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 in the container, slowly add 20g of modified starch under stirring state, stir well, and let it stand overnight to dissolve. 40 g of 5% natural beta-carotene oil was added with 2 g of soybean lecithin and 0.2 g of TBHQ, and heated to 120° C. in an oil bath to dissolve it to prepare an oil phase. Put 300g of water in the container, add 8g of maltodextrin, 16g of beta-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 standby modified starch solution to 70°C, added to the above solution to make an aqueous phase. The oil phase was added to the water phase, the temperature was kept at 80°C, and emulsification was carried out with an emulsifying machine, the rotation speed was 4000 rpm, and the time was 20 minutes. The emulsified liquid is homogenized, and the pressure is 40kg / cm2 , the homogenized material is spray-dried, the inlet temperature is 195°C, and the outlet temperatu...

Embodiment 2

[0051] Put 200g of water in the container, slowly add 26g of modified starch under stirring state, stir well, and let it stand overnight to dissolve. 50 g of 20% natural beta-carotene oil was added with 1 g of Tween 60 and 0.5 g of natural VC, and heated to 190° C. in an oil bath to dissolve it to prepare an oil phase. Put 200g of water in the container, add 5g of maltodextrin, 6g of beta-cyclodextrin, 1g of soybean lecithin, 8g of lactose, and 1g of potassium sorbate, stir and heat to 75°C, and heat the standby modified starch solution to 50°C, Add to the above solution to make an aqueous phase. The oil phase was added to the water phase, the temperature was kept at 75° C., and emulsification was carried out with an emulsifying machine, the rotation speed was 3000 rpm, and the time was 30 minutes. The emulsified liquid is homogenized, and the pressure is 40kg / cm 2 , the homogenized material is spray-dried, the inlet temperature is 200°C, and the outlet temperature is 90°C, ...

Embodiment 3

[0053] Put 100g of water in the container, slowly add 20g of modified starch under stirring state, stir well, and let it stand overnight to dissolve. 10 g of 5% natural beta-carotene oil was added with 0.8 g of soybean lecithin and 0.1 g of TBHQ, then heated to 120° C. in an oil bath to dissolve it to prepare an oil phase. Put 300g of water in the container, add 5g of maltodextrin, 5g of beta-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 standby modified starch solution to 40°C, added to the above solution to make an aqueous phase. The oil phase was added to the water phase, the temperature was kept at 60°C, and emulsification was carried out with an emulsifying machine, the rotation speed was 2000 rpm, and the time was 10 minutes. The emulsified liquid is homogenized, and the pressure is 30kg / cm 2 , the homogenized material is spray-dried, the inlet temperature is 150°C, and the outlet temper...

Abstract

The invention discloses a natural beta- carotene microcapsule and process for preparation, wherein the microcapsule comprises the following raw materials (by weight portion), natural beta-carotene oil solution 10-50, modified starch 20-32, beta cyclodextrin 5-18, maltodextrin 5-15, oil phase emulsifying agent 0.8-2, aqueous phase emulsifying agent 0.7-1.5, dispersing agent 5-15, preservative agent 0.5-1, anti-oxidizing agent 0.1-0.5.

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 kind of carotenoid that is synthesized and extracted by natural organisms’ own physiology. The main component is β-carotene, and it also contains a small amount of carotenoids. The non-toxic and nutritious food additives recognized by the Joint Committee on Food Additives of the World Health Organization (WHO) belong to the "A" category of nutritional pigments, and have a good effect on preventing "three Cs", namely cancer, cardiovascular diseases and cataracts. At present, it has been approved for use in 52 countries or regions in the world, and 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, which can effectively remove free radicals and quench singlet oxygen in the human body; it can ...
