不同酒精度对白酒在碱性条件下加热变色吸光度值的影响

Effect of alcoholicity on changes of absorbance of heated pure grain liquor under alkaline conditions

以温和酒业纯粮固态发酵白酒为研究对象,对不同酒精度及不同比例的纯粮固态发酵白酒进行了碱性加热条件下酒体变色试验。试验结果表明,不同酒精度对变色试验的吸光度值有明显影响,呈良好的线性关系。该法在实际应用时应限定酒精度。

The liquor produced by pure grain with solid-state fermentation from Wenhe Liquor Co., Ltd. was used as main material for research. Heat induced colour changes of liquor with different alcoholicity and produced by different ratios of grains under alkaline conditions were studied. The results showed that alcoholicity significantly affected the absorbance of liquor, with good linear relationship. Alcoholicity should be controlled when the method practically applies.
