This paper will simply summarize the basic conception,principle,two withdrawing air type hypobaric storage technologies,and introduce many examples as mentioned above extending in China. This paper thinks that the master mechanism of preservation of LP for fresh horticultural products effectively inhibits the activity change of manifold enzymes,which are PAL,POD,PPO,CAT,CAD,SOD et al.,affecting the maturation and caducity of fresh horticultural products during LP storage for a short period,as a result,to reduce both risk of physiology obstacle and disease and to prolong their postharvest life; for the foreseeable future Burg's hypobaric storage technology and hypobaric short period treatment technology will play an important role in the preservation on fresh agricultural products and food preservation in storage and transportation,the preliminary processing of growing area,fresh logistics,establishing the operating platform of perishable food and high business value,fresh e-business,and fresh delivery for scattered families,establishing the operating platform of fresh-cut vegetables including edible fungi and so on in China or in the world.展开更多
