Embodiment 1
[0027] Embodiment 1, preparation camellia oil microcapsules
[0028] Weigh 0.8 parts by mass of sodium starch octenyl succinate and add 2 parts by mass of water, and stir at 70°C to form an aqueous solution of sodium starch octenyl succinate with a concentration of 40% (g / 100ml). The solution was cooled to 40°C, and then 1 part by mass of camellia oil was added thereto, and the stirring was continued until camellia oil colostrum was formed, and then the colostrum was homogenized under high pressure for 3 times under 1500 bar pressure to form a milky white emulsion. The milky white emulsion is dried by spraying, and the conditions are as follows: the air inlet temperature is 190° C., and the air outlet temperature is 50° C. to obtain white camellia oil microcapsule powder. The average particle size of the white camellia oil microcapsule powder is 736 nm by laser particle size analyzer .
Embodiment 2
[0029] Embodiment 2, preparation camellia oil microcapsules
[0030] Weigh 1 mass part of sodium starch octenyl succinate and add 3 mass parts of water, and stir at 75°C to form an aqueous solution of sodium starch octenyl succinate with a mass concentration of 33%. The solution was cooled to 35°C, and then 1 part by mass of camellia oil was added to the solution, and the stirring was continued until camellia oil colostrum was formed, and then the colostrum was homogenized under high pressure for 4 times under the pressure of 800 bar to form a milky white emulsion. The milky white emulsion is dried by spraying, and the conditions are as follows: the air inlet temperature is 190° C., and the air outlet temperature is 40° C. to obtain white camellia oil microcapsule powder. The average particle diameter of the white camellia oil microcapsule powder is 628 nm by laser particle size analyzer .
Embodiment 3
[0031] Embodiment 3, preparation camellia oil microcapsules
[0032] Weigh 4 parts by mass of sodium starch octenyl succinate and add to 10 parts by mass of water, and stir at 80° C. to form an aqueous solution of sodium starch octenyl succinate with a mass concentration of 40%. Cool the solution to 30°C, then add 1 part by mass of camellia oil and 0.3 parts by mass of vitamin E to the solution, continue to stir until the camellia oil colostrum is formed, and then homogenize the colostrum under high pressure for 4 times under the pressure of 1000 bar Forms a milky white emulsion. The milky white emulsion is spray-dried under the following conditions: the air inlet temperature is 200° C., and the air outlet temperature is 60° C. to obtain white camellia oil microcapsule powder. The average particle diameter of the white camellia oil microcapsule powder is 461 nm by laser particle size analyzer .
