Embodiment 1

[0038] After cleaning the camellia seed, peeling off the shell, removing the seed coat, pulverizing and sieving through a sieve with an aperture of 100 mesh, to obtain the camellia seed kernel powder. The prepared Camellia oleifera seed kernel powder is added into hot water at 80°C with a water-to-material ratio of 5:1 (ml / g), and after being finished in a hot water tank, it is sent to a homogenizer for full homogenization to obtain a Camellia oleifera seed emulsion . After the camellia seed emulsion is cooled to 40°C, add 0.5% compound enzyme powder (composed of 20% pectinase, 30% amylase, 30% alkaline protease, and 20% cellulase) to adjust The pH of the enzymolysis solution is 9.0, and the enzymolysis is performed under mechanical stirring for 1.5 hours. The obtained enzymolysis product is coarsely filtered through a plate and frame filter, and the filter residue is used for later use. The coarse filtrate is finely filtered through a ceramic membrane with a microporous membr...

Embodiment 2

[0040] After cleaning the camellia seed, shelling it, removing the seed coat, pulverizing and sieving through a sieve with an aperture of 80 meshes, to obtain the camellia seed kernel powder. The prepared camellia seed kernel powder is added into hot water at 90°C with a water-to-material ratio of 4:1 (ml / g), and after being finished in a hot water tank, it is sent to a homogenizer to fully homogenize and finish, and the camellia seed emulsion is obtained. liquid. After the Camellia oleifera seed emulsion is cooled to 45°C, add 0.6% compound enzyme powder (composed of 15% pectinase, 35% amylase, 25% alkaline protease, and 25% cellulase) to adjust The pH of the enzymolysis solution is 10.0, and the enzymolysis is performed under mechanical stirring for 2 hours. The obtained enzymolysis product is coarsely filtered through a plate and frame filter, and the filter residue is used for later use. The combined filter residues are poured into an extraction cylinder equipped with an ...

Embodiment 3

[0042] After cleaning the camellia seed, peeling off the shell, removing the seed coat, pulverizing and sieving through a sieve with an aperture of 100 mesh, to obtain the camellia seed kernel powder. The prepared camellia seed kernel powder is added to hot water at 90°C with a water-to-material ratio of 6:1 (ml / g), and after it is finished in a hot water tank, it is sent to a homogenizer to fully homogenize and finish, and the camellia seed emulsion is obtained. liquid. After the camellia seed emulsion is cooled to 45°C, add compound enzyme powder (10% pectinase, 20% amylase, 20% alkaline protease, 30% glucanase, fiber 20% prime enzyme), adjust the pH of the enzymolysis reaction system to 10.0, and perform enzymolysis under mechanical stirring for 2 hours. The obtained enzymolysis product is coarsely filtered through a plate and frame filter, and the filter residue is used for later use. The crude filtrate is passed through a microporous membrane. Ceramic membrane fine filte...

Abstract

The invention discloses a method for sequentially extracting tea saponin and tea seed oil from oil-tea camellia seeds. A biological enzymatic hydrolysis method is firstly adopted for extracting tea saponin from shelled oil-tea camellia seed powder, and a water extraction method is further adopted for extracting the tea seed oil from desaponification residues. The process for extracting the tea saponin through the biological enzymatic hydrolysis method comprises the steps of cleaning, husking, crushing, fixing, homogenizing, performing enzymatic hydrolysis, performing coarse filtration through plate-frame filter cloth, and performing fine filtration through a miccroporous membrane. The process for extracting the tea seed oil through the water extraction method comprises the steps of ultrasonic vibration extraction and centrifugal separation. According to the method, the extraction efficiency of the tea saponin can be more than 90%, and the extraction efficiency of the tea seed oil can be more than 90%. The whole process flow is performed at low temperature, so that natural activity of the tea saponin, as well as vitamin E, phytosterol, squalene, natural flavor ingredients and the like in the tea seed oil are effectively protected. The foaming property and foam stability of the tea saponin prepared by the process are better in comparison with a traditional extraction method, the prepared tea seed oil has excellent quality, and the national pressed first-class tea seed oil standard can be achieved only by simple refining.

Description

technical field [0001] The invention relates to a method for sequentially extracting tea saponin and tea seed oil from camellia oleifera seeds, in particular to extracting tea saponin from camellia oleifera seeds by biological enzymolysis, and then extracting tea seed oil by water substitution Methods. Background technique [0002] Camellia oleifera is an evergreen, long-lived, high-oil-bearing woody economic oil plant unique to my country. It is also one of the four woody edible plant oil source tree species that are as famous as olives, oil palms, and coconuts. As we all know, camellia oleifera fruit (commonly called "camellia seed") contains about 30%-40% tea seed oil and about 10-15% tea saponin. Tea seed oil is a high-quality health-care edible vegetable oil. Its physical and chemical properties and fatty acid composition are very close to "vegetable oil queen" olive oil, so it is known as "Oriental olive oil". Tea saponin, also known as tea saponin, is a kind of natu...
