Abstract

The invention discloses a production method of synchronously extracting tea-seed oil and tea saponin from tea seed cakes. The production method comprises the following steps: multi-stage impulse countercurrent extraction: feeding the tea seed cakes to an extractor and carrying out N-stage spraying and soaking extraction by using an extracting agent containing tea-seed oil and tea saponin to obtain a mixed solution and a mixed solid, wherein the mass fraction of the tea-seed oil in the extracting agent used in the Mth-stage spraying and soaking extraction is higher than that of tea-seed oil in the extracting agent used in the (M-1)th-stage spraying and soaking extraction, and M is greater than or equal to 2 but less than or equal to N; skimming and separating: filtering and skimming the mixed solution to obtain the first mixed solution containing tea-seed oil and a second mixed solution containing saponin; extracting the tea-seed oil: evaporating and steam-stripping the first mixed solution to obtain the tea-seed oil; extracting the saponin: evaporating, distilling and drying the second mixed solution to obtain tea saponin crude powder. The production method disclosed by the invention is suitable for industrial production on a large scale, solves the problem that the yield of tea saponin is low and the input of the extracting agent is great, and is energy-saving and consumption-reducing, and particularly free of environmental pollution.

Description

technical field [0001] The invention relates to the technical field of agricultural resource extraction, in particular to a production method for synchronously extracting tea seed oil and tea saponin from tea seed cakes. Background technique [0002] Tea seed (Camellioleifera) is a kind of oil-bearing crop unique to China, which is very rich in resources. The country can produce 600,000 tons of tea seed every year, and the annual output of tea seed cake after oil extraction is about 400,000 tons. It is 5-8%, and the content of tea saponin is 16-25%. [0003] The fatty acid composition of tea seed oil is similar to that of olive oil, the content of monounsaturated fatty acid-oleic acid is as high as 74-87%, and it also contains aliphatic vitamin E and squalene and other biologically active substances, which have obvious preventive heart disease. Arteriosclerosis, lowering blood pressure, lowering blood fat and other effects. [0004] Tea Saponin (TS), also known as tea sapo...
