Preparation and evaluation of brownies soft biscuit from non-wheat flour using date molasses

Abstract

The effect of fortification of brownies soft biscuit, which prepared from corn and rice flours as a non - wheat flour with different levels of date molasses (DM) as a natural source of iron and other nutrients on the quality was studied. The results showed that RF+60%DM describing the extreme sensory evaluation points followed by RF+70%DM then CF+60% then CF+70% DM. Physical properties tests of biscuits showed that the volume of biscuits significantly increased (p<0.05) by increasing the ratio of DM up to 60% and 70%. Texture results showed that firmness at zero time were lower for CF+50%DM (14.69), CF+ 60% DM (8.53), RF+ 50% DM (13.22) and RF+ 60% DM (7.74). There is a direct relationship between the increase in the ratio of date molasses and the increase in the values of K, Ca, Mg, Fe, Zn and Mn in produced soft biscuits. Iron contents results of RF+ 70% DM, RF+ 60% DM and CF+ 70% DM were 3.85, 3.67 and 3.35 mg/100 gm biscuit products respectively. They give the highest values of iron contents. Consumed of 100 gm of biscuits made by enrichment with 50 or 60 % of DM in the biscuit's dough give about 26.5 to 34.4 % for adolescent males and 19.5 to 24.5% for adolescent females.
