Summary, etc. The quantitative data on hysteresis size in heat treated milk are scarce mainly because of the lack of suitable methods to quantify the degree of changes in it. The kinetic reactions of heat treated milk were studied at processing of milk on the range of 60-80°C for holding time 5-30 min. The hysteresis loops were determined from acid-base potentiometric titration. The values of the hysteresis size were increased with increasing heat treatment or holding times. Kinetic parameters i.e.; the velocity constants (k), the decimal reduction times value (DS), the activation energy (Ea), the thermal coefficient values (Z-value) and temperature coefficient value (Q10) were calculated. The k and Z values were increase with increasing of heat treatment. While, DS and Q10-values illustrated decrease trend with increasing of heat temperature up to 80°C. The mean values of K, DS, Z and Q10-values values were 0.239 min"\ 12.50 min, 34.71°C and 1.94 during complete temperature range, respectively. The activation energy required to complete the loss reaction of hysteresis size in standardized buffalo's milk samples after heat treatment under the studied temperature range was 64.834 KJ/mol.K. In all heat treatment milk samples, the reaction could be described as first order reaction kinetics during studied temperature range. Key words: Physico-chemical parameters, Hysteresis, Potentiometric Acid-base titration, Heat treatments, Kinetic reaction.
