Preparation method of functional cherry component

Abstract

The invention discloses a preparation method of a functional cherry component. The preparation method is characterized by comprising the following steps: (1) pretreating: decoring cherries, adding deionized water, and pulping twice; (2) performing pulp treatment: respectively adding mixed enzyme and a mixed inoculum into cherry pulp for enzymolyzing and fermenting; (3) extracting: adding absolute ethanol and a cherry leaf extract into a cherry fermentation solution, heating in a water bath and performing ultrasonic oscillation; (4) performing centrifugal filtration: washing filter residues, and performing membrane filtration on a filtrate by using a vacuum membrane; (5) performing freeze drying: performing low-temperature drying and freeze drying on the cherry membrane filtrate to obtain cherry extract powder. The extraction method of the functional cherry component has the characteristics of high extraction rate, high purity, high activity of the active component and the like; the functional pharmacological effect is significant; in addition, the preparation method is simple in operation and has the characteristics of safety, non-toxicity and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for preparing functional components of cherries. Background technique [0002] Cherry belongs to the genus Cherry, Rosaceae Rosaceae, Rosaceae. The cherry fruit has a pit, and the pulp is bright red, yellow or dark red, and the diameter of the fruit is about 10 mm. Cultivated and improved varieties of cherries are found in more than 40 countries in North America, Europe and Asia. my country's cherry varieties are mainly cherry varieties: Hongdeng, Hongmi, Hongyan, Zaohong, Pioneer, Dazi Labins, etc. The planting areas are mainly in Liaoning, Shaanxi, Henan, Jiangsu, Zhejiang and Sichuan provinces. Cherry fruit is nutritious and balanced, contains a lot of vitamins and minerals (K, Ca, Fe), its iron content ranks first among all fruits, and its sugar and fat content is low; and it is rich in anthocyanins, various Anthocyanins, melaton...

Problems solved by technology

However, in the extraction of active ingredients in traditional cherries, a large amount of organic reagents such as acetone are used. Although it can improve the extraction efficiency of functional ingredients in cherries, it is toxic and easy to remain. The extracted products have potential safety hazards, and the purification process is complicated and costly; However, using the water cooking extraction method, the extraction rate and the purity of the active ingredients are relatively low, and only the water-soluble functional components in the cherry can be extracted; while the pure centrifugal filtration method, there are tiny impurity particles in the filtrate, which affects the purity of the cherry extract components.
