Technical Field

The invention relates to the technical field of food-related product processing, in particular to an alcohol preservation card with a deoxidation function and a preparation method thereof.

Background

Spoilage of food products is a result of oxidation of the food product and the proliferation of microorganisms and insects such as mold, bacteria, yeast, etc. Food oxidation is caused by the direct action of oxygen, and the breeding of microorganisms and insects is also closely related to oxygen. In order to prevent the food from going bad, manufacturers adopt a method of putting a deoxidizer into food packages, oxygen in the packages can be removed, the propagation of microorganisms and insects is inhibited, the food oxidation is slowed down, the shelf life of the food is prolonged, the deoxidizer is effective on the oxidative rancidity of aerobic bacteria and grease, inorganic iron-based deoxidizers are commonly used as the deoxidizer, but the food with the inorganic iron-based deoxidizer cannot meet the requirement of food safety detection when passing through a metal detector. Thus, organic deoxidizers such as those containing (iso) vitamin C series proposed in CN106418109A, an organic deoxidizer, have appeared; the deoxidizer is effective in oxidative rancidity of aerobic bacteria and grease, but is ineffective to microorganisms such as yeast, anaerobic bacteria and the like, and the volatile alcohol with a certain concentration can effectively inhibit the propagation of the microorganisms such as the yeast, the anaerobic bacteria and the like, for example, a card type alcohol preservative which is synthesized by paper sheets and breathable plastic stickers and is proposed by CN101260633A (alcohol preservative packing paper and preparation method thereof).

In order to combine the effects of the deoxidizer and the alcohol preservative and effectively prolong the shelf life of food, a packaging material with double functions of deoxidation and alcohol preservation, which is proposed by CN110037225A A Multi-effect active packaging material combining oxygen absorption and alcohol preservation, is also provided. However, the packaging material with double functions proposed by CN110037225A, a multi-effect active packaging material combining oxygen absorption and alcohol preservation, has complex structure and difficult manufacture; CN106387603A soak solution for preparing mildew-proof tablets, mildew-proof tablets and preparation method thereof, proposes a card type alcohol preservative taking a glucolase oxidation system as a deoxidation material, but the cost of the manufacturing raw materials is higher.

In conclusion, the prior art for manufacturing the card type alcohol preservative with the double functions of deoxidation and alcohol preservation has the following defects: firstly, the cost of the preparation raw materials is high; secondly, the preparation process is various, and the efficiency is low in mass production.
