Problems solved by technology

[0004] Polygonatum, as a medicinal and edible homologous raw material variety stipulated by the National Health and Family Planning Commission, has a certain effect on relieving diabetes. The small molecular sugar content of Polygonatum Polygonatum is mostly about 10%, and the Polygonatum Polygonatum small molecular sugar content produced in some places exceeds 20%. Because the small molecular sugar content in the Polygonatum Polygonatum of the prior art is high, it is not suitable for diabetics to eat

[0030] The Rhizoma Polygonatum Serum was sterilized at 121°C for 30min in an autoclave.

[0031] (3) Inoculation fermentation:

[0032] Cultured Lactobacillus plantarum CICC 24202 (Lactobacillus plantarum, LP for short), Lactobacillus brevis YM 1301 (Lactobacillus breris, LB for short);

[0033] The bacterial suspension was mixed at a volume ratio of 1:1 to prepare a starter, which was added to the Rhizoma Polygonatum Serum at an inoculum of 10%, and fermented at 36.5°C for 24 hours.

[0034] (4) Freeze drying:

[0035] The fermented product of Polygonatum is quickly frozen at -20°C, dried in a freeze dryer with a vacuum degree of 0.05-0.1 MPa for 24 hours, and then pulverized to obtain a freeze-dried pow...

Embodiment 2

[0039] (1) Raw material pretreatment:

[0040] Wash the fresh or dried sealwort, remove the moldy and moth-eaten parts, and crush it. The dry weight of sealwort: water is 1:10, add water to obtain the sealwort slurry, and adjust the pH to 6.2.

[0041] (2) Sterilization:

[0042] The Rhizoma Polygonatum Serum was sterilized at 121°C for 30min in an autoclave.

[0043] (3) Inoculation fermentation:

[0044] Mix the suspensions of LP strain and LB strain at a volume ratio of 1:1 to prepare a starter, add 10% of the inoculum into the Rhizoma Polygonatum Porridge, and ferment at 36.5°C for 24 hours.

[0045] (4) Freeze drying:

[0046] The fermented product of Polygonatum is quickly frozen at -20°C, dried in a freeze dryer with a vacuum degree of 0.05-0.1 MPa for 24 hours, and then pulverized to obtain a freeze-dried powder.

[0047] (5) Polygonatum fermented product freeze-dried powder is pretreated and mixed with other auxiliary materials. According to the conventional bever...

Embodiment 3

[0049] (1) Raw material pretreatment:

[0050] Wash the fresh or dried sealwort, remove the moldy and moth-eaten parts, and crush it. The dry weight of sealwort: water is 1:5, add water to obtain the sealwort slurry, and adjust the pH to 6.5.

[0051] (2) Sterilization:

[0052] The Rhizoma Polygonatum Serum was sterilized at 121°C for 30min in an autoclave.

[0053] (3) Inoculation fermentation:

[0054] Mix the suspensions of LP strain and LB strain at a volume ratio of 1:1 to prepare a starter, add 10% of the inoculum into the Rhizoma Polygonatum Porridge, and ferment at 36.5°C for 24 hours.

[0055] (4) Freeze drying:

[0056]The fermented product of Polygonatum is quickly frozen at -20°C, dried in a freeze dryer with a vacuum degree of 0.05-0.1 MPa for 24 hours, and then pulverized to obtain a freeze-dried powder.

[0057] (5) The freeze-dried powder of Polygonatum fermented product is mixed with food raw materials such as Polygonatum extract, licorice extract, flaxse...

Abstract

The invention discloses a Polygonatum fermented product, a preparation method and an application thereof, and belongs to the technical field of biomedicine manufacturing. The preparation method selects probiotic strains of lactic acid bacteria as a starter, inoculates the starter into the sterilized Rhizoma Polygonatum Serum and ferments to obtain Fermented Rhizoma Rhizoma Rhizoma Polygonatum; wherein the starter is composed of Lactobacillus plantarum and Lactobacillus brevis according to the ratio of bacterial suspension volume to 1 : 0-10 mixed, the starter is inserted into the sterilized Rhizoma Polygonati Serum by the inoculum of 1%-30%, and fermented at 20-36.5°C for 10-80h; the invention also discloses the above-mentioned Polygonatum fermented product And the application of above-mentioned Polygonatum fermented product. The preparation method of the present invention greatly reduces the small molecular sugars in Polygonatum, and ferments Polygonatum with lactic acid bacteria strains with high GABA production, which not only removes the small molecular sugars in Polygonatum, but also retains the saponins and polysaccharides in Polygonatum Active ingredients related to hypoglycemia; GABA and other ingredients produced by fermentation cooperate with active ingredients in Polygonatum to produce anti-type 2 diabetes effect.

Description

technical field [0001] The invention relates to the technical field of biomedicine manufacturing, in particular to a fermented sealwort, a preparation method and an application. Background technique [0002] Diabetes is one of the major diseases threatening human health. Diabetes is the third major disease that endangers human health after cardiovascular and cerebrovascular diseases and tumors. Its complications include hyperlipidemia, diabetic nephropathy, diabetic eye disease, liver damage, and cardiovascular diseases. The first-line drugs for the treatment of diabetes, such as sulfonylureas and biguanides, require long-term medication, and the drug costs are high. High-efficiency, low-toxic antidiabetic drugs or adjuvant therapy products are still a hot spot in the field of biomedicine. [0003] Traditional Chinese medicine has long-term clinical experience in the treatment of diabetes, and many drugs with significant curative effects have been discovered. Among them, ...
