Measuring Water Holding Capacity—A Comparison between a Miniature near Infrared System and an Energy Dispersive X-Ray Scattering System

Abstract

The results presented here describe a comparative study on pork loins with drip loss varying from 0.25% w/w to 10.69% w/w. Thirty samples were measured using both near infrared (NIR) interactance and X-ray scattering. Partial least squares regression was used to build calibration models for each method. Results show that the correlation for the calibration model between NIR interactance and drip loss was R2 = 0.47 (leaving out three outliers) while that for X-ray and drip loss was R2 = 0.72 (leaving out three outliers).
