In recent years, wine experts have conducted in-depth research on the composition and medicinal value of yellow rice wine, and have a further understanding of its health care function. Scientific research shows that yellow rice wine is rich in protein and amino acids. It is rich in protein, and the protein in Shaoxing yellow rice wine is 16g per liter, which is four times that of beer. Moreover, protein in yellow rice wine is easily absorbed and utilized by human body after being degraded by microbial enzymes. Yellow rice wine also contains 8 kinds of amino acids necessary for human body. According to statistics, every liter of rice wine contains 3400 mg of essential amino acids and 2960 mg of semi-essential amino acids, while the essential amino acids in beer and wine are only 440 mg or less.
Secondly, yellow rice wine is rich in inorganic salts and trace elements. Inorganic salts in human body are necessary to constitute body tissues and maintain normal physiological functions, and can be divided into macro elements and trace elements according to their contents in the body. Up to now, 18 inorganic salts have been detected in yellow rice wine, including many macro elements such as calcium, magnesium, potassium and phosphorus, and trace elements such as iron, copper, zinc and selenium. According to the survey of China Nutrition Society, due to the restriction of food structure, the zinc deficiency rate of China residents is as high as 50%. Zinc deficiency in human body can lead to low immune function, loss of appetite, spontaneous loss of taste, rough skin and hair loss. Adults need about 12.5mg of zinc every day, and drinking yellow wine can just supplement the human body's demand for zinc. In addition, the daily selenium intake of China residents is far from the daily intake recommended by the World Health Organization. The selenium content of yellow rice wine is about 12 times higher than that of red wine and about 20 times higher than that of white wine, and it is safe and effective, which can effectively help human body to supplement selenium deficiency.
Besides, rice wine is also rich in vitamins. Vitamins in wine come from raw materials and autolysate of yeast. Rice wine is mainly made of rice and wheat. Besides abundant B vitamins, the content of vitamin E in wheat embryo is as high as 554 mg/kg. In addition, during the long-term fermentation of yellow rice wine,
