Firewood, rice, oil, salt, sauce, vinegar, and tea describe seven important items in life, and "vinegar" is one of them! Vinegar can be used for marinating and scenting dishes, and can also be diluted as vinegar to make your diet more delicious. The Food and Drug Administration invites experts to let the hosts who go to the daily cooking team understand vinegar better and enjoy the beauty of "jealousy" together.
{9 Assistant Professor Wang Shangda of three categories: vinegar, vinegar and synthetic vinegar, said that according to the production method of vinegar, vinegar can be divided into three categories: vinegar, vinegar and synthetic vinegar. vinegar is made of natural raw materials such as grains and fruits; vinegar is made of additional flavor ingredients for vinegar, and the packaging must be clearly marked as "vinegar" to divide it into vinegar; synthetic vinegar is made by using food additives glacial acetic acid or acetic acid as the main ingredients, and then adjust the flavor and acidity.The raw materials for vinegar can be divided into two categories: grains and fruits. Ceramic vinegar is mostly made of rice and glutinous rice in Taiwan, such as white vinegar and glutinous rice vinegar; in China, there are products made of sorghum and rice vinegar, such as Shanxi Chen vinegar; vinegar that uses fruits as raw materials are commonly seen in red wine vinegar, basamike vinegar, and apple vinegar made of apples.
When vinegar is produced through two stages of microbial fermentation in manufacturing, vinegar mainly provides sour substance "acetic acid", which needs to be generated through two different microbial fermentation procedures. First, yeast fermentes sugars into alcohol, and then acetic acid bacteria then repels alcohol into acetic acid. Taking the most commonly used white vinegar in Taiwan as an example, rice is used as raw material, first treated with enzymes, so that the powder in the rice becomes glucose, and then yeast is added to ferment to produce alcohol. After the alcohol fermentes to a certain extent, the alcohol concentration is adjusted to a concentration suitable for the growth and action of acetic acid bacteria, and the acetic acid bacteria are added to produce acetic acid. The final product is vinegar.The Food and Drug Administration also supplements that some vinegar will pass the mortar step, allowing the alcohols that were originally decomposed in the vinegar to react with acetic acid or other organic acids to produce esterification, forming ester substances such as ethyl acetate. These newly generated products can make the vinegar more flavorful. In addition, some products will regenerate the moisture in the vinegar, which will make the vinegar more depressed.
There is something to say about jealousy! When adding the machine, you often need to add some vinegar to draw the dragon's eyes! But when is it best to add? Assistant Professor Wang Shangda said that the main components of vinegar are acetic acid, as well as the flavored substances produced during the fermentation process, such as short-link amino acids, ester and organic acids. These ingredients are easily heated, so the best time to use is to add them before cooking is almost finished or is about to serve, so that the fresh and delicious taste of the vinegar can be completely preserved.The storage method of vinegar is very simple. Generally, acetic acid is very strong and microorganisms are not easy to grow. Do not directly be exposed to strong light after opening the bottle and seal it in the yin place.
Is it a myth to drink vinegar in the middle to adjust the acidic senile quality? In fact, the theory of acid stool quality is not scientifically based. The human body itself is a large buffering system that can maintain the body's acid stool. Even if you drink a lot of vinegar, it will not make the body acidic or stool-like.In addition, some products will emphasize that vinegar contains health-friendly ingredients and the benefits of drinking to the body. Wang Shangda said that even if vinegar can produce health-friendly ingredients during the production process, the concentration is not high after being diluted. It is recommended to be regarded as a general appetite for drinks without expecting health benefits. Wang Shangda also reminded that people with weak stomachs should not drink on an empty stomach to avoid excessive irritation of the stomach.
