This paper presents the study on determination of the effect of pullulan on the quality of low-fat homogenized scalded sausages stored in vacuum packages at 4 ± 1°C for 21 days. Control sausage (PC) ...contained 20% of pork jowl in recipe composition. In sausages P1, P2 and P3, respectively, 1/4, 1/2 and 3/4 of jowl content was substituted with pullulan. The chemical composition was determined, the color and texture were measured and sensory evaluation was performed in sausages. Microbiological analyses were performed in sausages after 0, 3, 7, 10, 14 and 21 days of storage. It was found that the use of pullulan did not lead to a deterioration in the microbiological quality of sausages during storage. However, no more than 1/4 of the jowl content should be substituted with pullulan due to pullulan-negative effect on the general appearance, taste and texture of scalded sausages with assumed recipe composition.
The effects of mechanically deboned poultry meat (MDPM) and levels of collagen fibers on comminuted, cooked sausage quality characteristics were investigated using the central composite rotatable ...design of response surface methodology (RSM). Use of collagen fiber as an additive affected the sausage characteristics, but the effect depended on the amount of the MDPM used. While MDPM additions resulted in higher cooking loss and darker and redder frankfurters, the addition of collagen fibers improved cooking yields and contributed to the lightness of the final product. Higher collagen fiber content was also accompanied by a significant increase in frankfurter hardness regardless of the MDPM content. Use of collagen fibers countered the negative effects of MDPM on sausage quality attributes, especially on cooking yields and final product color.
► MDPM content increases moisture and decreases protein and fat levels of sausages. ► MDPM results in higher cooking loss, darker, redder and softer frankfurters. ► Cohesiveness and adhesiveness were affected only by varying MDPM levels. ► Collagen fibers improved cooking yields, lightness and hardness. ► The effects of collagen fibers on sausages color was dependent of the MDPM content.
