What does rice bran do and what are the disadvantages of rice bran oil?

1. Laxative: The carbohydrates in rice bran do not interact with digestive enzymes in the intestines, so they have the same laxative effect as adding wheat bran.

2. Extraction of rice bran oil: Rice bran extraction of rice bran oil has been greatly developed in China, because rice bran oil is mainly unsaturated fatty acids, but also contains vitamin E, squalene, active lipase and solid plant ingredients. Rice bran oil can reduce excessive deposition of cholesterol on the blood vessel wall, which can be used for the prevention and treatment of hyperlipidemia.

The three ferulic acid antioxidants rich in rice bran oil play an important role in its antioxidant stability.

3. Extraction of phytic acid: Phytic acid usually appears in the form of calcium phytate in plants, and the calcium phytate content in rice bran can reach 10% 11%, which can usually be extracted by precipitation or ion exchange method. After the defatted rice bran is extracted from phytic acid, the residue can be used as feed, and the nutritional value is high.

4. Ferulic acid is extracted from rice bran as a food additive, which has the effect of adsorbing ultraviolet rays and preventing oxidation. The ceramide glycosides contained in rice bran have the effect of inhibiting the production of melanin, and it can be used to make cosmetics to keep it moist and white.

In the countryside there is a machine for making flour or corn flour, which comes out of one mouth with flour and the other out with bran.

Rice bran is mostly the skin of grain that is broken into pieces. Fruit peel, seed coat, outer endosperm, aleurone layer and embryo are processed, so a small amount of rice husk and a certain amount of dust and microorganisms will be mixed in the processing process, so it can only be used for feed, which is the main by-product of rice processing.

Rice bran is a mixture of seed coat, outer endosperm and aleurone layer produced when brown rice is refined into white rice. It has been determined that rice bran contains water, protein, fat, cellulose minerals, vitamins, linoleic acid and other essential fatty acids and various minerals, and is rich in nutritional value.

However, because the free fatty acids contained in rice bran are oxidized to form oxides such as aldehydes and ketones, they can affect the flavor and aroma when they are added to food. So, despite its high nutritional value, rice bran has been used as feed or for brewing.

It can be used to feed pigs and be used as water.

Rice bran oil, rice bran in the countryside, has such a magical use, but it is a pity that I only knew.

Rice bran oil is a nutritious, mild edible oil, people moderate consumption of this edible oil and no obvious appearance, it will not have adverse effects on the human body, can allow the human body to absorb a variety of minerals and vitamins, can improve the function of various organs of the body, prevent a variety of diseases.

Although rice bran oil does not exist obviously, people must not overdo it when eating rice bran oil, and if they eat rice bran oil excessively for a long time, it will also increase the cardiovascular burden of human beings, which will make high blood lipid arteriosclerosis.

and other diseases, which are very detrimental to human cardiovascular health.

The role of rice bran oil.

Rice bran oil contains a large amount of fatty acids, vitamin E

sterols, gamma oryzanol.

Vitamin E and gamma oryzanol can help remove cholesterol from the body's blood.

In this way, it can play a role in reducing blood lipids to a certain extent, which is beneficial to the health of the human body.

Rice bran oil is mainly a kind of rice oil obtained from the by-product of rice processing in the process of rice processing, which is prepared by pressing method or invasion method.

It contains a large number of ingredients needed for growth and development, such as vitamins, proteins, calcium, iron, phosphorus and other components, and moderate consumption can promote the growth and development of the human body or animals.

People's Daily Online-Make good use of rice bran oil snacks to eat great health.

The uses of rice bran are as follows:

Due to the different raw materials and processing techniques used to process rice bran, the composition of rice bran is not exactly the same. Generally speaking, rice bran contains an average of 15% protein, 16%-22% fat, 3%-8% sugar, 10% water, and about 125 1kj g of calories. Most of the main fatty acids in fats are unsaturated fats such as oleic acid and linoleic acid.

Therefore, rice bran can be further processed to extract relevant nutrients, such as combining with tofu residue to extract riboflavin, calcium phytate, and rice bran can be used to extract rice bran oil. Defatted rice bran can also be used to prepare phytic acid, inositol and dicalcium phosphate, etc.; The rice bran particles are fine and pale yellow in color. Easy to add to baked goods and other rice bran fortified foods; At the same time, due to the low content of soluble fiber.

Rice bran

It is mainly made of fruit peel, seed coat, outer endosperm, aleurone layer and embryo processing, so a small amount of rice husk and a certain amount of dust and microorganisms will be mixed in the processing process, so it can only be used for feed, which is the main by-product of rice processing. Research results and data at home and abroad show that rice bran is rich in various nutrients and physiologically active substances.

