Complex atmosphere of a small packaging Preservation
Modified atmosphere packaging technology and its products more than 34% market share, and its agricultural products, fruits, vegetables, and large industry super f continued on page 83) Table 1 Comparison of the shape the quality of freeze-dried jujube Paul Moss ■ Storage study shows that: to date and to nuclear integration as a product of nuclear half-date, freeze time-consuming,[link widoczny dla zalogowanych], energy consumption, high cost. After the uneven quality of freeze-dried, crisp Difference. Product main color is red,[link widoczny dla zalogowanych], freeze-dried after the loss of luster, color,[link widoczny dla zalogowanych], dim. Ring date films, a rectangular sheet date, date bar, date D thickness of the 4 kinds of products only 5mm, freezing and drying time is very short, low energy consumption, relatively low cost. Even after the freeze-dried quality, crisp and delicious. Product main color is light green. Freeze dried and bright colors. Good quality but in the shape of a rectangular sheet date processing, material losses large. The date shall, after the consumption of freeze-dried jujube D but not too convenient. More comprehensive analysis of factors fierce. To date, as a freeze-dried product into the market, positioned as a pre-ring date of 42 film better fruit quality of freezing temperature on freeze-dried samples of the pre-freeze date, the purpose is to date all of the meat frozen into ice water, pre-freeze must be dates through the cold, so that all internal mechanical bond into ice water,[link widoczny dla zalogowanych], or through fierce unfrozen. Dates there will be a small amount of liquid under vacuum, the liquid will evaporate, causing the material shrinkage. Variety of other processes with the same date, different freezing temperature on the quality of the results in Table 2, Table 2; East junction temperature; East dry fruit quality of comparative studies have shown that T increases in the process of freeze-dried jujube, freezing temperature should be reasonable. General Pre-freezing temperatures are high, slow freezing; pre-freezing temperature is low. Freezing speed. The faster the freezing, ice crystals in the date the smaller meat, not easy to damage cells, that high nutrient preservation, dried small hole formed in uniform, time-consuming freeze-dried,[link widoczny dla zalogowanych], freeze-dried dates of good quality; freezing rate slower coarse ice crystals formed in the pulp and may lead to a large degree of cell damage and further injury nutrition. After sublimation drying in a dry hole is also larger, shorter time-consuming freeze-dried, freeze-dried jujube 5 Conclusion relatively poor quality of the development freeze by date multi-link control, multi-factors. Every aspect and every - 32 order will be subject to serious study. Ding Yi explore the best parameters. After the study. Pre-freezing temperature in a 25 ~ CI. ~ /, T. Freeze-dried product quality and stability. Less nutrient loss will be positioned as a freeze-dried dates of the ring shape sheet date, both for plus T, and easy to eat. Beautiful shape, beautiful colors, the overall effect is good
