Example Embodiment

[0032] Example 1

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

[0034] Add 30kg of gelatin (isoelectric point 4.8), 1kg of sodium carbonate and 45kg of maltodextrin into an emulsifying pot that has already placed 100kg of purified water, and stir and dissolve into a uniform wall material aqueous solution at 50°C.

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

[0038] Example 2

[0039] Add 0.2kg ascorbyl palmitate, 0.4kg carnosic acid, 1.6kg phosphatidylcholine and 2kg peanut oil into the oil dissolving pot, vacuumize for three times, stir at 45℃ for 30min, then add 10kg vitamin A acetate The crystals (2.812 million IU / g) continue to stir until the vitamin A acetate crystals dissolve and form a uniform vitamin A-containing core material.

[0040] 15kg of gelatin (isoelectric point 4.8), 0.4kg of sodium carbonate and 72kg of glucose were added to an emulsifying pot that had already placed 100kg of purified water, and stirred at 50°C to dissolve into 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 again under high pressure. The homogenization pressure is 25MPa, and the pH value is between 6.0~ 7.5 and oil droplet size D 50 Vitamin A emulsion between ...

Example Embodiment

[0044] Example 3

[0045] Add 2kg of ascorbyl palmitate, 4kg of carnosic acid, 8kg of glycerophosphocholine and 12kg of soybean oil into the melting pot, vacuumize and add nitrogen three times, stir at 60℃ for 30min, and then add 32kg of vitamin A acetate crystals ( 2.705 million IU / g) continue to stir until the vitamin A acetate crystals dissolve and form a uniform vitamin A-containing core material.

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

[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 again under high pressure at a homogenizing pressure of 25MPa, and the pH value is between 6.0~ 7.5 and oil droplet size D 50 Vitamin A emulsion be...

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...
