The efficacy, function and eating method of rice, rice is an indispensable staple food in our daily life, so the nutrition of rice has a great effect on our health, so the efficacy, function and eating method of rice are introduced below.

Efficacy, Function and Edible Method of Rice 1

Alias: rice

Taboo crowd: People with diabetes eat less.

Suitable for people: the general population can eat it.

Basic introduction of rice

Rice is the finished product of rice after washing, hulling, milling and finishing. The cleaning process is to remove all kinds of impurities mixed into rice by using appropriate equipment, appropriate technological process and appropriate operation methods, so as to improve the quality of finished rice, and at the same time, remove nails and iron filings from rice by using magnets to ensure production safety. The husking process is to remove the glume of rice with rubber roller husker or emery husker, and separate the glume from brown rice. In the process of rice milling, brown rice is milled and kneaded by a rice mill to separate the cortex from the endosperm, and then milled, shelled, broken and dried to obtain the rice with the required grade.

Rice consists of husk, pericarp, seed coat, exoendosperm, aleurone layer, endosperm and embryo. Brown rice refers to the product that removes the chaff and keeps other parts; Polished rice (commonly known as rice) refers to the product that only the endosperm is retained and the rest is completely removed. Because most nutrients except carbohydrates (such as protein, fat, cellulose, minerals and vitamins) in rice are concentrated in pericarp, seed coat, exoendosperm, aleurone layer and embryo (commonly known as sugar layer), the nutritional value of brown rice is obviously better than that of polished rice. With the popularization of nutrition science knowledge, brown rice has been paid more and more attention and loved by people, and it is regarded as the nemesis of "civilized disease", and a craze for eating brown rice is gradually taking shape.

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. Although there is evidence of rice cultivation in a site excavated in the lower reaches of the Yangtze River, it does not mean that the ancestors of China in the lower reaches of the Yangtze River were the earliest rice growers. Therefore, the following statement cannot be accepted. 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.

Efficacy and function of rice

1, basic food for supplementing nutrition

Rice porridge has the effects of invigorating spleen, regulating stomach and clearing lung heat.

2. Infant supplementary diet

It is beneficial to the development and health of infants, can stimulate the secretion of gastric juice, help digestion and promote the absorption of fat, and can also promote casein in milk powder to form loose and soft small clots, which are easy to digest and absorb.

Nutritional value of rice

1. The main component of rice is about 70% carbohydrate, and it also contains a certain amount of protein 7%~8%, vitamins, cellulose and minerals.

2. The nutritional value of rice is general and balanced, and the content of vitamin B group is rich and complete. However, in the process of rice processing, a lot of nutrients may be lost. Generally speaking, the more refined the rice is, the more nutrients are lost. Therefore, the nutritional value of standard two meters is one meter higher than standard two meters, and the nutritional value of brown rice is two meters higher than standard two meters.

3. In rice protein, alkali-soluble gluten with high lysine content accounts for 80%, and the lysine content is higher than other grains, and the amino acid composition ratio is reasonable, which is close to the best amino acid ratio model in protein recognized by the World Health Organization. The biological value (BV value) of rice in protein is 77, and the utilization rate (PER value) of rice in protein is 2.2 (1.5 for wheat and 1.65438 for corn).

The purchase of rice

1. Look at the hardness: the hardness of rice is determined by the content of protein. The hardness of rice is stronger, the protein content is higher and the transparency is better. Generally, new rice is harder than old rice, low decimeter is harder than high decimeter, and late indica rice (japonica rice) is harder than early indica rice (japonica rice).

2, look at the white belly: there are often opaque white spots on the abdomen of rice. White spots are called heart white in the central part of rice and outer white in the outer abdomen. Belly white rice is low in protein content and contains more starch. Generally, rice with high water content, immature rice and immature rice after harvest has a big white belly.

3, look at waist explosion: waist explosion is caused by the loss of balance inside and outside after the rice grains suddenly appear heated during the drying process. Fried rice tastes rotten and endogenous, and its nutritional value is reduced. Therefore, when selecting rice, we should carefully observe the surface of rice grains. If there are one or more transverse cracks on the rice grain, it means that it is popcorn.

4. Look at the yellowing of rice grains: The yellowing of rice grains is caused by chemical reactions of some nutrients in rice under certain conditions, or by microorganisms in rice grains. The smell and taste of these yellow grains are very poor, so be sure to observe the number of yellow grains in rice when purchasing.

