The rice in the self-heating pot is rice; it is a finished product made from rice grain after cleaning, hulling, milling, finishing and other processes, rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients required by the human body, as well as being the main foodstuffs for the people of most parts of China.

Rice contains about 75% of carbohydrates, 7%-8% protein, 1.3%-1. 8% fat, and rich in B vitamins. Carbohydrates in rice is mainly starch, the protein contained is mainly rice gluten, followed by rice gliadin and globulin, its protein biomass price and amino acid composition ratio are higher than wheat, barley, millet, corn and other cereal crops, digestibility 66.8%-83.1%, but also in the cereal proteins in a higher one.

Extended information:

Rice protein contains less lysine and threonine, so it is not a complete protein, and its nutritive value is not as good as animal proteins. However, consuming rice at lunch and dinner is more conducive to weight loss than pasta. In the south of China, people generally eat rice as a staple food, while in the north there is a big difference.

Evidence of rice cultivation exists at the Hemudu site excavated in the lower reaches of the Yangtze River. The earliest rice growers in the history of rice were the Chinese ancestors in the lower reaches of the Yangtze River. As early as 7,000 years ago, the primitive inhabitants of the lower reaches of the Yangtze River in China had already fully mastered the technology of rice cultivation and used rice as their main food.

Hemudu culture in the middle and lower reaches of the Yangtze River entered the Neolithic Age about 7,000 years later, when the invention of mortar and pestle was applied, and humans knew how to clean up and separate the hulls of the grain from the chaff, which was not good for food. Shortly thereafter, it should be found that washing with water is a more efficient cleaning process to remove impurities, washing the rice process to remove oxidized chaff layer and dust, people are still in use, mortar and pestle rice production equipment until the 1970s is still in use.
