Description

TECHNICAL FIELD

[0001] The utility model belongs to food preservation technical field, especially a kind of alcohol package for food preservation. BACKGROUND

[0002] Food alcohol preservative is a kind of external control preservation product widely explained in food industry, especially baking industry. Generally, high-moisture products are prone to food mold, microbial reproduction, etc. The traditional way is to add preservatives to extend the shelf life. With the improvement of people's living standards, green, clean external control preservative products gradually replace internal control preservative additives. In recent years, the use of deoxidizing agent, alcohol sheet and other external preservation products has increased rapidly, especially in the baking industry. Alcohol sheet has inhibitory effect on aerobic and anaerobic bacteria.

[0003] However, the deoxidizing preservative on the market has the following shortcomings:

[0004] 1. Powder type deoxidizing agent has the problems of powder leakage and spots, which will affect the hygiene and flavor of food. Such abnormal products have poor preservation effect on food and even cause food to be inedible.

[0005] 2. Alcohol products generally have uncontrollable evaporation speed. The alcohol evaporates too fast in a short time, resulting in too heavy alcohol smell in the food bag. The short-term evaporation rate is too fast, which cannot meet the needs of maintaining alcohol concentration for medium and long shelf-life products.

[0006] 3. At the same time, the part of alcohol sheet in contact with food will have obvious bitter taste, and the smell and taste of food will be poor after opening the bag.

[0007] 4. The card type structure of alcohol sheet is prone to jam during processing, which will cause high abnormal rate and low production efficiency.

[0008] 5. The alcohol inside the alcohol sheet may be squeezed out under negative pressure. If the squeezing problem occurs during production, it will increase the rework cost. If the squeezing problem occurs during food packaging, it will affect the quality of food.

[0009] In view of the above problems, it is urgent to develop an alcohol package product with controllable alcohol evaporation speed and no liquid penetration. UTILITY MODEL CONTENT
