无酸发酵工艺克服了添加硫酸对设备、环境的危害，十多年来在糖蜜酒精行业多家酒精厂成功应用。随着糖蜜纯度变低，无酸发酵遭遇到细菌感染无法控制等问题，甘蔗糖蜜酒精厂陆续放弃无酸发酵工艺。糖蜜中含量不断增多的灰分、胶体等物质抑制酵母生长繁殖，酵母对细菌无法取得生长优势，导致无酸发酵工艺无法继续应用。在无酸或微酸条件下，尽可能多地排除糖蜜中灰分和胶体，才能从根本上解决无酸发酵染菌问题。
無痠髮酵工藝剋服瞭添加硫痠對設備、環境的危害，十多年來在糖蜜酒精行業多傢酒精廠成功應用。隨著糖蜜純度變低，無痠髮酵遭遇到細菌感染無法控製等問題，甘蔗糖蜜酒精廠陸續放棄無痠髮酵工藝。糖蜜中含量不斷增多的灰分、膠體等物質抑製酵母生長繁殖，酵母對細菌無法取得生長優勢，導緻無痠髮酵工藝無法繼續應用。在無痠或微痠條件下，儘可能多地排除糖蜜中灰分和膠體，纔能從根本上解決無痠髮酵染菌問題。

Acid-free fermentation process can overcome the damage of sulfuric acid to equipment and environment. It has been successfully used in some molasses alcohol plants in the past 10 years. Acid-free fermentation encounters problem of uncontrollable bacterial infection due to lower molasses purity and therefore molasses alcohol plants have to give up acid-free fermentation process. Increasing content of ash and colloid in molasses could inhibit the growth and breeding of yeast, and yeast is unable to obtain the growth advantage to bacteria, resulting in acid-free fermentation process unable to continue application. In acid-free or weak-acid conditions, only removing ash and colloid in molasses as much as possible can we fundamentally solve the problem of bacteria infection in free-acid fermentation.
