Abstract

Curcumin added as a solution in Propylene Glycol (PG) at 24 ppm on flour basis imparted an acceptable light yellow colour to fruit bread containing ginger candy. The visual yellowness was comparable to that of tartrazine added at 47 ppm on flour basis. After undergoing the processing stages of dough mixing, fermentation and baking, retention of curcumin (84%) was comparable to that of tartrazine (85%). On analysis, the concentration of curcumin and tartrazine were 12 ppm and 22 ppm respectively. Addition of curcumin as a fine powder at the level of 25 ppm on flour basis during the dough mixing step, resulted in a bread with reduced yellowness (curcumin retention (73.6%), but the use of PG is avoided. There was no appreciable loss of colour after storage for three days at ambient conditions (curcumin retention 71%). Curcumin is a promising safe natural yellow colourant for fruit bread.
