Abstract(s)
Pretendeu-se avaliar o comportamento de uma variedade de figo lampo com o objetivo de
determinar o potencial de comercialização no mercado interno e principalmente no
mercado externo. Um dos principais problemas dos figos para comercialização em fresco é a
sua grande perecibilidade pós-colheita, quer refrigerados quer em prateleira, quer
conjugando as duas situações. Foi realizado um ensaio de campo num pomar de figo Lampo,
localizado em Cachoeiras, Vila Franca de Xira, no qual foram colhidos 300 figos para
avaliação, separados em 2 lotes: Lote A (mais maduros); Lote B (mais verdes). Os figos foram
colocados sob condições de refrigeração e de prateleira. Os indicadores de qualidade foram:
calibre, massa, Brix e firmeza. Os resultados obtidos para firmeza e Brix correspondentes
aos dias de frio e de prateleira a que os figos foram sujeitos permitiram também avaliar o
estado de maturação. Constatou-se que é possível a comercialização para o mercado
externo até 4 a 5 dias de armazenamento. Relativamente ao mercado interno é possível
colher a fruta madura, mas a comercialização e o consumo devem ser imediatos, pois nesse
caso, a vida útil diminui, no máximo três dias, não devendo ultrapassar os 2 dias de frio.
The main goal of this work is to evaluate the behaviour of a variety of lampo fig in order to determine the commercial potential in the domestic market and especially in the export market. A major problem for producers of fresh figs is its great perishable postharvest either refrigerated or shelf life, or combining the two. It was intended with this work, at the request of a producer’s organization, assess Fig behaviour Burro over several days of cold and days of shelf, in order to determine its commercial potential in the domestic market, especially in external market. It was carried out a field trial in a fig orchard , located in a village of Vila Franca de Xira county, where there were evaluated 300 figs, separated into 2 different lots, according to its ripeness (green and ripe). Figs were put under refrigeration conditions and the shelf. After analyzing the cold storage and the shelf life days which the figs were subject, assess their degree of ripeness, the texture parameters and Brix, it was concluded that for the foreign market the shelf life is on average four to five days if the cold storage is below four days. For the domestic market it is possible to harvest the ripe fruit, but the distribution and consumption should be immediate. In this case, the shelf life decreases to three days, and the cold storage must not exceed 2 days.
