Peanuts produced under the drought conditions of 1980 were marred by off-flavors when processed. Several phys ical characteri stics of these peanuts were noted to be related to these flavor problems. This paper deals with the investigation of these physical peculiarities using scanning electron microscopy. Major findings include previously unreported physical abnormalities such as: (1) tissue damage which appears as spotting on the outer surface of the cotyledon which is a result of cracking and fissuring; (2) tissue damage which appears as a narrow band along the inner face of the outer rounded surface and the flattened edge of the inner surface; and (3) a flattened inner surface of the cotyledon
