Effect of incorporation of carrot pomace powder and germinated chickpea flour on the quality characteristics of biscuits
Abstract
The study on utilization of carrot pomace powder (CPP) and germinated chickpea flour (GCF)
in biscuits was undertaken to upgrade the nutritional quality and assess the acceptability. The
biscuits were prepared from composite flours by incorporating 5, 8 and 10 parts of germinated
chickpea flour and similar corresponding parts of carrot pomace powder in to wheat flour.
The biscuits were analyzed for their physical properties, chemical composition and sensory
properties. The spread ratio of the biscuits increased from 6.1 to 8.4 with the increase of CPP
and GCF in the blends. With the increase in the concentration of CPP and GCF, there was
an increase in protein, ash and crude fiber contents. The crude fiber content of the biscuits
supplemented with 10% CPP and GCF was the highest (3.2%). The biscuits supplemented with
CPP and GCF up to 8% level were of acceptable sensory quality.
Product development
Biscuits were prepared from different blends of refined wheat flour, germinated chickpea flour and carrot pomace powder in the respective ratios of 100:0:0, 90:5:5, 84:8:8 and 80:10:10. Refined wheat flour biscuits were considered as control. The standardized formulation for the biscuits had the ingredients as 100 g flour, 50 g sugar, 45 g butter fat, 1.5 g ammonium bicarbonate and required amount of milk. Butter fat and ground sugars were creamed for about 3 min achieve a uniform consistency. The flour, required amount of milk and ammonium bicarbonate were added to the creamed mixture and mixed for 8 min at medium speed in dough mixer to obtain a homogenous mixture. The dough was rolled out into thin sheet of uniform thickness and cut into desired shape using mould. The cut pieces were placed over a perforated tray and transferred into a baking oven at 190°C for 10 - 15 min. The well baked biscuits were cooled to room temperature and stored in air tight container till further use.
