Green environment-friendly biological deoxidizer and preparation method thereof

Abstract

The invention discloses a green environment-friendly biological deoxidizer. The deoxidizer consists of aerobic food microorganisms, a culture medium, a water-retaining agent and a carrier. The deoxidizer comprises the following components in parts by weight: 0.25-5 parts of aerobic food microorganisms, 70-90 parts of the culture medium, 1-10 parts of the water-retaining agent, and 2-10 parts of the carrier. The green environment-friendly biological deoxidizer utilizes the aerobic food microorganisms, which automatically become resting bodies after oxygen is consumed up, stop metabolism, do notform any other gaseous pollutant, and do not pollute wrapper objects. Meanwhile, the method adopts waterproof breathable films as a wrapping material which does not absorb the moisture of the wrapping objects, and the moisture required by the microorganism metabolism is brought by the culture medium, so that the risk of fluctuation of moisture content of products is avoided. In the process of using the products, no additional equipment investment is needed, and all the components of the deoxidizer are degradable and environmentally friendly. Therefore, the deoxidizer has economic and environment-friendly beneficial effects.

Description

technical field [0001] The invention relates to the technical field of deoxidizers, in particular to a green and environment-friendly food deoxidizer and a preparation method, which is suitable for deoxidizing packaging bags or packaging containers in the food field. Background technique [0002] Deoxygenated packaging is a commonly used packaging technology in the food field. The functions of deoxygenated packaging include preventing the growth of aerobic microorganisms, preventing the oxidation and deterioration of food ingredients, and maintaining the flavor of food, etc. The deoxidation methods currently include physical deoxidation, chemical deoxidation and biological deoxidation. [0003] Physical deoxidation includes modified atmosphere packaging and vacuuming. Modified atmosphere packaging fills the packaging container with inert gas to drive away oxygen, replace it with inert gas, and then seal it to isolate oxygen. Commonly used inert gases are nitrogen, carbon ...

AI Technical Summary

Problems solved by technology

The problem with physical deoxygenation packaging is that it requires a large amount of equipment investment and the packaging process costs are relatively high

The problem with chemical deoxidation packaging is that chemical reagents can easily cause food contamination

However, this patent has the following defects: the first microorganism used is active dry yeast, which belongs to facultative anaerobic microorganisms. After the oxygen in the packaging container is consumed, it will continue to undergo anaerobic metabolism to form metabolites such as ethanol, which will not only change food flavor, which will lead to food contamination and pose a food safety risk; secondly, water-absorbing materials and water-permeable membranes are used in the design, and water-absorbing materials will absorb water from the packaging objects, thereby changing the water content of the product and posing a threat to product quality stability
