my country has a very long history of edible vinegar. Records of vinegar can be found as early as the Shang and Zhou dynasties. China is one of the main birthplaces of vinegar. It is generally believed that my country began mass production of vinegar around the 8th century BC. During the Spring and Autumn Period of my country, vinegar had spread to every corner of people's lives. During the Northern Wei Dynasty, there were records of detailed brewing methods of vinegar. During the Tang and Song Dynasties, my country's vinegar brewing technology led the world. Vinegar is a sour seasoning produced by various ferments. Its chemical formula is CH3COOH and it is a weak electrolyte. Rice or sorghum is mainly used as raw material for making vinegar. Appropriate enzymes can convert liquids containing carbohydrates (sugar, starch) into alcohol and carbon dioxide. The alcohol is then acted upon by certain bacteria and combines with oxygen in the air to produce acetic acid and water. Therefore, the process of making vinegar is the process of further oxidizing alcohol into acetic acid. Vinegar has a sour and mellow taste, and a fragrant and soft liquid. It is an indispensable condiment in cooking. Its main ingredients are acetic acid, higher alcohols, etc. The main types of vinegar currently used are "rice vinegar", "smoked vinegar", "special vinegar", "sweet and sour", "wine vinegar", "white vinegar", etc. Depending on the origin and variety, the amount of acetic acid contained in vinegar is also different, generally between 5 and 8%. The intensity of the sourness of vinegar is mainly determined by the amount of acetic acid it contains. Digestible fat and sugar: Vinegar contains substances such as amino acids and organic acids. Amino acids can promote the conversion of excess fat in the body into energy consumption, and can also digest sugar and protein absorbed by the body, allowing metabolism to proceed smoothly. It can be said that drinking vinegar appropriately can not only help you lose weight, but also promote the burning of nutrients in the body, improve the utilization rate of heat energy, and promote physical health. Please tell me more specifically. There are many classifications of vinegar. For example, according to its use, it can be divided into cooking vinegar, health-care vinegar, beverage vinegar, etc. The most common type is cooking vinegar. This type of vinegar has a rich and mellow flavor and can effectively remove the fishy smell in food. Eating vinegar can stimulate the appetite and aid digestion. It is an indispensable condiment in our daily life. |
