Oleogels Based on Starch and Natural Extracts from Cassava (Manihot esculenta) as a Fat Replacement in Cookies

Oleogels, a semi-solid fat-like material, have emerged as a promising alternative to traditional saturated fats in food products. This study aimed to develop and characterize novel oleogels using starch and extracts from cassava (Manihot esculenta) to be used as a fat replacement in cookies, addressing the growing demand for healthier baked goods. Cassava starch was used as the structuring agent, while extracts provided functional properties to the oleogels. The oleogels were prepared and then incorporated into a cookie formulation, fully replacing the conventional fat. The resulting cookies were analyzed for their physicochemical properties, including texture, moisture content, and color. Rheological and microscopy analyses were also subjected to a sensory evaluation panel. The results demonstrated that the cassava-based oleogels effectively mimicked the functional role of fat, producing cookies with a significantly lower fat content. The cookies made with the oleogels exhibited comparable textural attributes and sensory acceptance to the full-fat control group, with no significant differences in flavor or mouthfeel reported by the panelists. These findings suggest that oleogels derived from cassava are a highly effective and innovative solution for producing healthier cookies without compromising quality, representing a viable strategy for fat reduction in the food industry.
