Embodiment 1

[0021] Taking 100g of water-soluble phytosterol oleate microcapsules as an example, the raw materials used and their proportioning ratio are as follows:

[0022]

[0023]

[0024] Its preparation method steps are as follows:

[0025] Step 1: Prepare the oil phase

[0026] Weigh 1.25g of monoglyceride and 35g of phytosterol oleate into a 200ml beaker, heat to 50-70°C to dissolve completely, and obtain the oil phase.

[0027] Step 2: Prepare the water phase

[0028] Take another 1000ml beaker, add 18.75g sucrose, dissolve it with 400ml purified water at 40-60°C, then add 3.75g sucrose ester of type SE-15, so that the mass ratio of glycerol monostearate to sucrose ester 1:3, the mass ratio of sucrose ester to sucrose is 1:5, stir to dissolve the sucrose ester, then add 30.94g of soybean protein isolate and 10.31g of maltodextrin in sequence, so that the mass ratio of soybean protein isolate to maltodextrin is about The ratio is 3:1, stirred at 40-60°C until uniformly mix...

Embodiment 2

[0036] Taking 100g of water-soluble phytosterol oleate microcapsules as an example, the raw materials used and their proportioning ratio are as follows:

[0037]

[0038]

[0039] Its preparation method is as follows:

[0040] In step 1, weigh 1.25 g of monoglyceride and 25 g of phytosterol oleate into a 200 ml beaker, heat to 50-70° C. to dissolve completely, and obtain an oil phase.

[0041] In step 2, 30.94 g of soybean protein isolate and 20.31 g of maltodextrin were added, so that the mass ratio of soybean protein isolate to maltodextrin was about 1.52:1. Other steps in this step were the same as in Example 1.

[0042] Other steps are identical with embodiment 1.

Embodiment 3

[0044] Taking 100g of water-soluble phytosterol oleate microcapsules as an example, the raw materials used and their proportioning ratio are as follows:

[0045]

[0046] Its preparation method is as follows:

[0047] In step 1, weigh 1.25 g of monoglyceride and 40 g of phytosterol oleate into a 200 ml beaker, heat to 50-70° C. to dissolve completely, and obtain an oil phase.

[0048] In step 2, 30.94 g of soybean protein isolate and 15.31 g of maltodextrin were added, and the mass ratio of soybean protein isolate to maltodextrin was about 2.02:1. Other steps in this step were the same as in Example 1.

[0049] Other steps are identical with embodiment 1.

Abstract

The invention belongs to the technical field of food and chemical industry and particularly relates to a water-soluble phytosterol unsaturated fatty acid microcapsule and preparation method of water-soluble phytosterol unsaturated fatty acid microcapsule. The microcapsule comprises 25 to 40 percent of phytosterol unsaturated fatty acid ester, 5 percent of emulsifying agents, 6.25 to 18.75 percent of sucrose and the balance wall materials, wherein the total quantity is 100 percent, the emulsifying agents are glycerin monostearate and sucrose ester, the mass ration of the glycerin monostearate to the sucrose ester is 1:(0.33-3), the ratio of the sucrose ester to the sucrose is 1:5, and the wall materials are dextrin and soy isolate protein. The water solubility of the phytosterol unsaturated fatty acid microcapsule is good, the phytosterol unsaturated fatty acid microcapsule can be mixed and dissolved with water-soluble matters, the application of the phytosterol ester to functional food, dairy products and beverages is widened, in addition, the preparation method disclosed by the invention is simple, the equipment requirement is low, and the preparation method is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical fields of food and chemical industry, and in particular relates to a method for preparing water-soluble phytosterol unsaturated fatty acid ester microcapsules prepared by embedding phytosterol unsaturated fatty acid ester into microcapsules. Background technique [0002] Phytosterol esters have the effect of significantly reducing blood LDL-cholesterol, and have good anti-oxidation and strong anti-inflammatory effects. functional food base. In September 2000, the U.S. Food and Drug Administration (FDA) approved that foods added with phytosterols and phytosterol esters can use the "healthy" label. Therefore, phytosterol esters are safe to use in food. [0003] However, phytosterol esters cannot be synthesized in the body and can only be ingested from diet or drugs. In addition, since phytosterol esters only have good fat solubility and are difficult to be miscible with water-soluble substances, this greatly limit...
