Examples
Embodiment 1
[0060] After mixing 1% sodium alginate and 1% gelatin at a weight ratio of 1:1 to form a composite wall material solution, add the core material IDBN powder according to the core wall mass ratio of 1:3, mix and stir evenly, and then homogeneously emulsify for 5 minutes to obtain an emulsion, and then Put the emulsion at a feed temperature of 70°C, an inlet air temperature of 170°C, and an air flow rate of 30m 3 / h under the condition of spray-drying to powder, that is, IDBN microcapsules, the inclusion rate of 82.5%.
Embodiment 2
[0062] After mixing 1% sodium alginate and 2% gelatin at a weight ratio of 1:2 to form a composite wall material solution, add core material IDBN powder at a core-wall mass ratio of 1:1, mix and stir evenly, and homogeneously emulsify for 5 minutes to obtain an emulsion, then Put the emulsion at a feed temperature of 60°C, an inlet air temperature of 160°C, and an air flow rate of 20m 3 / h under the condition of spray-drying into powder, that is, IDBN microcapsules, the inclusion rate of 84.3%.
Embodiment 3
[0064] After mixing 1% sodium alginate and 2.5% gelatin at a weight ratio of 1:2.5 to form a composite wall material solution, add core material IDBN powder at a core-wall mass ratio of 1:2, mix and stir evenly, and then homogeneously emulsify for 5 minutes to obtain an emulsion. Then the emulsion is heated at a feed temperature of 70°C, an inlet air temperature of 170°C, and an air flow rate of 30m 3 / h under the condition of spray-drying to powder, that is, IDBN microcapsules, the inclusion rate of 86.3%.
