    Abstract:
    A functional ingredient mix (FIM) comprising debittered and defatted fenugreek seed powder (70%) and flaxseed powder (30%) was used in cookies. Ash, fat and protein, dough development time, resistance to extension and peak viscosity values increased as the level of FIM increased from 10 to 30% in the blend. Beyond 20% of FIM substitution, the quality characteristics of cookies were adversely affected. Use of soya lecithin produced a significant improvement in the overall quality of the cookies with 20% FIM. Linolenic acid and total dietary fiber content of the cookies with 20% FIM and lecithin contained four times the amount of linolenic acid (2.3%) and double the amount of dietary fiber (13.04%) when compared with the control cookies (0.5% and 6.22%) respectively. Surface scanning electron microscopy of cookies with different levels of FIM from 10 to 30% showed that there was a disruption in the matrix.
