AI Technical Summary
It is difficult to achieve a close integration of rice and dishes during the processing process, and the shelf life and taste diversity are insufficient.
Use food-grade packaging materials to wrap or bundle rice and dishes in the set shape, and sterilize them after vacuum packaging. Non-cooked foods are sterilized with high temperature to ensure that the food is fully cooked. Use two-layer or multi-layer packaging to increase the quality effect.
It achieves a close combination of rice and dishes, enhances shelf life and provides a variety of flavor options for easy consumption.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of food processing, and more specifically to a prefabricated two-in-one food and its processing method. Background Art
[0002] The main reasons for the development of prefabricated foods are the fast pace of modern life, the technological progress of the food industry, and the increasing demand of consumers for convenience and health.
[0003] Prefabricated foods are divided into two major categories: prefabricated dishes and prefabricated rice.
[0004] Prefabricated dishes originated in the United States and entered the Chinese market in the 1990s. After 2020, prefabricated dishes entered a period of rapid development. The processing method is as follows: (1) preparation and treatment of raw materials; (2) food flavoring and pickling; (3) cooking and processing; (4) cooling and packaging; (5) sterilization and storage.
[0005] Prefabricated rice originated in Japan and has also developed rapidly in the Chinese market in recent years. The processing method is as follows: (1) preparation and cleaning of rice; (2) pressure soaking; (3) quantitative packaging; (4) high-temperature sterilization; (5) steaming; (6) high-temperature sterilization and storage. Summary of the Invention
[0006] The purpose of the present invention is to use industrial food-grade packaging materials to wrap the prepared rice and dishes in a preset shape, vacuum package them, and the packaged food is a cooked product, which only needs to be sterilized. For the packaged food containing non-cooked products, high-temperature sterilization is used to make the food fully cooked.
[0007] The advantages of the present invention are as follows: 1. By using industrial food-grade packaging materials to wrap the rice and dishes, the purpose of two-in-one is achieved, and products with various flavors are manufactured, which is convenient for people to eat. 2. Through secondary tight wrapping with two or more layers of protection, the shelf life effect is increased. The first wrapping is to wrap or bundle the rice and dishes with food-grade packaging materials before vacuum packaging, and the second wrapping is to put them into a vacuum packaging bag for vacuum packaging. Brief Description of the Drawings
[0008] Figure 1 It is a schematic diagram of the two-in-one food structure Detailed Embodiments
[0009] According to Figure 1 As shown, the two-in-one food is vacuum packaged after being wrapped or bundled in a set shape with food-grade packaging materials for the prepared rice and dishes. The fully cooked food is sterilized to become ready, and the non-fully cooked food is sterilized at high temperature to ensure that the food is fully cooked.
[0010] Schematic Figure 1 In (1) is a preset shape mold, which is convenient for making the preset shape of the two-in-one food.
[0011] Schematic Figure 1 Among them, (2) and (3) are food-grade packaging materials. (2) and (3) can be combined into a single-layer food-grade aluminum foil paper, or a two-layer food-grade aluminum foil paper, or a composite material of food-grade aluminum foil paper and food-grade paper. When using a composite material, the food-grade paper is located on the inner layer, which is more conducive to improving the food safety factor. Customize the size according to requirements, and use the common thickness for the thickness, which plays a role in wrapping, protecting and fixing the shape.
[0012] Schematic Figure 1 Among them, (4) is rice products, which are composed of rice, a mixture of rice and potatoes, or rice and other beans, etc., and are made by washing, soaking, draining, and seasoning. And raw products, semi-cooked products, cooked products or mixed products are used according to taste requirements.
[0013] Schematic Figure 1 Among them, (5) is dish products, which are made by washing, draining, seasoning and marinating composite products such as beans, meat, or bean and meat, etc., and raw products, semi-cooked products, cooked products or mixed products are used according to taste requirements.
[0014] The specific operations are as follows: (1) Material preparation and treatment; (2) Washing, soaking, draining, and seasoning of rice products, and making raw products, semi-cooked products, cooked products or mixed products according to taste requirements; (3) Washing, draining, seasoning, and marinating of dish products, and making raw products, semi-cooked products, cooked products or mixed products according to taste requirements; (4) Using food-grade packaging materials to wrap or wrap and tie the adjusted rice products and dish products according to the set requirements; (5) Vacuum packaging with a vacuum packaging bag; (6) Sterilization of fully cooked products is completed, and non-fully cooked products are sterilized at high temperature and ensured to be fully cooked.
