Problems solved by technology

[0006] When a consumer buys a bottle of beverage with a total volume of 450ml, the actual content of the beverage is only about 250ml, which undoubtedly constitutes a major psychological gap for consumers, and the product brings serious inconvenience in transportation and carrying.
[0007] ②Solid-liquid mixed self-heating packaging has a high probability of not being able to start normally
These gases are either released directly to the surrounding environment, or are sealed in the packaging system and absorbed by other materials; the hydrogen gas released to the surrounding environment may have the risk of explosion if it is in a relatively small space; if it is sealed and absorbed in the packaging, it will cause The volume of the absorbed substance re-expands, resulting in uneven pressure inside and outside the packaging volume, and the application of this product in high altitude and low pressure areas may cause the packaging to burst and crack
[0011] ④Solid-liquid mixed self-heating technology requires a long heating time
To a certain extent, the above-mentioned problems of the solid-liquid mixed self-heating technology have been overcome, but there are still defects such as insufficient heat release and gas generation during the reaction process.

Abstract

The invention discloses a self-heating composition which comprises a main heating reagent and an ignition agent zirconium powder, wherein the main heating reagent is composed of aluminum powder, chromium sesquioxide, potassium permanganate and calcium fluoride; the invention further provides application of the self-heating composition, and the self-heating composition is used for self-heating food. The self-heating composition provided by the invention not only can shorten the heating time and improve the heat release, but also can ensure the safety and stability of the system. The method is suitable for preparing the self-heating composition, and the prepared self-heating composition is further applied to the field of self-heating food.

Description

technical field [0001] The invention belongs to the technical field of food, relates to instant food, in particular to a self-heating composition and its application. Background technique [0002] With the continuous improvement of people's demand for fast food, self-heating technology, as a technology that can break the time and space constraints for heating food and beverages, has been highly sought after by consumers and even manufacturers in recent years. Self-heating technology was first used in the field of military support, and then slowly entered the civilian market. This technology has developed into multiple branches in the continuous changes in recent years, but in terms of the overall heating material, it can be divided into two major types and four subdivided technical systems, as shown below: [0003] [0004] Solid-liquid hybrid self-heating technology is the main technology type used in today's market products. Although the economic cost of its products i...
