Garlic oil microcapsule with shell made of soybean protein isolate and chitosan and preparation method and application thereof
The invention provides a garlic oil microcapsule with a shell made of soybean protein isolate and chitosan and a preparation method and application thereof. The preparation method includes making the soybean protein isolate, the chitosan and garlic oil into uniform emulsion; adjusting pH of the emulsion to 6.5, mixing to obtain microcapsule suspension, adjusting pH again to 6.0, adding glutamine transaminase, mixing to solidify the microcapsule, washing to collect wet microcapsule, and vacuum-freezing and drying to obtain the solid microcapsule, wherein mass ratio of the soybean protein isolate and the chitosan is 4:1 and mass ratio of a core and the shell is 1:1-1:4. The garlic oil microcapsule is obtained by electrostatic mutual attraction for the chitosan and the soybean protein isolate and embedding of the garlic oil, and accordingly pungent smell of the garlic oil can be covered, loss of diallyl sulfides in the garlic oil can also be avoided in food processing, and stability of the garlic oil is improved. Application of the garlic oil to the food industry is broadened.
