Cooked and frozen food pre-packaging container and cooked and frozen food heating method

Abstract

The invention discloses a cooked and frozen food pre-packaging container and a cooked and frozen food heating method. The container comprises an upper sealing membrane and a container body. The upper sealing diaphragm comprises a sealing diaphragm body and a pressure reaction bonding layer matched with the eave edge on the container body; a product information identifier and an identification code are printed on the sealing diaphragm body, the identification code is printed by a food-grade irreversible temperature discoloration material, and food cooking information is stored in the identification code; the pressure reaction bonding layer is arranged on the outer edge of the lower surface of the sealing diaphragm body. The structure for judging whether the food is frozen repeatedly is arranged at one end of the container, so that whether the cooked frozen food in the pre-packaging container is frozen repeatedly can be judged; and whether the pre-packaged container is heated or not can be judged by observing the color change of the identification code. And meanwhile, the microwave oven accurately heats the cooked and frozen food in the pre-packaging container according to the cooking information stored on the identification code, so that an accurate, rapid and safe heating mode is realized.

Description

technical field [0001] The invention relates to the technical field of frozen food safety, in particular to a prepackaged container for cooked frozen food and a method for heating the cooked frozen food. Background technique [0002] Pre-packaged cooked frozen food is a new consumer variety born in line with people's pursuit of delicious, diversified, convenient, fast, and easy-to-buy food in modern society. It is also an industry that has developed rapidly in recent years. As we all know, repeated thawing and refreezing of frozen food, heating, cooling and reheating will not only spoil the food, but also bring adverse effects on people's health. Therefore, the problem of repeated freezing and reheating of prepackaged cooked frozen food not only involves the quality and safety of the food, but also involves the popularity of prepackaged cooked frozen food and the development prospects of the industry. [0003] The principle of microwave heating is that the microwave acts on...

AI Technical Summary

Problems solved by technology

Microwave ovens are especially suitable for heating pre-packaged cooked and frozen foods because of their rapid heating, no open flame, and no waste heat. , the taste becomes worse, and the essence of the food must be restored by precisely controlling the heating time, firepower, and humidity according to the weight and material of the prepackaged cooked and frozen food
