Abstract:
The influence of thermomechanical treatment (temperature 60 C -- 100 C and shear rate 0.05 s1 -- 50 s1) on the denaturation and aggregation of beta-Lactoglobulin at high concentrations (50 % -- 70 %) was investigated. While denaturation and aggregation reaction rate decreased at higher concentrations, a combination of heat and mechanical treatment resulted in an increase in reaction rates and consequently, in higher degrees of nondisulfide covalent bond aggregation. The kinetic parameters were d...     »
