Effect of Hot Water Immersion on Sensory Properties of Non-Refrigerated Peanuts¹

Sensory properties of Fla Early Bunch and NC 7 peanuts immersed in hot water at 79 C for 90 sec and subjected to non-refrigerated storage were evaluated. Sensory scores were lower for immersed peanuts than the non-immersed peanuts, however the attributes for the immersed peanuts were not scored lower than borderline throughout storage. Flavor scores for both cultivars ranged between 6 for slightly good and 7 for moderately good. Significant cultivar differences were observed for color at the initial month and flavor at 2, 5, and 8 mo. NC 7 peanuts had significantly higher flavor sensory scores than the Fla Early Bunch nuts. Duo trio tests showed that panelists detected significant differences between non-immersed and immersed peanuts at the eighth month of storage.
