The change rules of sensory indexes , alcoholicity , physiochemical indexes ( total acids and total esters ) , sanitary indexes ( methanol and fusel oil ) , solids content , chromatographic bone indexes , ph values , conductivity for luzhou-flavor liquor during storage were studied .
With the development of analytic techniques , the analytic methods of fusel oil in liquor could be further improved .
随着分析技术的发展,对白酒中杂醇油的分析方法在进一步的改进。
The colorimetry of sulfuric acid and p-dimethylaminobenzaldehyde used to determinate the fusel oil of alcoholic liquor , but it occurs deviation .
测定白酒中杂醇油常采用硫酸-对二甲胺基苯甲醛比色法,但测定常有误差。
According to the rectification coefficient of the isoamyl alcohol , it is suitable for the fusel oil to be extracted in the layer of 42 % alcohol concentration in the rectification column .
由异戊醇的精馏系数理解,在酒精蒸馏过程中,从精馏塔酒精浓度42%处提杂醇油最适宜。
The bitterness substances in luzhou-flavor liquor mainly include tannin , peptide , amino acid , fusel alcohol , aldehyde , and inorganic salt .
