Preparation method of chrysanthemum morifolium extract

Abstract

The invention discloses a preparation method of chrysanthemum morifolium extract. The preparation method comprises the following steps of 1, crushing: crushing chrysanthemum morifolium as a raw material, 2, extraction: putting the crushed raw material into an extraction tank, carrying out extraction in twice, and treating the chrysanthemum morifolium by combined cellulase and pectase, 3, coarse filtration: carrying out filtration by a vibrating screen to remove impurities, 4, centrifugation: carrying out centrifugation by a disk centrifuge, 5, membrane condensation: carrying out condensation by a polyamide film, 6, sterilization: carrying out superhigh-temperature instantaneous sterilization, 7, blending: adding the condensed juice subjected to sterilization into a blending tank and adding maltodextrin into the condensed juice, and 8, spray drying: carrying out spray drying to obtain chrysanthemum morifolium extract. The chrysanthemum morifolium extract obtained by the preparation method has the characteristics of high total flavone content, high extraction ratio and good clarity. The preparation method can obviously improve adhesion to the tower in spray drying, and has the characteristics of simple operation, low price and no toxicity.

Description

technical field [0001] The invention relates to a preparation method of a chrysanthemum extract, specifically refers to a method for processing the chrysanthemum extract by using Hangbai chrysanthemum as a raw material, and belongs to the technical field of food and beverage processing. Background technique [0002] Chrysanthemum chrysanthemum, also known as chamomile, is a traditional cultivated medicinal plant in my country. It is one of the eight famous medicinal materials "Zhejiang Eight Flavors" in Zhejiang Province, and it is also the best variety in chrysanthemum tea. It has been proved by modern medical theory that it has the effects of stopping dysentery, reducing inflammation, improving eyesight, lowering blood pressure, lowering fat, and strengthening the body. It can be used to treat damp-heat jaundice, stomach pain, lack of food, edema and oliguria. Bathing with chrysanthemum soup has the functions of removing itching, refreshing the body, skin care and beauty....

AI Technical Summary

Problems solved by technology

After the Chrysanthemum chrysanthemum is treated with cellulase, the cellulose in the cell wall is hydrolyzed into water-soluble carbohydrates, and the hydrolysis of the cell wall is conducive to the dissolution of intracellular substances, so enzymatic extraction can improve the extraction rate of total flavonoids. The extraction methods of Chrysanthemum chrysanthemum reported in the literature mainly include: water decoction method, acid-base extraction method, ethanol reflux method, etc., using simple physical methods to extract Chrysanthemum chrysanthemum, but the above methods have low extraction yield, high cost and cause environmental pollution However, the use of new technologies such as ultrasonic and supercritical extraction has recently attracted widespread attention due to its high extraction efficiency, but due to problems such as excessive investment and cumbersome operations in production, the application of the above method in industrial production has been limited. Universal use

In addition, because the chrysanthemum extract contains a large amount of pectin, it is easy to cause blockage of the membrane pores during the membrane concentration process, affecting the concentration effect, and it is also easy to stick to the tower during the spray drying process, affecting the powder collection rate and flavor, resulting in unnecessary waste
