Abstract

The invention provides a special food oxygen absorbent for tapioca balls and a preparation method of the oxygen absorbent, and relates to the field of oxygen absorbents. The oxygen absorbent is prepared from the following components in parts by weight: 20-40 parts of Fe-MOFs, 30-50 parts of beta-cyclodextrin, 5-10 parts of microcrystalline cellulose, 1-3 parts of an oxygen-absorbing auxiliary agent, 0.1-2 parts of a thickener, 2-4 parts of a dehumidifying agent, 60-80 parts of a filler, 55-70 parts of ethanol, and 120-150 parts of deionized water. The oxygen absorbent provided by the inventioncan completely remove oxygen, quickly reduce the concentration of oxygen in a packaging bag to 0.01% or below in a short time, and maintain a long-time oxygen-free state, does not change the appearance, taste, and smell of the tapioca balls, can be used with confidence without being ingested into bodies along with food, and is very safe.

Description

technical field [0001] The invention relates to the field of oxygen absorbers, in particular to a special food oxygen absorber for rice noodles and a preparation method thereof. Background technique [0002] Oxygen absorber, also known as oxygen scavenger, deoxidizer, is an additive that can absorb oxygen and slow down the oxidation of food. It is a new product currently being used in food preservation. It is a group of chemical mixtures that react easily with free oxygen or dissolved oxygen. It is packed in a sealed paper bag with a certain degree of air permeability and strength. Like a desiccant bag, it is sealed and packaged with food in a food bag and can be removed The oxygen remaining in the air in the bag prevents food from oxidative discoloration, deterioration and oil rancidity, and also inhibits the growth of mold, aerobic bacteria and food pests. At present, deoxidizers are not only used to maintain food quality, but also used for preservation and rust preventio...
