Alterations in the connective tissue of pork liver during storage were examined histologically. The connective tissue outlining the lobule of pork liver was apparently unaltered during refrigerated storage (R‐S), but showed extensive crimping or waviness during freeze‐thaw (F‐T) cycling. Intralobular connective tissue (reticulin) disappeared during R‐S but was still visible after six F‐T cycles. The existence of a proteolytic enzyme active against Type III collagen at refrigerator temperatures but irreversibly inactivated by freezing was postulated.
