Miscellaneous alcohol oil, also known as senior alcohol, is a general term for a class of mixtures with high boiling points, mainly including n-propanol, isobutanol, isoamyl alcohol, active amyl alcohol, etc. Miscellaneous alcohol oil in wine is generated by a series of biochemical reactions between amino acids and sugars contained in brewing raw materials during the fermentation process. Its components have their aroma and taste, and its total amount and the proportion of the content of various alcohols directly affect the liquor flavor, so the wine cannot be without miscellaneous alcohol oil.
However, its excessive content can lead to headaches and dizziness. It is slow to oxidize and decompose in the human body, and its toxicity is stronger than that of ethanol, and it tends to increase with the increase of carbon number. Proper control of the fusel oil content in liquor is crucial to the improvement of liquor quality and the health of consumers. Therefore, the content of miscellaneous alcohol oil in wine should be strictly controlled within the national standard: 60 degrees distilled liquor with miscellaneous alcohol oil content not exceeding 0.20 g/100 mL.
In the alcohol industry, senior alcohol is often regarded as impurities. Senior alcohol is easily soluble in alcohol, and insoluble in water, similar to oil when the alcohol is low, so it is often called miscellaneous alcohol oil. Miscellaneous alcohol oil is one of the essential hygiene indicators for wine.