5. Look at the new era: the aging phenomenon of rice is serious, the color of old rice becomes darker, the viscosity decreases, and the original flavor of rice is lost. Therefore, we should carefully observe the color of rice grains. The rice with gray powder or white grooves on the surface is old rice, and the more it is, the older it gets. At the same time, pick up the rice and smell it If it smells moldy, it means old rice. In addition, see if there are insect-eaten particles in the rice. If there are moth-eaten grains and insect carcasses, it means old rice.

6. Look at the label: When you buy rice, you should also pay attention to the contents marked on the package. For example, whether the product name, net content, names and addresses of manufacturers and distributors, production date and shelf life, quality grade, product standard number, special labeling contents, etc. are marked on the package.

Storage of rice

1. Store rice with garlic

There are many storage methods to prevent rice from insects, and garlic storage method is one of them. Peel garlic, put it in a bag with rice, and sterilize, repel insects and kill acaroid mites. In addition, star anise can play a similar role, but it is best to break it by hand first, and then add rice to make its effect more obvious.

2. Store rice with white wine

Insert the wine bottle vertically into the center of the rice, open the lid so that the mouth of the wine bottle is slightly higher than the rice surface, and then seal the rice. In order to make the wine bottle stand firmly and seal in the rice, it is suggested that the rice should be placed in a sealed container with a lid as far as possible, not in a bag.

3. Pepper stores rice

Zanthoxylum bungeanum has a special pungent smell. This fragrance can be used to repel insects, so it is also advisable to store rice with pepper.

Specifically, there are two ways to choose: one is to put a proper amount of pepper (generally 40 capsules) in the pot, and then add more water than the water needed to soak the rice bag. Heat the water, let it cool, soak the rice bag in pepper water for about 5 minutes, and then take it out to dry. Then add the rice. Rice can be stored for a long time without worms. Second, put the pepper into gauze or thin cloth with good air permeability and wrap it into several small bags, then put the small bags evenly in all corners, and then tie the bag mouth tightly.

How to eat rice

The frequency of rice washing should not be too much, so as not to affect the absorption of nutrients.

The efficacy, function and eating method of rice 2 1, which helps digestion.

Rice has a sweet taste, which can stimulate honey in gastric juice, help digestion and promote fat absorption. It is ideal to make milk powder with rice soup or give it to your baby.

2. Spleen and stomach

Rice enters the spleen, stomach and lung meridians, and has the effects of strengthening the spleen and stomach, nourishing yin and moistening the lungs, and nourishing the middle energizer. Used in porridge or rice soup, it has a good spleen and stomach strengthening effect.

3. Maintain blood sugar balance

Rice is rich in vitamin B 1, inorganic salts and high dietary fiber, which plays an important role in maintaining blood sugar balance.

4, moistening the intestines and relaxing the bowels

Crude fiber molecules in the rice bran layer contribute to gastrointestinal peristalsis and have a good therapeutic effect on constipation and stomach diseases.

5, lower blood pressure

Rice contains high-quality protein, which can keep blood vessels soft and lower blood pressure when used in porridge or rice soup.

Step 6 lose weight

Rice is a food with low calorie, low salt, low fat, protein and high carbohydrate, and it also contains crude fiber. You can lose weight with whole grains, soybeans, vegetables and lean meat.

7. Taboo of rice.

1, rice diet is not suitable for people who have undergone colon resection and renal insufficiency;

2. Rice porridge is cooked without alkali. Alkali will destroy vitamin B 1 in rice. Lack of vitamin B 1 susceptibility to beriberi.

3. You can't eat polished rice without brown rice for a long time, because polished rice will lose a lot of nutrition during processing, leading to nutritional deficiency.

8. Nutritional value of rice

1, the amino acid composition of rice is relatively complete, and protamine is the main component in protein, which is easy to digest and absorb.

2. Rice is rich in B vitamins, which is an important dietotherapy resource to prevent beriberi and eliminate oral inflammation.

3, spleen and stomach, essence, body, thirst, diarrhea.

When rice is cooked in porridge, there is a thick and slippery paste on it. This is rice oil, called porridge oil. It is a top-grade tonic, which is most suitable for patients, parturients, the elderly and the infirm.

5, if you take this rice oil alone with a little salt on an empty stomach, the effect is better.
