藏运输及冷藏销售等)的技术进展。结果我国食品冷链各个环节的技术及应用还存在一些问题,还有较大的发展空间。结论食品冷链技术的发展,不仅需要完善冷藏链的相关法律、法规及标准体系,更需要研究和开发能耗低、可靠性高且具有智能化的冷链设施和装置。对于果蔬冷链,发展智能化产地冷链装置是完善果蔬冷链的必要条件。冷链设施正常运行还需要专业的长期售后服务或巡回维护。

The purpose of this paper was to summarize the current development of the food cold chain and provide a reference for promoting the development of food cold chain. The application and research status of food cold chain technology all over the world in recent years were analyzed, and the developments in different sections of the food cold chain （pre-cooling, quick-frozen, cold storage, transport, marketing, et al.） were introduced. The results showed that there are still some problems in the technology and application of the food cold chain in China. And there is still a large room for development. In conclusion, the development of food cold chain does not only need to improve the related laws, regulations and standards, but also need to study and develop intelligentized cold chain facilities with low energy consumption and high reliability. For fruits and vegetables cold chain, it is necessary to develop intelligent cold chain facilities in the place of production. The operation of cold chain facilities requires long-term professional service and circuit maintenance.
