Embodiment 1

[0033]Add 1kg of ascorbyl palmitate, 1.2kg of carnosic acid, 3kg of acetylcholine and 4kg of palm oil into the oil-dissolving pot, vacuumize and replenish nitrogen three times, stir at 50°C for 30min, and then add 20kg of vitamin A acetate crystals (2.812 million IU / g) continue stirring until vitamin A acetate crystals dissolve, forming a uniform core material containing vitamin A.

[0034] Add 30kg of gelatin (isoelectric point 4.8), 1kg of sodium carbonate and 45kg of maltodextrin into the emulsification pot with 100kg of purified water, stir and dissolve at 50°C to form a uniform wall material aqueous solution.

[0035] Slowly add the core material into the high-speed shear (line speed 6.0m / s, the same below) wall material aqueous solution. After adding the core material, continue shearing and stirring at 50°C for 20 minutes, and then homogenize under high pressure once. The mass pressure is 25MPa, and the pH value is between 6.0 and 7.5 and the oil droplet size D 50 Vitam...

Embodiment 2

[0039] Add 0.2kg of ascorbyl palmitate, 0.4kg of carnosic acid, 1.6kg of phosphatidylcholine and 2kg of peanut oil into the oil-dissolving pot, evacuate and replenish nitrogen three times, stir at 45°C for 30 minutes, and then add 10kg of vitamin A acetate The crystals (2,812,000 IU / g) were continuously stirred until the vitamin A acetate crystals were dissolved to form a uniform vitamin A-containing core material.

[0040] Add 15kg of gelatin (isoelectric point 4.8), 0.4kg of sodium carbonate and 72kg of glucose into an emulsification pot with 100kg of purified water, stir and dissolve at 50°C to form a uniform wall material aqueous solution.

[0041] Slowly add the core material to the high-speed shearing wall material aqueous solution. After adding the core material, continue to shear and stir at 50°C for 20 minutes, and then homogenize under high pressure at 25 MPa to obtain a pH value between 6.0 and Between 7.5 and oil droplet size D 50 Vitamin A emulsion between 0.8 ~ ...

Embodiment 3

[0045] 2kg of ascorbyl palmitate, 4kg of carnosic acid, 8kg of glycerophosphocholine and 12kg of soybean oil were added to the oil-dissolving pot, vacuumed three times to replenish nitrogen, stirred at 60°C for 30min, and then added 32kg of vitamin A acetate crystals ( 2,705,000 IU / g) continue to stir until vitamin A acetate crystals dissolve, forming a uniform core material containing vitamin A.

[0046] Add 40kg of gelatin (isoelectric point 4.8), 1.3kg of choline and 5kg of glucose into an emulsification pot with 120kg of purified water, stir and dissolve at 50°C to form a uniform wall material aqueous solution.

[0047] Slowly add the core material to the high-speed shearing wall material aqueous solution. After adding the core material, continue to shear and stir at 50°C for 20 minutes, and then homogenize under high pressure at 25 MPa to obtain a pH value between 6.0 and Between 7.5 and oil droplet size D 50 Vitamin A emulsion between 0.8 ~ 1.2um.

Abstract

The invention belongs to the field of vitamins, and discloses a vitamin A microcapsule and a preparation method and applications thereof. The preparation method of the vitamin A microcapsule comprisesthe following steps: stirring palmitate ascorbate, carnosic acid, choline and / or choline derivatives and optional grease at 45-60 DEG C for at least 5 minutes, then adding vitamin A, and performing stirring until the vitamin A dissolves to obtain a core material; dissolving a wall material in water, wherein the wall material is a mixture of a protein wall material and a carbohydrate wall material, and the isoelectric point of the gelatin is 4.5-5.6 when the protein wall material contains gelatin so as to obtain a wall material aqueous solution; and mixing and emulsifying the core material andthe wall material aqueous solution to form vitamin A emulsion, wherein the pH value of the vitamin A emulsion is controlled to be 6.0-7.5, and the particle diameter D50 of the oil drop is controlledto be 0.8-1.2 microns, and then performing spray drying on the vitamin A emulsion to obtain the vitamin A microcapsule. The vitamin A microcapsule obtained by the method provided by the invention hashigh stability in feeds and feed premixes.

Description

technical field [0001] The invention belongs to the field of vitamins, and in particular relates to a vitamin A microcapsule and its preparation method and application. Background technique [0002] Vitamin A is one of the essential nutrients for the human body. Vitamin A exists only in animal foods, such as the liver of mammals and fish, and vitamin A has not been found in plant tissues. Lack of vitamin A can lead to various diseases in vision, taste, growth and development, skin and so on. [0003] Vitamin A is an oil-soluble unsaturated ester, which is easily oxidized and unstable under light and oxygen conditions, so its application range is limited. Microencapsulating it into solid powder can expand its application range. Especially in the field of food nutrition fortifiers, the demand for vitamin A microcapsule products with good water solubility and stability is increasing. [0004] Microencapsulation technology refers to the technology of embedding solids, liquids...