The United States and other developed countries have been edible rice bran has come out, and China has also invented similar products, that is, the application of modern food processing precision grinding technology to rice bran is not good for food rice husk, fruit skin, seed coat, dust, microorganisms, etc. and the outer endosperm such as the embryo and aleurone layer of the beneficial nutrients in the clean production workshop for precise grinding and separation.

<> many people have heard of the name rice bran in daily life, but when you want to ask what Mi Kang is, people can't give a specific answer, and they don't know what the effects and functions of rice bran are.

Rice bran is actually a plant, part of it is a by-product of the seed husk of this plant, it is composed of many parts such as exocarp and mesocarp of rice and cross-linked layer, it is also called the so-called rice bran is an important existence that can be eaten, although it looks inconspicuous, but people can absorb rich nutrients after taking it, and can also health care and prevent diseases.

1. Maintain good health.

Maintaining human health is one of the important roles of rice bran, because rice bran is rich in ceraminoglycosides, which can inhibit the production of melanin in the human body and can lighten pigmentation, so that it can be added to some cosmetics to play a significant role in lightening spots and whitening. The B and E vitamins contained in rice bran can also promote human cell regeneration, eliminate inflammation, prevent acne and acne, and nourish delicate skin.

2. Prevent urinary tract stones.

Urinary tract stones are a high-incidence disease of human beings, it is mostly related to the metabolism of trace element calcium in the human urinary system, if the trace element calcium in the urinary system can not be metabolized out of the body in time, urinary tract stones will be formed, and people can improve the excretion function of human kidneys after eating rice bran, and can promote the discharge of calcium in the urinary system, which can fundamentally prevent the occurrence of urinary tract stones.

3. Prevent cancer.

Preventing cancer is also a major effect of rice bran, because the ferulic acid contained in rice bran is a natural anti-cancer ingredient, after it enters the human body, it can be combined with aromatic alcohol in the human body, which can prevent the production of carcinogens in the human body, and can prevent cells from becoming cancerous.

Rice bran refers to a mixture of peel, seed coat and germ that is refined after rice hulling. According to the precision of processing, the quality is different, and some are doped with a small amount of chaff and broken rice. Due to the factors in rice processing, the moisture content is high, such as without dehydration treatment, it is not resistant to storage.

Rice bran is a good raw material for chicken feed, when the dry matter of rice bran reaches 87%, the crude protein content is about 13%, and the energy value is relatively high in the bran bran. Because the oil content in rice bran is high, more than 10%, and some up to 18%, most of the fat in rice bran is unsaturated fatty acids, which are easy for animals to absorb and utilize. However, this unsaturated fatty acid is prone to breakdown and spoilage, so the fresher the rice bran is used, the better.

Due to the instability of the unsaturated fatty acids in rice bran, which is easy to decompose and deteriorate, the storage time of rice bran should not be too long, not more than two weeks. If the water is large, it can not be put for a long time, and it is best to buy and feed now. In order to prolong the storage period, the degreasing treatment can be adopted, and the existing extraction method and pressing method can extend the storage time of the processed rice bran cake.

Rice bran, commonly known as green bran, is a mixture of peel, seed coat and germ removed in the process of brown rice processing plant, which is also mixed with a small amount of rice husk and broken rice. Rice bran contains 10%-18% crude protein oil, and is rich in vitamin B and minerals such as manganese, potassium, magnesium and silicon, but the content of vitamin A, vitamin C and vitamin D is less. Rice bran is a good feed for chickens, but the traditional usage is not reasonable and should be improved.

For **haowangnong*** consultation*--inquiry.

1. Appropriate amount. Feeding too much rice bran can fatten the chickens, which can reduce the reproductive performance of the breeders. In addition, because the higher content of phytate and trypsin inhibitors in rice bran is not conducive to the decomposition of crude protein, chickens will eat too much rice bran will be thin, therefore, the feeding amount of rice bran should not exceed 30% of the chicken diet, and should be reasonably matched with other fine, coarse and green feed.

2. Fresh. Rice bran has high oil content, and is susceptible to acidification and deterioration under the influence of high temperature, humidity, light and air during storage, which reduces the nutritional value and palatability of the diet, and may cause diarrhea in chickens. Therefore, aged rice bran that has been stored for too long should not be used to feed chickens.

3. Supplement calcium and phosphorus. Rice bran contains less calcium, can not meet the nutritional needs of chickens, although it contains more phosphorus, but mainly phytate phosphorus, can not be fully absorbed and utilized by chickens. Therefore, bone meal should be added to the chicken diet with rice bran, and chickens should be exposed to more sunlight at the same time to promote the absorption of calcium and phosphorus by the body.

Rice bran plus 60% corn flour added to the EM bacteria fermentation effect is better, can decompose crude protein, improve feed utilization, at the same time, EM probiotics into the chicken intestine quickly improve the intestinal digestive system to improve the system, at the same time, EM bacteria clean up the intestinal system has a good effect on the prevention of intestinal diseases.
