Supermarket shelf life is we buy shelves, an important reference factor, however, often, not to the shelf shelf life. It has been very bad, it is because we rarely pay attention to the maintenance of the shelf. How to extend the shelf life, has become a new direction of scientific research workers.
Generally speaking, article packaging can use vacuum, inflatable, cling film, general packaging 4 packaging forms. Through the contrast test of different packaging methods under normal temperature under different packaging and packaging, determination conditions of supermarket shape and physicochemical indexes, the comprehensive evaluation, the effects of different packaging on the shelf life of the supermarket. Reported the influence to prolong the shelf life of meat packaging, the results of the study indicate that, at room temperature, inflatable packaging within 96 ~ 120h of fresh pork has good preservation effect, vacuum packaging of common packaging and packaging group is better than that of fresh-keeping film packing.

At present, many researchers have been out of the impact, emphasizing the single factor on the traditional means of prolonging the shelf life of the old warehouse and began to consider the comprehensive effect of various factors in the external storage, testing, such as acetic acid spraying method to extend the shelf life of mutton natural phytochemicals in meat preservation application. The application of microwave also prompts people to improve the level of science and technology will open up many effective ways for the extension of shelf life.
