摘要: Pairs of potato slices were blanched, soaked in a NaCl solution or water and fried. The originally adjoining faces the chips analysed for average L*a*b* color by digital photography image analysis. Stepwise increases blanching temperature (60, 65, 70, 75, 80 degrees C/5 min) gave rise to gradually darker above 65 C, total 9L* units (P = 0.001). Slices after 3% 5 min consistently paler 5L* 0.0054) than those only. Change concentration range 0.6-9% was found using one-tailed paired t-test, subsequent at 70 0.0125).
