Abstract:
Microcapsules containing flavonoids compounds were prepared by piercing method with sodium alginate as shell material. Through the single factor and orthogonal test to determine flavonoids microcapsule preparation influence of the main factors. The best technological conditions were sodium alginate concentration of 1.4%, core/wall material ratio of 1:1, CaCl2 concentration of 1.4%, and monoglyceride/core ratio of 0.2 g/g. Under these conditions, encapsulation efficiency reached 92.59%.Microcapsule products structure was hard and round with no trailing phenomenon.
