چکیده انگلیسی
The effect of aperture size on instrumental pork color measurements was studied. Pork longissimus chops (n = 30) were cut, aerobically packaged, and allowed to bloom overnight. Chops were measured once with each of four aperture ports (4.45, 2.54, 1.27, and 0.64 cm diameter) on a HunterLab LabScan. Reflectance values measured with smaller aperture sizes were reduced (P < 0.05) for most visual wavelengths (10 nm intervals), and the percent reduction was greatest in the range of the longer, redder wavelengths. Values for Lâ, aâ, bâ, and saturation index were reduced (P < 0.05) with decreasing aperture size under illuminants A, C, and D65. Using illuminant A, hue angle increased (P < 0.05) as aperture size decreased. For illuminants C and D65, hue angles were similar (P > 0.05) for the three largest aperture sizes, but negative aâ values found with the smallest aperture size skewed the hue angle data.
