Abstract

Flour was fortified with premix containing ferrous fumarate and folic acid. Organic acids such as citric acid, malic acid and tartaric acid, which are promoters of iron bioavailability, were added at three levels and their influence on rheological and breadmaking characteristics was studied. Farinograph water absorption increased with fortificants, but with addition of organic acids there was a decrease. Maximum pressure was 77mm in control, which increased to 78–88mm with the addition of different acids to the fortified flour. Addition of organic acids to fortified flour brought about a decrease in peak viscosity, hot paste viscosity, cold paste viscosity and setback values. The L, a and b values of fortified breads were similar to that of control. Sensory analysis revealed marginal differences in the overall quality of breads prepared with fortified flour with the addition of organic acids.
