Abstract
The physicochemical properties of heat-induced ovalbumin (OVA) gels co ntaining fatty acid salts (FAS) were investigated. Water-holding abili ty and transparency markedly increased in the presence of Sodium capra te or sodium laurate. Ar 9% of the protein concentration transparent a nd hard gels formed; at 7%, transparent and soft gels formed. Scanning electron microscopy showed that the transparent gels had a more homog eneous structure than turbid gels without FAS. Differential scanning c alorimetry indicated that denaturation temperature of OVA was decrease d and the peaks became broader after addition of FAS.
