Problems solved by technology

[0003] On the other hand, if the above ingredients are mixed and then packaged, the material will absorb oxygen in the environment during the process from mixing to packaging, thus greatly depleting the oxygen absorption performance, and sometimes, the oxygen absorption performance loss is close to 20%.
In order to ensure product performance, deoxidizer manufacturers have to increase the amount of deoxidizer, which increases the cost

Abstract

The invention provides a deoxidizing preservative. The deoxidizing preservative comprises the following components in percentage by weight: 85 to 95 percent of oxygen absorbent and 5 to 15 percent of water; the oxygen absorbent is blocky solid and comprises the following components in percentage by weight: 40 to 90 percent of ultrahigh molecular weight polyethylene, 5 to 55 percent of oxygen absorbing substance and 5 to 20 percent of active carbon, wherein the oxygen absorbing substance is one or a mixture of reduced iron powder, ferrous chloride, ferrous carbonate, ferrous sulfate and zinc powder. The deoxidizing preservative not only prevents food pollution caused by powder leakage, but also prevents materials from adsorbing oxygen in the environment in the processes from mixing to packing so as to greatly lose oxygen absorption performance and reduce the production cost for manufacturers of the deoxidizing preservative.

Description

Technical field: [0001] The invention relates to the technical field of externally controlled fresh-keeping of food, in particular to a deoxidizing fresh-keeping agent and a preparation method thereof. Background technique: [0002] At present, the deoxidizing preservatives produced by most enterprises at home and abroad use reduced iron powder, activated carbon, water-absorbing agent or catalyst as the main components, and are packaged with perforated film, perforated composite film, and misplaced perforated film. Since these substances are all powdery substances, if the perforated film is used for packaging, the powdery substance is easy to leak from the film holes and cause powder leakage to contaminate food. Although the products packaged in perforated composite film and misplaced perforated film can avoid the phenomenon of powder leakage, due to the limitation of the production process, there are often false seals in the sealing area and insufficient temperature and pre...
