MANUTENÇÃO DA COLORAÇÃO DA LICHIA FRIGORIFICADA COM A UTILIZAÇÃO DE ÁCIDOS ORGÂNICOS Angela Vacaro de Souza Rogério Lopes Vieites Douglas Seijum Kohatsu Giuseppina Pace Pereira Lima Agrociencias cor Litchi chinensis escurecimento enzimático O objetivo do trabalho foi avaliar a influência dos ácidos orgânicos em diferentes concentrações na coloração de frutos de lichia. Os frutos foram tratados por: imersão dos frutos por 15 minutos em ácido ascórbico a 1% (T2); ácido ascórbico a 2% (T3); ácido ascórbico a 3% (T4); ácido cítrico a 1% (T5); ácido cítrico a 2% (T6) ácido cítrico a 3% (T7) e o controle (T1), embalados em bandejas de poliestireno expandido e filme de policloreto de vinila 0,020mm e armazenados em B.O.D. a 5ºC e 90±5 % de UR. O delineamento experimental foi em esquema inteiramente casualizado, com 6 tempos de armazenamento para as análises de coloração e enzimática e até atingirem o limite de comercialização para a análise da vida útil, sendo os frutos analisados a cada 3 dias com 3 repetições e 10 frutos por unidade experimental. Os parâmetros avaliados foram: análise visual do escurecimento, coloração e atividade específica da polifenol oxidase e da peroxidase. A utilização de ácido ascórbico a 3% mostrou-se ser o mais eficaz na manutenção da coloração dos frutos e na diminuição da atividade enzimática. 2009 artículo científico 1665-0204 https://www.redalyc.org/articulo.oa?id=81315095002 pt http://www.redalyc.org/revista.oa?id=813 Revista Iberoamericana de Tecnología Postcosecha application/pdf Asociación Iberoamericana de Tecnología Postcosecha, S.C.
