Embodiment approach 1

[0028] The preparation method of the tea saponin that the present embodiment proposes comprises the following steps:

[0029] a. Break the tea seed meal, and vacuum extrude the crushed tea seed meal with a vacuum extrusion extruder (for example, the model is CY-32 improved type), the die hole of the vacuum extrusion extruder The hole diameter is 12-23mm, the screw speed is 60-170r / min, the sleeve temperature is 55-105°C, the vacuum degree is -0.03—-0.08Mpa, and the moisture content of tea seed meal is 11-19%. After the tea seed meal is dispersed, put it into a sealed bag, and let it dry in a refrigerator at 0-5°C.

[0030] b. Accurately weigh a certain amount of expanded tea seed meal and put it into a ball mill (for example, model MQ750×1060) for micronization by ball milling to form micronized powder. The parameters of ball milling micronization are: ball milling time 15- 80min, the ball milling speed is 115-200r / min, the filling rate of tea seed meal is 12-27%, the filling...

Embodiment approach 2

[0040] a. Carry out vacuum extrusion puffing with 20 mesh tea seed dregs with vacuum extrusion puffing machine, the aperture of the die hole of described vacuum extrusion puffing machine is 22mm, screw speed is 120r / min, sleeve temperature is 75 ℃, vacuum The temperature is -0.025Mpa, and the moisture content of the tea seed meal is 15%. After the expanded tea seed meal is dispersed, put it into a sealed bag, and let it stand and dry in a refrigerator at 0-5°C;

[0041] b. Accurately weigh a certain amount of expanded tea seed meal and put it into a ball mill for micronization by ball milling to form a micronized powder. The filling rate of the meal is 16%, the filling rate of the medium is 20%, and the micronized powder is sealed in a refrigerator at 2°C for standby;

[0042] c. Take the micronized powder in step b and mix it with cold water in a certain proportion at 2°C to obtain a mixed solution, control the temperature of the mixed solution at 2°C, and add 0.20% of the te...

Embodiment approach 3

[0046] The preparation method of the tea saponin that the present embodiment proposes comprises the following steps:

[0047] a. Carry out vacuum extrusion puffing with 35 mesh tea seed dregs with vacuum extrusion puffing machine, the aperture of the die hole of described vacuum extrusion puffing machine is 20mm, screw speed is 115r / min, sleeve temperature is 77 ℃, vacuum The temperature is -0.040Mpa, and the moisture content of the tea seed meal is 14.5%. After the expanded tea seed meal is dispersed, put it into a sealed bag, and let it dry in a refrigerator at 3°C;

[0048] b. Accurately weigh a certain amount of expanded tea seed meal and put it into a ball mill for micronization by ball milling to form a micronized powder. The filling rate of the meal is 18%, the filling rate of the medium is 21.5%, and the micronized powder is sealed in a refrigerator at 3°C ​​for standby;

[0049] c. Take the micronized powder in step b and mix it with cold water in a certain proportio...

Abstract

The invention discloses a method for preparing tea saponin. The method comprises the following steps: a, carrying out extruding-expansion treatment on a camellia oil cake; b, carrying out ball-milling micro-body treatment on the camellia oil cake; c, adding cold water and protease to extract residual tea-seed oil in the camellia oil cake; and d, adding hot water to adjust the ethanol-water ratio, so as to extract tea saponin. By adopting the method disclosed by the invention, the residual oil extraction rate of the camellia oil cake is 95-98%; compared with a common extraction method, the method disclosed by the invention has the advantages that the tea oil extraction rate is increased by 20-26%, the extraction rate of the tea saponin can be 47-55%, the tea saponin content is 76-85%,which is improved by 11-15%, compared with that of a general extraction method. Moreover, the residual oil extracted from the camellia oil cake which is subjected to extruding-expansion and micro-body treatment by adding cold water and an enzyme preparation is the tea-seed oil with excellent quality. Thus, not only is the added value of the camellia oil cake increased, but also the extraction time of the tea saponin is also greatly shortened, and consumption of a lot of energy sources is saved.

Description

technical field [0001] The invention relates to a preparation method of tea saponin, in particular to a method for applying vacuum extrusion expansion and miniaturization technology to the preparation of tea saponin. Background technique [0002] Camellia (camellia0leifera Ahel) is a unique woody oil plant in my country. It is mainly distributed in the mountains and hills of 14 provinces (regions) in southern my country. At present, there are about 4 million hectares of camellia forests in the country, and the annual output of camellia seeds exceeds 600,000 tons. . Camellia oil extracted from Camellia oleifera seeds has high nutritional value and health care function, and its fatty acid composition is similar to that of olive oil, so it is called "Oriental olive oil". Tea oil contains tea polyphenols and camellia glycosides, rich in VE, VD, VK, carotene and squalene. Long-term consumption can enhance the elasticity and toughness of blood vessels, delay atherosclerosis, incre...
