Abstract
A procedure was developed to coat peanuts with aqueous whey protein is olate (WPI) solutions based on increasing coating-solution viscosity. Oxygen uptake of WPI-coated nuts and uncoated nuts were compared. WPI coatings delayed oxygen uptake of dry roasted peanuts at intermediate (53%) and low (21%) storage relative humidity. They had similar result s at 29 degrees C and 37 degrees C. The effects of coating thickness a nd storage relative humidity indicate that the mechanism of protection of the coatings was through their oxygen barrier properties.
