The effect of thermal processing condition on the physicochemical and sensory characteristics of fermented sausages dried by Quick-Dry-Slice process®

Abstract

The effect of different thermal processing conditions just after fermentation on physicochemical parameters and sensory attributes of salami and chorizo slices dried by Quick-Dry-Slice process®, was evaluated. Meat and common additives were mixed, stuffed and fermented. Previous to drying the sausages were subjected to thermal treatment at 53°C at different exposure times (0, 50, 65, 80, 95 and 110min). Finally, the sausages were sliced and dried using QDS process®. Color, instrumental texture and sensory analysis were performed. Lightness (L*) after fermentation increased with thermal processing in both products while redness (a*) and yellowness (b*) decreased only in salami. Thermal treatment after fermentation increased the initial force (F0). Cooked appearance, cooked fat odor, cooked flavor and stringiness increased when the thermal processing time was increased. Thermal processing of salami and chorizo at 53°C for 50min and drying up to 30% of weight loss resulted in a similar product to that obtained without thermal processing.
