Embodiment 1

[0022] Preparation of Eucommia Seed Oil by Aqueous Enzyme Method

[0023] The cleared and washed eucommia seeds were dried (55°C, 12h), cooled to room temperature, crushed and sieved (40 mesh), and the powder was collected for future use. Take 500g of Eucommia ulmoides seed powder in a Erlenmeyer flask, add ultrapure water at a ratio of 1:11g / mL to liquid, vortex and mix for 2min, place in a water bath to inactivate the enzyme (90°C, 10min), and cool to room temperature Adjust the pH to 8, add 2.5g of alkaline endoprotease to it, and place it in a constant temperature oscillator (25 rpm), control the enzymolysis temperature at 53-55°C, and extinguish it again in a water bath after the reaction is completed. Enzyme (90°C, 3min), and ultrasonically treat the enzymolysis solution for 10min. The enzymolysis solution was centrifuged (4000 rpm, 30 min), and the free oil in the upper layer and the emulsion in the middle layer were collected with a pipette for later use.

[0025] Preparation of Eucommia Seed Oil by Aqueous Enzyme Method

[0026]The cleared and washed eucommia seeds were dried (55°C, 12h), cooled to room temperature, crushed and sieved (50 mesh), and the powder was collected for future use. Take 500g of Eucommia ulmoides seed powder in an Erlenmeyer flask, add ultrapure water at a ratio of 1:6g / mL to liquid, vortex and mix for 2min, place in a water bath to inactivate the enzyme (90°C, 10min), and cool to room temperature Adjust the pH to 7.5, add 1.5g of pectinase and 1.5g of cellulase to it respectively, and place them in a constant temperature oscillator (30 rpm), and control the enzymolysis temperature at 45-58°C. After the reaction is completed, Inactivate the enzyme again in a water bath (90°C, 3min), and treat the enzymolysis solution with ultrasonic waves for 10min. The enzymolysis solution was centrifuged (4000 rpm, 30 min), and the free oil in the upper layer and the emulsion in the middle layer were collected with a p...

[0028] Preparation of Microemulsion of Eucommia Seed Oil

[0029] On a mass basis, 22 parts of Eucommia ulmoides seed oils prepared in Examples 1 to 2, 3 parts of middle layer emulsions prepared in Examples 1 to 2, 18 parts of composite surfactants (8 parts of rhamnolipids, 10 parts of spit temperature), 5 parts of ethanol co-surfactant are mixed, the above-mentioned mixed solution is mixed evenly by a magnetic stirrer, and deionized water is added dropwise while stirring. The initial speed of the stirrer is 280 rpm, and the system is initially clear. The addition of deionized water starts to become turbid, and a gel state will appear during this process. At this time, water should be added quickly, and the speed should be increased to 400 rpm, so that the system can quickly pass through the gel phase and become clear again. After adding 57 parts of ultrapure water, the Eucommia seed oil microemulsion was obtained.

Abstract

The invention discloses a preparation method of Eucommia ulmoides seed oil microemulsion. The Eucommia ulmoides seed oil microemulsion prepared by the method uses biosurfactant and eucommia ulmoides seed oil prepared by aqueous enzymatic method as main raw materials, and co-surfactant, emulsion , Water as auxiliary material, prepared by phase inversion emulsification method. The microemulsion prepared by the method not only solves the problem that the eucommia seed oil is not easy to store due to the high content of unsaturated fatty acids, but also reduces the application of chemical surfactants, and has green and safe characteristics. Simultaneously, the dried lyophilized powder of the eucommia seed oil microemulsion has stable properties, high encapsulation rate and wide application range.

Description

technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to a preparation method of eucommia seed oil microemulsion. Background technique [0002] Eucommia ulmoides Oliv. is a plant of Eucommiaceae (Eucommiaceae), a deciduous tree, and is a unique single-family plant in my country. Studies have found that the oil content in Eucommia ulmoides seeds is 27%-33%, and it is rich in unsaturated fatty acids, of which oleic acid is 16%-18%, linoleic acid is 11%-13%, and α-linolenic acid is 61%. ~63%, which is one of the natural vegetable oils with the highest alpha-linolenic acid content found so far. α-linolenic acid is an essential fatty acid for the human body, which belongs to the omega-3 series of fatty acids, and can be metabolized into polyethylenically unsaturated fatty acids such as EPA and DHA in the human body. Pharmacological experiments have proved that α-linolenic acid has various physiological functions such as...
