Embodiment 1

[0091] Example 1, take an appropriate amount of Yuzhu decoction pieces, crush them into granules of 0.1-0.3 cm, add 50-degree white wine at a feed ratio of 1:7.5, cold-soak overnight, and extract in countercurrent at a temperature of 50-70 °C (countercurrent circulation speed 1.0T / h *5kg) for about 6-8 hours, collect the extract, use it as extract-1, and set aside, add 50% white wine for the second time in the same way, and cold soak for 16-64 hours (Friday, Saturday, and Sunday are recommended for a total of 3 days) , countercurrent extraction during the day (countercurrent circulation speed 1.0T / h) for about 6-8h, collect the extract-2 and set aside. Combine the two extracts 1 and 2 as the stock solution, store it for later use, filter it with diatomaceous earth before use, and blend according to the established process.

Embodiment 2

[0093] Take appropriate amount of Yuzhu decoction slices, crush or cut into 0.6-1cm particles, flatten, or crush and then cut into 0.6-1cm particles, add 50% white wine at a ratio of 1:7.5, cold soaking temperature: site temperature 10 -35 degrees, heating countercurrent temperature: 50-70℃, countercurrent circulation speed 1.0T / h, cold soaking + countercurrent extraction time is 24-72 hours, "cold soaking - countercurrent - cold soaking - countercurrent" interval, cold soaking time : Heating countercurrent time = 2:1~8:1, collect the extract -1, set aside, add 50% white wine for the second time in the same way, "cold soaking - countercurrent - cold soaking - countercurrent" alternately extract, collect and extract Liquid-2, spare. Combine the 2 extractions, use it as a stock solution, store it for later use, filter it with diatomaceous earth before use, and blend according to the established process.

Embodiment 3

[0097] Take an appropriate amount of Yuzhu decoction pieces, break into small particles of 0.1-0.3cm, or cut into 0.6-1cm particles and flatten, or flatten and cut into 0.6-1cm particles, add 50% white wine respectively according to the ratio of 1:7.5, Cold soak overnight for 16 hours, extract at room temperature countercurrently for about 6-8 hours during the day, extract for 2 days, collect the extract-1, and set aside, add 50-degree white wine for the second time in the same way, and cold soak overnight (it is recommended to extend the time to 3 days, that is, , use Friday, Saturday, and Sunday to stand still), during the daytime, countercurrent extraction at room temperature for about 6-8 hours, collect the extraction solution-2, and set aside. Blend according to the established process (note that the volume of Polygonatum odoratum has doubled).

Abstract

The invention discloses a white spirit cold-soaking and countercurrent extraction method of polygonatum odoratum polysaccharide in a brewing technique and an online quality control method thereof. The extraction method comprises the steps of (1) slicing polygonatum odoratum or cutting the polygonatum odoratum into sections or grinding the polygonatum odoratum into granules; (2) cold-soaking the polygonatum odoratum in white spirit with alcohol concentration-volume ratio being 45-55% according to a charge rate of 1: (7.0-8.0) by mass; and (3) implementing countercurrent extraction by using white spirit of which the alcohol concentration-volume ratio is 45-55%. According to the optimized solution, the polygonatum odoratum is sliced or cut into sections or ground into granules and is pressed flat by external force. The method disclosed by the invention is direct and high in efficiency, overcomes difficulty in filtration, avoids contamination from moulds and can prevent polysaccharide which has relatively large molecular weight from precipitating in healthcare wine, thus being an ideal method for extracting polygonatum odoratum in the white spirit brewing technique. The solution of the control method does not need pre-treatment on a sample, comprises few analysis step and generates few error influence factors, consumes little time, and is capable of meeting demands of rapid determination and online quality control of samples in batches.

Description

technical field [0001] The invention relates to an extraction method, in particular to a liquor cold-soaking and countercurrent extraction method of Polygonatum polysaccharide in the wine-making process. The optimization scheme of the present invention also relates to the on-line quality control method in the process of cold soaking and countercurrent extraction of Polygonatum polysaccharide liquor in the brewing process. Background technique [0002] Polygonatum odoratum is the dry rhizome of Polygonatum odoratum (Mill.) Druce, a plant of the genus Polygonatum odoratum (Mill.) Druce in the family Liliaceae. [S]. Beijing: Chemical Industry Press, 2010]. Polygonatum odoratum is sweet, slightly cold. It has the functions of nourishing yin and moistening dryness, promoting body fluid and quenching thirst, and has activities such as lowering blood sugar, anti-tumor, and anti-oxidation. [0003] Polygonatum Polygonatum contains a large amount of polysaccharides, a small amount...
