Microencapsulation of spices with Methylcellulose/alginate/methylcellulose and the components stability during storage

Abstract

Composite core material (2-Phenethyl alcohol/Cinnamaldehyde/β-ionone) microcapsules were prepared by spray drying using amphiphilic methylcellulose (MC) as the emulsifier and interior wall material, alginate (ALG)/methylcellulose (MC) as the composite external wall materials to embed core materials and improve the stability of core materials. The release of core material of the microcapsules and composition changes of core material during storage and the protective effect of microencapsulation on core materials was also analyzed.
