Production and sensory characterization of a bitter peptide from beta-casein.

Peptide beta-casein fragment 193-209 (beta-CN f193-209) was isolated and purified for detailed sensory analysis in different matrices. The purity of the peptide was >98%. The mass of the peptide was 1882.51 Da, which coincided with the expected mass of beta-CN f193-209. N-Terminal analysis confirmed that the peptide started at residue 193 on the published… CONTINUE READING
