Problems solved by technology

ARA oil is easily oxidized when exposed to air, and cannot withstand high temperature, so it is difficult to directly use it in infant formula under the condition of effectively maintaining its activity
If ARA oil is microencapsulated and then added to formula food, although it can effectively solve the defect of its easy oxidation and deactivation and maintain its activity in use, it also has the disadvantages of cumbersome addition and use process and difficulty in mixing uniformly. , and the energy consumption in the process of ARA oil microencapsulation is extremely high, which greatly increases the production cost

preparation example Construction

[0044] The preparation method of micron grade arachidonic acid emulsion, the steps are:

[0045] 1) Oil phase part: add arachidonic acid oil with a concentration higher than 40% into the oil phase emulsifier and antioxidant according to the above weight ratio, and heat the oil bath to 50-70°C to dissolve it to make an oil phase product A;

[0046] 2) Water phase part: Add water phase emulsifier, stabilizer and dispersant into water according to the above weight ratio, fully stir, heat to 60-90°C, keep for 20-60min, and make water phase product B;

[0047] 3) After the temperature of the water phase product B drops to 50-80°C, slowly add A to B, perform primary emulsification with a high-speed shearing machine, and obtain product C;

[0048] 4) pressure homogenize product C to obtain product D;

[0049] 5) The product D is sterilized and cooled to obtain the product E, which is an arachidonic acid emulsion.

[0050] In the preparation method of the emulsion, the sterilizatio...

Abstract

The invention discloses a micron-grade arachidonic acid emulsion liquid and a preparation method thereof. The emulsion liquid 1000g in total weight comprises 50g-150g of arachidonic acid, 10g-70g of oil-phase emulsifier, 0.1g-20g of antioxidant, 5g-40g of water-phase emulsifier, 60g-300g of thickened stabilizer, 10g-200g of dispersant and others of water. The emulsion liquid of the invention is O / W type, and the emulsion liquid with stable state and emulsified grain size of less than 1 micron is obtained mainly by the emulsifier and the thickened stabilizer of certain percentage go through the emulsification process with ARA oil and water. The task of the invention is to provide a formula for preparing an ARA emulsion liquid that can be dispersed in cold water and has good stability, and is stable against light, heat and oxygen, and the formula can be conveniently applied in the relevant industries of the drink industry, etc.

Description

technical field [0001] The invention relates to a micron-sized arachidonic acid emulsion and a preparation method thereof, in particular to the formulation, process and application of an arachidonic acid (ARA) emulsion that needs to be used in the food, medicine, health care products, and cosmetic industries . The product of the present invention is used as a nutrition fortifier. technical background [0002] Arachidonic acid is an omega-6 long-chain polyunsaturated fatty acid (PUFA) (5,8,11,14-eicosatetraenoic acid, C20:4). ARA is the most abundant C20PUFA in the human body. It mainly exists in organs, muscles and blood tissues. In addition to its main structural lipid role, it is also a number of bioactive substances derived from circulating eicosenoic acid. These active substances have Regulatory effects on lipoprotein metabolism, blood rheology, vascular elasticity, leukocyte function and platelet activation. However, ARA cannot be synthesized de novo in the human bod...
