Abstract

The invention discloses a method for preparing alcohol by honey, which comprises the step of extracting the alcohol by distilling mature fermented mash. The mature fermented mash is prepared according to the following steps: the honey is diluted by water to obtain a diluted sugar liquid; a flocculating agent is added into the diluted sugar liquid, and a clear sugar liquid is obtained after a precipitate is filtered; the clear sugar liquid is diluted by water to obtain a diluted clear sugar liquid; and ammonium sulfate containing 21 percent of nitrogen and industrial phosphoric acid containing70 percent of nitrogen are added into the diluted clear sugar liquid respectively, and alcohol yeast is added after the diluted clear sugar liquid is stirred evenly to obtain the mature fermented mash. The method has the advantages of simple process, high utilization rate of raw materials, wide sources of the raw materials, no land competition with grains and so on, and provides a brand-new production raw material and a method for alcohol production.

Description

technical field [0001] The invention relates to a method for preparing ethanol, in particular to a method for preparing ethanol by biological fermentation. Background technique [0002] At present, the methods for preparing ethanol mainly include synthetic method and biological fermentation method, and the biological fermentation method is divided into: ethanol from starch, ethanol from molasses, and ethanol from cellulose according to the raw materials used. When using molasses as raw material to prepare ethanol, sugarcane molasses or beet molasses are mostly used, and there is no report on using honey as raw material for ethanol production. The main component in honey is sugar, which is basically a supersaturated aqueous solution of sugar. The water is the natural water left in the honey after it is brewed and matured. The water content is 16%-25%. The water content of honey is below 18%, and it can be stored for a long time under sealed conditions without fermentation or...
