Fusel oils are called a by-productfermentation. They are contained as an admixture in raw alcohol and have a very unpleasant characteristic odor. They represent an oily liquid, which can have a color from light yellow to reddish-brown. The main constituent of this substance is alcohols C3-C9, as well as aldehydes, furfunol and fatty acids.
When making home-made drinks with highthe alcohol content of these impurities is quite acute. Distillation of moonshine is made using special equipment. Pre-prepared braga. Then it heats up to a high temperature. As a result, alcohol vapors begin to be released. Upon cooling, the latter condense and drain into a previously prepared container.
During distillation, it is very important to observe the heating mode. Light impurities contained in the brew start to boil at a temperature of about 68 degrees. Further, at a temperature in 78 aboutC, there is intense evaporation of ethyl alcohol. At the subsequent heating up to 85 aboutWith the original product, the unwanted fusel oils themselves begin to be released.
At this stage, you must be extremely careful. First, care must be taken to ensure that the temperature of the barge does not rise above 83 aboutFROM. Otherwise, as already mentioned above, fusel oils will start to be released from it. Secondly, at this stage the evaporation of ethyl alcohol occurs, as a result of which its content in the brew gradually decreases.
In the future, the resulting moonshine for removalThe oils that have fallen into it can be further purified. For this, a variety of methods can be used. The simplest is the purification of moonshine by potassium permanganate. To do this, it is first diluted in water. A liter of moonshine requires about 1-2 grams. The resulting solution is poured into the moonshine and left to stand for 10-12 hours. After clarification and precipitation, the liquid is filtered through a tissue.</ p>
