Embodiment 1

[0043] A kind of preparation method of double emulsion, concrete steps are as follows:

[0044] 1. Dissolve 0.8g of gelatin in 10mL of deionized water, soak for 45 minutes, stir and dissolve in a water bath at 70°C as the inner water phase W 1 , and set aside after cooling. At 60° C., 4% (w / v) polyglycerol ricinoleate and 10 mL of soybean oil were mixed and stirred for 20 min, and oil phase O was obtained after the polyglycerol ricinoleate was completely dissolved. Water Phase W 1 The oil phase O is sheared according to the volume ratio of 1:4, and the shearing condition is 15000r / min, 7min. After shearing, the primary emulsion W 1 / O.

[0045] 2. Add 1.5g of sodium caseinate into 50mL of deionized water, and stir for 12 hours to form a solution as the external water phase W 2 .

[0046] 3. Take 1mL of the primary emulsion and slowly add 2.4mL of the external water phase W at a shear rate of 13000r / min 2 , that is, shearing for 7 minutes according to the volume ratio of...

[0050] A kind of preparation method of double emulsion, concrete steps are as follows:

[0051] 1. Dissolve 1g of gelatin in 10mL of deionized water, soak for 45min, stir and dissolve in a water bath at 70°C as the inner water phase W 1 , and set aside after cooling. At 55° C., 5% (w / v) polyglycerol ricinoleate and 10 mL of soybean oil were mixed and stirred for 30 min, and oil phase O was obtained after the surfactant was completely dissolved. Water Phase W 1 The oil phase O was sheared according to the volume ratio of 1:4, and the shearing condition was 14000r / min, 7min. After shearing, the primary emulsion W 1 / O.

[0052] 2. Add 1.5g of sodium caseinate into 50mL of deionized water, and stir for 12 hours to form a solution as the external water phase W 2 .

[0053] 3. Take 2mL of the primary emulsion and slowly add 3mL of the external water phase W at a shear rate of 10000r / min 2 , that is, shearing for 10 minutes according to the volume ratio of 2:3 to obtain a sta...

Abstract

The invention discloses a preparation method of a high-stability dual emulsion and application of the high-stability dual emulsion to astaxanthin carrying. A solution containing gel substances is used as an internal water phase W1, glyceride containing polyglycerol ricinoleate (PGPR) is used as an oil phase O, and a W1 / O emulsion is obtained under the condition of shear emulsification. A water phase W2 dissolved with sodium caseinate is added into the preliminarily obtained W1 / O emulsion, high shear treatment is performed to obtain a W1 / O / W2 dual emulsion, a gel solution is added to the outermost layer of the formed dual emulsion, and shear treatment is performed again to obtain the final high-stability dual emulsion. According to the invention, the dual emulsion has better stability, so that the dual emulsion can be more widely applied to the fields of food, medicines, cosmetics and the like.

Description

technical field [0001] The invention relates to a preparation method of a double emulsion. Specifically, it is a method for preparing a highly stable water-in-oil-in-water (W / O / W) double emulsion used for astaxanthin delivery, which belongs to the technical field of food preparation. Background technique [0002] Double emulsion, also known as multiple emulsion, is a relatively complex dispersion system consisting of three phases. The common ones are hydrophilic W / O / W emulsion and hydrophobic O / W / O emulsion. Double emulsions have many advantages that make them potentially valuable in areas such as food. Including: (1) Encapsulate sensitive substances such as spices, pigments, vitamins, nutrients, probiotics, enzymes, etc., which can use their hydrophilic or hydrophobic capabilities to mask odors, improve their stability, increase their activity, and be targeted (2) Compared with the traditional simple O / W emulsion, the fat content in the W / O / W emulsion is reduced, which c...
