Texture changes in dry-cured ham pieces by mild thermal treatments at the end of the drying process

Abstract

The present study evaluated the effects of mild thermal treatments at the end of the drying process on physicochemical characteristics and instrumental and sensory texture in dry-cured ham. Experiment 1: effect of thermal treatments (4–46°C) for 4h and 24h. Experiment 2: time effect (4–168h) of thermal treatments at 30°C and 36°C. Both experiments were done on small dry-cured ham dices. Experiment 3: time effect (4–168h) of thermal treatment at 30°C on both instrumental and sensory texture of 4-cm-thick sections of dry-cured ham. The thermal treatment at 30°C for 168h on both dry-cured ham muscle dices (20mm×20mm×15mm) and dry-cured ham sections (4cmthick) decreased softness, adhesiveness and pastiness in BF muscle, without increasing hardness in SM muscle or affecting moisture, aw and proteolysis index.
