The following points must be highly valued in the development of Luzhou-flavor liquor production techniques: full and objective understanding of liquor development trend in China; further study of Luzhou-flavor pure-grain liquor production without addition of external flavoring substances; elimination of off-flavor in base liquor; persistence in increasing natural growth quantity of ethyl caproate; proper understanding of the relations of liquor-making and liquor blending to advance better development of liquor-making industry.

必须全面、准确、客观地认识中国白酒的发展方向；努力实现浓香型纯粮白酒不添加外加香的目标；解决基酒中的怪杂味；坚持走以增加己酸乙酯的自然生成量为主的质量之路；正确对待白酒的酿造与勾调工作，才能把握和发展浓香型白酒的生产工艺，全面推进白酒业的进步。

With the fermenting very well,and improve Ethy1 caproate content by 500～800mg/L,and improve liquor quality by 2～3fens,and make the base liquor's characteristics of Luzhou-flavor liquor very well,Especially the additi.

在转型期间，添加活性干酵母和糖化酶，可以大大缩短转型期，在生产中添加活性干酵母，可以使主发酵期缩短2~5d，糟醅发酵更彻底，出酒率平均提高3.33%，同时，使酒中己酸乙酯平均提高500~800mg/L，酒质提2~3分，基酒具有很突出的浓香型主体香特征，特别是在度夏醅中使用，可以降低酒醅中的酸度，有效地防止掉排现象。

The approaches to improve the quality of new craft liquor were summed up as follows: proper selection and treatment of raw materials including alcohol, seriflux, food additives, heading liquor, and ending liquor etc.; scientific liquor body design including the relations between microconstituents and ethyl caproate in Luzhou-flavor lqiuor and the formula of new craft liquor etc; use of traditional liquor production techniques coupled with modern bio-techs, formulation of the quality standards of new craft liquor as soon as possible and strict enterprise supervision to perfect enterprise quality guarantee system and to advance the development of new craft liquor and the improvement of liquor quality.

提高新工艺白酒质量的措施为：做好生产新工艺白酒基本原料如酒精、加浆水、食品添加剂、酒头、酒尾等的选用及处理；对新工艺白酒酒体进行科学设计，包括浓香型白酒中微量成分与己酸乙酯的关系、新工艺白酒的配方等；运用传统白酒生产工艺，结合应用现代先进的生物技术，尽快制订新工艺白酒质量标准，加大监管力度，完善企业质量保证体系，促进新工艺白酒的发展和质量提高。关键词：新工艺白酒；酒精；质量措施中图分类号： TS262.3；TS261.4 文献标识码： B 文章编号： 1001－9286（2007）02－0058－04
