Problems solved by technology

This technical solution mainly utilizes that when used under high humidity, the moisture will form water droplets on the deoxidizer composition and will not cover the deoxidizer itself, so it will not affect the deoxidation performance of the deoxidizer. However, the iron-based deoxidizer must have sufficient The moisture will fully react, in the case of less water, the deoxidation performance will be greatly reduced, and when used in a low humidity environment, the effect will be worse

Abstract

The invention provides a deoxidant for foods and with a moisture-absorption function and a preparation method of the deoxidant. The deoxidant comprises iron powder, metal chloride, a water-retaining agent and a gas adsorbent. The content of the iron powder is 40-80%; the content of the metal chloride is 4-45%; the content of the water-retaining agent is 10-35%; and the content of the gas adsorbentis 0-5%. In the invention, based on a traditional iron oxidant (iron powder), the use of the metal chloride can absorb moisture in the packaging bag of the deoxidant, and maintain a dry environment in the packaging bag of the deoxidant. In the invention, the dosage of the water-retaining agent is controlled so as to ensure the moisture required by the reaction of the iron deoxidant, and the synergistic action of a plurality of ingredients can effectively avoid that the moisture generated in the use process of the deoxidant is transferred to foods so as to ensure that the deoxidant has a moisture-absorption effect, and the use of the water-retaining agent can be used for regulating the moisture in the deoxidant so as to effectively control the speed of reaction between the deoxidant and oxygen.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a food deoxidizer with moisture absorption function and a preparation method thereof. Background technique [0002] 21% of the oxygen in the air, light, temperature and humidity, moisture, microorganisms, insects, dust, etc. are the main reasons for the growth of mold and aerobic bacteria, oil rancidity, oxidation, and vitamin loss. The food deoxidizer commonly used in the market is a kind of external control preservative that can absorb oxygen in the food packaging container. Its antibacterial mechanism is mainly to absorb the oxygen in the packaging container to inhibit the growth of aerobic bacteria and the oil contained in the food. Oxidation, so as to achieve the purpose of anti-corrosion and prolong shelf life. While some foods are deoxidized, they also need to maintain the environment in the food packaging dry through physical, deliquescent or chemical moisture ...
