Preparation method of hippophae oil microcapsule

Abstract

The invention relates to a preparation method of a hippophae oil microcapsule product, which is a technology of forming a solid fine product by embedding hippophae oil in a fine and closed microcapsule by means of taking gelatin and Arabic gum as a film forming material. The method comprises the following steps: firstly, dissolving dried Arabic gum powder in distilled water, adding an appropriate amount of hippophae oil, and stirring and emulsifying to prepare an oil-in-water type emulsion; then, dissolving gelatin by distilled water; uniformly mixing with emulsified emulsion, and stirring, cooling, adding a curing agent, naturally settling and vacuum-freezing and drying and the like by a complex coacervation method to prepare the dried hippophae oil microcapsule product. The oil content of the hippophae oil microcapsule produced by the method reaches 40.1%, and has stability. The process is free from toxic and harmful auxiliary materials, organic solvents and bad smell. The product can be applied as a health-care product.

Description

Technical field

[0001] The invention belongs to the field of fine chemicals, and relates to a method for preparing seabuckthorn oil microcapsules, in particular to a method for preparing seabuckthorn oil microcapsules by using seabuckthorn oil as a main raw material through emulsification, encapsulation and solidification. technical background

[0002] Microencapsulation technology is a newly developed typical and unique fine chemical technology. It uses natural or synthetic polymer materials (commonly known as shell substances) to encapsulate solids or liquids (commonly known as core substances) into diameters ranging from a few microns to several microns. 100 micron tiny capsules. Upon exposure, core material is released due to wall rupture, dissolution, hydrolysis, or diffusion through the wall. The characteristic of microcapsule technology is that it can endow the inner package with new characteristics. Microcapsules have the following special functions: (1) prolong th...

Embodiment 1

[0019] First, place the gum arabic powder in a drying oven at 80°C for 1 hour to remove oxidase, add 3.0 g of dried gum arabic to 60 mL of distilled water (preheated at 37°C for 10 minutes) to dissolve it, and then add 6 g of sea buckthorn oil after dissolving, Stir with a mixer (the temperature is controlled at about 45°C), emulsify for 10 minutes, and observe under a microscope to make an oil-in-water emulsion. Then take 3.0g of gelatin, add 60mL of distilled water (preheated at 37°C for 10min) to dissolve it, add 3mL of glycerin after dissolving, then mix with the emulsified emulsion, keep the temperature of the glue at about 45°C, and keep stirring ( 1000r / min). Use newly prepared 5% HAc to adjust the pH value to 3.0. At this time, coagulation occurs (under the microscope, there is a round film layer outside the milk particles). After stirring for 10 minutes, add 210 mL of distilled water at 40°C, and stir to cool to 30°C. Add ice rapidly to lower the temperature below 10...

Use newly prepared 5% HAc to adjust the pH value to 3.5. At this time, coagulation occurs (under the microscope, there is a round film layer outside the milk particles). After stirring for 10 minutes, add 210 mL of distilled water at 40°C, and stir to cool to 35°C. Add ice rapidly to lower the temperature below 10...
