Abstract
Development of lipid oxidation in casein-stabilized emulsion-gels prepared using microbial transglutaminase was investigated. The oxidative stability of emulsion-gels was assessed based on measurement of the amount of lipid hydroperoxide, hexanal, and 1-octen-3-ol. Profiles of lipid hydroperoxide showed that formation of lipid hydroperoxide was reduced in emulsion-gels, compared with emulsions, regardless of the storage temperature. Quantitative analysis of hexanal and 1-octen-3-ol showed no significant (p>0.05) difference between oxidative stabilities of emulsion-gels and emulsions. The storage temperature did not affect formation patterns of hydroperoxide, hexanal, and 1-octen-3-ol. Transglutaminase can be a useful tool for retardation of lipid oxidation based on formation of emulsion-gels.
