Example Embodiment

[0032]Example 1:

[0033]Such asfigure 1 As shown, the vacuum emulsion can be used in Example 1 The vacuum emulsifier used in the emulsion includes a tank 1 and a can body disposed outside the can body mounting bracket 9. There are two hanging ears 10 arranged radially symmetrical along the can body. The top of the can body is provided with a liquid feed port 2, a vacuum port 3, and a vacuum pressure Table 7. The bottom of the can body is provided with a high shear tuber extract emulsifier 4 and the discharge port 5, and the lower portion of the tank sidewall is provided. 8. There is a gas separator in the tank.

[0034]The gas-solid separator includes a solid gas feed tube 601, an exhaust pipe 602, and a powder tube 603, and the solid gas feed tube are disposed at the bottom of the can body in the horizontal direction, and the other end projects from the can. In vitro and a solid gas feed port; the other end of the exhaust pipe extends in the top of the tank in the vertical direction and...

[0047]Example 3:

[0048]The vacuum emulsion tank structure used in Example 3 was the same as in Example 2. A method of preparing EPA microcapsules using the above vacuum emulsion can include the following steps:

[0049]S1: Water to the liquid surface in the vacuum emulsion is located above the solid gas feed port and the exit of the powder, and below the exhaust port, the wall material is blown into the tank in the tank with nitrogen gas feed tube to adjust the pH to 5.0. The shear emulsification are pre-emulsified; wherein the wall material is lactose, maltodextrin, and ocenic succinite, water is used as 4 times, citric acid. The concentration of gly fat in the pre-emulsion was 2 wt%, and the concentration of vitamin E was 4% by weight in the pre-emulsion;

[0050]S2: Add EPA to the premixture as an unsaturated fatty acid core material, and add citric acid monochid and vitamin E, after shearing emulsification, homogeneous, wherein the mass ratio of EPA and wall material is 50. : 50;

Abstract

The invention discloses a preparation method of unsaturated fatty acid microcapsules, which comprises the following steps: adding water into a vacuum emulsification tank provided with a gas-solid separator, blowing a wall material, an emulsifier and an antioxidant into the water in the vacuum emulsification tank by using inert gas through the gas-solid separator, and carrying out shear emulsification to obtain a pre-emulsified liquid; adding an unsaturated fatty acid core material into the pre-emulsified liquid, and sequentially performing shearing, emulsifying and homogenizing to obtain emulsified liquid; sterilizing the emulsified liquid; and carrying out spray drying on the sterilized emulsion, and sieving the obtained powder product to obtain the unsaturated fatty acid microcapsule. When the emulsified liquid is prepared, the vacuum emulsifying tank provided with the gas-solid separator is adopted for shearing and emulsifying, so that the utilization rate of raw materials is effectively improved; and the emulsified liquid is sterilized and then subjected to spray drying, so that the microcapsules are prevented from deteriorating under the action of microorganisms, and the shelf life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of microcapsule preparation, in particular to a preparation method of unsaturated fatty acid microcapsules. Background technique [0002] Unsaturated fatty acid is a kind of fatty acid that constitutes body fat. It is an indispensable fatty acid for the human body, such as DHA, ARA, CLA, GLA, ALA, EPA, DPA, etc. It has important nutritional value, so it is widely used in the food field. Because unsaturated fatty acids are easily oxidized, a large amount of hydroperoxides will be generated after oxidation, and then broken and decomposed to produce a series of volatile and non-volatile substances with short carbon chains, such as aldehydes, ketones, alcohols , acid substances, etc. Most of these substances have pungent odors and are harmful to the human body. Therefore, powder products embedded in microcapsules are generally added to food to avoid oxidation. [0003] Existing unsaturated fatty acid microcapsu...
