Embodiment 1-2

[0046] The influence of embodiment 1-2 emulsifier on microencapsulation efficiency

[0047] Weigh 49g of monoglyceride laurate, 5g of emulsifier, add 120g of water, stir at 60°C until completely dissolved to obtain solution A; then weigh 39.2g of soybean protein isolate, 156.8g of maltodextrin, add 630g of water, Stir at ℃ until completely dissolved to obtain solution B; then add solution A to solution B, and mechanically stir at a speed of 1500rpm for 15min to obtain an emulsion; The temperature is 60 DEG C, and the air inlet temperature is 150 DEG C), and the monoglyceride laurate microcapsule product is obtained.

[0048] Among them, the emulsifiers were soybean lecithin and sucrose ester (HLB value 15); the microencapsulation efficiency results are shown in Table 1.

Embodiment 3-7

[0051] Example 3-7 Effect of Wall Material Type and Proportion on Microencapsulation Efficiency

[0052] Weigh 61.25g of monoglyceride laurate, 5g of sucrose ester, add 130g of water, stir at 60°C until completely dissolved to obtain solution A; then weigh 183.75g of wall material, add 620g of water, stir at 60°C until completely dissolved Obtain solution B; then add solution A to solution B, and mechanically stir at a rotating speed of 1500rpm for 15min to obtain an emulsion; homogenize under 30MPa pressure (cycle 1 time), spray dry (feed temperature is 60°C, enter Wind temperature is 150 ℃), makes monolauric acid monoglyceride microcapsule product.

[0053] Among them, the wall material types, proportions and microencapsulation efficiency results are shown in Table 2.

[0055] serial number

Embodiment 8-12

[0056] The influence of embodiment 8-12 homogeneous pressure on microencapsulation efficiency

[0057] Weigh 71.5g of monoglyceride laurate and 3.5g of sucrose ester, add 150g of water, stir at 60°C until completely dissolved to obtain solution A; then weigh 100g of octenyl succinic acid starch ester, 150g of maltodextrin, add 525g Water, stirred at 60°C until completely dissolved to obtain solution B; then add solution A to solution B, and mechanically stir at a speed of 2000rpm for 20 minutes to obtain an emulsion; Drying (the feed temperature is 60° C., and the air inlet temperature is 150° C.) to obtain a monoglyceride laurate microcapsule product.

[0058] Among them, the pressure homogeneity is 20, 30, 40, 50 and 60MPa respectively; the results of microencapsulation efficiency are shown in Table 3. It can be seen from the table that when the pressure is higher than 30MPa, the improvement of microencapsulation efficiency is not obvious.

Abstract

The invention discloses a glycerol monolaurate microcapsule as well as a preparation method and an application of the glycerol monolaurate microcapsule. The preparation method comprises the following steps that: the glycerol monolaurate and emulsifying agents are dissolved into water being 60 to 70 DEG C to obtain solution A; wall materials are dissolved into the water being 60 to 70 DEG C to obtain solution B; the solution A and the solution B are mixed when the solution A and the solution B are still hot, stirring is carried out, and emulsion is obtained; and the emulsion is subjected to homogenizing and spray drying to obtain the glycerol monolaurate microcapsule, wherein the emulsifying agents are at least one kind of materials from sucrose ester, granulesten and fatty acid monoglyceride; and the wall materials are a mixture of maltodextrin and high-molecular compounds. The method provided by the invention is simple and practical, the controllability is strong, and the microencapsulation efficiency on core materials is higher; and the prepared glycerol monolaurate microcapsule has good flowability, dissolution dispersibility and mouth feeling, in addition, the anti-bacterium effect is not obviously reduced, and the glycerol monolaurate microcapsule can be applied to infant formula powder and realizes the effects of enhancing the immunity and resisting the infection.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a monoglyceride laurate microcapsule and a preparation method and application thereof. Background technique [0002] Glycerol Monolaurate (GML for short), the chemical name is 2,3-dihydroxypropanol dodecanoate, and its freezing point is 46-55°C. GML has poor water solubility and is almost insoluble in cold water, but can be dispersed and dissolved in hot water. The molecular structure of GML contains hydrophilic groups and lipophilic groups. It is a lipophilic non-ionic surfactant with an HLB value between 4 and 6. It has excellent emulsifying and antibacterial functions. It was launched in my country in 2005. Approved for use in various types of food. [0003] In the early stages of baby growth, breast milk can not only provide the nutrients needed for the baby's growth and development, but also contain some anti-bacterial and anti-viral ingredients. Studies have shown that these...
