SUMMARY Aging of muscle had previously been shown in our laboratory to increase the propensity of properly treated muscle cell segments to empty on extraction with water. It has been suggested that this emptying is caused by breakdown of a cytoskeleton, and, further, that this cytoskeleton is stabilized by flavin adenine dinucleotide (FAD). Due to the possible relationship of cytoskeletal breakdown to quality changes in meat post‐mortem, the role of FAD in the preservation of cytoskeletal structure in chicken breast muscle was studied. No significant differences in FAD decomposition or extraction were found between samples handled in a manner such as to produce very large differences in the extent of emptying, the measure of cytoskeletal breakdown. Similarly, adding FAD to suspensions of muscle cell segments could not inhibit emptying under conditions where the supernatant fraction of a muscle homogenate could. It was concluded that FAD plays no role in the stabilization of the cytoskeleton of chicken breast muscle.
