Embodiment 1

[0023] Weigh 100 g of lutein ester powder (content: 57%) and place it in a beaker, add 50 g of corn germ oil therein, place it in a water bath at 50° C. and stir and heat for 30 minutes to completely dissolve the lutein ester powder to obtain lutein Vegetarian oil phase. Weigh 500 g of modified starch and 200 g of maltodextrin, and dissolve them in 1000 mL of distilled water to prepare a wall material solution. Add the mixed core material into the wall material solution, add 2g of emulsifier (Span: Tween = 1:1) and 5g of vitamin C at the same time, mix at 60°C for 30min to form colostrum, and then press the colostrum under 30Mpa pressure Homogenize 3 times to form a stable emulsion. The emulsion was spray-dried and granulated, and the spray-drying conditions were as follows: the inlet air temperature was 160°C, and the feeding speed was 10mL / min to obtain lutein ester microcapsules.

Embodiment 2

[0025] Weigh 50 g of lutein ester powder (content: 67%) and place it in a beaker, add 50 g of soybean oil to it, place in a water bath at 60° C. and stir and heat for 60 minutes to completely dissolve the lutein ester powder to obtain lutein Ester oil phase. Weigh 500 g of modified starch and 500 g of maltooligosaccharide, dissolve them in 1500 mL of distilled water to prepare a wall material solution. Add the mixed core material into the wall material solution, add 2g of emulsifier (propylene glycol fatty acid ester: Tween = 1:1) and 3g of vitamin E at the same time, mix at 65°C for 30min to form colostrum, and then put the colostrum under a pressure of 35Mpa Homogenize twice under high pressure to form a stable emulsion. The emulsion was spray-dried and granulated, and the spray-drying conditions were as follows: the inlet air temperature was 170°C, and the feeding speed was 20mL / min to obtain lutein ester microcapsules.

Embodiment 3

[0027] Weigh 100g of lutein ester powder (content is 57%) and put it in a beaker, add 100g of vegetable oil (corn germ oil: peanut oil=1:1), place it in a water bath at 60°C and stir for 40min to make the lutein yellow. The lutein ester powder is completely dissolved to obtain the lutein ester oil phase. Weigh 100 g of gum arabic, 200 g of modified starch, and 500 g of maltodextrin, and dissolve them in 1500 mL of distilled water to prepare a wall material solution. Add the mixed core material into the wall material solution, add 2g of emulsifier (propylene glycol fatty acid ester: lecithin = 1:1) and 5g of sodium ascorbate at the same time, mix at 70°C for 30min to form colostrum, and then put the colostrum under a pressure of 40Mpa Homogenize once under high pressure to form a stable emulsion. The emulsion was spray-dried and granulated, and the spray-drying conditions were as follows: the inlet air temperature was 165°C, and the feeding speed was 15mL / min to obtain lutein ...

Abstract

The invention discloses a lutein ester microcapsule, mainly comprising core material lutein ester powder, vegetable oil for dissolving the core material, a wall material, an antioxidant and an emulsifier, wherein the lutein ester microcapsule is prepared by the processes of preparing an oil-phase solution and a water-phase solution, and then mixing and emulsifying the oil-phase solution and the water-phase solution. No organic solvent is used in the overall process of preparation of the lutein ester microcapsule, the microcapsule wall material mainly is carbohydrate, and is wider in source and higher in safety, and the obtained lutein ester microcapsule is applicable to application in the fields such as a food and a medicine, and has high commercial value. In addition, the lutein ester microcapsule prepared by the method can be stably stored for a long period of time at room temperature, and has important significance on storage, transportation and use of the lutein ester.

Description

technical field [0001] The invention relates to the technical field of deep processing of bioactive substances, in particular to a lutein ester microcapsule and a preparation method thereof. Background technique [0002] The chemical name of lutein ester is lutein palmitate, which is a kind of oxygen-containing carotenoid ester widely present in marigold, cabbage, corn and other plants, among which the content is most abundant in marigold. Lutein ester has multiple biological activities such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, anti-cardiovascular disease, etc., especially as a strong efficacy factor in visual protection, it can prevent senile cataract and protect the retina and age-related macular degeneration. [0003] Under certain conditions, lutein can be obtained by saponification of lutein esters. Due to the highly unsaturated structure of lutein, it is easily affected by physical and chemical factors, and loses biological activity an...
