A fiber optic sensor was developed to measure the changes in diffuse reflectance of coagulating milk using infrared light at a wavelength of 950 nm. Reflectance profiles were measured during tests in which the coagulating temperature, pH, enzyme concentration, and milk fat content were controlled. All reflectance profiles showed an induction, sigmoidal, and logarithmic period. The diffuse reflectance was found to be a function of milk fat content and affected by milk pH, temperature, and enzyme concentration. |
