Resumo: | Coatings with natural edible products that can add nutritional or functional value in fruits are an innovative alternative to help in the conservation of these foods. The coatings have the function of protecting the fruits by forming a barrier to the attack of pathogenic microorganisms, controlling gaseous exchanges and water vapor, thus helping to maintain post-harvest quality of fruits, without losing their physical, chemical and sensorial characteristics. The objective of this work was to evaluate the effect of the green propolis extract (GPE) coated as a film on papaya fruits (Carica papaya L.). The fruits received were divided into two treated and untreated groups. In the treated fruits it was applied with the aid of spray, 20% GPE and stored for 8 days under ambient conditions. The variables analyzed were weight loss, maturation time (shell color) and coating influence on the incidence and severity of spontaneous diseases. To characterize the green propolis were analyzed spectrophotometry with the reagents FolinCiocalteau and aluminum chloride for phenolics and total flavonoids, respectively. Phenolic and flavonoid acids were also identified and quantified by reverse phase high performance liquid chromatography (HPLC). The antioxidant potential was assessed by DPPH radical sequestration and expressed in EC-50. The mean phenolic, total flavonoid and antioxidant potential contents were respectively 450.0 mg of gallic acid (GA) equivalents / 100 g; 8.84 mg of quercitin (EQ) equivalents / 100 g and 0.331 mg / mL. The fruits coated with EEP remained longer with the coloration of the bark with green tones than the fruits without propolis, since the change of the coloration of the bark to yellow-orange tones occurred on the 5th and 3rd day of evaluation, respectively. The use of the coating significantly influenced the reduction of mass loss, with the treated fruits losing 8.81% less than the untreated fruits. And in relation to the damages caused by post-harvest diseases, a significant difference was observed between the coated and control fruits. On the 8th day of evaluation, all fruits were contaminated, but it was observed that the fruits treated were on average 35% disease severity, while the untreated fruits had 50.5% disease severity. The high levels of flavonoids, phenolics and the antioxidant potential of green propolis influenced the increase in the shelf life of coated fruits, as well as delayed the symptoms of severity of post harvest diseases. |

Os revestimentos têm função de proteger os frutos formando barreira ao ataque de microrganismos patogênicos, controlar trocas gasosas e vapor de água, podendo assim auxiliar na manutenção da qualidade pós-colheita de frutos, sem que estes percam suas características físicas, químicas e sensoriais. Objetivou-se neste trabalho avaliar o efeito do extrato de própolis verde (EEP) revestido como filme em frutos de mamão formosa (Carica papaya L.). Os frutos recebidos foram divididos em dois grupos os tratados e não tratados. Nos frutos tratados aplicou-se com auxílio de spray, EEP 20% e armazenou-se por 8 dias sob condições do ambiente. As variáveis analisadas foram perda de massa (pesagem), tempo de maturação (coloração da casca) e influência do revestimento sobre a incidência e severidade de doenças espontâneas. Para caracterizar a própolis verde foram realizadas análises dos compostos por espectrofotometria com os reagentes Folin-Ciocalteau e cloreto de alumínio para fenólicos e flavonoides totais, respectivamente. Os ácidos fenólicos e flavonoides também foram identificados e quantificados por cromatografia líquida de alta eficiência (CLAE) em fase reversa. O potencial antioxidante foi avaliado pelo sequestro de radical DPPH e expresso em EC-50. Os teores médios de fenólicos, flavonoides totais e potencial antioxidante foram respectivamente de 450,0 mg de equivalentes de ácido gálico (EAG)/100g; 8,84 mg de equivalentes de quercitina (EQ)/100g e 0,331 mg/mL. Os frutos revestidos com EEP permaneceram por mais tempo com a coloração da casca com tons verdes do que os frutos sem própolis, pois a mudança da coloração da casca para tons amarelo-alaranjado ocorreu no 5° e 3° dia de avaliação, respectivamente. O uso do revestimento influenciou significativamente na redução da perda de massa, sendo que os frutos tratados perderam 8,81% a menos que os frutos não tratados. E em relação aos danos causados pelas doenças de pós colheita observou-se diferença significativa entre os frutos revestidos e controle. No 8° dia de avaliação, todos os frutos estavam contaminados, mas observou-se que os frutos tratados estavam em média com 35% de severidade de doença, enquanto que, os frutos não tratados apresentavam 50,5% de severidade de doença. Os elevados teores de flavonóides, fenólicos e o potencial antioxidante da própolis verde influenciaram no aumento na vida de prateleira dos frutos revestidos, assim como retardaram os sintomas de severidade de doenças pós colheita.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Agrárias e Ambientais (ICAA) – SinopUFMT CUS - SinopAgronomia - CUSWobeto, Carmenhttp://lattes.cnpq.br/7629112688399234Wobeto, Carmenhttp://lattes.cnpq.br/7629112688399234Bonaldo, Solange Mariahttp://lattes.cnpq.br/3703629752105309Andrade, Ednaldo Antônio dehttp://lattes.cnpq.br/5150981445039994Oliveira, Julian do Carmo Fonseca de2019-04-17T13:51:53Z2018-09-242019-04-17T13:51:53Z2018-09-20info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetOLIVEIRA, Julian do Carmo Fonseca de.
