Cross-linking of proteins has been exploited by the food industry to change food texture and functionality but the effects of these manipulations on food allergenicity still remain unclear. To model the safety assessment of these food biopolymers, we created cross-linked bovine β-lactoglobulin (CL-BLG) by laccase treatment. The purpose of the present study(More)
Non-covalent interactions between β-lactoglobulin (BLG) and polyphenol extracts of teas, coffee and cocoa were studied by fluorescence and CD spectroscopy at pH values of the gastrointestinal tract (GIT). The biological implications of non-covalent binding of polyphenols to BLG were investigated by in vitro pepsin and pancreatin digestibility assay and ABTS(More)
Polyphenols, the potent plant secondary metabolites, have beneficial effects on human health, but the mechanism(s) by which these effects are exerted is not well understood. Here, we present the detailed analysis of the interactions between the major green tea catechin, epigallo-catechin 3-gallate (EGCG), and the major dietary protein and allergen,(More)
BACKGROUND The major whey protein β-lactoglobulin (BLG) has been widely studied for its functional properties. The aim of this study was to develop an efficient, inexpensive and rapid one-step method for the isolation and purification of BLG while preserving its native structure. RESULTS BLG was purified from defatted whey obtained from raw cow's milk by(More)
SCOPE The aim of this work was to investigate the effects of high-intensity ultrasound (sonication), on the structure and allergenicity of the major cow's milk allergen, beta-lactoglobulin (BLG). METHODS AND RESULTS Structural changes upon sonication of BLG were monitored by circular dichroism spectroscopy, tryptophan emission fluorescence, hydrophobic(More)
