Anonymous users2024-02-15No matter what kind of wine, in short, if it is wine, there is alcohol, the common name of alcohol is ethanol, the chemical formula is C2H6O, and the simple structure formula is CH3CH2OH. Of course, there is no such statement. The change in the arrangement and structure of a molecule is determined by the change in the state of the substance it is composed of.
In the case of a gaseous substance, its molecular arrangement is very loose and the gravitational repulsion of each other is weak. And liquor, no matter how long it is placed in the kiln, it will not become solid, right? The molecular arrangement of solid matter is very tight.

Anonymous users2024-02-12The chemical name of the wine is ethanol, commonly known as alcohol, the structure is CH3CH2OH or C2H5OH, and the molecular formula is Tong Zhengfan C2H6O, which is an organic compound, which is a volatile colorless transparent liquid at room temperature and pressure, which cannot be drunk directly, and has a wide range of uses in chemical, medical, food, agricultural production and other industries.
What was the first country to make wine.
The earliest country to make wine is China, China has a long history of winemaking and drinking, and the word "wine" and wine-related records have appeared in the oracle bone inscription.
As early as the primitive society, human beings knew that they used grains, melons and fruits to ferment and make wine.
In the West, it is mainly Guqing closed liquor, which uses the brewing method of maltosaccharification and yeast, and it was not until the introduction of koji from China that the process of making liquor with maltosaccharide was broken.

2. Food refers to food that can be eaten by humans. Wine belongs to the beverage category in the food category, and naturally belongs to food.
3. The chemical composition of liquor is ethanol, which generally contains trace amounts of fusel and esters, and the concentration of edible liquor is generally below 60 degrees (i.e. 60%) (a few have more than 60 degrees), and the liquor is purified to more than 75% for medical alcohol by fractionation, and purified to absolute ethanol for the above. Liquor is made by fermentation of grain.
4. China is the earliest wine-making country, as early as 2000 years ago, the wine-making technology was invented, and constantly improved and perfected, and now has developed to be able to produce various concentrations, various aromas, all kinds of alcohol-containing beverages, and for industry, medical and health and scientific experiments to produce medical alcohol and anhydrous ethanol with a concentration of more than 95%.
5. As a brewery and liquor factory, the health license and product quality are managed by the food inspection institute (sanitary mouth). There are two types of standards that must be met for food quality: product standards and hygiene standards. Among them, the health standard is a national mandatory standard and must be implemented.
