Problems solved by technology

[0006] The above-mentioned process involves degumming of a large amount of waste oil, alkali refining process and refining high temperature (above 230°C), and vacuum conditions, so the equipment investment is high and the process requirements are harsh; refining under high temperature conditions will make the activity of tea seed oil The substance is greatly damaged, and at the same time, trans fatty acids harmful to the human body will be produced

Embodiment 1

[0015] Pour 500g tea seed oil into the 1L reactor with water bath heating device, add by 40g activated carbon powder and 20g SiO 2 For the mixed adsorbent formed, the temperature was raised to 60°C, the stirrer was started, and the temperature was kept for 25 minutes; the tea seed oil was transferred to the oil filter, and the oil filter with a filter mesh diameter of 7um was used for preliminary filtration and separation, and then passed through An oil filter with a pore size of 0.2um is used for filtration and separation to obtain tea seed oil that is colorless, transparent, and whose quality meets the national first-class standard.

Embodiment 2

[0017] Pour 1000g of tea seed oil into a 2L reactor heated by a water bath, add 200g of activated carbon and 50g of SiO 2 Composed mixed adsorbent, start the agitator, raise the temperature to 70°C, and keep it warm for 10 minutes; transfer the tea seed oil to the oil filter, first pass through the oil filter with a filter mesh aperture of 10um for preliminary filtration and separation, and then pass through An oil filter with a pore size of 0.2um is used for filtration and separation to obtain tea seed oil that is colorless, transparent, and whose quality meets the national first-class standard.

Embodiment 3

[0019] Pour 1000g of tea seed oil into a 2L reactor heated by a water bath, add 150g of activated carbon and 50g of SiO 2 For the mixed adsorbent formed, start the agitator, raise the temperature to 55°C, and keep it warm for 50 minutes; transfer the tea seed oil to an oil filter, first pass through an oil filter with a filter mesh diameter of 8um for preliminary filtration and separation, and then pass through An oil filter with a filter mesh diameter of 0.1um is used for filtration and separation to obtain tea seed oil that is colorless, transparent, and whose quality meets the national first-class standard.

Abstract

The invention discloses a low-temperature refining method of tea seed oil, comprising an absorbing and refining step and a filtering step. The invention adopts the core technology of utilizing a mixed absorption agent to absorb and filter impurities in crude oil, such as free fatty acid, various pigments, phospholipid, and the like to achieve the aim of refining the tea seed oil so as to substitute traditional procedures, such as degumming, deacidifying, bleaching, deodorizing, and the like. The invention adopting a low-temperature physical absorption technology only needs an absorbing and refining pot and filtering equipment, reduces the traditional refining procedures, shortens the production period, lessens the refining loss of the tea seed oil, avoids the execution of the high-temperature process of the traditional refining process, reserves biological active substances and nutrient contents in the tea seed oil, such as vitamins, squalene, and the like and improves the product quality and the health function. The tea seed oil obtained through refining is colorless and transparent and has high yield, equipment investment is small, and the method is simple and suitable for industrial production, keeps the pure natural characteristics of the tea seed oil and greatly improves the added values of the tea seed oil.

Description

technical field [0001] The invention relates to a low-temperature refining method of tea seed oil, and relates to two fields of food processing and chemical industry. Background technique [0002] Tea seed oil is a kind of woody oil unique to my country. It is rich in nutrients and is known as "Oriental olive oil". It contains fatty acids, phospholipids, saponins, vitamin E, carotene and other antioxidants. It is close to or even surpasses olive oil. In addition to food, camellia oil is also an important chemical and pharmaceutical raw material. Folks have used tea seed oil and hair oil to treat children's "red buttocks". With the improvement of people's living standards and the in-depth development and research of tea seed oil, the market for tea seed oil is in short supply. [0003] Because tea seed oil contains a variety of impurities, the color is dark, the transparency is poor, and it has an astringent taste, so the price is relatively low. The market price of camelli...
