A farinha da entrecasca de melancia (FEM) foi obtida, sua composição determinada e utilizada em formulação de bolos. Elaboraram-se bolos sem a FEM (controle) e contendo 7 e 30% de FEM em substituição à farinha de trigo (experimentais). A composição química, características físicas, físico-químicas foram determinadas. Na avaliação sensorial, cem provadores não treinados receberam amostras em blocos balanceados e realizaram testes sensoriais, utilizando escala hedônica de 9 pontos e comparação múltipla. Os dados obtidos foram avaliados por estatísticas descritivas, ANOVA, testes de Tukey e Dunnet. Os resultados revelaram que 100 g da FEM continham 9,06 g de umidade, 12,72 g de cinzas, 0,7 g de lipídios, 1,20 g de proteínas, 31,01 g de fibras insolúveis, 45,21 g de glicídios totais e 192,75 kcal. Nos bolos experimentais, os pesos, alturas, diâmetros e rendimentos foram maiores e o índice de expansão menor, bem como, o volume aparente do bolo com 30% FEM foi menor. Os bolos experimentais apresentaram menor pH, maior acidez titulável, maiores teores de fibra e umidade, menores de glicídios totais e reduzido valor energético. Os bolos obtiveram boa aceitação e mais de 60% dos provadores comprariam os bolos. O bolo com 7% FEM foi ligeiramente melhor que o controle, diferindo no aroma e sabor do que continha 30% FEM. Portanto, o uso de FEM para produção de bolos, nas condições dessa pesquisa, é viável do ponto de vista tecnológico, nutricional e sensorial. The flour of watermelon inner skin was obtained, its composition was determined, and it was used in the cake formulation. Cakes without watermelon inner skin (control) and others containing 7 and 30% of watermelon inner skin(experimental), a non-wheat flour substitute, were elaborated. The chemical composition, physical, and physicochemical characteristics were evaluated. In the sensory evaluation, one hundred non-trained panelists were assigned blocks of four samples and performed sensorial tests using a nine point hedonic scale and multiple comparison. The obtained data were evaluated by descriptive statistics, ANOVA, and Tukey and Dunnet tests. The results revealed that 100 g of the watermelon inner skin flour contained 9,06 g of moisture, 12,72 g ashes, 0,7 g fats, 1,2 g proteins, 31,01 g insoluble fibers, 45,21 g total carbohydrates, and 192,75 kcal. The weight, height, and yield were higher and the diameter was greater in the experimental cakes, whereas the spreading factor and the apparent volume of the cake with 30% of watermelon inner skin flour were lower. The experimental cakes presented lower pH, higher titratable acidity, higher contents of fiber and moisture, lower contents of total carbohydrates, and reduced energetic value. The cakes presented good acceptance and more than 60% of the panelists would buy the cakes. The cake with 7% of watermelon inner skin flour was slightly better than the control and differed from the cake containing 30% of watermelon inner skin flour in aroma and flavor. Therefore, the use of watermelon inner skin flour for cake production, under the conditions of this research, is viable from the technological, nutritional, and sensorial point of view
