Abstract

The invention relates to a heating composition and application thereof, the heating composition is composed of a component I and a component II, the component I comprises 4-40% of epoxidized soybean oil, 4-30% of epoxy resin, 2-10% of vermiculite, 0.05-3% of A1 type ethyl maltol and 0.05-3% of peppermint essence, the component II comprises 2-30% of polyamide, 0-8% of polycarboxylic acid anhydride and 2-15% of vegetable oil, and the heating composition is prepared by mixing the components according to a certain proportion; the heating composition is used for food heating, is not limited by time and places, is free of open fire, does not produce hydrogen, is safe and reliable, emits heat for a long time, is high in heating efficiency, is rapid and controllable in exothermic reaction, is environment-friendly and sanitary, can be well applied to the field of instant food, can produce fragrance capable of increasing appetite, and is high in cost performance.

Description

technical field [0001] The invention relates to a heating composition and its application, belonging to the technical field of food self-heating. Background technique [0002] With the acceleration of the pace of social development today, portable food has become popular, but there are still a lot of inconveniences in the process of eating for urban white-collar workers who eat at their workplaces and people who do outdoor activities and travel. In order to combine the portable characteristics of food with convenient Combining heating methods to overcome various constraints, self-heating food has become a trend. It uses flameless chemical heating technology to realize the self-heating function of packaged food and meet social development and people's needs. [0003] At present, self-heating food on the domestic market has been favored by many consumers, and has become a common "net celebrity food" for outdoor travel and family gatherings. However, self-heating food has also ...
