specific Embodiment approach 1

[0006] Embodiment 1: In this embodiment, a method for preparing apple polyphenols is characterized in that the steps of the apple polyphenol extraction method are as follows: 1. Raw material pretreatment: select fresh apples, wash them, cut them into thin slices, and heat them at 100 ° C. Hot water, blanch for 30-60s to inactivate enzymes, quickly cool with cold water, dry in a vacuum oven at 35-40°C for 12-18 hours, pulverize, and store at low temperature for later use. 2. Separation and extraction of apple polyphenols: add apple powder and extractant at a ratio of 1g: 40mL to 1g: 60mL with a solid-liquid ratio, and use grinding beads to assist ultrasonic extraction for 40 to 60 minutes to obtain an extract containing apple polyphenols. Finally, use a decanter centrifuge to separate the solid and liquid at a speed of 1500 to 2000r / min, separate the extract and residue, add the residue to the extractant at a ratio of 1g: 40mL to 1g: 60mL, and continue Grinding beads assisted u...

specific Embodiment approach 2

[0007] Embodiment 2: This embodiment is different from Embodiment 1 in that in step 2, the extractant is an aqueous solution of acetone with a volume fraction of 70% to 90%, the diameter of the grinding beads is 3 to 4 mm, and the loading amount of the grinding beads is: Beads: Material 1g: 1g~1.25g: 1g, extraction time: 20~30 minutes, extraction temperature: 40~60°C, extraction power: 150~250W. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0008] Embodiment 3: This embodiment is different from Embodiment 1 in that it is characterized in that the concentration temperature in step 3 is 40-50° C., and the solid content in the concentrated solution is 60%-80%. Others are the same as in the first embodiment.

Abstract

The invention relates to a method for preparing apple polyphenol, which solves the problem that the prior method for preparing apple polyphenol is low in extraction efficiency, not high in purity and complex in production process. The method for preparing apple polyphenol comprises the technical steps of selecting apples, quickly slicing, rinsing and scalding the apples, removing enzyme, drying and grinding the obtained product, performing auxiliary ultrasonic extraction through grinding beads, using a centrifuge to separate extract liquid, using a rotary evaporator for concentration, performing purification and concentration through a chromatographic column and freeze-drying the obtained product through a vacuum freeze-drying machine to obtain apple polyphenol freeze-dried powder. The apple polyphenol prepared by the method is natural extract, is free from side effects on human bodies, and has the function of strengthening immunity, resisting tumor, reducing blood fat, lowering blood pressure, resisting blood coagulation and thrombosis, reducing weight, beautifying and protecting skin, and the like. The method can be applied to the fields of food, health-care products, cosmetics, medicine, biochemical engineering and the like.

Description

technical field [0001] The invention relates to a preparation method of apple polyphenols. Background technique [0002] Apple polyphenols are the main active factors in apples, which have the functions of enhancing immune function, anti-tumor, lowering blood fat, lowering blood pressure, anti-coagulation, anti-thrombosis, anti-caries, weight loss, beauty and skin care, etc. It can be used in food, health products, cosmetics, medicine, biochemical and other fields. It is a multifunctional product that is popular all over the world, and its market prospect is very broad. [0003] Polyphenolic compounds mainly exist in the central vacuole of plant cells; some phenolic compounds also exist in the cytoplasm, or in the wax on the plant surface and in the secreted leaves of buds. With the conventional solvent extraction method, it is not only a waste of time but also difficult to extract them all. At present, the extraction method of apple polyphenols is mainly based on ultraso...
