What are the effects and functions of rice bran oil?

Rice bran oil has a relatively high nutritional value. It can properly improve cardiovascular and cerebrovascular diseases and lower blood lipids. It is good for human skin and promotes blood circulation. People with endocrine disorders can use rice bran oil to regulate their endocrine system. Many people use rice bran oil as a cooking oil, which is healthier to eat. Don't worry. Many people still don't understand rice bran oil. Let's take a look at the effects and functions of rice bran oil.

1. Nutritional value of rice bran oil

1. Rice bran oil has high nutritional value. In developed countries such as Europe, America, South Korea, and Japan, it is a healthy and nutritious oil that is as famous as olive oil. It is deeply loved by people with hyperlipidemia and cardiovascular and cerebrovascular diseases, and has long become a daily healthy cooking oil for Western families.

2. China is rich in rice bran oil raw material resources, but the production and consumption of rice bran oil is still in its infancy, with an annual output of less than 120,000 tons. Experts suggest accelerating the development of rice bran oil so that this healthy and nutritious oil can enter people's daily lives as soon as possible. High nutritional value.

2. Ingredients

1. Jiang Xinzheng, senior engineer of the Oil Engineering Technology Research Center of the State Grain Administration, told our reporter that rice bran oil is a type of edible oil with high nutritional value. The composition of rice bran is 15% to 22% oil, which is equivalent to the oil content of soybeans, 12% to 16% protein, 33% to 53% nitrogen-free extract, 7% to 14% moisture, and 8% to 12% ash.

2. Brown rice is rice grains without the husk. It consists of three parts: the bran layer, the embryo and the endosperm. The bran layer accounts for about 7.5% of the total weight of the brown rice, and the embryo accounts for about 2.5%. The rice bran layer is composed of pericarp, seed coat, endosperm and aleurone layer. The oil in brown rice is mainly concentrated in the endosperm of the germ and rice bran layer, especially in the germ.

3. Rice bran oil is a nutrient-rich vegetable oil with an absorption rate of over 90% after consumption. The fatty acid composition, vitamin E, sterols, oryzanol, etc. of rice bran oil are beneficial to the human body's absorption. It has the beneficial effects of clearing cholesterol from the blood, lowering blood lipids, and promoting human growth and development. Therefore, rice bran oil is a nutritious and healthy oil recognized both at home and abroad. At the same time, due to the good stability of rice bran oil itself, it is suitable as frying oil, and can also be used to make margarine, shortening and high-grade nutritional oil.

4. Rice bran oil contains about 38% linoleic acid and 42% oleic acid. The ratio of linoleic acid to oleic acid is about 1:1.1. From the perspective of modern nutrition, oils in this ratio have higher nutritional value.

3. Efficacy

1. Rice bran oil is rich in oryzanol, which is a family of compounds composed of more than a dozen sterol ferulic acid esters. It can prevent the body from synthesizing cholesterol, lower the concentration of serum cholesterol, promote blood circulation, regulate endocrine and autonomic nerves, and promote the growth and development of humans and animals. Oryzanol can promote microcirculation in the skin, protect the skin, and is also effective in treating diseases such as concussion.

2. Rice bran oil also contains a large amount of fat-soluble vitamins, sitosterol and other plant sterols and other nutrients from rice bran and germ.

3. At the same time, vitamin E and oryzanol both have antioxidant effects, which makes rice bran oil more oxidatively stable and easy to store.
