“…The reduction of this ratio observed during storage days is indicative of quality losses. This change is affected by the physical and metabolic degradation of the spikelets and constitutes an important parameter to define the best alternative for storage (Menezes et al, 2017).…”

The baby corn has been gaining ground in the market and arousing interest of producers. However, there is a barrier in its production chain due to the lack of scientific knowledge in the harvest and post-harvest strategies. Therefore, the objective of this study was to evaluate the changes in the physicochemical characteristics of the baby corn stored at different temperatures and under controlled atmosphere. The studies were performed at UNIMONTES with the 'AG 1051' baby corn spikletes. Two tests were performed, one considering the spikelets in the straw and the other with the husked spikelets. The tests were carried out under CRD, in a 2 × 2 × 6 factorial scheme, that is two storage temperatures (16 and 25 °C), two controlled atmosphere conditions (with and without PVC plastic wrap) and six evaluation periods (0, 3, 6, 9, 12 and 15 days after harvest) with four replications. The quality characteristics of the spikelets were analyzed in the post-harvest. the post-harvest quality preservation of baby corn in the straw and the husked ones was affected by temperature, controlled atmosphere and evaluation period. The best storage condition to maintain the main quality characteristics of the spikelets at post-harvest was observed at the temperature of 16 ºC with controlled atmosphere use. For the spikelets preserved with the presence of straw, the maximum storage time for maintenance of post-harvest characteristics was four days, and for spikelets stored without straw, the maximum storage time was two days and 12 hours, both at refrigerated temperature (16 °C) and under controlled atmosphere.However, this vegetable presents a short post-harvest life, due to its active metabolism, and the shelf life of the product varies inversely with the respiration rate, causing reduction in water content, weight loss, changes in aroma, flavor and darkening of spikelets, making them undesirable regarding quality and appearance of the product (Bakry, El-Shorbagy, El-Desuki, El-Behairy, & Ibrahim, 2015; Saltveit, 2016).Aiming to develop the best strategy of storage of these horticultural crops, studies are necessary to guarantee the best yield and less waste of them. Some treatments, associated to refrigeration and controlled atmosphere storage, have shown good results in delaying senescence and prolonging life during storage (Vani, Rajasekhar, & Reddy, 2013).

“…Coatings with cassava starch and corn, for example, are inexpensive and edible and are capable of forming a thin layer of biodegradable plastic on the plant tissue, making it an efficient barrier against water loss, visual aspect of the fruits for commercialization (Luvielmo and Lamas, 2012) as already observed during the storage of fruits, such as: banana (Silva et al, 2015), tomato (Menezes et al, 2017), dragon fruits (Sanches et al, 2017a), among others.…”

The banana is a climacteric fruit with a limited shelf life in the environment and sensitive to storage under refrigeration, necessitating strategies to improve its post harvest conservation. In this sense, the objective of this study was to evaluate the effect of post harvest technologies on the quality and the prolongation of the useful life of 'Maçã' bananas during storage in ambient temperature condition (25 ºC). The fruits were obtained in physiological maturity in the green color and immersed in the following solutions: distilled water (control), cassava starch, maize starch and 3% calcium chloride for three minutes in addition to the sachets containing 3g KMnO4 for one period of 12 days in ambient condition. The evaluations took place every three days in terms of loss of fresh weight, firmness of peel, starch content, soluble solids, titratable acidity, pH, SS/AT ratio and incidence of rot. The postharvest treatments extended the shelf life of the fruits for 12 days in relation to the nine days of the control treatment. Among the evaluated technologies, the use of sachets of KMnO4 delayed ripening by observing fruits with higher green retention of the peel and pulp firmness, as well as lower fresh mass loss, starch degradation, soluble solids synthesis, ratio SS/AT and incidence of rot during the storage period. Thus, the ethylene absorber based on KMnO4 represents a viable alternative for the preservation of the quality of 'Maçã' bananas during commercialization at room temperature.
