Abstract

The invention discloses a production method for extracting tea oil through an aqueous enzymatic method. Under proper pH, mixed enzyme is added, vibrating extraction is conducted in a glacial acetic acid-sodium chloride solution, osmotic pressure is formed by means of enzymolysis and a sodium chloride solution so that tea oil in tea seed kernels can be quickly released, then the tea oil is sterilized and dried, and the tea oil is obtained. The tea seed oil extraction yield is high, the content of microorganisms in the tea oil reaches the standard, no organic solvent residues exist, and the method is suitable for large-scale popularization.

Description

Technical field [0001] The invention relates to the field of edible oil processing, in particular to a production method for extracting camellia oil by an aqueous enzymatic method. Background technique [0002] Camellia oil is obtained from the seeds of the Camellia oleifera tree, also known as tea seed oil and camellia oil, which is a unique woody oil in my country. Camellia oleifera is rich in resources. Camellia oleifera forests account for more than 80% of the area of ​​woody edible oils. They are widely distributed in the hilly areas of 17 southern provinces, especially in Guangxi, Hunan, Jiangxi, Yunnan and other places. [0003] Tea oil contains a variety of functional ingredients, which have obvious effects on maintaining the function of the cardiovascular system, improving human immunity, lowering cholesterol, and preventing and treating high blood pressure. In addition, traditional medicine believes that tea oil has the effects of clearing away heat and dampness, killing...
