[0002] As people pay more and more attention to health and wellness, they are becoming more and more fond of various plant drinks. Plant drinks are usually made from the roots, stems, leaves, flowers, and seeds of plants, and are processed by extracting their main ingredients. Their main functions include supplementing nutrition, anti-oxidation, anti-aging, promoting digestion, regulating metabolism, enhancing immunity, improving organ function, and beautifying the body, etc. Processing various plants rich in nutrients or functional ingredients (especially herbal plants) into drinks is not only convenient to eat, but also easier to be absorbed by the human body, and can achieve better health care effects. Therefore, such plant drinks are becoming more and more popular among people, and the market prospects are broad. At present, there are indeed more and more such plant drinks on the market, and many beverage manufacturers are also actively investing in the development of such plant drinks.

[0003] The main difficulty in producing this type of plant beverage lies in the extraction of the main components of the plant. In the process of extracting the main components of the plant, the first consideration is the extraction rate, and the second consideration is to minimize the damage to the effective components of the extract. The current plant beverage production process is still in the process of overcoming these technical problems. Although great progress has been made, the overall process level is still at a low level and urgently needs further improvement and improvement. Summary of the invention

DETAILED DESCRIPTION

[0007] A production process of a plant beverage comprises the following processing steps: a. Pretreatment: Each plant raw material is subjected to immersion cleaning, impurity removal and shredding respectively; immersion cleaning can clean the plant raw materials more cleanly and comprehensively without leaving any dead corners, and almost completely remove various residues on the surface of the plant and impurities mixed in the raw materials; b. Drying treatment: Each plant raw material after pretreatment is subjected to low-temperature drying treatment, and the drying temperature is controlled below 40°C; the drying treatment can remove most of the moisture remaining on the surface of the plant raw materials, so that the raw materials can be kept dry and clean, and are convenient for subsequent enzymatic hydrolysis and extraction treatment; c. Enzymatic extraction treatment: Place the dried plant raw materials in containers respectively, add an appropriate amount of extraction solvent to mix, and add an appropriate amount of cellulase, hemicellulase and pectinase to perform enzymatic reaction. The enzymatic treatment time is 30 minutes to 60 minutes to obtain enzymatic solution of each plant raw material; cellulase, hemicellulase and pectinase can effectively decompose plant cell walls, thereby helping to release the effective components in the cells and improve the clarity of the liquid; moreover, cellulase itself also has the functions and effects of promoting digestion and absorption, promoting the balance of intestinal flora, improving the function of the digestive system, regulating immune response, and reducing inflammatory response, which is beneficial to human health; d. High-pressure extraction treatment: The obtained enzymatic hydrolysates of each plant raw material are transferred to the high-pressure extraction equipment respectively, and the crude extracts of each plant raw material with high extraction rate are obtained through pressure-boosting, pressure-maintaining and pressure-releasing operations; in the pressure-boosting stage, the pressure is rapidly increased from normal pressure to several hundred MPa within a few minutes, and an ultra-high pressure difference is formed inside and outside the solid tissue cells. The extraction solvent rapidly penetrates into the vascular bundles and glandular cells inside the plant under the promotion of ultra-high pressure. As the pressure rises rapidly, the cell volume is compressed. If it exceeds its deformation limit, it will cause the cell to rupture, and the substances in the cell will contact with the solvent and be dissolved; if it does not exceed the deformation limit of the cell, the extraction solvent enters the plant cell under the action of high pressure, and the effective ingredients are dissolved in the extraction solvent; pressure-maintaining stage: ultra-high pressure causes the volume change of the system, which promotes the movement of chemical equilibrium, and the penetration of the solvent and the dissolution of the solute quickly reach equilibrium. Therefore, the pressure-maintaining stage is very short and can generally be completed within a few minutes; pressure-releasing stage: pressure-releasing is generally completed within two or three seconds, and the pressure of the tissue cells is rapidly reduced from the ultra-high pressure of several hundred MPa to normal pressure, Under the action of reverse pressure, the volume of fluid and drug matrix explodes and expands, forming a strong impact on the cell wall, cell membrane, plasma membrane, nuclear membrane, vacuole, microtubule, etc., causing deformation. If the deformation exceeds its deformation limit, the cell structure will become loose, with holes, ruptures and other structural changes. The active ingredient and the solvent are in full contact, and the solution dissolved with the active ingredient will diffuse rapidly outside the cell. If the deformation of the cell wall under the action of reverse pressure does not exceed its deformation limit (permeability increases under high pressure), the solvent that has dissolved the active ingredient inside the cell will quickly transfer to the outside of the cell under the high osmotic pressure difference, achieving the purpose of extraction. e. Ultrasonic extraction treatment: The crude extracts of each plant raw material obtained above are subjected to ultrasonic treatment, with an ultrasonic power of 200W to 300W, an ultrasonic frequency of 20kHz to 40kHz, and a treatment time of 15min to 20min to obtain crude extracts of each plant raw material with a higher extraction rate; the cavitation effect, mechanical effect, and thermal effect of ultrasound are used to accelerate the release, diffusion, and dissolution of effective substances in plant cells, thereby improving the extraction rate.

[0008] f. Centrifugal separation: The crude extracts of each plant material obtained in step e were centrifuged (using a centrifuge), and after precipitation, the supernatant was taken as a refined extract; g. Purification: Use gel column chromatography and / or ultrafiltration to purify the extracts obtained in step f to remove impurity proteins and small molecule impurities to obtain high-purity plant raw material extracts; gel column chromatography is a commonly used separation (filtration) method with simple equipment and convenient operation. It is particularly suitable for separating and purifying biological molecules such as proteins, nucleic acids and polysaccharides. In the treatment of plant extracts, gel column chromatography can effectively remove impurities, purify effective ingredients, and does not change the biological activity of the components; ultrafiltration is a membrane separation technology that uses pressure difference for separation. It is suitable for the separation and concentration of macromolecular substances. In the treatment of plant extracts, ultrafiltration can effectively desalt, remove small molecule impurities and concentrate effective ingredients. It is simple to operate and can maintain the biological activity of the components.

[0009] h. Concentration treatment: The obtained plant raw material extracts are concentrated by vacuum concentration or reverse osmosis concentration to obtain concentrated plant raw material extracts. Compared with the traditional evaporation concentration method, the reverse osmosis concentration method can better retain the original aroma of the plant raw materials and has minimal damage to the heat-sensitive components in the extract, thus retaining the original flavor and nutrients of the plant raw materials as much as possible.

[0010] i. Preparation and homogenization: Various raw materials including concentrated extracts of various plant raw materials are added to the running mixing and stirring equipment according to the established feeding order and feeding ratio, and the finished plant beverage is obtained after homogenization treatment by the mixing and stirring equipment; j. Sterilization and filling: Use UHT sterilization (ultra-high temperature instantaneous sterilization) equipment or pasteurization to sterilize the finished plant beverage, and use filling equipment to bottle / bag the sterilized finished plant beverage.

[0011] The above implementation modes are only used to explain the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes made on the basis of the essential scheme of the present invention shall fall within the protection scope of the present invention.
