Example Embodiment

[0019] Example 1

[0020] A method for extracting tea seed oil, characterized in that: the camellia oleifera seeds are peeled and dried, shelled and pulverized, enzymatically extracted, centrifuged, demulsified, and combined with oils and fats to obtain finished tea seed oil;

[0021] The specific method includes the following steps:

[0022] 1) Peeling and drying: After peeling the fresh camellia seeds, remove the grains damaged by mildew and pests and diseases, spread them evenly on the material tray, and dry them with hot air. The drying temperature is controlled at 60 °C to reduce the water content to 6%;

[0023] 2) Shelling and crushing: using the method of mechanical shelling, put the dried camellia seeds into the tea seed shelling machine to break the shells, and separate the kernels and shells by wind separation, and pulverize the shelled camellia seeds. And pass through a 70-mesh sieve for use;

[0024] 3) Enzymatic extraction: put the sieved camellia seeds into...

Abstract

The invention provides a method for extracting tea-seed oil. The method comprises the following steps: drying tea seeds, removing shells, crushing, carrying out enzymolysis, extracting, centrifugally separating, carrying out demulsification and combining grease to obtain a tea-seed oil finished product. According to the method for extracting the tea-seed oil, the high-quality tea-seed oil is provided by applying a demulsification technology combining an interval ultrasonic-assisted aqueous enzymatic method as well as electrolyte and vacuum thin film evaporation; an obtained product does not need to be refined, the extraction rate is up to 93.02+/-0.47%, the peroxidation value is 4.6mmol/kg and the acidic value is 1mgKOH/g; the tea-seed oil is good in physicochemical quality and meets the national requirements. Meanwhile, the requirements on equipment is not high; the method is easy to control, strong in operability and small in energy consumption, is suitable for large-scale production for extracting the tea-seed oil and explores a novel way for deep processing of the tea-seed oil industry.

Description

technical field [0001] The invention belongs to the field of vegetable oil preparation, in particular to a method for extracting tea seed oil. Background technique [0002] Camellia seed oil, also known as camellia oil, camellia oil, etc., is from the family Theaceae ( Camellia ) Camellia oleifera ( Camellia oleifera Abel ) extracted from the fruit, the color is light yellow, clear and transparent, and the smell is fragrant. Tea seed oil is a unique woody oil in my country. Its fatty acid composition is similar to that of olive oil, the best vegetable oil recognized in the world. It does not contain erucic acid, behenic acid and other components that are difficult to digest and absorb. Its unsaturated fatty acid content is More than 90%, and rich in vitamins A, B, D, E and other functional ingredients, it has the effect of preventing cardiovascular diseases such as hypertension, coronary heart disease and atherosclerosis. [0003] The traditional tea seed oil production m...
