Embodiment 1

[0026] A kind of preparation technology of rice-rinsing distiller's mother, comprises the steps:

[0027] ⑴ Rice soaking: The rice soaking water surface is 10 cm higher than the rice surface, and the rice soaking time is 36 hours. The soaked rice should be rinsed with clean water and drained.

[0028] ⑵ Steamed rice: The steamed rice is cooked but not mushy, the rice grains are soft, and there is no white heart inside.

[0029] (3) Sprinkle with water: first pour with cold water, then with warm water at 40°C until the product temperature is 29°C.

[0030] ⑷ Falling into the vat and building a nest: including mixing glutinous rice, Xiaoqu and purebred Xiaoqu thoroughly to form an inverted trumpet-shaped concave round nest. After the nest is finished, the product temperature is controlled at 27°C.

[0031] The pure-bred koji is made by mixing the pure-bred rhizopus bran koji and the pure-bred yeast bran koji. When mixing, the number of yeast cells is 400 million / g, and the we...

Embodiment 2

[0039] A kind of preparation technology of rice-rinsing distiller's mother, comprises the steps:

[0040] ⑴ Rice soaking: The rice soaking water surface is 10 cm higher than the rice surface, and the rice soaking time is 33 hours. The soaked rice should be rinsed with clean water and drained.

[0041] ⑵ Steamed rice: The steamed rice is cooked but not mushy, the rice grains are soft, and there is no white heart inside.

[0042] (3) Sprinkle with water: first pour with cold water, then with warm water at 39°C until the product temperature is 28°C.

[0043] ⑷ Falling into the vat and building a nest: including mixing glutinous rice, Xiaoqu and purebred Xiaoqu thoroughly to form an inverted trumpet-shaped concave round nest. After the nest is finished, the product temperature is controlled at 26°C.

[0044] The pure-bred koji is made by mixing the pure-bred rhizopus bran koji and the pure-bred yeast bran koji. When mixing, the number of yeast cells is 400 million / g, and the we...

Embodiment 3

[0053] A kind of preparation technology of rice-rinsing distiller's mother, comprises the steps:

[0054] ⑴ Rice soaking: The rice soaking water surface is 10 cm higher than the rice surface, and the rice soaking time is 42 days. The soaked rice should be rinsed with clean water and drained.

[0055] ⑵ Steamed rice: The steamed rice is cooked but not mushy, the rice grains are soft, and there is no white heart inside.

[0056] (3) Sprinkle with water: first pour with cold water, then with warm water at 42°C until the product temperature is 30°C.

[0057] ⑷ Falling into the vat and building a nest: including mixing glutinous rice, Xiaoqu and purebred Xiaoqu thoroughly to form an inverted trumpet-shaped concave round nest. After the nest is finished, the product temperature is controlled at 28°C.

[0058] The pure-bred koji is made by mixing the pure-bred rhizopus bran koji and the pure-bred yeast bran koji. When mixing, the number of yeast cells is 400 million / g, and the wei...

Abstract

The invention relates to preparation technology for a drenched rice wine yeast, belonging to the field of yellow wine brewing technology. The technology comprises the following steps: (1) rice soaking; (2) rice steaming; (3) water spraying; (4) cylinder feeding and nest building; (5) saccharifying, and water and koji adding; (6) primary fermenting; (7) secondary fermenting; and (8) maturing for further usage. The step (4) comprises that glutinous rice, small koji and pure small koji are fully blended to build a coved nest in an inverted trumpet shape, after which the product temperature of the nest is controlled at 25-28 DEG C. 150-180 g of small koji and pure small koji are added into every 100 kg of glutinous rice, wherein the weight ratio of small koji to pure small koji is 0.5-2:1. The purified small koji is prepared by mixing purified rhizopus bran koji with pure yeast bran koji, wherein yeast cell number is calculated as 400million / g in the mixing process, and the weight ratio of the pure rhizopus bran koji to the pure yeast bran koji is 100:5-7. The drenched rice wine yeast provided in the invention can greatly decrease the acetification rate of yellow wine in traditional processes.

Description

technical field [0001] The invention relates to a preparation process of glutinous rice wine, which belongs to the technical field of rice wine brewing. Background technique [0002] Linfan distiller's mother is a leavening agent produced by traditional crafts (big tank fermentation) Shaoxing rice wine and imitation Shaoxing wine. At present, Linfanjiumu is made from traditional naturally cultivated koji (wine medicine), and the quality is difficult to guarantee. Therefore, the rice wine brewed with Linfanjiu has the disadvantage of high rancidity rate. [0003] The preparation of Linfan Jiubo is essentially a process of enriching yeast. Traditional Xiaoqu is a saccharification starter produced by Linfan distiller's yeast. The functional microorganisms contained in it are Rhizopus saccharification and yeast as seeds. In addition, it also contains a certain amount of microorganisms such as bacteria that are harmful to fermentation. The pros and cons of fine yeast strains co...
