OXYGEN-UPTAKE MODEL FOR UNCOATED AND COATED PEANUTS

Mechanistic models for oxygen consumption due to lipid oxidation of pe anuts with and without whey protein coatings were developed. An appare nt zero/first order kinetics model was found to best describe the oxyg en uptake of uncoated peanuts in a closed system. Apparent oxygen perm eability of the coatings on the nut meat was found to be higher than o xygen permeability of cast films. Differences in film forming conditio ns between cast films and coatings were thought to be responsible for the apparent increase in oxygen permeability. (C) 1998 Elsevier Scienc e Limited.
