Physiochemical characteristics, sensorial analysis and fruit conservation of a black Sigatokaresistant banana genotype

The cultivar Prata Anã is widely grown in the North of Minas Gerais State, Brazil, hence, the banana business in the region is based on a variety susceptible to Black Sigatoka. Although there are resistant cultivars being recommended to cultivation in the region, studies related to post-harvest conservation are still scarce. The objective of the present work was to evaluate the storage period and physiochemical and sensorial characteristics of cultivars, Fhia - 02 and Preciosa, both resistant to Black Sigatoka, and the effect of the modified atmosphere associated with cooling. Three experiments were carried out, the first under ambient temperature, the second at 12ºC and the third at 15ºC, The experiments were arranged in randomized block design with split-plots in the time, having in the plots a 2x2 factorial (with and without packing) x (Fhia - 02 and Preciosa), and in the subplots the evaluations at six and two days, at 12, 15 and 25º C, with four repetitions and three fruits per experimental unit. After the treatment, the fruits were placed in expanded polystyrene trays (without packaging) and 10µm and 16µm packagings and relative humidity of 90 %. The evaluated characteristics were size, diameter, color, firmness, loss of fresh matter, total soluble solids (TSS), total titratable acidity (TTA), TSS/TTA, pH and sensorial analysis. The use of packaging associated with cooling allowed fruit storage for 28 days keeping its physical-chemical characteristics.
