Abstract
Measurement of potato chip color is extremely important to the potato processing industry. A procedure is described whereby finished chip samples were utilized for correlation of one spectrophotometric chip color measurement system with another. Calibration, standardization, sample preparation, randomization and prediction equation development procedures are described.

La medición de la coloración de las papas fritas a la inglesa es extremadamente importante para la industria de procesamiento de la papa. Se describe un procedimiento donde fueron utilizadas muestras de papas fritas a la inglesa para correlacionar un sistema de medición expectrofotométrica del color de las papas procesadas con otro sistema. Se describen los procedimientos de calibración, estandarización, preparatión de las muestras y los procedimientos de muestreo al azar. Una ecuación de pronóstico relaciona los dos sistemas.
