Abstract

The banana is a highly perishable fruit in which storage and transport for a long period is limited due to the lack of post-harvest technologies that aim to retard fruit ripening. In this regard, the objective of this study was to evaluate the postharvest conservation period of the &lsquo;Prata-An&atilde;&rsquo; clone Gorutuba banana using different concentrations of 1-methylcyclopropene (1-MCP), associated with the modified atmosphere and refrigerated storage. Banana bunches (Musa spp. AAB) &lsquo;Prata-An&atilde;&rsquo; Gorutuba clone were obtained from Bel&eacute;m farm, located in Jana&uacute;ba-MG. The pieces were decomposed in bouquets of 4 fruits and submitted to 1-MCP application at concentrations of 0.0; 0.2; 0.4; 0.6; 0.8 and 1.0 ppm for 24 hours and stored refrigerated at room temperature to 13&plusmn;1 &deg;C. Every 5 days physical and chemical evaluations were performed. There was a delay in the ripening of fruits subjected to refrigeration and treated with 0.6 ppm of 1-MCP and increase in shelf life, due to probable inhibition of ethylene, which showed firmer fruits. Respiratory activity decreased with increasing concentration of 1-MCP. In refrigerated storage, fruits treated with 1-MCP were kept longer than 30 days. For the fruits kept at room temperature shelf life was 21 days for fruit subjected to concentrations of 0.4 to 1.0 ppm. However, the use of 1-MCP associated with the modified atmosphere under refrigeration directly influenced the postharvest conservation of bananas, allowing a longer period of commercialization.

Highlights

The banana tree (Musa spp.) is one of the most cultivated tropical fruit trees in the world
The banana has a quick ripening after harvest with a relatively short shelf life, a high respiration rate, and a highly perishable fruit which limits storage and transportation to distant markets
The firmness of the fruit (Figure 1A) showed a significant interaction between the study of the 1-MCP concentration and storage period, it was observed that the fruit had become stronger with increasing concentration of 1-MCP to approximately concentration of 0.65 ppm, where a maximum firmness of 46.4 N is found near day 5 of storage

Summary

Introduction

The banana tree (Musa spp.) is one of the most cultivated tropical fruit trees in the world. Its cultivation extends to regions of humid climate like the semiarid regions It is a fruit of great economic and social importance. The banana has a quick ripening after harvest with a relatively short shelf life, a high respiration rate, and a highly perishable fruit which limits storage and transportation to distant markets. To this end, the study of technologies that aim to increase postharvest conservation has been evaluated, in order to allow longer storage and transportation of bananas, allowing the production flow and reducing postharvest losses, offering quality products to the final consumer. Among the inhibitors of ethylene action, 1-methylcyclopropene (1-MCP) stands out. The return of plant product sensitivity to ethylene may occur due to the formation of new receptor sites (Hall et al, 2000; Li et al, 2017)
