Answer:
Lysosome
Explanation:
Freezer burn occurs due to the sublimation of ice in unprotected meat rich in muscles during long-frozen storage. It appears after thawing. The ice crystals rupture the lysosomes which in turn contain hydrolyzing enzymes.
Leakage of the hydrolytic lysosomal enzyme causes freezer burn and affects the appearance of the frozen meat. The hydrolytic enzymes of lysosomes partially digest the cells which in turn impart bad flavor to the stored food.
