Environmentally friendly chemistry is the development trend of Baijiu production. However, there are still many problems that need to be addressed urgently in the current Baijiu production process. First, the production of Baijiu produces a large amount of brown water (Huangshui, HS), which may cause pollution to the environment. Second, the solid-state fermentation produces low amounts of alcohol. Combining with the practical experience of Baijiu production, we have proposed an environmentally friendly method of producing Baijiu. The results confirmed that rice husk with pretreatment of HS significantly reduced the hardness of rice husk, enhanced the elasticity of the skeleton structure of rice husk, and improved its efficiency as an auxiliary material for solid-state fermentation. Therefore, this method can not only effectively utilize HS, but also improve the efficiency of solid-state fermentation and reduce the amount of food consumption, which is in line with the development concept of green chemistry.

环保化学是白酒生产的发展趋势。但是，在当前的白酒生产过程中仍然有许多亟待解决的问题。首先，白酒的生产会产生大量的棕色水（黄水，HS），这可能对环境造成污染。第二，固态发酵产生少量的酒精。结合白酒生产的实践经验，我们提出了一种环保的白酒生产方法。结果证实，经过HS预处理的稻壳显着降低了稻壳的硬度，增强了稻壳骨架结构的弹性，并提高了其作为固态发酵辅助材料的效率。因此，这种方法不仅可以有效利用HS，
