The feeling above is that my head is dizzy and heavy, as if it were going to explode. Good wine is generally not on the top, and it is generally not good wine on the top.
There are many reasons for dizziness and dry mouth after drinking white wine. It is mainly caused by the uncoordinated proportion of aldehydes, methanol, fusel oil and other substances in alcohol and acid esters. For example, fusel oil decomposes slowly after entering the human body, so when fusel oil content is high, people are easy to drink. In foreign countries, fusel oil is called the root of drunkenness. Generally speaking, "good wine doesn't go to the head", and the top is not good wine.
1, aldehydes in liquor
Aldehydes have fragrance, while lower aldehydes have strong pungent odor. Acetaldehyde is a pungent source in liquor, and its content should not be too high. If you overdo it, white wine will have strong irritation and spicy taste, and you will feel dizzy after drinking this white wine. Drinking alcohol containing free acetaldehyde often makes my throat dry. This is because the pharmacological action of acetaldehyde in the body is several hundred times stronger than acetaldehyde. It can accumulate in the body, forcing peripheral blood vessels to dilate, causing facial blood to swell and central blood vessels to contract, thus accelerating the heartbeat and raising blood pressure, making people dizzy and painful. This is one of the important reasons why liquor is drunk.
Acrolein, commonly known as glyceraldehyde, is not only hot and dazzling, but also has a persistent bitter taste, and is the king of spicy taste. Acrolein is a kind of tear substance, which is very harmful to human body. In Turkey, alcohol containing acrolein is needed to prepare wine.
2. Fusel oil in liquor
Fusel oil is a heterogeneous mixture with high boiling point, which has a particularly strong pungent smell and does more harm than good in taste. If the content is too small, the style of traditional liquor will be lost. If the liquor-based liquor treatment is very clean, that is, there is no or very lack of higher alcohols, the taste of liquor is very light, which makes liquor have no mellow feeling; Too much will lead to acridity and bitterness, which will have a bad influence on wine and be harmful to human body. Its toxicity and anesthetic effect are stronger than that of ethanol, which can make the nervous system congested and make people have a headache, and its toxicity will increase with the increase of molecular weight. The oxidation rate of fusel oil in the body is slower than that of ethanol, and the residence time is longer, which is another reason for the dry mouth of liquor. The main components of fusel oil are isoamyl alcohol, amyl alcohol, isobutanol and propanol, among which isoamyl alcohol and isobutanol are the most toxic. If the harm degree of ethanol to human body is 1, then the harm degree of propanol to human body is 3.5, that of isobutanol is 8, and that of isoamyl alcohol is 19.
Step 3 add spices
We know that all asymmetric C atoms can form isomers. For example, lactic acid has isomers, which are two different substances. Liquor is optically active, not racemic, and the optical rotation is sometimes positive and sometimes negative. Some isomers are comfortable to drink, while others are uncomfortable to drink, which is also one of the reasons for headache and dry mouth.
4. Reasons for drinking.
Most of the alcohol-based functions used in low-grade liquor are ordinary edible alcohol, and the national standard is isoamyl alcohol.
5, health indicators exceed the standard.
5. 1 GB2757-8 1 requires lead <1mg/l. If it exceeds the standard, it is easy to cause lead poisoning, mainly chronic poisoning, with symptoms such as headache and dizziness.
Manganese < 2 mg/l is required in GB 2757-8 1. Although manganese is a necessary trace element for normal metabolism of human body. Excessive manganese entering the human body can cause poisoning. Chronic manganese poisoning is characterized by central nervous system dysfunction, dizziness, some accompanied by slight headache and memory loss.
6. Acid ester balance.
Acid ester balance is a traditional feature of China liquor. Most famous liquors in China follow the law of high acid and high ester, so people have little side effects after drinking. Maotai-flavor liquor is the most typical representative of high-acid and high-ester liquor in China. Famous foreign distilled spirits have low acid value esters. What's more, "Odek" liquor contains no acid value esters or very few. From the acid ester analysis of these wines, we can see the mystery of acid ester relationship. At present, some middle and low-grade new wines on the market add a lot of exotic esters, but ignore the adjustment of acidity, resulting in serious defects such as discomfort after drinking and large side effects, which is also one of the factors that cause the dry mouth and astringency of liquor.
To sum up, the main reasons for dry mouth and head of liquor are high acetaldehyde content, high fusel oil content, uncoordinated proportion of acid esters, excessive sanitary indicators, poor quality of added spices and alcohol. Good wine is generally not on the top, and it is generally not good wine on the top.
