The efficacy of rice:
Traditional Chinese medicine believes that rice is sweet in taste and flat in nature, and has the effects of tonifying the middle warmer, strengthening the spleen and stomach, nourishing essence and strengthening the brain, harmonizing the five internal organs, dredging blood vessels, quenching thirst, improving eyesight and stopping diarrhea. Known as the "head of the five grains", it is the main grain crop in China, accounting for about a quarter of the cultivated area of grain crops. Half of the world's population lives on rice.
Rice, which enters the spleen, stomach and lung meridians, has the functions of invigorating the middle energizer, nourishing yin and moistening the lung, invigorating the spleen and regulating the stomach, and relieving polydipsia. Ancient health experts also advocated "morning porridge" to produce fluid. Therefore, patients with cough and constipation caused by lung yin deficiency can cook porridge with rice in the morning and evening. Drinking rice porridge often contributes to the growth of body fluid and can relieve discomfort such as dry skin to some extent. If you add some pears when cooking porridge, the health care effect of traditional Chinese medicine will be better.
In terms of species distribution, early rice appeared in Yunnan about 50,000 years ago. Therefore, it is speculated that the earliest rice planting area in Asia should be Yunnan. Archaeological discoveries in Daoxian County, Hunan Province and Wannian County, Jiangxi Province show that human beings began to grow and eat about 13000 years ago. Before the Neolithic Age, humans should have chewed the whole rice with their mouths.
The Hemudu site excavated in the lower reaches of the Yangtze River has evidence of rice cultivation. In the history of rice, the earliest people who planted rice were the Chinese ancestors in the lower reaches of the Yangtze River. As early as 7000 years ago, the primitive residents in the lower reaches of the Yangtze River in China had completely mastered the rice planting technology and took rice as their staple food.
Hemudu culture in the middle and lower reaches of the Yangtze River entered the Neolithic Age about 7000 years later, and Chu Jiu's invention was applied. People know how to clean and separate inedible chaff and rice bran. Soon, it should be found that water elutriation is a more effective impurity removal and cleaning process. The effective effect of rice washing to remove bacteria, oxidized chaff and dust is still in use today, and the rice manufacturing equipment in Chu Jiu was used until 1970s.
/kloc-The roller-less rice mill was invented in the 20th century, which greatly improved the rice milling efficiency. In the mid-20th century, the air-flow rice mill came out, and the rice milling effect was greatly improved. With the rapid development of rice-making technology in the late 20th century, the level of photoelectric color selection and automatic cleaning has been continuously improved. With the continuous expansion of japonica rice planting in the cold areas of northern China, the second rice-making plant of the Annual Grain Bureau has produced 1988 wash-free rice on a large scale. 1989 50 tons/day production line put into production.
1998, washing-free rice was invented by using ultra-low temperature sterilization and dust removal technology. 1999, Zhaoyuan rice mill of Beidahuang Group produced the first generation of non-washed rice. The product patent invention of "Mizhen" 20 10 marks a new era of rice processing. In 20 1 1 year, "rice oil" and "defatted rice oil" were invented. In 20 12, China's rice output was 1 1.387 million tons, an increase of 29.56% over the same period of last year and 13.79% over the previous month. During the period of1-1,the cumulative rice output in China reached 96.379 million tons, an increase of 2 1.97% over the same period of last year.
China's grain imports will continue to grow. It is estimated that the annual grain imports will exceed 60 million tons, and half of the global exports will be shipped to China. Based on the total grain output of 20 1 year of 57 1, 2 1, 000 tons, the total grain imported in 20 12 years will account for more than 10.5% of China's total grain output.
65% of the population in China lives on rice, which plays an important role in national food security. In 20 10, China's grain planting area was 10987 million hectares, an increase of 890,000 hectares over the previous year. Rice is one of the most important grain crops in China, accounting for more than 30% of the national grain planting area. In 20 10, the national rice output was 82.444 million tons, up 30.5% year-on-year.
With the acceleration of urbanization in China, at least 200 million rural people will still move to cities and towns in the future, and the demand for rice in cities and towns will greatly increase, and the change of urban consumption structure will indirectly consume more food.
Compared with other industries, the development of rice industry in China is small in scale and poorly organized. The field of rice processing is dominated by small production, small workshops and vendors, and there are few big brand enterprises and leading enterprises, so the market concentration is low. With the deepening of economic globalization, China's huge market consumption power will attract more and more international rice brands, and the competition in the domestic rice market will become increasingly fierce.
The arrival of the era of brand consumption has given birth to high-end rice industry. China consumers are stepping into the era of brand consumption from the era of daily consumer goods. In addition, the frequent exposure of "poisoned rice and aged grain" by the media has increased people's concern about the safety and quality of rice, and the market potential and development space are increasingly obvious.
What happened to society? ! Makes people feel insecure. People in the past had good moral quality and could be trusted. People's moral quality is the same as the raw materials of the goods they manufacture and sell. Therefore, people are more and more truly aware of the truth that "only the quality and quality of the vegetables and fruits they grow and the livestock and poultry they raise can be trusted, and the food they make can be assured".
