How is rice formed and how is rice made?

The first thing to do is to plant seedlings.

Wait for the seedlings to grow up

Will pick up the millet

When the millet is ripe.

Peel off the shell. It's rice.

I pulled it out and it was the freshest.

Thai fragrant rice.

Suddenly! Little sister, you are Bu is nagging fever Mai.

Some small problems are also being promoted, I faint you.

Rice is a finished product made of rice after cleaning, hulling, milling, and finishing the finished product. The cleaning process is to use appropriate equipment, through appropriate technological processes and proper operation methods, to remove all kinds of impurities mixed into the rice, so as to improve the quality of the finished rice products, and at the same time use magnets to remove iron nails and iron filings in the rice to ensure production safety. The hulling process is to use a rubber roller huller or an emery husk to take off the husk of the rice and separate the husk from the brown rice.

The rice milling process is to use a rice mill to mill and rub brown rice to separate the cortex and endosperm, and then carry out brushing, bran, crushing, drying and other treatments, so that the required grade of rice can be obtained.

Rice is grown as rice. Rice seedlings are inserted from the water, and the rice seedlings grow up, and the sleeves come out of the ears, and the ears are ripe, which is rice, and then dried and ground out to become real rice.

Rice is grown into rice, and when the rice matures, it is dried and ground out to make rice.

Hello, let me answer your question, before answering your question, I want to tell you about a poem called hoe. In the afternoon of hoeing day, sweat drops into the soil. Who knows that Chinese food is hard work.

A poem by Li Bai, you should know how this rice came about, how does it mean that he must go through farming, and then grow into rice, and then the rice will be beaten into rice. Although it is easy to say, the process inside is quite complicated, that is, if it is heavy, it needs to be fertilized, and pesticides must be sprinkled, and so on. Therefore, how rice is made is the hard work of the farmer uncle.

Rice is made from rice.

1. The origin of rice, from the perspective of species distribution, about 50,000 years ago, early rice plants have appeared in Yunnan. Therefore, it is speculated that the earliest area of rice cultivation in Asia should be the Yunnan region.

2. Archaeological discoveries in Hunan Daoxian County and Wannian County in Jiangxi Province show that humans began to cultivate and eat about 13,000 years ago, and humans should have chewed the whole rice plain by mouth before the Neolithic period.

3. There is evidence of rice cultivation in the Hemudu site excavated in the lower reaches of the Yangtze River. As early as 7,000 years ago, the original inhabitants of the lower reaches of the Yangtze River in China had fully mastered the cultivation technology of rice and took rice as the main food.

4. In the middle and lower reaches of the Yangtze River, the Hemudu culture entered the Neolithic Age after about 7,000 years, and the invention of the pestle and mortar was applied, and human beings knew how to clean and separate the chaff and rice bran that were not good for eating. Shortly thereafter, it should be found that washing the slag with water is a more efficient process of removing impurities and cleaning the process, and the efficient sterilization and removal of oxidized bran layer and dust in the rice washing process are still in use, and the pestle and mortar rice making equipment is still used until the seventies of the twentieth century.

5. In the nineteenth century, the non-roller rice machine was invented, and the rice milling efficiency was greatly improved. In the mid-twentieth century, the blast rice machine came out, and the rice milling effect was greatly improved.

6. After the twentieth century, such as the rapid development of rice making technology in the Qing Dynasty, the continuous improvement of the level of automatic cleaning of photoelectric color sorting, coupled with the continuous expansion of japonica rice planting in the cold regions of the north, in 1988, the rice was produced on a large scale in the second rice factory of the Grain Bureau of Daqing City, Heilongjiang Province.

1. At the turn of the Yin and Zhou dynasties more than 3,000 years ago, rice spread from China's Zhoushan Islands to North Korea, Japan, and south to Vietnam. During the Han Dynasty, Chinese rice was introduced to the Philippines. In the 5th century AD, rice was introduced from Iran to Western Asia and then from Africa to Europe.

After the discovery of the New World, it spread from Africa to the Americas and the world.

2. Rice, also known as rice, is a food made of rice after cleaning, hulling, rice milling, finished product 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, and is the main food of the people in most parts of China.

3. After long-term storage, due to the influence of temperature and moisture, various changes will occur in the starch, fat and protein in the rice, which will cause the rice to lose its original color, aroma and taste, reduce the nutrients and eating quality, and even produce toxic and harmful substances (such as aflatoxin, etc.).

4. The storage forms of rice include hairy rice, brown rice and refined white rice, the first two are in a living state and have a long storage period, while the latter is inanimate and should not be stored for a long time.

Historical records show that as early as 7,000 years ago, evidence of the existence of rice was found in the Hemudu site in the lower reaches of the Yangtze River, and our ancestors had a good grasp of rice cultivation technology, and regarded rice as the main food to fight against nature.

I don't know exactly when it appeared, I just know that we need to be in awe of Grandpa Yuan Longping.

Question 1: What is the structure of rice? Ordinary rice (unmilled V rice) is composed of three parts: skin, endosperm and embryo, the endosperm accounts for the vast majority, the embryo is located at the lower end of the abdomen, the embryo and the endosperm are not very tightly connected, and it is easy to fall off when milling.

However, the distribution and content of the chemical components contained in each component of rice are very uneven, and each has its own characteristics. The cortex is the protective tissue of the endosperm and embryo, containing cellulose and fat. There are many proteins and minerals, but they generally need to be removed during processing due to poor water absorption, long cooking time, and poor taste.

The endosperm is the main component of rice, containing a large amount of starch and protein, is the traditional retention object in the processing process, the embryo as the primary and meristem of rice, is the strongest part of the physiological activity of the grain, the embryo is rich in protein, fat, soluble sugar, vitamins, gamma oryzanol, selenium, furfural, trivalent chromium, cellulose, nuclease, trace elements and other substances. It is beneficial to anti-diabetes, anti-cardiovascular disease, liver protection, heart protection, and protection of the brain and nervous system. According to relevant information, the nutrients contained in rice embryos account for more than 70%.

It can be seen that its nutritional value is high.

Question 2: What is the composition of rice? Rice is very nutritious and is one of the main foods of the Chinese people.

Taking japonica rice as an example, per 100 grams of japonica rice contains grams of protein (protein food), grams of fat, grams of carbohydrates, grams of crude fiber, 7 mg of calcium (calcium food), 136 mg of phosphorus, mg of iron (iron food), 1 mg of vitamin B1, vitamin (vitamin food) B2 mg, 1 mg of niacin, 1 mg of methionine, 394 mg of valine, 610 mg of leucine, 251 mg of isoleucine, 280 mg of threonine, 394 mg of phenylalanine, and 122 mg of tryptophan, lysine 255 mg and many other nutrients.

Question 3: What is the structure of rice seeds? Rice seeds are made up of embryos and seed coats. Rice is rice seeds that remove the seed coat, and what remains is the embryo. Hence the embryo.

Question 4: What is the composition of water in rice This water is alkaline, because it washes off the nutrients of the rice skin, so it can be used to water plants, which will have a good effect; Moreover, the water molecules of rice washing water can well separate grease, clean dishes and chopsticks, remove the odor of the chopping board, and wash off the rust on the kitchen knife. In fact, in daily life, rice washing water is not only a natural stain remover that can play a "multiple role", but also has good medicinal value.

Question 5: Which part of the rice seed structure is the rice endosperm.
