Abstract


Applied Research of Sichuan Provincial Education Department infrastructure projects on the basis of this article first discussed on the basis of rough set theory , rough set theory analysis method is applied to the identification of liquor flavor to discuss various low molecular weight organic acids , lipid species relationship between liquor flavor , and then discuss the relationship between the Okuma various physical and chemical indicators Daqu quality grade , the last of the the Okuma indicators and liquor yield and wine quality data fusion mining , reasoning Daqu indicators the key factors affect white wine quality and production parameters , to explore the importance of the various indicators of the influence of liquor quality and yield . The main content of this paper is as follows: 1 , the rough set theory analysis methods used in liquor flavor identification of each flavor Liquor low molecular weight organic acids , the lipid content analysis , go about the decision liquor flavor unnecessary ingredients ( attribute Reduction ) and an essential component of unnecessary ingredients value ( rule Reduction ) , a decision liquor flavor simplest ingredients and ingredient value expression , can determine the flavor of the liquor with less data : proposed a new method of analysis Daqu physical and chemical indicators Daqu quality relationship rough set theory , liquor force , the lipidated force , the aroma force ( including ammonia nitrogen and starch into force ) , caky bulk density , moisture Daqu quality and acidity of the seven evaluation indicators quantified and about less liquor force the starch into force and the acidity of the main indicators of the evaluation of the new song production in July , while the wine producing power , esterifying power and acidity evaluation 7 on the production , storage time to 30 days Daqu quality factors , also found that the quantitative relationship between these factors Daqu quality . 3, the rough set theory is applied to affect Daqu quality and production indicators of the importance factor analysis to establish the important factor in their weight Daqu physical and chemical indicators affecting the quality and yield of liquor : the esterifying power , acidity , saccharification is affected an important factor of the liquor quality , their weights were 25% , 25% , 50% ; the acidity , liquefied force and fermentation force an important factor affecting the liquor production , and its weight were 23% , 46.2% , 30.8% .
