Passion fruit, a well-known and commercialized fruit, is currently the target of studies that show its nutritional properties, namely its bark, rich in vitamins, minerals and dietary fiber, specifically soluble fibers, which bring benefits such as glycemic control and prevention of cardiovascular diseases. Due to the high rate of disposal of passion fruit peels, the use of the same in bakery products is an alternative to avoid its waste, taking advantage of the fruit in its entirety. The aim of this study was to prepare the biscuits with the flour from the shell of the passion fruit. This is an experimental, cross-sectional and quantitative study that was developed in the laboratories of Dietary Technique and Sensory Analysis of Food of the University Center of Science and Technology of Maranhão - UNIFACEMA, located in the city of Caxias - MA. The sensory analysis of the product was performed with 62 untrained evaluators, using the 9-point hedonic scale and 5-point purchase intention, by signing the TCLE. Microbiological analysis was performed to determine the microbiological conditions of the product. The results obtained show that of the three samples (A, B and C) developed, two (A and B) obtained acceptance by the evaluators. The results of the microbiological analysis indicated that the three samples are in accordance with current legislation. Therefore, the preparation of the biscuit proved to be a technological potential in the bakery market and as a healthy, sustainable and economic food option.
