Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a shampoo product containing wine lees water, its preparation method, and its application in the daily chemical field. Background Technology

[0002] Distillers' grains, or lees, are byproducts of the fermentation and distillation of cereal crops. They primarily originate from two sources: the brewing industry and the fuel ethanol industry. The composition of these two types of lees is related to their raw materials and processing techniques. The brewing industry often uses sorghum or a mixture of wheat, barley, corn, rice, rye, etc., adding yeast and saccharifying enzymes, and then processing them through cooking, saccharification, fermentation, and distillation to produce lees. Its components include incompletely fermented starch, protein, cellulose, organic acids, amino acids, vitamins, fats, flavor compounds, phenolic compounds, nitrogenous compounds, and heterocyclic compounds. The fuel ethanol industry primarily uses corn as a fermentation raw material. After dry grinding, water is added to produce a syrup, which is then liquefied and saccharified before yeast is added for fermentation to produce ethanol. After distilling the ethanol, the remaining lees are separated into wet lees and lees water. Distillery lees are mainly made from grains and other raw materials, fermented with yeast (mainly brewing yeast), and after collecting the liquor, the solid fermentation residue is discarded. The resulting distillation bottom water, cellar bottom water, and yellow water are extracted and filtered to obtain the fermentation product filtrate. Its main active components are amino acids, organic acids, sugars, small molecule peptides, nucleotides and their derivatives.

[0003] Fresh distiller's grains water is high in nutrients and acidity. If left untreated, it will spoil and deteriorate, severely polluting the environment and wasting resources. Comprehensive utilization of distiller's grains water will contribute to the sustainable development of liquor enterprises. Currently, research on the reuse of distiller's grains can be broadly divided into three categories: the first focuses on its application in animal feed, primarily concerning the impact of adding distiller's grains on animal growth, development, milk production, and milk quality; the second focuses on the ethanol fermentation of cellulose resources in distiller's grains, emphasizing pretreatment methods to improve the conversion of cellulose into fermentable sugars (a mixture of pentoses and hexoses, mainly xylose and glucose); and the third focuses on research into functional components with higher added value in distiller's grains water. Therefore, in-depth exploration of the impact of nutrients in distiller's grains water on reuse is not only important for broadening its application scope but also provides a reference for enhancing its added value and further comprehensive utilization.

[0004] Chinese patent CN117547498B discloses a wine lees skin-beautifying water, its preparation method, and its application. The method involves gradient alcohol precipitation of wine lees water with an ethanol solution to obtain an alcohol precipitate; filtering the precipitate to obtain a filtrate; adding an adsorbent to the filtrate for physical adsorption to obtain an adsorbate; using a series of resins to adsorb the adsorbate to obtain a resin adsorbate; and sterilizing the adsorbate at high temperature to obtain the wine lees skin-beautifying water. This wine lees skin-beautifying water exhibits excellent anti-inflammatory effects, significant anti-wrinkle and anti-aging effects, good oil control, significant improvement in skin moisture content, good safety, and excellent whitening effects.

[0005] Chinese patent application CN107988297A discloses a method for preparing small molecule peptides from fermented grains and their application in skincare products. The preparation method includes the following steps: S1: Fermented grains with a water content of 11%-22% are vacuum-extruded and expanded, cooled, pulverized, and sieved; S2: The expanded powder obtained in step S1 is subjected to alkali dissolution and acid precipitation to extract fermented grain protein, yielding a fermented grain protein extract; S3: The fermented grain protein extract obtained in step S2 is hydrolyzed with hydrolytic protease, the enzyme is inactivated, filtered, concentrated, frozen, and dried to obtain small molecule peptides from fermented grains. Applying these small molecule peptides from fermented grains to skincare products increases the added value of fermented grains while improving the moisturizing and repairing effects of the skincare products.

[0067] Table 4

[0068] (5) Measurement of conductivity and pH Although most macromolecular substances have been removed from the lees water after alcohol precipitation and physical adsorption, a significant amount of metal ions remain, resulting in high conductivity. This affects the viscosity of formulations (with thickening systems) and makes it unsuitable for preparing personal care products. Therefore, this invention employs tandem resin adsorption to reduce conductivity, successfully lowering it to an acceptable range. This test example measured the conductivity and pH of the lees water before and after tandem resin adsorption. The results are shown in Table 5, demonstrating a significant decrease in conductivity after tandem resin adsorption.

Before the test and on day 15 after use, volunteers rated their scalp itching, with a maximum score of 10 and a minimum score of 1. A higher score indicated a lower degree of itching. The scores of each volunteer were tallied, and the scalp itching improvement rate was calculated as follows: Scalp itching improvement rate = (average scalp itching score on day 15 - average scalp itching score before the test) / average scalp itching score before the test × 100%.
