Abstract

The invention discloses a method for preparing tea saponin under the coupled action of a high-voltage pulsed electric field and biological enzymatic hydrolysis. The method comprises the following steps: subjecting degreased tea seed meal powder to homogenization, then feeding the homogenized tea seed meal powder into a high-voltage pulsed electric field treatment chamber for treatment, and carrying out enzymatic hydrolysis so as to obtain a crude extract of tea saponin; and subjecting the crude extract of tea saponin to flocculation, then to microfiltration for removal of impurities and then to nanofiltration, concentration and purification so as to obtain the tea saponin. The method of the invention carries out deep processing and comprehensive utilization on tea seed meal, a by-product of processing in the tea seed oil industry in China, and the prepared tea saponin can be used as a natural non-ionic surfactant and is widely applied to daily chemicals, medicine, food, pesticides andother industries. The method of the invention is simple in operation process, low in cost and applicable to industrial production of various scales, and effectively solves the problem of discharge ofwaste produced in tea seed oil production and processing.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural and sideline products, and in particular relates to a method for preparing tea saponin through high-voltage pulsed electric field coupling biological enzymolysis. Background technique [0002] Camellia oleifera, also known as tea seed tree, tea oil tree, etc., is mostly distributed in the southern region. The output of camellia oleifera seeds in my country is 1 million tons per year. Camellia oleifera seeds can be pressed to obtain high-quality edible oil. The oleic acid content of camellia oleifera oil can be as high as 86%, and the linoleic acid content is 7-10%, which can be compared with olive oil. The output of camellia seed meal, which is the residue after oil extraction from camellia oleifera, is about 690,000 tons per year, and it shows an increasing trend every year. Tea seed meal is rich in nutrients, such as: about 20% tea saponin, 5-6% residual oil, 12-16% prot...
