Embodiment 1

[0020] A method for extracting tea seed oil, which is characterized in that: peeling and drying camellia seeds, shelling and pulverizing, enzymatic extraction, centrifugal separation, demulsification, and merging of oils and fats to obtain the finished product of tea seed oil;

[0021] Its concrete method comprises the following steps:

[0022] 1) Peeling and drying: After peeling the fresh camellia seeds, remove the moldy, diseased and insect-damaged seeds, spread them evenly on the material tray, and carry out hot air drying. The drying temperature is controlled at 60°C to reduce the water content to 6%;

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

[0024] 3) Enzymatic hydrolysis and extraction: put the sieved camellia seeds i...

Abstract

The invention provides a method for extracting tea seed oil, which comprises drying the camellia seed, shelling and pulverizing, enzymatically extracting, centrifuging, demulsifying, and merging the oil to obtain the finished product of the tea seed oil. In the present invention, high-quality tea seed oil is produced by using intermittent ultrasonic-assisted hydroenzyme method and demulsification technology combining electrolyte and vacuum film evaporation. The obtained product does not need to be refined, the extraction rate reaches 93.02±0.47%, and the peroxide value is 4.6mmol / kg. The acid value is 1mgKOH / g, and the physical and chemical quality of tea seed oil is good, which meets the national standard. At the same time, the invention has low requirements on equipment, is easy to control, has strong operability and low energy consumption, is suitable for large-scale production of tea seed oil extraction, and opens up a new way out for the deep processing of camellia oleifera industry.

Description

Technical field [0001] The present invention is a field of vegetable oil preparation, which involves a method of extracting tea seed oil. Background technique [0002] Tea seed oil, also known as mountain tea oil, tea oil, etc., is from the tea family ( Camellia ) Mountain tea belongs to plant oral tea ( Camellia oleifra abel ) The fruit is extracted, the color is light yellow, clear and transparent, and the smell is fragrant.Tea seed oil is a unique wood oil in my country. Its fatty acid composition is similar to the best plant oil olive oil recognized in the world. More than 90%, and rich in various functional ingredients such as vitamins A, B, D, E, have the effects of preventing cardiovascular diseases such as hypertension, coronary heart disease, atherosclerosis. [0003] The traditional tea seed oil system is pressed or solvent immersion method.The tea seed oil coat of the squeezing method is deep and turbid, and the oil cakes are high in oil cakes after the oil.At the same...
