The flour was added to the batter and mixed to a homogenous mass. Cookies were shaped by hand into flattened balls and baked in a
baking oven for 18 min at 170ºC. The prepared cookies were cooled at room temperature (30±2°C)
and packed in sealed polypropylene plastic bags for further quality evaluation. The physical
properties including color and texture were determined. The color values of the samples were
measured by Colorimetric Spectrophotometer (Hunter Lab, ColorFlex). The texture profile (hardness
and crispness) was performed by using a TA-XT plus Texture Analyzer (Ltd in Godalming, Surrey
UK). The test speed was set at 0.5 mm/sec with 50% deformation using a 2mm diameter cylinder
stainless probe. Sensory properties of cookies were tested on the basis of color, flavour, taste, texture
and overall preferences with 5-point hedonic rating scales by 30 untrained panelists.
