Abstract

The effects of reducing pork fat level from 30 to 25 and 20% by partially substituting pork fat with 1 and 2% apple pomace fiber were investigated based on the evaluation of physicochemical properties and textural properties of uncured, reduced-fat chicken sausages. Increased fat level resulted in decreased moisture content, cooking loss, total expressible fluid separation, fat separation, and yellowness of uncured, reduced-fat chicken sausages, whereas, an increase in fat content, caloric energy, pH, lightness, redness, hardness, cohesiveness, gumminess, and chewiness was observed. The results showed that uncured, reduced-fat chicken sausage samples with increased apple pomace fiber level had lower cooking loss, total expressible fluid separation, fat separation, pH, and redness. The results from this study show that inclusion of apple pomace fiber in the formulation will successfully reduce fat content in emulsion sausages, while improving quality characteristics relative to regular-fat (30%) control.
