Paper Abstract

Second derivative Fourier-transform infrared [DR2-FTIR] spectra of β-lactoglobulin [RIG], serum albumin [BSA], and a-lactalbumin [aLA], three proteins found in bovine whey, are markedly different before and after thermal denaturation. In no case, however, do the heat-treated proteins unfold as completely as does alkaline-denatured RLG [1]. The spectra also suggest that, for RLG and BSA, formation of intermolecularly hydrogen-bonded (β-strands precedes the onset of heat-induced gelation.
