Abstract：Packaging is one of the most important factors influencing the quality of food packaging, food shelf life of bread (shelf life) influence. Packing method may be appropriate to extend the shelf life. By changing different packaging method, packaging materials and storage conditions, we know the influence on the quality of food packaging, packaging materials and analysis of the polymer packaging methods, storage conditions and shelf-life of correlation.
In the packaging process courses on learning the vacuum packaging, packaging, principle, function and application of DNA packaging object and its influence to the food shelf life; This experiment through a month of time, to verify the effectiveness of the different packaging materials and packaging method effect on steamed bread shelf life.
Key words：Packaging ?Bread Storage
