preparation example Construction

[0017] .A preparation method of DHA and ARA emulsion, comprising the following processes successively: emulsion preparation:

[0018] The emulsion preparation process includes the following three parts: A, B, and C:

[0019] A. Prepare the water phase in the shear emulsification tank of the emulsification equipment: add pure water, heat and keep it warm to 35-65°C, turn on the shear emulsification stirring device, add sodium ascorbate in an amount of 0.1-4.2kg, and then add the emulsifier: The added amount of sodium starch octenyl succinate is 1.6-28 kg, the added amount of sodium caseinate is 0.2-3.5 kg, the added amount of gum arabic is 0.96-16.8 kg, the added amount of concentrated milk protein is 1.6-28.0 kg, the above emulsifier Just add one kind, shearing: Use the shearing head to stir the material at high speed, and shear for 3 to 10 minutes until fully dissolved;

[0020] B. Prepare the oil phase in the oil tank of the emulsification equipment: add vegetable oil in ...

Embodiment 1

[0027] Taking the production of one ton of milk powder as an example, the ingredients are as follows:

[0028] 1. Amount of fortifier (DHA oil): 0.15~3.0kg.

[0029] 2. Amount of enhancer (ARA grease): 0.15~3.0kg.

[0030] 3. Addition amount of emulsifier (starch sodium octenyl succinate): 1.6~28.0kg.

[0031] 4. Addition amount of antioxidant (ascorbyl palmitate): ≤0.2g / kg.

[0032] 5. Antioxidant (sodium ascorbate) dosage: 0.26~4.2kg.

[0033] 6. Antioxidant (vitamin E) addition amount: Add appropriate amount according to production needs.

[0034] 7. Addition amount of vegetable oil (walnut oil, soybean oil, corn oil, palm oil): 0.5~8.0kg.

[0035] 8. Optimum ratio: By comparing the oven method and the water bath method, it is determined that starch sodium octenyl succinate: DHA and ARA oil = 2: 1, the emulsification effect is the best.

Embodiment 2

[0037] Taking the production of one ton of milk powder as an example, the ingredients are as follows:

[0038] 1. Amount of fortifier (DHA oil): 0.15~3.0kg.

[0039] 2. Amount of enhancer (ARA grease): 0.15~3.0kg.

[0040] 3. Addition amount of emulsifier (sodium caseinate): 0.2~3.5kg.

[0041] 4. Addition amount of antioxidant (ascorbyl palmitate): ≤0.2g / kg.

[0042] 5. Antioxidant (sodium ascorbate) dosage: 0.1~1.2kg.

[0043] 6. Antioxidant (vitamin E) addition amount: Add appropriate amount according to production needs.

[0044] 7. Addition amount of vegetable oil (walnut oil, soybean oil, corn oil, palm oil): 0.5~8.0kg.

[0045] 8. Optimum ratio: By comparing the oven method and the water bath method, it is determined that sodium caseinate: DHA and ARA oil = 1:4, and the emulsification effect is the best.

Abstract

The invention provides a method for preparing a docosahexaenoic acid (DHA) and eicosatetraenoic acid (ARA) emulsion. The method comprises the following steps of: preparing an aqueous phase solution and preparing an oil phase solution. An oil phase is dissolved in an aqueous phase to prepare the emulsion; the process for preparing the emulsion comprises the following steps of: dissolving an emulsifying agent, dissolving an ARA and DHA oiling agent, and mixing the emulsifying agent and the ARA and DHA oiling agent; and the process for emulsifying an interfacial film comprises the following steps of: shearing and emulsifying materials, and homogenizing circularly to obtain the DHA and ARA oiling agent emulsion. Production equipment is simple, and the method is suitable for large-scale and continuous production, is favorable for popularization and application and is suitable for production enterprises of formula milk powder and the like. The method has the advantages that 1, the stability is high; 2, the trophism is high; 3, according to the originality, the method is initiative; and 4, according to the novelty, the emulsion serving as a third formulation is invented.

Description

Technical field: [0001] The invention relates to a preparation method of DHA and ARA emulsion. Background technique: [0002] DHA, the scientific name docosahexaenoic acid, commonly known as brain gold, is a straight-chain fatty acid with 22 carbon atoms and 6 double bonds, and is an important member of the Omega-3 unsaturated fatty acid family. DHA is a major element for the growth and maintenance of nervous system cells, and an important component of the brain and retina. Essential for intellectual and visual development. Its structural formula is as follows: [0003] [0004] ARA: The scientific name is eicosatetraenoic acid, also known as arachidonic acid, which contains four carbon-carbon double bonds and one carbon-oxygen double bond. It belongs to the Omega-6 long-chain polyunsaturated fatty acid. Fatty acid--linoleic acid is converted into, not an essential fatty acid, which plays an important role in the development of the brain and nervous system. Its struct...
