Problems solved by technology

Its weak point is that there are solvent residues in the product, which affects the quality, and increases the process steps. With gelatin as the wall material, its antioxidant effect is poor; in the CN 1038220C document, it is characterized in that carotene, emulsifier, Hydrocolloid, dextrin, and water are mixed in a certain proportion, after emulsification and homogenization, β-carotene granules are obtained through granulation, drying and other steps
Its weak point is that the drying process selects the drying method, the temperature is high, the time is long, the efficiency is low, and the loss of β-carotene is relatively large; in the CN 1082890A document, it is characterized in that the oil phase is made by dissolving β-carotene at low temperature, and then Mix with water phase composed of gum arabic, emulsifier, stabilizer, essence, etc., emulsify and spray dry to make microcapsule particles
Its shortcoming is that low temperature dissolves β-carotene, although it can effectively protect β-carotene from being destroyed, its solubility is very low, and the content of β-carotene in the product is between 0.1-1%. Unable to produce high content beta-carotene powder

Embodiment 1

[0049] Put 100g of water into the container, slowly add 20g of modified starch under stirring state, stir well, let it stand overnight to make it dissolve. Add 40 g of 5% natural β-carotene oil, add 2 g of soybean lecithin and 0.2 g of TBHQ, heat the oil bath to 120° C. to dissolve it, and make the oil phase. Put 300g of water into the container, add 8g of maltodextrin, 16g of β-cyclodextrin, 1.5g of sorbitol fatty acid ester, 15g of maltose, and 0.5g of sodium benzoate, stir and heat to 80°C, and heat the spare modified starch solution to 70°C, added to the above solution to make the water phase. Add the oil phase to the water phase, keep the temperature at 80°C, and emulsify with an emulsifier at 4000 rpm for 20 minutes. Homogenize the emulsified liquid with a pressure of 40kg / cm 2 , the homogenized material is spray-dried at an inlet temperature of 195°C and an outlet temperature of 75°C to produce 2.1% natural beta-carotene microcapsules.

Embodiment 2

[0051]Put 200g of water into the container, slowly add 26g of modified starch under stirring, stir well, let it stand overnight to dissolve it. 20% natural β-carotene oil 50g, add 1g Tween 60, natural V C After 0.5 g, the oil bath was heated to 190° C. to dissolve it to form an oil phase. Put 200g of water into the container, add 5g of maltodextrin, 6g of β-cyclodextrin, 1g of soybean lecithin, 8g of lactose, and 1g of potassium sorbate, stir and heat to 75°C, and heat the spare modified starch solution to 50°C. Add to the above solution to make the water phase. Add the oil phase to the water phase, keep the temperature at 75°C, and emulsify with an emulsifier at 3000 rpm for 30 minutes. Homogenize the emulsified liquid with a pressure of 40kg / cm 2 10.05% natural beta-carotene microcapsules can be prepared by spray drying the homogenized material at an inlet temperature of 200°C and an outlet temperature of 90°C.

Embodiment 3

[0053] Put 100g of water into the container, slowly add 20g of modified starch under stirring state, stir well, let it stand overnight to make it dissolve. After adding 10 g of 5% natural β-carotene oil, 0.8 g of soybean lecithin and 0.1 g of TBHQ, the oil bath was heated to 120° C. to dissolve it to form an oil phase. Put 300g of water into the container, add 5g of maltodextrin, 5g of β-cyclodextrin, 0.7g of sorbitol fatty acid ester, 5g of glucose, and 0.5g of sodium benzoate, stir and heat to 50°C, and heat the spare modified starch solution to 40°C, added to the above solution to make the water phase. Add the oil phase to the water phase, keep the temperature at 60°C, and emulsify with an emulsifier at 2000 rpm for 10 minutes. Homogenize the emulsified liquid with a pressure of 30kg / cm 2 , the homogenized material is spray-dried at an inlet temperature of 150°C and an outlet temperature of 70°C to produce 1.06% natural beta-carotene microcapsules.

Description

technical field [0001] The invention relates to a natural beta-carotene microcapsule and a preparation method thereof. Background technique [0002] Natural β-carotene refers to a carotenoid that is physiologically synthesized and extracted by natural organisms. The main component is β-carotene, and it also contains a small amount of carotenoid. The non-toxic and nutritious food additive approved by the Joint Committee on Food Additives of the World Health Organization (WHO), belongs to the "A" category of nutritional pigments, and has a good effect on preventing the "three Cs", namely cancer, cardiovascular disease and cataract. At present, 52 countries or regions in the world have approved its use, and it has been approved by the US Food and Drug Administration (FDA) and listed in the US Pharmacopoeia. [0003] Natural β-carotene has a strong antioxidant effect, can effectively remove free radicals in the human body and quench singlet oxygen; can stimulate the immune syst...
