Embodiment 1

[0037]S1. Under the condition of 50℃~80℃, wall material (60kg sodium starch octenyl succinate), dispersant (58kg maltodextrin, 58kg starch syrup), water phase antioxidant (1kg ascorbic acid and 1kg D-iso Sodium ascorbate), emulsifier (0.5kg modified soybean lecithin), thickener (0.1kg sodium carboxymethyl cellulose), acidity regulator (1kg citric acid) were added to 300kg of deionized water, stirred until dissolved, and prepared The aqueous phase was obtained and kept at 50°C to 70°C for later use.

[0038] S2. Mix the core material (20kg natural carotene 15% oil suspension) with oil-phase antioxidants (0.2kg vitamin E, 0.2kg L-ascorbyl palmitate), under the condition of inert gas and closed space, 160 ℃ ~ 180 Heating at ℃ for 2-5 minutes to obtain an oil phase, rapidly cooling to 70℃-90℃ and keeping it warm for later use.

[0039] S3. Inject the oil phase into the water phase, disperse at high speed for 3 minutes to 10 minutes with a high-speed shearing machine of 4000 rpm t...

Embodiment 2

[0042] The preparation method of the present embodiment is the same as that of Example 1, and different from Example 1, the components and consumption of the water phase and the oil phase are:

[0043] Wall material (40kg sodium starch octenyl succinate), dispersant (134kg maltodextrin), water phase antioxidant (1kg sodium ascorbate and 2kg D-sodium erythorbate), emulsifier (0.5kg sodium caseinate), Thickener (0.5kg gelatin), acidity regulator (1kg monosodium citrate);

[0044] The core material (20kg natural carotene 15% oil suspension) is mixed with oil phase antioxidants (0.5kg tert-butyl hydroquinone, 0.5kg butyl hydroxyanisole).

Embodiment 3

[0046] The preparation method of the present embodiment is the same as that of Example 1, and different from Example 1, the components and consumption of the water phase and the oil phase are:

[0047] Wall material (60kg sodium starch octenyl succinate, 10kg gum arabic, 10kg porous starch), dispersant (52kg maltodextrin, 40kg sucrose), water phase antioxidant (1kg ascorbic acid and 1kg tea polyphenol), emulsifier ( 0.4kg modified soybean lecithin, 0.7kg glyceryl monostearate, 0.3kg glycerin), thickener (2kg gelatin), acidity regulator (2kg sodium citrate);

[0048] The core material (20kg natural carotene 15% oil suspension) is mixed with oil phase antioxidants (0.4kg vitamin E, 0.2kg butyl hydroxyanisole).

Abstract

The invention belongs to the technical field of natural product microcapsules and discloses natural carotene microencapsulated powder and a preparation method thereof. The natural carotene microencapsulated powder is prepared from the following components in parts by weight: 5 to 15 parts of a core material, 20 to 80 parts of a wall material, 0.1 to 2 parts of an oil-phase antioxidant, 0.1 to 5 parts of a water-phase antioxidant, 0.1 to 7 parts of an emulsifier, 0.1 to 2 parts of a thickener, 0.1 to 2 parts of an acidity regulator and 30 to 140 parts of a dispersant, wherein the core material is natural carotene oil suspension liquid; the wall material is selected from one or more of starch sodium octenyl succinate, Arabic gum and porous starch; the dispersant is selected from one or more of maltodextrin, sucrose and starch syrup. By regulating a formula and a spraying process, the natural carotene microencapsulated powder which has a high encapsulation rate, can be dissolved in cold water and has good stability is prepared.

Description

technical field [0001] The invention belongs to the technical field of natural product microcapsules, in particular to a natural carotene microcapsule powder and a preparation method thereof. Background technique [0002] Natural carotene is mainly extracted and refined from plants through solvent extraction. The main coloring substances are β-carotene and α-carotene, and β-carotene accounts for the majority. Natural carotene has a detoxifying effect and is an indispensable nutrient for maintaining human health. It has significant functions in anti-cancer, prevention of cardiovascular diseases, cataracts and anti-oxidation, and thus prevents aging and various degenerative diseases caused by aging. [0003] The main component of natural carotene, β-carotene, contains a considerable number of cis-isomers, such as 9-cis β-carotene and 15-cis β-carotene, and literature shows that 9-cis The isomer has stronger antioxidant activity than the all-trans isomer. [0004] It has bee...
