Problems solved by technology

At present, tea saponin is usually extracted by water immersion method, and its disadvantage is that some water-soluble sugar and protein will also be extracted during the extraction process, thus affecting the quality of tea saponin
The other is the use of organic solvent leaching, the disadvantage of which is that the cost is high and the gain outweighs the gain

Embodiment Construction

[0016] Soak the tea seed meal in water (1Kg tea seed meal plus 10-20 liters of water) and soak for 1-2 days, then heat and boil, and keep stirring to fully dissolve the tea saponin in the water, filter while hot to remove the undissolved For impurities, wash the undissolved impurities with boiling water for 1-5 times, combine the solutions, add 50 grams of yeast according to the ratio, ferment at 25-32°C for 1-3 days with constant temperature and vibration, centrifuge, take the supernatant and add 3 times of ethanol to carry out Stir for 5 to 10 minutes, cool at low temperature, and then perform centrifugation, and concentrate the liquid with a rotary evaporator. 2 o 2 Carry out decolorization treatment, and then vacuum-dry to complete the product.

Abstract

The chemical process of extracting theasaponine from camellia seed oil cake includes the steps of: soaking camellia seed oil cake in 10-20 weight times water for 24-48 hr; heating to boil while stirring; filtering insoluble impurity and washing the impurity with boiled water for 1-5 times; vibrating yeast fermentation at 25-32 deg.c for 24-72 hr; centrifugal separation to eliminate impurity to obtain clear liquid; adding 3 times of ethanol to the clear liquid and stirring for 15 min; centrifugal separation after cooling; and concentration, decoloring and drying to obtain product.

Description

1. Technical field [0001] The invention relates to a method for extracting tea saponin from tea seed dregs by a chemical method, and belongs to the technical field of chemical purification of tea saponin. 2. Background technology [0002] Tea seed cake after oil extraction contains a certain amount of tea saponin. Although the content of tea saponin is higher due to different tea varieties, such as Qimen Muye, Lingui and Nanjiang, the content of other teas is different. Above 8%. In terms of pharmacology, tea saponin has many curative effects such as expectorant, anti-inflammatory, analgesic, cough and antibacterial. Tea saponin is a non-ionic surfactant, which is hardly affected by water hardness and has strong foaming power. Tea saponin also has moisturizing properties. It also has the characteristics of decontamination, emulsification and dispersion. Therefore, tea saponin is widely used in the manufacture of shampoo, paraffin emulsifier, concrete foam stabilizer and ...
