1. A process for production of a nano-microemulsion system of plant oil triglycerides, the method includes:
(i) preparing a dispersed phase by heating plant oil triglycerides to a temperature between 60-100° C.;
(ii) preparing a carrier by heating a mixture of propylene glycol monocaprylate and lecithin by a weight ratio of 5-6:1-1.5 to a temperature between 60-100° C. under vacuum by a vacuum rotary evaporator, then cooling to 30° C., followed by, respectively, ultrasonication within 30 minutes, stirring and heating between 60-100° C. within 30 minutes, and introduction of the solution into the vacuum rotary evaporator while stirring at 100° C.;
(iii) adding the carrier to the dispersed phase by a weight ratio of 3-4:1-1.5, wherein the temperature of the dispersed phase after the addition is continuously maintained between 60-100° C. while stirring at 400-800 rpm under vacuum, followed by introduction of the whole mixture through the high-pressure microjet homogenizer;
(iv) adding Tween 80 and Tween 60 to the solution mixture obtained in step (iii) by a weight ratio of 3-4:1-1.5:1-1.5, wherein the temperature of the dispersed phase after the addition is continuously maintained between 60-100° C. while stirring at 400-800 rpm under vacuum; and
(v) forming a nano-microemulsion system of plant oil triglycerides by cooling the obtained mixture to 25° C., followed by homogenization of the mixture by ultrasonication using a homogenizer from 30 to 60 minutes to adopt a droplet size of less than 100 nm, quality control of the resultant product by dissolution thereof in water and measurement of the transparency, in which if the required transparency is not met, continue to heat and measure the transparency every 30 minutes until the required transparency is met, then stop the reaction, and emulsification of the solution mixture in an emulsifying device at a stirring rate between 400-800 rpm to obtain a nano-microemulsion system of plant oil triglycerides.
