Nutritional value of wine wine belongs to three kinds of wines with low alcohol content, low sugar and low calorie, and rich in amino acids, vitamins and inorganic salts. So what are the specific nutritional values of wine? Let's have a look! The nutritional value of wine has nutritional characteristics and complete chemical composition. It is a good source of inorganic mineral nutrients and organic vitamins, and can provide a certain amount of heat for human body. Thiamine contained in wine can restore fatigue and excite nerves; Riboflavin can promote the redox of cells and prevent oral ulcers and cataracts; Nicotinic acid (nicotinic acid) can maintain skin and nerve health and play a cosmetic role; Vitamin B6 is very important for protein metabolism, which makes fish easy to digest; Folic acid and vitamin B 12 are beneficial to red cell regeneration and platelet production; Wine also contains copper, which is related to the absorption and transportation of iron. Wine can promote the body's absorption of iron, which is beneficial to the treatment of anemia. The wine also contains p-aminobenzoic acid, which is a component of folic acid, which can promote the synthesis of red blood cells and improve the utilization rate of pantothenic acid. The content of pantothenic acid in wine is very high,1mg/L. Adults need 5 mg-10 mg every day. Pantothenic acid deficiency is easy to cause fatigue and digestive dysfunction. The high content of inositol in wine can promote the metabolism of fat in liver and other tissues, effectively prevent fatty liver, reduce cholesterol in blood, strengthen the absorption capacity of intestine and promote appetite. Wine contains a variety of inorganic salts, among which potassium can protect myocardium and maintain heart beating; Calcium can soothe the nerves; Magnesium is a protective factor for cardiovascular diseases, and magnesium deficiency is easy to cause coronary atherosclerosis. These three elements are important components of human bones and muscles; Manganese can coagulate blood and synthesize cholesterol and insulin. Red wine contains 0.04mg/L-0.08mg/L of manganese, which can regulate the metabolism of carbohydrate, fat and protein. Selenium is a strong oxidant. Together with vitamin E, it can prevent angina pectoris, myocardial infarction, hypertension and thrombosis. The selenium content in red wine ranges from 0.08 mg/L -0.20 mg/L/L, and the seven components of red wine are quite complicated. It is a fruit wine brewed by natural fermentation, which contains the most grape juice, accounting for more than 80%, followed by alcohol naturally fermented by sugar in grapes, generally 10% ~ 13%. The remaining substance is 1000, and more than 300 is more important. Other important components of red wine, such as wine acid, fruit, minerals and tannic acid. Although the proportion of these substances is not high, they are the decisive factors of wine quality. Red wine is of high quality and delicious taste because it can show the balance of organizational structure and make people enjoy the taste endlessly. Wine is not just a solution of water and alcohol, it has rich connotations: A.80% water. This is pure water in the biological sense, which is directly drawn from the soil with vines. B 9.5- 15% ethanol, which is the main alcohol. After sugar fermentation, it is slightly sweet, giving wine an aromatic taste. C. acid. Some come from grapes, such as tartaric acid, malic acid and citric acid; Some are produced by alcohol fermentation and lactic acid fermentation, such as lactic acid and acetic acid. These main acids play an important role in the acidic flavor and balanced taste of wine. Phenolic compounds. 1 to 5 grams per liter, mainly natural red pigments and tannins, which determine the color and structure of wine. 0.2 to 5 grams of sugar per liter. Different kinds of wine have different sugar contents. F. Aromatic substances (hundreds of milligrams per liter) are volatile and varied. G. amino acids, protein and vitamins (c, B 1, B2, B 12, PP). They will affect the nutritional value of wine. Therefore, moderate drinking is beneficial to human health, which can protect blood vessels, prevent arteriosclerosis and lower cholesterol.
