preparation example Construction

[0024] The above preparation method can be carried out under the protection of nitrogen. The use of nitrogen protection can eliminate the influence of oxygen in the environment on nutrients and ensure the stability of fat-soluble nutrients during the preparation of microcapsules.

[0025] The water used in the above water phase can be deoxidized in advance to further eliminate the influence of oxygen in the environment and improve the stability of fat-soluble nutrients in the microcapsule preparation process. In the water phase, the mass ratio of the hydrophilic wall material to water is 0.5-1:1.

[0026] The above-mentioned drying process may be spray drying, spray granulation-fluidized drying and the like.

[0029] Vitamin A microcapsule and its preparation

[0030] Components:

[0031]

[0032]Accurately weigh 360Kg of vitamin A acetate crystals, put it into the melting oil kettle, heat up to melt all the materials to obtain molten oil; put 1000L of drinking water into the batching kettle, and then throw in 300Kg of gelatin, 100Kg of glucose, 20Kg of vitamin C, and 110Kg of dextrin. Warm up and stir to dissolve to obtain a hydrosol solution. Use a pump to pump the melted oil in the melting oil kettle and the hydrosol solution in the batching kettle into the 5-stage cavitation emulsifier in series with a high-pressure pump, adjust the pressure to 400Mpa, and carry out continuous emulsification to obtain vitamin A acetate emulsion at the outlet , the emulsion is continuously fed into a spray granulation tower sprayed with cornstarch for granulation, and then fluidized and dried to obtain vitamin A acetate particles, and the vitamin A acetate retention rate in the production pro...

[0034] Vitamin D3 microcapsules and its preparation

[0035] Components:

[0036]

[0037] Put 55Kg of vitamin D3 oil into the melting oil kettle, add 5Kg of BHT to the kettle, heat up to melt all the materials to obtain molten oil; put 980L of drinking water into the batching kettle, and then put in 200Kg of white sugar, 150Kg of gelatin, and 630Kg of dextrin, Warm up and stir to dissolve to obtain a hydrosol solution. Use a pump to pump the melted oil in the above-mentioned melting oil tank and the hydrosol solution in the batching tank into the 4-stage series cavitation emulsifier with a high-pressure pump, adjust the pressure to 200Mpa, and carry out continuous emulsification to obtain vitamin D3 emulsion at the outlet. The emulsion is continuously passed into a spray drying tower for spray drying to obtain vitamin D3 dry powder, and the calculated retention rate of vitamin D3 in the production process is 99.2%. The vitamin D3 dry powder was placed at 25°C for a stabi...

Abstract

The invention discloses fat-soluble nutrient microcapsules and a preparation method thereof. The fat-soluble nutrient microcapsules comprise the following components in percentage by weight: 0.2-51.6%of fat-soluble nutrients, 0.2-5.0% of an antioxidant, 41.4-97.6% of wall materials and 2.0-5.0% of water. The ratio of fat-soluble nutrients keeping activity to initially-added fat-soluble nutrientsin the fat-soluble nutrient microcapsules is (0.99-0.997) to 1. The preparation method of the fat-soluble nutrient microcapsules comprises the processing of emulsification and granulation, wherein theemulsification is performed in a cavitation emulsifier. Through the preparation method, the losses of nutrient active substances of the fat-soluble nutrient microcapsules can be reduced, and the stability is high.

Description

technical field [0001] The invention relates to the field of food and feed additives, in particular to a fat-soluble nutrient microcapsule and a preparation method thereof. Background technique [0002] The fat-soluble nutrients described in the present invention mainly refer to fat-soluble vitamins, carotenoids and coenzyme Q 10 . Vitamins are a type of trace organic regulatory substances that humans and animals must obtain from food in order to maintain normal physiological functions, and play an important role in the growth, metabolism, and development of the body; carotenoids are a type of important natural pigments In general, it can improve animal fecundity and immune function, and has various physiological functions such as anti-oxidation, coloring, and the ability to strengthen the connection and communication between cells and cell seams; coenzyme Q 10 It is a fat-soluble quinone compound, which can activate the nutrition of human cells and cell energy. It has the...
