According to the analysis of purple rice in purple clams by the Rice and Products Inspection Center of the Hunan Academy of Agricultural Sciences, purple rice in the clam is rich in protein, amino acid, starch, crude fiber, iron, calcium, zinc, selenium and other trace elements. The details are as follows:
A high protein content
The protein content of purple rice in purple clams was 1.37% higher than the average protein content of medium japonica rice (combined) approved in Hunan Province from 1984 to 2007, which was a relative increase of 15.6%.
Second, amino acid composition, nutrient-rich
Amino acids form the basis of proteins. There are more than 20 kinds of common amino acids, of which lysine, methionine, phenylalanine, threonine, isoleucine, valine, tryptophan and leucine are the human body. Essential amino acids, which cannot be synthesized by the eight amino acids, must be taken directly from food.
According to the detection of purple rice in purple clams by the Rice and Food Products Testing Center of the Hunan Academy of Agricultural Sciences, the amino acid content per 100 g purple rice in purple clams is 71.4% higher than that in Sanfeng Zaojing rice, among which: per 100 g c The lysine in purple rice (which is the first limiting amino acid) has a lysine content of 96.0% higher than that of Sanfeng Zaojing Rice.
Per 100g purple rice contains purple methionine, methionine content is higher than Sanfeng early 19 refined rice 240.7%. In addition, histidine has also been identified as one of the essential amino acids in children, and histidine is contained in 100 g of purple glutinous rice, and histidine content is higher than that of Sanfeng Zaolian 19%. This fully shows that purple rice in Ziyijie has rich amino acid content and excellent composition, which is especially suitable for the nutritional needs of children and the elderly.
Third, high starch content
Purple rice in the purple clams has a high starch content. According to the determination, the content of starch in purple clams is 70.1%, which can fully guarantee the source of human body heat. Therefore, regular consumption of purple purple rice industry, on the human liver protection and detoxification, saving protein and anti-ketone body have a certain effect.
Fourth, high cellulose content
Violet in the purple clams has high cellulose content. According to the determination, the content of crude fiber in purple clams is 1.34%. Cellulose has a filling intestine, increases fecal volume, promotes intestinal peristalsis, and promotes the secretion and reduction of digestive juice. Cholesterol absorption and other effects. Therefore, regular consumption of purple purple rice industry, to prevent arteriosclerosis, prevent colon cancer has a great benefit.
V. Rich content of trace elements
1, iron nutrition and health effects
Purple rice is rich in iron, according to the determination: per kilogram purple rice purple rice, iron content than polished rice, high 248.3%, the significance of human nutrition and health is very important.
Therefore, regular consumption of purple purple rice, to maintain the balance of iron in the body, to improve children's mental state, to focus attention, prevention and treatment of iron deficiency anemia, promote development, enhance disease resistance, prevent fatigue, make the skin recover well The blood color has a certain effect.
2, calcium nutrition and health effects
Purple rice is rich in calcium, according to the determination: per kilogram purple purple rice in the community containing calcium, calcium content than polished rice is 116.5% higher, the significance of human nutrition and health is very important.
Therefore, regular consumption of purple purple rice, to ensure the body calcium balance, prevention of colon cancer, prevention and treatment of menopausal osteoporosis, prevention of muscle spasms, lower blood pressure, protect bones and teeth from lead poisoning, maintain a strong bone It has a certain effect on healthy teeth and ease insomnia.
3, zinc nutrition and health effects
Purple rice is rich in zinc. According to the determination, the zinc content per kilogram purple rice is 81.8% higher than that in polished rice, which is important for maintaining growth and health. Therefore, regular consumption of purple purple rice, maintain human zinc balance, enhance the body's immunity, improve the body's ability to fight infectious diseases, improve the effectiveness of insulin, help prevent prostate hypertrophy in older men, accelerate the internal and external human body Wound healing, regulating the metabolism of testosterone in the prostate, preventing the disappearance of taste and smell, preventing reproductive dysfunction, eliminating white spots in nails, preventing mental disorders, and reducing cholesterol accumulation have a certain role.
4, selenium nutrition and health function
Purple rice is rich in selenium and cesium, and it contains selenium per kilogram purple rice, which is 17.8% higher than the selenium content in polished rice (the statistics of selenium content in 11 rice samples in Huaihua, Xiangxi, and Changsha). It is important to maintain growth and health. Therefore, purple glutinous rice is frequently consumed to ensure the body's need for selenium, a necessary trace mineral. It has a role in preventing the formation of free radicals in order to protect the immune system, prevent cancer, prevent hot flashes of menopausal fever and other diseases during menopause, prevent heart disease and blood circulation diseases, and prevent dandruff. Studies have shown that selenium is an essential nutrient for the human body. It is a strong antioxidant and acts like a vitamin, but it is more effective. Selenium is a component of glutathione peroxidase that prevents oxidation of unsaturated fatty acids, inhibits the production of peroxides and free radicals that can damage the body, and protects cells from damage. It has been reported that selenium plays an important role in preventing lung cancer, gastrointestinal cancer, breast cancer, esophageal cancer, and ovarian cancer, and selenium supplementation can often increase the survival rate of cancer patients.
