Example Embodiment

[0018] 1. Examples of different types of distillates

[0019] (1) Add 0.6kg urea to 4.5L 95% ethanol, dissolve it at 60~80℃, then add 1kg soybean oil vacuum deodorant distillate, stir well, vacuum degassed, sealed package, put in an ultra-high pressure container and apply 300MPa pressure 1 hour, take it out and filter to obtain a filtrate rich in VE, PUFA and squalene. The acid value of the filtrate (mg KOH / g) can be reduced from 60 to below 40; the recovery rate of PUFA and squalene (total content in the filtrate / The total content in the raw materials) is above 85%, and the VE recovery rate can reach 95%.

[0020] (2) Add 1.5kg of urea to 11.25L of 95% ethanol, dissolve it at 60~80℃, then add 1kg of rapeseed oil vacuum deodorized distillate, stir well, vacuum degassed, sealed package, and place in an ultra-high pressure container to apply 250MPa After 1 hour of pressure, take it out and filter to obtain a filtrate rich in VE, linoleic acid and squalene. The respective recovery r...

Abstract

The invention discloses a method for gathering/recovering VE (Vitamins E), squalene and polyunsaturated fatty acids from the deodorized distillate of plant oil. Specifically, the method comprises the following steps: adopting urea and a solvent as addition agents; mixing the addition agents with the distillate so as to dissolve the addition agents in the distillate; carrying out flexible packaging, vacuum degassing and sealing; applying a super high pressure for quickly crystallizing and agglomerating saturated fatty acids, monounsaturated fatty acids, fatty hydrocarbons, sterols and the like in the distillate; adsorbing a large quantity of impurities with an inclusion compound; carrying out pressure filtering and separating to obtain filter residue and filtrate; removing the solvent from the filtrate to obtain the VE, squalene and polyunsaturated fatty acids with high concentration. According to the method, the recovery rates of the VE, squalene and polyunsaturated fatty acids are all more than 80%, and neutral oil can be reserved.

Description

1. Technical field [0001] The present invention relates to a separation process, in particular to a crystallization separation method, specifically a method for enriching / recovering vitamin E (VE), squalene and polyunsaturated fatty acids (PUFA) from vegetable oil deodorization distillates Ultra-high pressure urea packet separation method. 2. Background technology [0002] Vegetable oil vacuum deodorization distillates are rich in various functional components, such as free fatty acids (FFA), fatty acid esters, VE, squalene, phytosterols, etc. These substances have important development and utilization value, but they often need to be separated and purified before application. Previously, a variety of separation methods have been developed, such as molecular distillation, saponification, freeze-out, column chromatography, and urea wrapping. [0003] Molecular distillation is widely used, which requires precise control of high vacuum conditions and high production costs; sa...
