Functionality and consumer acceptability of low-fat breakfast sausages processed with non-meat ingredients of pulse derivatives.

BACKGROUND

Owing to recent changes in consumer eating behaviours as well as potential cost savings for processors, pulse ingredients are finding more application in the meat processing industry. In this study, pea ingredients (pea fibre, FB; pea starch, ST; pea flour, PF) and chickpea flour (CF) were used, at 4% addition level, as fat replacers in low-fat breakfast sausages. The impact of these substitutions on processing and sensory characteristics of breakfast sausage was evaluated.

RESULTS

While reduction in fat content in breakfast sausage resulted in some detrimental changes in cooking as well as textural characteristics of the product, addition of binders significantly improved these attributes in low-fat breakfast sausages. Overall, treatment formulation did not significantly affect the pH and the instrumental colour attributes of cooked breakfast sausage. Addition of all binders resulted in reduced cooking loss and increased moisture retention in low-fat breakfast sausage (P < 0.05), whereas, FB and ST were significantly more effective in improving water holding capacity of low-fat breakfast sausage. Furthermore, while both FB and ST increased the hardness, cohesiveness and chewiness parameters of low-fat breakfast sausage (P < 0.05), PF and CF had no impact. Generally, the consumer overall liking and flavour acceptability of FB and ST in low-fat breakfast sausage were significantly higher than those of PF and CF.

CONCLUSION

The use of ST or FB as a fat replacer in breakfast sausages offers processors improved cook yield without negatively impacting the important sensory attributes of breakfast sausages. © 2021 Society of Chemical Industry.
