Caracterização físico-química, atividade antioxidante e enzimática da mangaba (Hancornia speciosa) e sua aplicação para a produção de doce de leite em pote com leite de búfala. 2023. Trabalho de Conclusão de Curso (Tecnologia em Alimentos) – Universidade do Estado do Pará, Belém, 2023.https://bibliotecadigitaldetcc.uepa.br/handle/riuepa/535The research aimed to determine the physicochemical properties, profile of bioactive compounds, enzymatic activity and antioxidant capacity of mangaba (Hancornia speciosa), and its application in the elaboration of buffalo dulce de leche. The physical and chemical parameters for buffalo milk and mangaba pulp were quantified based on Brixº, pH, acidity, moisture, ash, fat and protein analyses, and were within the limits established by law. The mangaba pulp presented 3.22% of crude fiber, 4.68% of reducing sugars. Regarding the bioactive composition, mangaba pulp showed an average content of phenolic compounds of 229,91 mgEAG/100g, for antioxidant capacity by the ABTS method 10.64 µ𝑚𝑜𝑙𝑇𝐸/g, ascorbic acid content of 104, 9mg/100g. The mangaba pulp showed excellent enzymatic activity with 4,02 Units/g for the peroxidase enzyme and 1,0 Units/g for the polyphenoloxidase enzyme. In the preparation of dulce de leche with mangaba pulp, preliminary tests were carried out at concentrations of 15, 20 and 30% of pulp. The parameters analyzed were Brixº, pH, total acidity, humidity, ash, proteins, fats, reducing sugars, carbohydrates and caloric value. The candy showed bioactive composition regarding the analysis of phenolic compounds with an average of 47,61 mgEAG/100g and antioxidant capacity by the ABTS method with an average of 2.83 µ𝑚𝑜𝑙𝑇𝐸/g. The microbiological parameters evaluated showed absence of Salmonella sp, fecal coliforms ˂ 3.0 MPN/g, all in accordance with the legislation. The mangaba pulp showed positive results regarding its bioactive composition and the addition of mangaba pulp in the preparation added value to the buffalo dulce de leche.Língua PortuguesaAbertoMangabaBuffalo milkAntioxidantEnzymatic activityDulce de lecheTrabalho de Conclusão de Curso (TCC)
