Application of modified atmosphere packaging 3
Modified atmosphere packaging for baked goods and cooked products
Modified atmosphere packaging technology can be widely used for the preservation of various types of food, extend the shelf life of food, and enhance the value of food.
Baked foods include pastries, cakes, biscuits, bread, etc. The main ingredient is starch. Food spoilage is caused by spoilage caused by bacterial mold, rancidity caused by fat oxidation, aging of starch molecular structure, etc.
The gas used in the modified atmosphere packaging of these foods consists of carbon dioxide and nitrogen. Cream-free cakes are kept fresh at room temperature for 20-30 days, and moon cakes and pudding cakes are made of high-barrier composite film at room temperature for up to 60-90 days.
Microwave dishes, soy products and cooked meat products filled with carbon dioxide and nitrogen can effectively inhibit the proliferation of coliform bacteria. Keep fresh at room temperature 20 ℃ -25 ℃ for 5-12 days, after 85 ℃ -90 ℃ conditioning and sterilization, keep fresh at room temperature for about 30 days, and store at 0 ℃ -4 ℃ for 60-90 days.
