Radiação gama ou antimicrobianos naturais na conservação de melão minimamente processado

Abstract

The aim of this research was to evaluated the effects of the gamma radiation and the natural antimicrobials in the conservation of fresh-cut melon storaged under refrigeration. Four experiments were accomplished: 1 and 2 – the varieties used were ‘Cantaloupe’ and ‘Pele de Sapo’ from Baraúna/RN and Juazeiro/BA, respectively; 3 and 4 - the varieties used were ‘Cantaloupe’ and ‘Gália’ from Cartagena (Spain). After harvesting, fruits from experiment 1 and 2 were sent to the Laboratory of Fruits and Vegetables at the University of Sao Paulo State (UNESP – Botucatu/SP). Fruits from experiment 3 and 4 were sent to the Postharvest and Refrigeration Group at the Technical University of Cartagena/Spain. After the manual processing (cut in trapezoidal sections) the fresh-cut melons of the experiment 1 and 2 were conditioned in polystyrene trays involved by polyethylene film and irradiated with doses: 0,0kGy; 0,1kGy; 0,2kGy; 0,3kGy; 0,4kGy and 0,5kGy. After processing, fresh-cut melons from experiment 3 and 4 were immersed for 1 min at 5ºC in water (control); vanillin (1000 mg L-1 and 2000 mg L-1); cinnamic acid (148,16 mg L- 1 and 296,32 mg L-1). Two additional treatments consisted on the application of cinnamic acid vapor (148,16 mg L-1 e 296,32 mg L-1) on fresh-cut melons within the packages (polypropylene trays heat-sealed with polypropylene). The storage was realized during 10 days in a cold camera to 5±1ºC and 85-90% HR (experiment 1 and 2) and to 5±1ºC and 85- 95% HR (experiment 3 and 4). The quality alterations were detected through the analyses: loss of fresh mass, postharvest conservation, firmness, pH, acidity titratable, soluble solids, reducing and total reducing sugar content, ascorbic acid, vitamin C, respiration rate, ethylene production, gas composition (CO2 and O2), enzymes activity (peroxidase, polygalacturonase and pectinmethylesterase), antioxidant...

O presente trabalho teve por objetivo verificar os efeitos da radiação gama e de antimicrobianos naturais na conservação de melão minimamente processado, armazenado sob refrigeração. Foram realizados 4 experimentos: 1 e 2 - frutos de melão Cantaloupe e Pele de Sapo provenientes de Baraúna/RN e Juazeiro/BA, respectivamente; 3 e 4 - frutos de melão Cantaloupe e Gália provenientes da região de Cartagena (Espanha). Após a colheita, os frutos dos experimentos 1 e 2 foram transportados ao Laboratório de Frutas e Hortaliças da Faculdade de Ciências Agronômicas – UNESP – Botucatu/SP, e os dos experimentos 3 e 4 transportados para o Laboratório de Postrecolección e Refrigeración da Universidad Politécnica de Cartagena/Espanha. Após o processamento manual (corte em seções trapezoidais) os melões MP (minimamente processados) dos experimentos 1 e 2 foram acondicionados em embalagens de poliestireno expandido recobertas com filme de polietileno e irradiados nas doses: 0,0kGy; 0,1kGy; 0,2kGy; 0,3kGy; 0,4kGy e 0,5kGy. Os melões MP dos experimentos 3 e 4, após o processamento, foram imersos durante 1 minuto a 5ºC em: água (testemunha); vanilina (1000 mg L-1 e 2000 mg L-1); ácido cinâmico (148,16 mg L-1 e 296,32 mg L-1) e outros dois tratamentos consistiram em aplicação de vapor de ácido cinâmico (148,16 mg L-1 e 296,32 mg L-1) nos melões MP dentro da embalagem (bandejas de polipropileno termo seladas com filme de polipropileno). O armazenamento refrigerado foi realizado durante 10 dias 5±1ºC e 85-90% UR (experimentos 1 e 2) e à 5±1ºC e 85-95% UR (experimentos 3 e 4). As alterações na qualidade foram detectadas por meio das análises: perda de massa fresca, conservação pós-colheita, firmeza, pH, acidez titulável, sólidos solúveis, teores de açúcares redutores e redutores totais, ácido ascórbico, vitamina C, taxa respiratória, produção de etileno...
