Abstract

Effects of processing parameters such as creaming time, dough mixing time, cookie thickness, baking temperature, time and principal ingredients viz. sugar, fat and water on quality of sugar snap cookies were investigated using the Response Surface Methodology. Shorter mixing time (100s) along with higher creaming time (400s) was desirable for producing softer cookies with tender bite and higher spread factor. Cookie baked at 190°C had superior quality in terms of hardness and spread factor as compared with those baked either at lower or at higher temperature. At lower baking temperature, hardness of cookie increased as the baking time was decreased below 14min. Hardness also increased significantly with increase in water content at all levels of sugar concentration in the formula. Optimum cookie quality was obtained with creaming time of 400s and mixing time 100s to make cookie dough containing 59.65% sugar, 46.68% fat and 14% water. Cookie thickness 11mm, baking temperature 190°C and baking time of 16min 30s resulted in best cookies.
