[0002] Polygonatum odoratum is the rhizome of Polygonatum odoratum of the Liliaceae family. It tastes sweet and slightly cold. It enters the lung and stomach meridians. It has the effects of nourishing yin, moistening dryness, promoting body fluid and quenching thirst.

[0003] The effects and functions of Polygonatum odoratum are as follows:

[0004] 1. Nourishing yin and moistening dryness, it can prevent fever and relieve the damage of body fluid and dry throat and thirst caused by fever;

[0005] 2. Delay aging. The polysaccharides contained in Polygonatum odoratum can enhance the body's disease resistance and delay aging;

[0006] 3. Improve immunity. The antioxidant ingredients in Polygonatum odoratum can regulate human immunity;

[0007] 4. Cardiotonic effect;

[0008] 5. Prevent high blood pressure, promote blood circulation and accelerate myocardial contraction. Therefore, using Polygonatum odoratum to make soup has a certain health-preserving effect.

[0011] 2) The active ingredients in the product are not fully extracted and the nutritional value is not fully realized;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate the orientation or position relationship, or the orientation or position relationship in which the product of the invention is usually placed when used, only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] A method for producing a yuzhu original pulp beverage by enzymatic hydrolysis and extrusion, comprising the following steps:

[0040] Step 1: Pre-treatment of raw materials, crushing the raw materials into powder using a crusher;

[0041] Step 2: Mixing: Mix various powder raw materials in proportion and set aside;

[0042] Step 3: Extrusion: Add the powder and water at the same time, and extrude through an extruder;

[0043] Step 4: Enzymatic hydrolysis: add amylase and saccharifying enzyme and stir well;

[0044] Step 5: Grinding: Grind the enzymatic hydrolysis with a colloid mill;

[0045] Step 6: Centrifugal removal: The ground liquid is centrifuged to remove the residue and sediment;

[0046] Step 7: Homogenization: homogenize the centrifuged liquid;

[0047] Step 8: Pipeline sterilization: The homogenized liquid is subjected to pipeline sterilization.

[0048] Specifically: the method of producing odoratum puree beverage by enzymatic hydrolysis and extrusion not only simplifies the traditional production process, reduces energy consumption and improves production efficiency, but also realizes fine crushing in the raw material pretreatment stage, laying the foundation for subsequent uniform mixing and efficient extrusion. In the combined application of enzymatic hydrolysis and extrusion, the materials undergo complex physical and chemical changes under high temperature and high pressure conditions, which greatly promotes the decomposition and extraction of odoratum effective ingredients, thereby significantly improving the nutritional value of the beverage. Enzymatic hydrolysis technology can improve the effective ingredients of odoratum compared with traditional methods, so that the bioactive substances such as resveratrol and flavonoids required in the odoratum puree beverage can be more fully utilized, which not only improves the nutritional value of the product, but also provides scientific guarantee for the efficacy of the product.

[0049] Grinding by colloid mill ensures the fusion and uniformity of the various ingredients, saving additional processing steps in the subsequent filtration and modulation process. In the centrifugal deslagging stage, the coarse particles and residues that may be produced in the colloid mill process are removed, so that the purity of the feed liquid is significantly improved, which provides a guarantee for the accuracy and efficiency of subsequent homogenization and sterilization.

[0050] The application of pipeline sterilization technology effectively avoids the damage to ingredients that may be caused by traditional sterilization methods, protects the nutritional components and flavor characteristics of the beverage, and ensures that the final product has excellent color, aroma and taste.

[0051] The raw material involved in step 1 is Polygonatum odoratum

[0052] In step 3, the ratio between the solid powder and the added water is 1:2.

[0053] Specifically, the extruder squeezes the starch slurry from the feed end to the discharge end at a speed of 1 m / min. The pressure between the starch slurry and the extrusion screw reaches 120 MPa. This step extrudes the starch slurry so that the starch slurry is fully extruded and the fiber tissue in the raw material is squeezed out of the raw material.

[0054] In step 4, the amount of amylase added is 0.2% to 0.4%, the amount of saccharifying enzyme added is 0.3% to 0.5%, and the enzymolysis time is 30 to 45 minutes.

[0055] The grinding time in step 5 is 3 minutes.

[0056] In step six, the centrifugal deslagging operation is performed by using a horizontal centrifuge and a disc centrifuge, and the milled liquid is successively subjected to centrifugal deslagging treatment by using a horizontal centrifuge and a disc centrifuge.

[0057] Specifically: horizontal centrifuge and disc centrifuge are used to remove the dregs in the starch slurry. The horizontal centrifuge uses high-speed centrifugation technology to remove suspended impurities and large particles in the solution. After centrifugation, the starch slurry is clarified within 30 seconds to remove suspended solid impurities. The disc centrifuge uses ultra-high-speed centrifugation technology to remove tiny particle impurities with a particle size of less than 0.1um.

[0058] The homogenization pressure is between 30Mpa and 40Mpa.

[0059] The sterilization condition of pipeline sterilization is 120±0.5℃, the sterilization time is 60 seconds, and the material circulation is 10 minutes.

[0060] To sum up: the method of producing Polygonatum odoratum puree beverage by enzymatic hydrolysis and extrusion not only simplifies the traditional production process, reduces energy consumption and improves production efficiency, but also realizes fine crushing in the raw material pretreatment stage, laying the foundation for subsequent uniform mixing and efficient extrusion. In the combined application of enzymatic hydrolysis and extrusion, the materials undergo complex physical and chemical changes under high temperature and high pressure conditions, which greatly promotes the decomposition and extraction of Polygonatum odoratum's effective ingredients, thereby significantly improving the nutritional value of the beverage.
