Analysis of the Effect of Daqus Physical and Chemical Parameters on Liquor Quality Using Rough Sets
Daqu is important for Chinese liquor production, and it determine the yield as well as quality of Chinese liquor. Daqu can be evaluated through the physical and chem ical indicators such as the esterifying power(EP), liq uefying power( L P ), saccharifying power( S P ), fermenting power(FP), acidity, starch and moisture. These charac ters have different effect in liquor production. Duqus sig nificant physical and chemical attributes affected on liquor quality are studied using rough set theory. The information table has been built with these seven physical and chemi cal indicators of Daqu as conditional attributes, with the Chinese liquor quality level as decision attribute. The table are quantized and reduced, then it is shown that the acid ity, esterifying power and saccharifying power are the main indicators impacting on the liquor quality. Based on the conception of weight, we find that the weights of three in dicators are 25％, 25％ and 50％, which indicates that, the saccharifying power has most effect on the liquor quality, while the effects of acidity and esterifying power are the same.
