[0021] The present embodiment provides a preparation method of sea buckthorn essential oil microcapsules, which comprises:
[0022] Step S1: Mix the essential oil of sea buckthorn, the emulsifier solution and the coating liquid in which the coating material is dissolved, and emulsify and stir to obtain an emulsion.
[0023] Step S2: spray drying the emulsion obtained in step S1.
[0024] The following takes Tween 80 as an emulsifier, and takes hydroxypropyl-β-cyclodextrin as a coating material, and the embedding rate of the essential oil of sea buckthorn is an evaluation parameter, and each parameter in the preparation process is set and optimized:
[0025] 1. Recipe dosage:
[0026] 1.1 Dosage of hydroxypropyl-β-cyclodextrin:
[0027] The inventors selected the mass ratios of the microcapsule core material (sea buckthorn essential oil) and the coating wall material (hydroxypropyl-β-cyclodextrin) to be 1:2, 1:4, 1:6, 1:8, 1:2, respectively. 10 scale. Adopt the following pa...
Embodiment 1
[0076] The present embodiment provides a microcapsule of sea buckthorn essential oil, and its preparation method includes:
[0077] a. Weigh 48 g of hydroxypropyl-β-cyclodextrin, dissolve it with hot water at 70°C, and stir until it is evenly dispersed to obtain a coating solution;
[0078] b. dissolve and dissolve the emulsifier Tween-80 (5g) with 800mL of hot water to obtain an emulsifier solution;
[0079] c. Add 8g of sea buckthorn essential oil and emulsifier solution to the coating solution, and continue to stir rapidly until mixed. The obtained emulsion was poured into a high shear disperser and fully emulsified at 6000r / min for 50min, while maintaining the temperature at 70°C, and finally a white emulsion was obtained.
[0080] d. Drying by spray drying method, the air inlet temperature is 100°C, and the air outlet temperature is 190°C to obtain uniformly dispersed white powdery seabuckthorn oil microcapsules with a particle size of 400 μm.
[0081] The encapsulation...
Embodiment 2
[0083] The present embodiment provides a microcapsule of sea buckthorn essential oil, and its preparation method includes:
[0084] a. Weigh 80 g of hydroxypropyl-β-cyclodextrin, dissolve it with hot water at 75°C, and stir until the dispersion is uniform to obtain a coating solution;
[0085] b. dissolve and dissolve the emulsifier Tween-80 (5g) with 900mL of hot water to obtain an emulsifier solution;
[0086] c. Add 8g of sea buckthorn essential oil and emulsifier solution to the coating solution, and continue to stir rapidly until mixed. The obtained emulsion was poured into a high-shear disperser and fully emulsified for 60 min at a rotation speed of 5000 r / min, while maintaining the temperature at 75 °C, and finally a white emulsion was obtained.
[0087] d. Drying by spray drying method, the air inlet temperature is 110°C, and the air outlet temperature is 200°C to obtain uniformly dispersed white powdery seabuckthorn oil microcapsules with a particle size of 300 μm. ...
