Refined extraction method of tea seed oil rich in selenium and vitamin E

Abstract

The invention discloses a refined extraction method of tea seed oil rich in selenium and vitamin E. The method overcomes the deficiencies in the prior extraction method of tea seed oil, such as high temperature, fast and uneven heating, large influences on nutrition quality of tea seed oil, low purity, etc. The method comprises the following steps: twice rotary baking is carried out for tea seeds with shells removed and tea seeds with inner shells removed respectively; inner peels which cling to the tea seed pulp are removed; tea seed oil is obtained by a native extraction method, and centrifugation is carried out for removing slags and purifying. The method is used for extracting the tea seed oil, and is especially suitable for refined extraction of tea seed oil rich in selenium and vitamin E; the method can prevent damage and loss of nutrients in the tea seed oil, and improve purity and ecological quality of the tea seed oil.

Description

technical field [0001] The invention relates to a method for extracting tea seed oil, in particular to a method for finely extracting tea seed oil rich in selenium and vitamin E. Background technique [0002] The disadvantage of the existing extraction methods of tea seed oil is that the static baking at a higher temperature (generally above 70°C) is high in temperature and uneven in temperature, which has a great impact on the nutritional quality of tea seed oil; The extraction of pulp, skin, and shell affects the purity and nutritional quality of tea seed oil, especially the special nutrients in tea seed oil. Contents of the invention [0003] The purpose of the present invention is exactly to above-mentioned deficiency, provides a kind of fine extraction method of tea seed oil rich in selenium and vitamin E, it can prevent the damage loss of nutrient in tea seed oil, improve the purity and ecological quality of tea seed oil. [0004] In order to achieve the above objec...
