Problems solved by technology

According to this method, a large amount of active composition can be obtained, but this method uses hydrocarbon solvents, especially aliphatic hydrocarbons with 6 carbon atoms, such as isohexane, which will easily cause organic solvent residues in food
[0007] Polymer wall materials are widely admired for their good film-forming properties, however they also cost more
Although small molecules such as monosaccharides and oligosaccharides can theoretically be used as wall materials for microcapsule powder, they are rarely used in industrial production because the quality of the product cannot be controlled.

Embodiment 1

[0072] Heat 50 g of borage oil in a water bath at 50° C., add 0.1 g of natural mixed vitamin E and fully stir to obtain an oil phase. The water phase is composed of 30g of modified starch, 20g of maltodextrin (national standard MD150), and 100g of water, and the temperature of the water phase is 25°C. Add the oil phase to the water phase, emulsify with a high-speed shearing machine for 10 minutes, and then use a high-pressure homogenizer to homogenize the emulsion twice, so that the particle size of the oil droplets is less than 1 μm. The homogenization pressure used: low pressure 16MPa, high pressure 50MPa. The emulsion obtained above was dried in a spray drying tower, and the spray drying conditions were as follows: the inlet air temperature was 180°C, and the outlet air temperature was 80°C. The particle size of the microcapsules after drying is 80-160 mesh, the oil carrying capacity of the product is 50%, the surface oil content is 0.68%, the rehydration stability is good...

Embodiment 2

[0075] 44g of modified starch, 1.1g of polyglycerol fatty acid ester and 30g of sucrose were placed in a 250ml container, 100ml of purified water was added thereto, and the mixture was stirred rapidly at 25°C to form a matrix solution. At 55°C, 1.6g of low-alpha mixed tocopherols were fully mixed into 48g of lutein ester oil suspension (content 15%, crystal particles in it were less than 2μm). Then slowly pour the oil phase mixture into the above-mentioned matrix solution for high-speed shear emulsification, and the emulsification speed of the shearer is 8000-12000r / min. The average particle size of the discontinuous phase of the emulsion formed at this time is about 4 μm. Then the emulsion is circulated and homogenized under high pressure at 50Mpa until the average particle size of the discontinuous phase in the matrix solution is 1000nm or smaller. Finally, the emulsion is spray-dried to obtain a cold-water dispersible lutein ester microcapsule powder with a content of abou...

Embodiment 3

[0079] 44g of modified starch, 1.1g of polyglycerol fatty acid ester and 30g of sucrose were placed in a 250ml container, 100ml of purified water was added thereto, and the mixture was stirred rapidly at 25°C to form a matrix solution. At 55°C, 1.6g of low-alpha mixed tocopherols were fully mixed into 48g of lutein ester oil suspension (content 15%, crystal particles in it were less than 2μm). Then slowly pour the oil phase mixture into the above-mentioned matrix solution for high-speed shear emulsification, and the emulsification speed of the shearer is 8000-12000r / min. The average particle size of the discontinuous phase of the emulsion formed at this time is about 4 μm. Then the emulsion is circulated and homogenized under high pressure at 50Mpa until the average particle size of the discontinuous phase in the matrix solution is 1000nm or smaller. , the emulsion is sprayed through a low-speed rotating atomizing disc to form droplets of 180-400 μm, and then fed into cold mo...

Abstract

The invention provides a preparation method of a cold water dispersion type microcapsule powder; the method comprises the procedures of water phase preparation, wall material used in the water phase preparation is obtained via mixing modified starch with combination A according to the mass ratio of 1: 0.1 to 3.5, wherein, the combination A is selected from monosaccharide, oligosaccharides, polysaccharide or alsace gum, or the mixture of the two or more than two substances which are mixed at any ratio. The preparation method has the advantages that low-priced micro-molecular component which has certain emulsification stability is introduced in the selection of the wall material, which enables the emulsification process to be easier, reduces the production cost and causes the product quality to be more stable. The microcapsule products obtained with the production method are cold water dispersion products with excellent rehydration stability; the oil content on the surface is much lowerand the oil-loading amount is much higher. The production process described in the method generates no waste residue or waste water, thus belonging to the green environmentally friendly technique.

Description

technical field [0001] The invention relates to a preparation method of cold water dispersible microcapsule powder, in particular to a preparation method of fat-soluble liquid cold water dispersible microcapsule powder with high embedding rate. Background technique [0002] The microencapsulation technology of fat-soluble liquid has been applied in many fields since its discovery. It can achieve the following purposes: ①Protect the core material, that is, effectively prevent the adverse effects of external environmental factors on the core material, such as pH value, oxygen, humidity, heat, light and other substances; ②Isolate incompatible components , to prevent chemical reactions between components, improve their stability, and keep the quality longer; ③Controlled release, which can artificially and effectively control the release of the core material, so that the original effectiveness of the core material can be maximized; ④ Shield the taste and smell, cover the peculia...
