摘要
酒糟窖底水也称黄水或黄浆水,是酱香型白酒的酿造副产物.酒糟窖底水中有机成分、微生物资源丰富,具有低pH、高化学需氧量(COD)和生化需氧量(BOD)等特点,直接排放极易造成资源浪费和污染环境.近年来,提高窖底水中有机物质利用率、增加其附加值成为研究热点.目前,关于窖底水的研究仅集中于浓香型和清香型白酒,而酱香型白酒酒糟窖底水综合利用的相关研究报道较少或者利用利率不高.该文对酒糟窖底水理化及微生物特点进行概述,浅析窖底水综合利用情况,并总结窖底水处理方法,旨在为窖底水资源的合理利用提供理论依据,在减少环境污染和企业酿造副产物处理成本方面具有一定参考价值.
Abstract
Pit bottom water of distiller's grains,also known as Huangshui or Huangjiangshui,is a by-product of the brewing of sauce-flavor(Jiangxi-angxing)Baijiu.The pit bottom water of distiller's grains is rich in organic components and microbial resources,and has the characteristics of low pH,high chemical oxygen demand(COD)and biochemical oxygen demand(BOD).Direct discharge is easy to waste resources and pollute the environment.In recent years,improving the utilization rate of organic matter in pit bottom water and increasing its added value have become research hotspots.At present,the research on pit bottom water only focuses on strong-flavor(Nongxiangxing)and light-flavor(Qingxiangxing)Baijiu,while there are few research reports on the comprehensive utilization of pit bottom water of sauce-flavor Baijiu distiller's grains or the utilization rate is not high.In this paper,the physicochemical and microbial characteristics of pit bottom water of distiller's grains were summarized,the comprehensive utilization of pit bottom water was analyzed,and the treatment methods of pit bottom water were summarized,aiming to provide a theoretical basis for the rational uti-lization of pit bottom water resources,and have certain reference value in reducing environmental pollution and the cost of treatment of brewing by-products.
