Physical property measurements including percentage increase/decrease of crest height, moisture and specific gravity, color by Hunter colorimeter and Texture Profile Analysis (TPA) by TAXT. Plus Texture analyzer was done for the final product. The Sensory attributes, appearance, flavor, sweetness, texture and general acceptability, were evaluated by a group of un-trained panelists, using a 9-point Hedonic scale. Sensory and instrumental data were analyzed statistically.
