1. A method of generating and using time parameters to predict the cutting time of a milk coagulum comprising: (a) applying ultraviolet light with a peak intensity of about 280 nm to the milk coagulum from an ultraviolet light emitting diode source; (b) detecting light reflected from the milk coagulum in (a) with a fluorescence sensor, wherein detected light passes through both a high pass filter to remove light below 300 nm and a low pass filter to remove light above 475 nm; (c) measuring, by the fluorescence sensor, a fluorescence response change of said milk coagulum; (d) generating, by said controller, a first time parameter from said fluorescence response change; and (e) using, by said controller, said first time parameter and a cutting time prediction equation to predict the cutting time of said milk coagulum.
