Method for making yellow wine from recycled rice milk water

Abstract

The invention relates to a method for making yellow wine from recycled rice milk water. The method comprises the following steps: (1) weighing a certain amount of rice and soaking in proportion; and (2) taking rice milk water, heating till boiling, preserving heat, cooling to the room temperature, and adding the cooled rice milk water into yellow wine fermented mash in proportion, wherein the adding amounts of rice milk water are respectively 0.2%, 40% and 60%, the use of clean water is correspondingly reduced, the total water use amount remains unchanged, the total water addition amount in soaking and rice steaming processes is 3.5 times the amount of raw materials, the use amount of distiller's yeast is controlled at 10%, wheat koji is replaced by virtue of 2% of liquifying enzyme, saccharifying enzyme and protease, the primary fermentation temperature is 28 DEG C, the primary fermentation time is 7 days, the secondary fermentation temperature is 18 DEG C, and the secondary fermentation time is 14 days. According to the method, rice milk water is recycled to be used in the production process of the yellow wine and can be used for partially replacing feeding water under the conditions that the cost is not increased and the product quality is guaranteed, so that the cyclic utilization of rice milk water is realized, the treatment cost is lowered, and the energy-saving and cost-reducing purposes are achieved.

Description

technical field [0001] The invention relates to a method for brewing rice wine by recycling rice milk water, and belongs to the technical field of rice wine brewing. Background technique [0002] In the traditional rice wine brewing process, the glutinous rice needs to be soaked for a period of time, and the next rice steaming process can be carried out after the rice is loose. Therefore, the rice soaking process consumes a lot of water and produces high COD and total acid content. Rice milk water. And along with the expansion of yellow rice wine industry, the output of rice milk water also increases year by year. If the idea of ​​sewage treatment is still used to treat rice milk water, such as acidification, UASB anaerobic, SBR aerobic and other combined treatment processes, the treatment cost and equipment investment must be increased accordingly. In addition, rice milk is very rich in nutrients, including a large amount of organic acids, amino acids, proteins, starches,...

If the idea of ​​sewage treatment is still used to treat rice milk water, such as acidification, UASB anaerobic, SBR aerobic and other combined treatment processes, the treatment cost and equipment investment must be increased accordingly

In addition, rice milk is very rich in nutrients, including a large amount of organic acids, amino acids, proteins, starches, sugars, fats, vitamins, etc. If it cannot be used effectively, it will be a great waste
