Environmentally friendly deoxidizer and preparation method thereof

Abstract

The invention relates to the technical field of deoxidizers, in particular to an environmentally friendly deoxidizer and a preparation method thereof. The environmentally friendly deoxidizer comprisesthe following raw materials by weight: 60-90 parts of vegetable oil residue, 0.5-1.5 parts of metal salt, 1-3 parts of water absorbent resin, 5-9 parts of white carbon black, 2-4 parts of vermiculite, 0.5-4 parts of activated carbon and 5-15 parts of water. The metal salt is replaced with catalytic enzyme. The environmentally friendly deoxidizer achieves a deoxidizing function by adopting the metal salt or the catalytic enzyme to catalyze reaction of oil in the vegetable oil residue with oxygen, and is good in deoxidizing effect. Further, the raw material vegetable oil residue can be purchased in large quantities and is low in price and easy to obtain. A formula is environmentally friendly and non-toxic, so that the deoxidizer not only has the fresh-keeping effect but also causes no harmto the human body, and does not pollute the ecological environment.

Description

technical field [0001] The invention relates to the technical field of deoxidizers, in particular to an environment-friendly deoxidizer and a preparation method thereof. Background technique [0002] At present, the series of deoxidizers at home and abroad include inorganic and organic systems. Among them, the inorganic system is mainly based on reduced iron, while the organic system is based on ascorbic acid and sodium ascorbate. At present, the deoxidizers in the market are mainly reduced iron. Although the toxicity of reduced iron is very low, there have been cases of skin allergies caused by eating deoxidizers in food packaging by mistake, and these deoxidizers form hard lumps after oxidation. , are difficult to biodegrade, and have a certain impact on the ecological environment; deoxidizers that use ascorbic acid and sodium ascorbate as the main raw materials have slow oxygen absorption speed, poor fresh-keeping effect, high cost, and are difficult to accept in the mark...
