APPLICATION NOTE STANDARDIZATION OF CHEESE MILK USING AN IN-LINE DAIRY ANALYZER In-line analysis of cheese milk for standardization of fat and protein levels to maintain fat/protein ratio. In the production of various cheese such as cheddars, mozzarella, Monterey Jack etc., the level of fat in the milk is adjusted to maintain a certain fat to protein ratio. This is done by skimming or partially skimming the fat from the milk, then adding it back in at a certain level to control this ratio. The range of fat varies with the product i.e., “no”-fat cheese, low fat cheese, regular fat cheese. The fat to protein ratio is different for each type and must be maintained. The coagulation to produce the cheese curd takes place in a vat filled with the cheese milk. The typical time to fill a vat is approximately 20 minutes. Production managers and operators must maintain the fat to protein ratio for each cheese types. This could be challenging since production facilities typically produce more than one cheese type which can change throughout the shift. Samples are typically collected and tested manually during start-up and throughout the production run to maintain consistency. This is critical since a vat is filled in a short time and out of specification milk can upset the production. The overall challenge is to: • Optimize the protein/fat ratio for cheese milk • Maintain complete control of the protein and fat blending ProSpect real time in-line ana

CHEESE MILK STANDARDIZATION PROCESS BENEFITS Solution APPLICATION NOTE CHEESE MILK CALIBRATION STATISTICS The ProSpect In-line Process NIR provides accurate, rapid, continuous analysis of Fat and Protein in the cheese milk. From these results the Fat:Protein ratio are calculated and displayed. Total Solids These results can be output to a plant control system or standardizing system to automatically control the process: UF process, fat blending, protein blending. • R2 = The correlation between the lab reference value and the ProSpect predicted value • SECV = Standard Error of Cross Validation....
