Antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package and processing method thereof

Abstract

The invention provides an antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package, wherein the antioxidant hydrogen sustained-release agent comprises zinc powder, iron powder, citric acid and calcium chloride based is mass ratio according to the quality guarantee period requirement of food. (1) The formula (mass ratio) of the antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package with quality guarantee period less than 3 months is that the ratio of zinc powder to iron powder to citric acid (containing crystal water) to calcium chloride (containing crystal water) is 0.2:1.2:(1-1.5):(0.5-0.7); (2) the formula (mass ratio) of the antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package with quality guarantee period less than 6 months is that the ratio of iron powder to citric acid (containing crystal water) to calcium chloride (containing crystal water) is 1.25:(0.75-1.25):(0.5-0.75).The hydrogen sustained-release agent has the advantages of hydrogen is released slowly; a part of hydrogen is consumed through reaction, and redundant hydrogen can go out of packages to be released; and potential safety hazards caused by accumulation of hydrogen are overcome. Iron, zinc, calcium chloride and citric acid react stably, do not generate odor and harmful air, and are harmless to humanbody.

Description

technical field [0001] The invention relates to a food fresh-keeping packaging technology, in particular to an anti-oxidation hydrogen slow-release substance for oil-containing food used in air-filled packaging and a processing method. Background technique [0002] Such as silicon-calcium-carbon composite deoxidizer, which can absorb oxygen and slow down the oxidation of food substances. It can prolong the shelf life of food, and can also play a certain role in preventing oil from rancidity, preventing oxidative browning of meat, and preventing the loss of vitamins in food. The commonly used reaction principles of deoxidizers include iron powder oxidation (iron system), enzyme oxidation (enzyme system), ascorbic acid oxidation, and photosensitive dye oxidation. Most of the deoxidizers currently used are based on the oxidation reaction of iron powder. This iron-based deoxidizer can be made into a bag and put into a package to reduce the oxygen concentration to 0.01%. It is...
