Remove the methanol in your own white wine as follows:

One is to use fresh, undamaged raw materials and raw materials containing less pectin.

The second is to use less pectinase bacteria and strains of bacteria as saccharification agent.

Three, the raw materials containing more pectin pretreatment, can be used to steam stuffing, such as hulls steam 30 minutes, can be removed from the hulls of methanol.

Four, is to reduce the steam pressure of raw materials, increase the amount of exhaust steam and raw materials by soaking, can remove part of the soluble pectin.

Fifth, the use of natural zeolite or molecular sieve treatment that can adsorb methanol can reduce the methanol content in the finished wine.

Because the boiling point of methanol is 64.7 degrees, which is lower than the boiling point of alcohol 78.3 degrees, the content of methanol in the head of the wine is higher, and the process of slow steaming, more to the head of the wine or the setting of the methanol fractionation tower when steaming the wine can reduce the content of methanol in the finished wine. Raw material pre-soaking treatment can also remove part of the soluble pectin, which can reduce the methanol content in liquor and improve the hygienic quality of liquor.

Expanded information:

Methanol mainly affects the central nervous system, eyes and acid-base balance of the human body, for example, it can cause dizziness and fatigue, blurred vision, vision loss, drowsiness and other situations. First of all, acute formaldehyde poisoning is usually the accidental consumption of formaldehyde-containing beverages or alcohol.

Secondly, there may be inhalation of large amounts of formaldehyde vapor, usually manifested as blurred vision, central nervous system symptoms, combined with liver function damage, cardiac arrhythmia, renal function damage, metabolic acidosis, etc., and if the poisoning is more serious will also result in the emergence of blindness, retinal congestion and edema, optic nerve papillae edema, and delirium, coma and other situations.

Chronic methanol poisoning can appear visual field defects, optic nerve atrophy and so on, there may be symptoms of vegetative nerve dysfunction.
