Problems solved by technology

In the above-mentioned patents, various materials such as gum arabic are used for the package material, which is unfavorable to product quality control. Because the viscosity of high-concentration gum arabic aqueous solution is relatively large, it brings great inconvenience to spray drying. In the patent CN 1709090A, the preparation temperature If it is too high, it will easily cause camellia oil to oxidize and lose its activity, and a monoglyceride emulsifier is also added

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 .

Abstract

The invention discloses camellia oil microcapsule powder and a preparation method thereof. The camellia oil microcapsule powder comprises a core material and a capsule material for coating the core material, wherein the core material includes 1 part of camellia oil by weight, and the capsule material includes 0.8-9 parts of modified polysaccharide-SSOS (starch sodium octenyl succinate) by weight.The preparation method is as follows: camellia oil is added into an aqueous solution of SSOS, the solution is stirred to be a uniform emulsion system, the emulsion is subjected to high-pressure homogenizing through a high-pressure homogenizing machine to form a camellia oil emulsion, then camellia oil emulsion is subjected to spray drying or freeze drying, and finally the while camellia oil microcapsule powder with the grain size less than 1000 nm can be obtained and has high stability and good flowability. The camellia oil microcapsule powder keeps the activity of camellia oil, improves the stability and the bioavailability of camellia oil, and can be applied to food and health care products.

Description

technical field [0001] The invention relates to a camellia oil microcapsule powder and a preparation method thereof. Background technique [0002] Camellia oil (also known as Camellia oil, Camellia oil) is a kind of woody edible vegetable oil obtained by pressing the mature nuts of Camellia (Camellia), a special product in my country, containing 80% monounsaturated fatty acid oleic acid. It is rich in essential polyunsaturated fatty acids such as linoleic acid and linolenic acid, etc. The composition of fatty acids is similar to that of olive oil, and it is also a high-quality edible oil like olive oil, known as oriental olive oil. In addition, camellia oil contains trace active ingredients such as camellia glycosides, camellia saponins, and tea polyphenols, which are lacking in olive oil. It also contains vitamin E and various trace elements. Containing erucic acid, regular consumption of camellia oil has nutritional and health effects such as lowering blood lipids, enhanci...
