Effects of Frozen Storage on the Ultrastructure of Bovine Muscle

摘要

ABSTRACTScanning electron microscopy (SEM) studies were carried out on bovine semitendinosus samples that were subjected both to long‐term frozen storage and to repeated freeze‐thaw cycles. Samples frozen at –18°C and stored up to 26 wk showed essentially no change in muscle ultrastructure. Samples frozen at liquid nitrogen temperature and stored at 2–3°C did show ice crystal damage within the muscle fiber. Repeated freeze‐thaw produced essentially no change in muscle ult
