PHYSICAL CHARACTERIZATION OF ‘PRATA’ BANANAS SOLD IN THE MUNICIPALITY OF CHAPADINHA – MA

Abstract

Fruit growing is one of the segments of the Brazilian economy that has stood out in recent years and continues to evolve, thus, evaluating the post-harvest quality of fruits reduces risks and provides greater economic returns to the producer. The study aimed to characterize the physical and visual post-harvest quality of ‘Prata’ bananas, as well as visually identifying the conditions and handling methods in the commerce of the city of Chapadinha, Maranhão. Post-harvest analyzes were performed on a bunch of 12 ‘Prata’ bananas purchased from six commercial establishments in the central market of the city. The bananas were evaluated for quality in terms of external and internal appearance, physical characteristics and fruit handling. The data obtained were subjected to descriptive statistical analysis, determining the means and deviations for the tested factors, using the SISVAR computational program. The characteristics of commercial establishments, producers’ handling and transportation influenced the internal and external appearance of the fruits, with the majority being classified as Extra due to defects. The variables of length, pulp diameter, skin thickness and total fresh mass presented medium to low values or showed significant differences from those found in the literature for ‘Prata’ bananas. Incidence of stains and mechanical damage compromising the external appearance of bananas sold in the establishments were found, indicating low investment in post-harvest display and storage technologies. Additionally, they were transported in crowded plastic boxes, increasing susceptibility of the fruits to mechanical damage. Overall, it is evident that the post-harvest quality of the fruits is inherent to the application of technologies.
