preparation example Construction

[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. ...

Abstract

The invention provides a fructus hippophae essential oil microcapsule and a preparation method thereof, and relates to the field of food or healthcare food. The preparation method of the fructus hippophae essential oil microcapsule comprises mixing fructus hippophae essential oil, an emulsifier solution and a cladding solution in which a cladding material is dissolved, and emulsifying and stirring, thus obtaining an emulsifying solution; carrying out spray drying on the emulsifying solution, wherein a mass ratio of the fructus hippophae essential oil to the cladding material is 1:(6 to 10). According to the preparation method provided by the invention, solid powder of a wall material having hydrophily is obtained by carrying out microencapsulation transformation on liquid-state fructus hippophae essential oil, and the defects that a grease part is oxidized in bare air and the storage is inconvenient are avoided by microencapsulated fructus hippophae essential oil; the fructus hippophaeessential oil microcapsule provided by the invention is strong in stability, and the fructus hippophae essential oil microcapsule not only can be used as an intermediate raw material for deep processing, but also can be directly used as nutritional healthcare products for development and utilization.

Description

technical field [0001] The invention relates to the field of food or health care products, in particular to a seabuckthorn essential oil microcapsule and a preparation method thereof. Background technique [0002] Seabuckthorn, the dried and ripe fruit of Hippophae rhamnoides L., a plant in the family Elaeaceae Deficiency of the spleen, lack of food, abdominal pain due to food accumulation, cough and phlegm, chest pain and heartache, blood stasis and amenorrhea, falling flutter and stasis and swelling embolism. Sea buckthorn oil is a precious natural oil extracted from the fruits and seeds of sea buckthorn. In addition to unsaturated fatty acids, sea buckthorn oil also contains more than 100 kinds of flavonoids, vitamins, phytosterols, trace elements and α-tocopherol. Biologically active substances have a wide range of medicinal value. [0003] However, the stability of the sea buckthorn oil is low, and it is easy to be oxidized and inconvenient to store during long-term s...
