Preparation method and preparation system of environment-friendly food deoxidizer

Abstract

The invention discloses a preparation method and preparation system of an environment-friendly food deoxidizer, and belongs to the technical field of food freshness preservation. Polyester fibers and cross-shaped hollow polyester fibers are subjected to spunlace reinforcement to obtain first cloth; chitin fibers and polyester fibers are subjected to spunlace reinforcement to obtain second cloth; the first cloth is put in a first deoxidizing solution to be dipped and dried, and the moisture content is controlled to obtain a first base cloth layer; the second cloth is put in a second deoxidizing solution to be dipped and dried, and the moisture content is controlled to obtain a second base cloth layer; the second base cloth layer is adhered to the upper and lower surfaces of the first base cloth layer through ultrasonic hot-pressing welding by an adhesion device to obtain a fresh-keeping card; and the fresh-keeping card is put into a packaging bag and sewed to obtain the deoxidizer. The invention has the beneficial effects that: through ultrasonic hot-pressing welding, the composite cost can be reduced; and the internal space structures of the first base cloth layer and the second base cloth layer can be prevented from being damaged to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular, to a preparation method and a preparation system of an environmentally friendly food deoxidizer. Background technique [0002] Food spoilage is the most prominent problem in food quality and safety, which brings huge economic losses to the world every year. The key factor causing food spoilage is the growth and metabolism of microorganisms. Its essence is that nutrients such as proteins, carbohydrates and fats in food are decomposed by degrading enzymes secreted by microorganisms. For example, protein decomposition products include amines, hydrogen sulfide, mercaptans, indium Indole, skatole and other substances that make people disgusted after smell; fatty acid rancidity produces aldehydes, ketones, etc., and further decomposes to produce a special rancid smell. In addition, the tissue festering and mucus contamination in the shape of the food seriously affect the senso...
