A scanning electron microscopic, chemical and microbiological study of two types of chicken skin

Evaluation of several methods of fixing chicken skin for scanning electron microscopy (SEM) indicated standard chemical fixation using glutaraldehyde and osmium tetroxide followed by chemical dehydration with 2,2-dimethoxypropane to be the method of choice. SEM revealed that chicken skin has a convoluted surface. Two types of chicken skin, distinguishable on the basis of chemical composition and appearance were observed. Type I has a filamentous surface with 55% moisture and 25% fat, whereas Type II skin has a globular appearance, 52% fat and 33% moisture. The fatty acid profiles of Types I and II skin are the same. Bacteria have greater affinity for Type II than Type I skin. Attachment studies indicated that Salmonella typhimurium quickly attach to the skin surface and cannot be removed easily by washing with water or with water containing a surfactant. / Land and Food Systems, Faculty of / Graduate
