Embodiment 1

[0015] A kind of extracting method of tea seed oil is characterized in that it is made up of following steps:

[0016] 1) The picked tea seeds are removed from impurities, cleaned, treated with microwave for 100 seconds, shelled, crushed to 60 mesh, and the irradiation source is 60 Co rays, the irradiation dose is 6KGy, the dose rate is 1KGy / h, and the dynamic continuous irradiation is 5 hours;

[0017] 2) Mix the tea seed granules obtained in step 1 with water at a ratio of 1:4-6, adjust the pH value to 6-6.5, and the temperature to 80-85°C, add 0.06-0.07% high-temperature amylase to enzymatically hydrolyze 3- 3.5 hours, inactivate the enzyme activity, adjust the pH value to 6-6.5, the temperature is 55-60 ℃, add 0.06-0.07% acid protease, enzymolysis for 3-3.5 hours, adjust the pH of the solution to neutral, at the temperature of 50-55 ℃ , 400-450W ultrasonic treatment for 35-40 minutes;

[0018] 3) Add 0.2-0.23% papain to the product obtained in step 2 for enzymatic hydrol...

Abstract

The invention relates to a method for extracting tea seed oil. The method aims at a defect that the enzyme cost is high in an aqueous enzymatic method, and oil cell structures are destroyed by microwave, ultrasonic and irradiation treatment, so as to change physical properties and further increase the oil extraction ratio. under the action of microwaves, unsaturated oils and fats can generate epoxy compounds due to thermal oxidation, so that the process of hydrolysis can be controlled, and passivation of lipids, lipoxygenase and other enzymes in oils and fats is realized; the microwave treatment is conducive to maintaining the stability of the unsaturated fatty acids .

Description

technical field [0001] The invention mainly relates to a method for extracting tea seed oil. Background technique [0002] Camellia oleifera seed oil has broad application prospects in food, medical, cosmetics, industry and other industries. In the food industry, camellia seed oil is suitable for frying and baking food, and can also be used in the processing of margarine, powdered oil, shortening, etc.; in medical treatment, camellia seed oil for external skin care can moisturize and soften the skin, and can prevent mosquito bites , scabies and other skin diseases and can absorb ultraviolet rays; it can treat burns, scalds, tinea corporis, chapped or soft tissue contusions, etc. As a traditional Chinese medicine, tea seed oil is often used to prepare pills and ointments, and tea seed oil can also be used to make medical injections; In terms of cosmetics, it can be used as pomade to make hair black, shiny, moist and soft; in industry, oleic acid and its esters can be produce...
