Effects of fig and pineapple powder on metabolite compounds and health-promoting properties in fermented goat meat sausage.

OBJECTIVE

The objective of this research was to identify the metabolite compounds and health-promoting properties of goat meat fermented sausages containing different amounts of fig and pineapple powder (0.1%, 0.25%, and 0.5%), which are presented by F1, F2, F3 and P1, P2, P3, separately.

METHODS

Fermented sausages were manufactured from the lean meat of female goats. The samples extracted from the goat meat fermented sausages were evaluated for their metabolite compounds, antioxidants, and angiotensin-converting enzyme inhibitory activity.

RESULTS

The results showed that the diphenyl picrylhydrazyl radical scavenging activity, azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, and angiotensin-converting enzyme inhibitory activity were the highest in F3 (p<0.05), whereas the hydroxyl radical scavenging capacity was the highest in P3 (p<0.05). In addition, F3 and F2 showed the highest superoxide anion radical scavenging activity (p<0.05), whereas F3 and P3 showed the highest copper chelating activity (p<0.05). Based on the metabolite compounds, hydrophobic amino acids, aromatic amino acids, and bitter amino acids were abundant in F3. Both F3 and P3 contained high concentrations of umami-producing compounds.

CONCLUSION

The incorporation of 0.5% fig powder into goat meat fermented sausage showed improved biological activities based on metabolite compounds.
