Embodiment 1

[0026] A kind of method utilizing yellow water to make bartender liquid, comprises the following steps:

[0027] (1) Add attapulgite to 3L of fresh yellow water, the addition of attapulgite is 0.5% of the fresh yellow water quality, then stir at room temperature for 6h, let stand to clarify and get the clear liquid, and obtain the first-level clear liquid 2.9 L;

[0028] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.3 MPa to obtain 2.88 L of the second-stage clear liquid;

[0029] (3) The second-stage supernatant was nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure was controlled to be 1.5 MPa to finally obtain 2.6 L of colorless and transparent liquor.

Embodiment 2

[0031] (1) Add attapulgite to 6L fresh yellow water, the addition amount of attapulgite is 0.6% of the fresh yellow water quality, then stir at room temperature for 6.5h, let stand to clarify and take the clear liquid, and obtain the first-level clear liquid 5.8L;

[0032] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.2 MPa to obtain 5.73 L of the second-stage clear liquid;

[0033] (3) The second-stage clear liquid is nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure is controlled at 1.0 MPa to obtain 5.3 L of colorless and transparent liquor.

Embodiment 3

[0035] A kind of method utilizing yellow water to make bartender liquid, comprises the following steps:

[0036] (1) Add attapulgite to 9L of fresh yellow water, the addition of attapulgite is 0.8% of the fresh yellow water quality, then stir at normal temperature for 8h, let stand to clarify and get the clear liquid, obtain the first-level clear liquid 8.5 L;

[0037] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.5 MPa to obtain 8.32 L of the second-stage clear liquid;

[0038] (3) The second-stage supernatant was nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure was controlled to be 2.0 MPa, and finally 7.6 L of colorless and transparent liquor was obtained.

[0039] The fresh yellow water in Embodiment 1 to Embodiment 3 is taken from the production workshop of Luzhou Laojiao Co., Ltd. Compared with the yell...

Abstract

The invention belongs to the field of preparation of daqu liquor, and in particular relates to a method for preparing blending liquid by utilizing yellow water, and an application of the blending liquid. The method comprises the following steps: adding a suitable amount of attapulgite into fresh yellow water, stirring under room temperature for 4-8 h, standing, clarifying, centrifuging, intercepting filter residues, and taking the clear liquid, thus obtaining first-grade clear liquid; carrying out microfiltration on the first-grade clear liquid by adopting a 0.2 Mu m inorganic ceramic membrane for removing the residual attapulgite particles, intercepting filter residues, and taking the clear liquid, thus obtaining second-grade clear liquid; and carrying out nanofiltration on the second-grade clear liquid by adopting an organic membrane with the molecular cut off being 300, intercepting filter residues, and taking the clear liquid, and thus obtaining the colorless and transparent blending liquid. The method is simple, convenient and effectively; the attapulgite is mainly used for absorbing macromolecular impurities, the colloid property of yellow water is destroyed, the viscosity is reduced, the blockage for the membrane during the follow-up membrane filtration processes is alleviated, the clarified yellow water is rapidly decolored and concentrated by utilizing the microfiltration using the inorganic ceramic membrane and the nanofiltration using the organic membrane, and finally the colorless and transparent blending liquid with special flavor is obtained.

Description

technical field [0001] The invention belongs to the field of Daqu wine production, and specifically relates to a method for making liquor by using yellow water and an application thereof. Background technique [0002] Yellow water is the main by-product in the brewing process of liquor, accounting for 30% of liquor production. Yellow water contains 1%-2% residual starch, 0.3-0.7% residual sugar, 4%-5% alcohol, and contains long-term domesticated Beneficial to microorganisms; at the same time, rich in alcohols, esters, acids, aldehydes and other aroma and taste substances, sugar substances, fluorine-containing compounds, and a small amount of tannins and pigments. Every 10,000 tons of Daqu liquor produces 3000-4000 tons of yellow water. The composition of yellow water is very complex. It has been determined that it contains a large number of aroma and taste substances such as alcohols, aldehydes, acids, and esters, some of which are similar to those in wine. Rich in organic...
