4. Conclusion
The main concern of this study was to develop a multifunctional dietary fiber without any adverse impact of recognized
technological effect. As a major effect of WFC, WFC increased redness of cooked sausages, regardless of presence/absence of nitrite. This effect done without nitrite condition could clearly depend on the unique red color of WFC. Moreover, WFC showed
additional effect on the color formation of cooked sausages with nitrite, accelerating the reaction and/or decomposition of nitrite that resulted in increased nitrosoheme pigments. Also, this suggested conclusion might be related to the result of decreased residual nitrite content with nitrite and WFC treatment. In addition, WFC inhibited lipid oxidation of cooked sausages due to antioxidant activity of carthamin. Consequently, WFC had positive effects, including improved cooking yield, on color formation, residual nitrite, and lipid oxidation of cooked sausages, and it could be possible to partially replace nitrite with WFC. Therefore, coloring of dietary fiber with natural pigments is a useful technique to expand the purposeful use of dietary fiber.
