The oxidation of methyl linoleate was inhibited by β-carotene, lutein and bixin in a dose-dependent manner. Lutein and zeaxanthin suppressed the hydroperoxide formation more efficiently than β-carotene and bixin at 41.7×10-6mol/L. Lutein inhibited the oxidation of methyl linoleate as efficiently as zeaxanthin.

Kefir manufactured by goat milk powder had significantly higher medium chain fatty acid than by fresh goat milk. This could be explained by the higher fat content in goat milk powder. Addition of growth promoters decreased the level of medium chain fatty acids. By comparing both growth promoters, adding peptide had significantly lower caproic acid and caprylic acid than isomaltooligosaccharide did.
