The folk traditional method for promoting the production and fermentation of distiller's yeast by using polygonum hydropiper comprises the following steps: the addition of the polygonum hydropiper in the distiller's yeast can enhance the unique flavor of the rice wine, prevent rancidity and peculiar smell, promote the growth and reproduction activities of adopted zymophyte, improve the quality of the distiller's yeast and prolong the quality guarantee period of the rice wine. However, the polygonum hydropiper used in the traditional process contains anthraquinone, and the anthraquinone belongs to one of 2B carcinogen lists which are preliminarily collated and referred to by carcinogen lists published by international cancer research institutes of world health organization. Therefore, the invention aims to provide a process technology capable of reducing the content of anthraquinone in the polygonum hydropiper extract; furthermore, the reduction of anthraquinone can provide a better fermentation environment condition for the zymophyte, thereby producing the health rice wine with better quality.
The 6-amino nicotinic acid contains carboxyl and amino with stronger polarity, and the two groups have specific relative positions so as to have a specific electronegativity center; the relative position and spatial configuration of carbonyl and silicon in bis (trimethylsilyl) carbonyldiimine enable the bis (trimethylsilyl) carbonyldiimine to have polarity within a specific range, the combination of the two is used as a synergist to promote the long-chain structure of linoleic acid to be cross-linked with glucan molecules in a spiral winding manner, the spatial entanglement complexity of glucan is further improved, the number ratio of introduced carboxyl, amino, carbonyl and silicon can form specific electronegativity strength, the adsorption effect on anthraquinone in polygonum hydropiper concentrated solution is enhanced, and the residual amount of anthraquinone in the prepared polygonum hydropiper extract is reduced. When the modified glucan prepared by the invention is used for chromatography of the polygonum flaccidum concentrated solution, functional groups such as silicon groups and amino groups are connected to the surface of the modified glucan, so that the passing rates of various natural antioxidant components such as alpha-limonene, beta-caryophyllene, 1-phenanthrene, zingiberene, alpha-pinene, bergamotene, isorhamnetin, kaempferol humulene, gamma-terpinene, bisabolene, hyperoside, rutin and quercetin can be increased while anthraquinone is adsorbed, the loss of white in chromatography operation of the beneficial components is avoided, and the capacity of the polygonum flaccidum extract liquid for removing free radicals is enhanced. When the modified glucan prepared by the invention is used for preparing the polygonum flaccidum extraction liquid, the residual amount of anthraquinone can be effectively reduced, and the anthraquinone is harmful to human bodies and can also have adverse effects on strains used for distiller's yeast fermentation, such as slow growth and toxic substances generated by microorganisms in a stress state; therefore, when the modified glucan prepared by the invention is used for preparing the polygonum flaccidum extraction liquid, the distiller's yeast fermentation strain can obtain a better living environment, so that more fusel with unique flavor and derivative esters thereof are fermented, and the unique smell and flavor are provided for the finally prepared health-care rice wine.

The DPPH free radical clearance rate of the embodiment 1 is higher than that of the embodiments 2-3 and the comparative examples 1-4, because the modified glucan prepared by the invention can increase the passing rate of various natural antioxidant components such as alpha-limonene, beta-caryophyllene, 1-phenanthrene, zingiberene, alpha-pinene, bergamotene, isorhamnetin, kaempferol humulene, gamma-terpinene, bisabolene, hyperoside, rutin and quercetin while adsorbing anthraquinone due to the fact that functional groups such as silicon groups and amino groups are grafted on the surface of the modified glucan when the modified glucan is used for chromatography of the polygonum hydropiper concentrated solution, the white loss of the beneficial components in chromatography operation is avoided, and the capacity of the finally obtained polygonum hydropiper extract for scavenging free radicals is enhanced.

The odor score and the taste score of example 1 are obviously better than those of examples 2-3 and comparative examples 1-6, because the modified glucan prepared by the invention can effectively reduce the residual amount of anthraquinone when being used for preparing the polygonum flaccidum extract, and anthraquinone is harmful to human bodies and can also have adverse effects on strains used for distiller's yeast fermentation, such as slow growth and toxic substances generated by microorganisms under a stress state; therefore, when the modified glucan prepared by the invention is used for preparing the polygonum flaccidum extraction liquid, the distiller's yeast fermentation strain can obtain a better living environment, so that more fusel with unique flavor and derivative esters thereof are fermented, and the unique smell and flavor are provided for the finally prepared health-care rice wine.
Test example 4
And (3) testing the insomnia relieving capacity: 160 subjects suffering from long-term insomnia, with the ages of 25-45 years and half of men and women are selected and divided into 4 groups of 40 persons, wherein one group serves as a control group; the control group did not eat the health rice wine obtained in examples 1-3 of the present invention and used 100mL of distilled water as a blank control, after drinking 100mL of the health rice wine 1h before sleeping every day; the test period is 28 days, the number of insomnia people per day in the test period is counted, the insomnia relieving capacity is measured by the sleeping time of each night, and the longer the sleeping time is, the more serious the insomnia is. The time to sleep of each subject was averaged over each group as the time to sleep data for that group. The test results are shown in table 4.
