The effects of freezing and thawing (F‐T) and refrigerated storage (R‐S) on pork liver were examined. Intact cells were isolated from the tissue and analyzed for membrane integrity and the tissue extracts were analyzed for protein content. Significant (p < 0.05) differences were noted in the number of isolated intact cells and in tissue protein content between F‐T and R‐S or fresh livers. Differences in cell membrane integrity were also noted between fresh and R‐S livers. Repeated freezing and thawing appears to break down the liver structure differently than does refrigerated storage.
