Effect of microencapsulation on chemical composition and antioxidant activity of cumin and fennel essential oils.

摘要

ABSTRACT This study aimed to evaluate the effect of some carrier materials, i.e. alginate, chitosan, carrageenan and carboxy methyl cellulose (CMC) on the chemical composition and antioxidant activity of cumin and fennel essential oils (EOs). GC and GC-MS analysis identified 22 compounds, representing 86.77% of the total cumin EO, and 16 compounds, representing 97.10 % of the total fennel EO. The major compounds in cumin and fennel EOs were P-mentha1, 4-diene-7-al, cumin aldehyde, P-mentha-1, 3.
