Problems solved by technology

[0003] Camellia oleifera seed oil has a deep color and astringent bitter taste, which is related to the small amount of tea saponin and other impurities in the oil, and the acid value of the oil is high, so it must be refined before it can be used in food, cosmetics, and medicine and other industries, but the antifreeze performance of refined tea oil is low, which makes the camellia oil appear precipitates, turbidity and even freezing phenomenon below zero, making the quality of the tea oil unsatisfactory, which is not conducive to the popularization and application of the tea oil
[0004] Patent No. CN201110247402.8 discloses a high-efficiency method for producing high-quality antifreeze tea oil. The key to this scheme is to realize rapid crystallization by adding saturated lipids as crystal seeds during the crystallization process of camellia oil, and obtain antifreeze after filtration and separation. However, due to the addition of saturated fat in this plan, excessive intake of saturated fatty acid will lead to increased blood cholesterol, triacylglycerol, and LDL-C, which will subsequently cause narrowing of the arterial lumen, form atherosclerosis, and increase the risk of coronary artery disease. heart disease risk

Abstract

The invention relates to the technical field of tea oil extraction and particularly relates to an extraction method of tea oil with high frost resistance. The method comprises the following steps of (1) camellia seed activation, (2) aqueous enzyme treatment, (3) slurry explosion, (4) crude oil, and (5) supercritical extraction. The tea oil obtained in the invention has the characteristics of goodquality, good quality stability and frost resistance and contains rich vitamin E, vitamin B and other nutrients.

Description

technical field [0001] The invention relates to the technical field of tea oil extraction, in particular to a method for extracting tea oil with high antifreeze performance. Background technique [0002] Camellia oil is a kind of vegetable oil obtained by processing and refining camellia seeds. The unsaturated fatty acid content in tea oil is more than 80%, and the fatty acid composition is similar to that of olive oil. It is known as "Oriental olive oil". Strong resistance, not easy to oxidize and deteriorate, has the functions of preventing cardiovascular disease, anti-tumor, protecting liver and cooling blood, anti-oxidation and immune regulation, delaying body aging, anti-wrinkle and anti-aging. Camellia oil is widely used in food, medicine and cosmetics industries , Camellia oil also plays a pivotal role in industry. For example, the production of industrial products such as emulsifiers, vaseline, and mechanical lubricants all use camellia oil as a raw material. [000...
