Abstract

Monitoring the culture of skim milk and determining coagulum cutting time are critical steps in the production of cottage cheese. Changes in reflectance and optical consistency profiles of the culture of skim milk at four different protein levels were tested using a fiber optic probe system. The culture of skim milk was monitored by measuring reflectance and optical consistency profiles. It was found that the most responsive light wavelengths were 900 and 420 nm for reflectance and optical consistency, respectively. Protein was found to have a significant linear effect on optical consistency. Coagulum cutting time can be correlated with process variables to determine prediction cutting time models.
