Utilization of composite flour (red bean, catfish, oyster mushroom and tempeh formula flour) in making cookies

Abstract

Local food ingredients can be used as alternative ingredients for cookie products to help ending hunger and overcome malnutrition are the objectives of SDG 2 and 3. This study aims to obtain the optimum cookie formula using composite flour from local food ingredients consisting of red bean flour, catfish flour, oyster mushrooms flour, and tempeh formula flour using the design expert program v.13 Response Surface Methodology (RSM) Box Behnken Design/BBD. Independent variables are different levels of red bean flour (20-45 g), catfish flour (10-45 g), oyster mushroom flour (5-25 g), and tempeh formula flour (5-35 g) with 29 (twenty-nine) different runs of 4 (four) similar center points. Using goal settings for each response based on proximate composition achieved from the best definition of each response to achieve high-quality cookies, an optimum formulation of cookies was obtained at 44.21% red bean flour, 34.39% catfish flour, 7.46% oyster mushroom flour, and 20.52% tempeh formula flour, with a desirability level of 1.00.
