Abstract: In order to provide basic information for hypobaric storage, a brief overview of the hypobaric storage theory was made in this paper. In this article, firstly, decompression preservation with storage-confined space pressure, vacuum low- pressure system, cryogenic refrigeration system, the humidity adjusting system and measurement and control systems were analyzed; secondly, the characteristics, the research progress abroad and the development course of the hypobaric storage and its application effect on fruit and vegetable preservation were introduced objectively; thirdly, the restrictive problems in the study of hypobaric storage, such as pressure, dehydration and flavor fades, were discussed; finally, the development direction in the future of the decompression preservation of storage was pointed out.
