Abstract

The invention relates to a multi-layer self-heating food heating bag which comprises an interlayer type thin film, a heating agent A, a heating agent B, a heat conducting agent A, a heat conducting agent B, an aromatic and a hydrophilic agent; the interlayer type thin film is composed of five thin film bodies which are mutually nested and independently sealed, the five thin film layers are respectively a first thin film, a second thin film, a third thin film, a fourth thin film and a fifth thin film from inside to outside, and a first interlayer, a second interlayer, a third interlayer and a fourth interlayer are respectively formed by filler substances between every two adjacent layers of films in a space between the adjacent thin films, the first thin film is filled with a heat conducting agent A, the first interlayer is filled with a heat generating agent A and a heat conducting agent B, the second interlayer is filled with the heat conducting agent B and a hydrophilic agent, the third interlayer is filled with a heat generating agent B and the heat conducting agent A, and the fourth interlayer is filled with the heat conducting agent B, an aromatic agent and a hydrophilic agent.

Description

technical field [0001] The invention belongs to the field of fast-moving self-heating foods, and in particular relates to a multi-layer self-heating food heating pack suitable for self-heating foods such as starch, protein and dietary fiber and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the pace of life of the masses continues to accelerate, and fast-moving food has gradually entered the field of vision of fast-paced consumers. The proportion of products in the market is increasing day by day, and its economic upside is huge, and the types of self-heating food are also increasing, such as: self-heating hot pot, self-heating rice, self-heating snail noodles, etc. [0003] At present, most of the self-heating foods on the market can reach a maximum temperature of 70°C, and the duration of high temperature is a major reason affecting their sales. In response to this problem, experts in various fields have also proposed...
