The experiment aimed to collect consistency coefficient data for dairy cream subjected to various heat treatments and subsequent temperature variations. Each sample of dairy cream with fat content of 10%, 20%, 30% 40%, 50% & 60% was subjected to different heat treatments i.e., 80°C/No hold, 85°C/No hold, 90°C/No hold & 95C°/No hold. The consistency of such heat-treated samples was evaluated at every 10°C upon cooling from 80°C or 70°C as the case may be till 10°C at 250 S-1 shear rate using rheometer. At a specified measurement temperature, the fat content of cream exhibited a notable (p<0.05) impact on the consistency coefficient. However, the heat treatment applied to the cream and their interaction displayed no significant (p>0.05) variation in the consistency coefficient. Both the fat content of the cream and the heat treatment demonstrated a positive correlation with the consistency coefficient, whereas the measurement temperature showed a negative correlation. These data are useful to dairy equipment designer for selection of proper sizing of equipment.
