Notes:
Peanuts were exposed to low temperatures before they were dried to simulate temperature abuse. Samples were exposed to temperatures ranging from 0°C to −6°C. Visual examination of exposed samples revealed a glossy appearance around the edges and on the central surface of the cotyledons. A comparison of volatile profiles from exposed samples (0°C to −6°C) showed increased concentrations of acetaldehyde and ethanol with decreased temperatures. Conductivity was a measure of the electrolytes in the leachate from exposed samples and reflected the extent of membrane leakage. Concentrations of organic carbon and inorganic ions increased with decreased temperatures. Evidence of increased acetaldehyde and ethanol concentrations indicated anaerobic respiration was involved in quality deterioration of freeze damaged peanuts.
