Abstract
One of the great challenges of developing low-fat products is to maintain their sensory characteristics. Polydextrose can be used as a fat substitute without causing major changes in the final product. The objective of this study was to evaluate the physicochemical characteristics, nutritional properties and acceptance of cheese breads made with polydextrose. Four formulations were elaborated: formulation 1 (without substitution of oil for polydextrose); formulations 2, 3 and 4 (containing different concentrations of oil substitution and polydextrose). A total of 100 untrained testers aged 18-62 participated in the sensory evaluation. In the physicochemical analyzes the water moisture, ash, protein, fat, texture, specific volume and color contents were determined. Theoretical calculations were performed for the quantification of carbohydrates (by difference) and fibers. The results showed that for the attributes evaluated, acceptance of the formulations was higher than 70%, except for intention to purchase of the standard formulation. It was observed that the development of formulations included 4% polydextrose, with texture similar to the standard pattern. Thus, an addition of polydextrose in cheese breads, allows the prodution of products with lower lipid content, higher fiber content, good sensory acceptance and specific technological characteristics for the standard, which shows its commercialization potential.
