Production technology of Mucuna Pruriens extract products

Abstract

The invention discloses a production technology of Mucuna Pruriens extract products, and belongs to the technical field of advanced processing of Mucuna Pruriens. The technology comprises the following steps: processing Mucuna Pruriens to obtain Mucuna Pruriens powder; adding vitamin B3 and citric acid into water to achieve dissolving, adding the Mucuna Pruriens powder, performing uniform mixing,carrying out ultrasonic extraction, then carrying out refluxing extraction, adjusting the pH value of the obtained solution to 4.5-5.5, standing the obtained solution for precipitation to obtain an extract liquid, centrifuging the extract liquid, and drying the obtained precipitate and mother liquor to obtain Mucuna Pruriens extract I; and concentrating the above obtained supernatant to obtain a crude product, and refining, drying, crushing, mixing and packaging the crude product to obtain Mucuna Pruriens extract II. The technology has the advantages of less flow, no pollutant emission, high yield and high purity of the Mucuna Pruriens extract products, small consumption of an extractant, and easiness in industrial production. The cost of the technology is far lower than that of traditional technologies, and is close to the blending cost of low-content dihydroxyphenylalanine. A series of products containing 10-99% of the Mucuna Pruriens extract products can be produced through the technology, so the technology can meet demands of different clients, and ensures the sales quality of the products.

Description

technical field [0001] The invention belongs to the technical field of quinoa bean deep processing, and in particular relates to a production process of a quinoa bean extract. Background technique [0002] Quinoa bean is the dry seed of the plant of the genus Quinoa chinensis. It is mainly produced in Guangxi, Guizhou and other regions of my country. At present, quinoa bean is widely used in medicine to treat Parkinson's disease, poisonous snake bites, male infertility and other diseases. Levodopa is the main active ingredient. Levodopa is one of the precursors for the synthesis of norepinephrine and dopamine in the body, which can increase the level of dopamine in the brain tissue. It is an important biologically active substance in the body. important intermediates in biochemical metabolic pathways. At present, levodopa products are made by blending high-content levodopa and starch in a certain proportion (so called blended dopa). Although the cost is low, its pharmacolog...

Problems solved by technology

The more prominent problem of the acid water-resin method is that the extraction process consumes a large amount of hydrochloric acid, which requires particularly high acid resistance of the equipment, resulting in short service life of the equipment, quick update, and high production costs; another obvious disadvantage of the acid water-resin method is : The production process produces a large amount of acidic wastewater, and after neutralization, a large amount of protein precipitates are precipitated. The COD is as high as 10,000 mg / L, which seriously exceeds the national discharge standard of COD less than 100 mg / L. Therefore, this type of sewage treatment facility requires large investment and environmental protection. The cost is extremely high, the pressure on environmental protection increases, and the product cost is high

The disadvantage is that after the particles and colloidal ions in the extract are adsorbed and deposited on the membrane surface or in the membrane pores to a certain extent, the membrane pores are quickly blocked and become smaller, and the permeation flow and separation characteristics of the membrane are irreversibly changed. Phenomenon, the membrane permeability and transmittance are almost 0, and the membrane needs to be regenerated frequently, so that the service life of the filter membrane is very short, and the filter membrane needs to be updated frequently, and the cost is very high

But this method has the following disadvantages: the pH adjusted by the extract is 5.5-8, and finally there will be about 5% of acid-base wastewater to be discharged, and more components such as ammonium bicarbonate, ammonium sulfate, and tannin are added in the extraction process Acid, sodium metabisulfite, etc., increase the cost and cause some pollution to the environment; cat beans are extracted after being flattened, and cannot obtain levodopa to a greater extent, and the product yield is only 3-3.5%, which needs to be improved

[0006] At present, the processing and production of levodopa by quinoa beans generally has defects such as complicated procedures, low extraction rate, low purity of levodopa, and high cost.

Due to the particularity of the extraction of lentil beans, the current production cost of levodopa from quinoa beans remains high and cannot compete with low-content levodopa that is chemically synthesized or blended with high-content levodopa and starch. The pharmacological effect of the extract is obviously better than blended dopa, but because of its extremely high price, it affects sales and cannot fully open up the market
