Efeito de diferentes tratamentos químicos sobre o escurecimento enzimático da banana (Musa sapientum) minimamente processada. 44 f. Trabalho de Conclusão de Curso (Tecnologia de Alimentos) - Universidade do Estado do Pará, Belém, 2019.https://bibliotecadigitaldetcc.uepa.br/handle/riuepa/559Maintaining color in minimally processed vegetables is critical because most of them are susceptible to enzymatic browning caused by the enzymes Polyphenoloxidase (PPO) and Peroxidase (POD), which should be controlled without sensory or nutritional damage to the products. The aim of this study was to evaluate different chemical treatments (Cassava 3% (TF), Cassava 3% + Citric Acid 1% (TF + A) and Citric Acid 1% (TA) and a control test for inhibition. of enzymatic browning. Bananas were stored in hermetically sealed packages and stored at 5 ± 1 ° C. The samples were analyzed by observing their alterations on alternate days and the time (days) represented by 0, 2 and 4. The photographic record analysis, mass loss, microbiological parameters (Mesophilic and psychotrophic bacteria, total coliforms) were determined. at 35 ° C, thermotolerant coliforms at 45 ° C and Salmonella spp), physicochemical (titratable acidity, pH and soluble solids) and enzymatic analysis of polyphenoloxidase (PPO). The results showed that the treatments with the best performances were with 1% citric acid followed by cassava starch 3% + 1% citric acid treatment in all parameters analyzed in this work.Língua PortuguesaAbertoSilver bananaPolyphenoloxidaseEnzymatic browningTrabalho de Conclusão de Curso (TCC)
