Industrial production method for simultaneously extracting tea seed oil and tea saponin

Abstract

The invention discloses an industrial production method for simultaneously extracting tea seed oil and tea saponin. The industrial production method comprises the following steps: softening camellia seeds at a low temperature and separating shells and kernels to obtain camellia seed kernels; puffing the camellia seed kernels at a low temperature; extracting with an ether and alcohol homogeneous-phase mixing solvent to obtain homogeneous-phase mixing solvent extract; recycling the solvent from the homogeneous-phase mixing solvent extract; washing with water and separating by a centrifugal machine to obtain an alcohol phase and an ether phase; after recycling the solvent from the alcohol phase, separating the solvent by a foam separation tower and drying in vacuum to obtain the finished-product tea saponin; and after recycling the solvent from the ether phase, refining to obtain the tea seed oil, and adding alkali liquid to remove soap, de-coloring, deodorizing and winterizing in sequence to obtain the finished-product tea seed oil. According to the industrial production method, low-molecular-weight ether and low-molecular-weight alcohol can be mutually dissolved so that a homogeneous-phase mutually-soluble system is formed, and the tea seed oil and the tea saponin are effectively extracted; and meanwhile, tea seed meal with higher protein content also can be obtained, an application range of the camellia seeds is further expanded, the investment of extraction equipment is effectively reduced and the production cost is reduced.

Description

technical field [0001] The invention relates to an industrial production method for simultaneously extracting tea seed oil and tea saponin. 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 natural non-ionic surfactant with excellent performance. It also has hemolysis, insecticide, antibacterial and anti-inflammatory effects. [0003] At present, the extr...

Problems solved by technology

The industrial production of tea seed oil extracted from camellia oleifera is mainly produced by mechanical pressing and organic solvent extraction. The high temperature of the production process of mechanical pressing will destroy the main nutrients of tea seed oil and tea saponin. , and the prior art of organic solvent method all is the technological process of extracting tea saponin after extracting oil first to the processing technology of camellia oleifera seed, and its shortcoming is that the existence of the strong tea saponin of emulsifying ability can increase the extraction difficulty of tea seed oil, It affects the quality and yield of extracted tea seed oil, and then affects the quality and yield of tea saponin extraction in the later stage. At the same time, the production cycle is longer, which increases the production cost
