Post-harvest quality and sensory analysis of ‘Prata’ bananas produced in different cultivation field locations

Abstract

Banana ‘Prata’ has a significant demand in the Brazilian market, and Minas Gerais is one of the largest banana producers in the country. Scientific studies that evaluate the bananas quality produced in different cultivation regions are still incipient. Thus, this study evaluated the physical, biochemical and sensory attributes of banana ‘Prata’ from south and north of Minas Gerais and Vale do Ribeira (SP). Bananas from south were also cultivated in different production systems, organic and conventional. Data were submitted to multivariate analysis that provided the discrimination of the samples according to the cultivation regions. Bananas from southern presented higher levels of soluble solids and acidity, better taste, higher diameter and overall acceptance, where in the organic bananas were the most preferred by consumers. Fruit from northern stood out in appearance, texture, aroma and color, in addition to greater length. Fruit from Vale do Ribeira had higher levels of total phenolics and antioxidant activity. With these results we can assume that fruit quality is highly related to the specific climatic conditions from each producing region. Bananas from the south of Minas Gerais showed superiority for most of the evaluated traits, reflecting on consumer preference.
