Bread is a product widely consumed since ancient times, so many scholars seek to create new formulations that give them more flavor and nutritional quality through the full reuse of food. Soursop is rich in minerals such as calcium, potassium, magnesium and vitamins (A, B and C). Thus, the objective was to elaborate loaves of bread added with different concentrations of soursop residue flour, as well as to evaluate the sensory characteristics of the elaborated products. Initially the soursop peels were dried in a 60 ° C circulating oven for 24 hours and then flour was obtained. Then different formulations of loaves of bread were prepared: PFC (0% soursop residue flour), PF10% (10% soursop residue flour) and PF20% (20% soursop residue flour). Sensory analysis was performed using the affective test with a nine-point structured hedonic scale and the purchase intention test. From the results, it was inferred that in the sensory analysis, the PFC sample had an acceptability higher than 80% for all evaluated attributes, while the PF10% bread had an acceptability index higher than 73% and the PF20% bread reached acceptability index. over 66% for all appreciated attributes. Therefore, it was found that it is possible to partially replace wheat flour with soursop residue flour in the production of loaf breads, since PF10% was not affected by the addition of flour.

Mango (Mangifer indica L.) is a tropical fruit much appreciated for its sensory characteristics, however, it is an extremely perishable food, and part of its production is destined to the product processing industry. In this processing tons of waste are produced, which are rich in many nutrients, but most of them are discarded, becoming an environmental contaminant. One way around this problem is to make full use of these components that can be added to traditionally consumed products such as yogurt. Thus, the objective was to elaborate different formulations of yogurt added to mango residue flour, as well as to evaluate the sensory characteristics of the elaborated products. Initially, the mango residues were dried in an air circulation oven at 60 ° C / 24 hours and then the flour was prepared. Subsequently, different yogurt formulations were made: IC (0% of mango residue flour), IM5% (0.5% of mango residue flour) and IM10% (1.0% of mango residue flour) . Sensory analysis was performed through acceptance test using the 9-point hedonic scale and purchase intention test. Based on the results, it can be observed that the CI had an acceptability higher than 80% for all the evaluated attributes, while the IM5% sample showed an acceptability index higher than 74% and the IM10% had an acceptability index above 62% for all attributes. the attributes appreciated. In this context, it was found that, sensorially, the IM5% presented good acceptance, proving to be a viable alternative to add nutritional value to yogurt.

O objetivo deste trabalho foi avaliar as propriedades antioxidantes dos extratos da flor e da folha de malvavisco. Os antioxidantes sintéticos podem causar malefícios à saúde humana, por isso, há uma crescente busca por fontes de antioxidantes naturais. Os extratos foram obtidos por agitação por 15 minutos, a 40 ºC, utilizando-se álcool de cereais 60% e, a partir do extrato, foram determinados os teores de fenólicos totais, flavonoides totais e a atividade antioxidante, pelos métodos de FRAP, ABTS e IC50. Os resultados indicam que os extratos da flor e da folha de malvavisco são ricos em compostos fenólicos totais e flavonoides totais, além de se manifestarem como potentes antioxidantes. Conclui-se, assim, que os extratos de malvavisco são uma alternativa promissora de substituição dos antioxidantes sintéticos.
