Problems solved by technology

The main problems are poor product quality, low purity, deep color, and a large amount of sugars and flavonoid glycosides, which greatly limit the further development and application of this type of product, especially in the process of refining stage, so far there has been no major breakthrough
However, the solvent extraction method needs to use a large amount of solvent, which increases the production cost, and sometimes there is a problem of solution residue. These unfavorable factors limit the further development and utilization of this product.

Embodiment 1

[0025] A preparation method of high-purity camellia oleifera saponin, the specific steps are as follows:

[0026] 1. Preparation of camellia oleifera cake powder: firstly crush the tea embryos that have been preliminarily screened to a mesh size of 10 mesh, and then send them to a decompression digital dryer for drying at a temperature of 35°C and a pressure of -40Pa. Then send it into the pulverizer for secondary pulverization, and pass through a 40-mesh sieve to obtain Camellia oleifera cake powder;

[0027] 2. Add 70% ethanol to the camellia oleifera cake powder, and adopt continuous countercurrent ultrasonic extraction. Under the action of ultrasonic waves of the ultrasonic device, the extraction time is once every 45 minutes, and the extraction time is 3 times in total. , separating the dregs and liquid to obtain medicinal dregs and an extract respectively;

[0028] 3. The medicinal residues are sent to the squeeze dryer and drying equipment in turn, and the solvent is d...

Abstract

The invention discloses a method for preparing high-purity oil tea saponins. In the method, oil tea cakes are used as a raw material, and by the organic combination of the technologies of continuous refluxing ultrasonic extraction, ceramic membrane micro-filtration, macroporous resin adsorptive separation (namely adsorptive purification) and also based on the traditional solvent refluxing extraction theory, the method solves the compatibility problem of working procedures such as extraction of oil tea saponins, solvent recovery and purification and meets the requirements of developing the high-purity oil tea saponins and deep-processing products of the high-purity oil tea saponins, and the concentration of the oil tea saponins is up to 85 to 95 percent; the environmental protection requirements are met in the production process, the product purity and yield are improved, the product quality is stabilized and the production cost is lowered. By adopting the medicinal residue drying and solvent recovering technologies, the solvent recovery rate is improved, the extraction cost is reduced and the safety production is realized. The method also has the advantages of high leaching efficiency, short time, low labor intensity, high productive capacity and the like.

Description

technical field [0001] The invention relates to a preparation method of medicine and food, in particular to a preparation method of high-purity camellia oleifera saponin. Background technique [0002] Camellia oleifera saponin is a mixture of pentacyclic triterpenoids extracted from camellia oleifera abel tree seeds by pressing or leaching. It is a non-ionic natural surface with excellent performance Active agent, and has many biological activities such as hemolytic, anti-osmosis, anti-inflammatory, phlegm-reducing, analgesic, anti-bacterial, anti-cancer, etc. It is widely used in building materials, daily chemicals, pesticides and food industries. my country has also developed many Products (such as tea saponin facial cleanser, liquid soap, auxiliary skin products, etc.). [0003] my country is a major producer and consumer of camellia oleifera saponin, with an annual sales volume of 200,000 tons, ranking first in the world. However, the per capita consumption level of tea ...
