Problems solved by technology

The active ingredients of this compound are mainly polysaccharides. The polysaccharides are not dissolved completely when drinking tea, and the high temperature heating time is too long when boiling soup, which is not conducive to the effective utilization of active ingredients.

Embodiment 1

[0021] Weigh 1kg Pseudostellariae Radix, 1.5kg Radix Astragali and 2kg Jujube, add 10 liters of water and soak for 8 hours; drain the water and freeze at -18°C, keep the soaking water for subsequent extraction process; ) thawing; the raw materials after thawing were placed in a stainless steel grid tray, placed in a ventilated place at a temperature of 40°C to evaporate excess water, and the moisture content was measured to be 30.65% in 4 hours. Put the stainless steel mesh disk in the air explosion tank, raise the temperature inside the tank to 80°C, raise the pressure inside the tank to 0.1MPa higher than the atmospheric pressure outside the tank and keep it for 8 minutes, then drop the pressure inside the tank to a vacuum state for 30 minutes, and cool down to 40°C, release the vacuum, spray 4.5×10 to the material 5 U cellulase and 2.25 x 10 5 U pectinase (enzyme dissolved in distilled water, acetic acid to adjust the pH value to 5), keep warm at 40°C for 4 hours; after th...

Embodiment 2

[0024] Weigh 1 kg of Radix Pseudostellariae, 1.5 kg of Radix Astragali and 2 kg of Pitted Jujube, add 7 liters of water and soak for 24 hours, drain the water and freeze at -18°C for 6 hours, take it out at room temperature (18-25°C) and thaw; the thawed Pseudostellariae Put it into a stainless steel mesh pan, and blow off excess water at 60°C. After 4 hours, when the actual measured moisture is 27.13%, transfer the stainless steel mesh pan to an air explosion tank, raise the temperature inside the tank to 100°C, and The internal pressure rises to 0.3MPa higher than the atmospheric pressure outside the tank, and keeps for 3 minutes; then the pressure in the tank is instantly reduced to a vacuum state and kept for 30 minutes, then the vacuum is released, the temperature is lowered to 30°C, and 2.25×10 5 U cellulase and 9.0 x 10 4 U pectinase, insulated at 30°C for 10 hours, after the end of the heat preservation, the temperature in the tank was raised to 50°C, vacuumized until ...

Embodiment 3

[0026] Weigh heterophylla, astragalus, and jujube according to the formula, and perform gas explosion-enzyme revival treatment according to the method described in Example 1 or 2. Add 15 liters of water to the processed material, extract at 85°C for 40 minutes, filter, add 8 liters of water to the filter residue and continue to extract for 40 minutes, filter, and combine the filtrates. The filtrate was concentrated under reduced pressure until the specific gravity reached 1.1, and then freeze-dried to obtain instant powder of Radix Pseudostellaria Astragalus and Jujube.

[0027] The instant powder can be added with auxiliary materials, and the granules can be made according to the conventional method.

Abstract

The invention relates to a processing method for increasing the polysaccharide dissolution rate of a pseudostellaria heterophylla compound and a product thereof. The processing method comprises the following specific steps: taking pseudostellaria heterophylla rootlet or pseudostellaria heterophylla, astragalus membranaceus and a Chinese date, adding water for soaking, draining water, performing freeze-thaw treatment, then adjusting the mass fraction of water to 15-35%, then performing air blasting treatment to the treated medicinal materials, and then treating by using pectinase and celluloseto obtain the pseudostellaria heterophylla compound with high polysaccharide dissolution rate. The technological method is simple; after processing, the polysaccharide dissolution rate is high, and the polysaccharide dissolution rate reaches 80% in 10 minutes in hot water with the temperature of 95 DEG C; the pseudostellaria heterophylla compound can be used for developing a soup package or a teaproduct.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine processing, and relates to a processing method for improving the dissolution rate of polysaccharides of compound heterophylla, and also relates to a product prepared by the method. Background technique [0002] Pseudostellaria heterophylla (Miq.) Pax ex paxet Hoffm is a perennial herb of Pseudostellaria heterophylla (Miq.) Pax ex paxet Hoffm. Pseudostellaria heterophylla is sweet, flat and slightly bitter, and returns to the spleen and lung meridians. Invigorating qi and invigorating the spleen, promoting body fluid and nourishing the lungs, it has been confirmed by the Ministry of Health to be included in the "list of Chinese herbal medicines that can be used in health food". And Pseudostellariae Pseudostellariae is the fine branch root and tail whiskers left after collecting Pseudostellariae Pseudostellariae, which has similar pharmacological effects to Pseudostellariae Pseudostellari...
