Predicting cutting and clotting time of coagulating goat's milk using diffuse reflectance: effect of pH, temperature and enzyme concentration
M Castillo, FA Payne, CL Hicks, MB Lopez - International Dairy Journal, 2000 - Elsevier
A diffuse reflectance sensor, which used optical fibres and near-infrared radiation (NIR) at
880nm, was used to monitor goat's milk coagulation. A randomised block design replicated
three times was utilized to test the effects of pH, temperature and enzyme concentration on
diffuse reflectance parameters. Milk pH was adjusted to three levels (5.5, 6.0 and 6.5) and
coagulated at three different temperatures (28, 32 and 36° C), using three enzyme
concentrations (0.020, 0.035 and 0.050 mLkg− 1 of milk). A linear cutting time prediction …
