Influência da concentração e da proporção fruto: xarope na desidratação osmótica de bananas processadas

Abstract

Considering the technological limitations of the traditional processes for production of banana fig with standard quality, the osmotic dehydration appears as an option to the standardization of this process. In this work to determine parameters of the banana osmotic dehydration process and to evaluate the influence of osmotic solution concentration on the physical chemical caracteristics of the fruit and stablish drying curves of pre treatment bananas through osmotic dehydration with and without vacuum. It was concluded that is possible to obtain dehydrated banana as a product of intermediate moisture, through osmotic pre treatment followed by drying. The characteristics of the product were influenced by concentration and proportion fruit:xyrop of the used medium.
