Abstract: Bananas are one of the most consumed fruits in the world, and are produced in most tropical countries. They represent the fourth most important source of energy after corn, rice and wheat. Their high starch concentration when processed into flour is of interest as a food source and for industrial purposes. In countries such as Brazil and Venezuela, where imported wheat is widely consumed, this can be mixed with other cereals and vegetables with a high starch content as sources of nutrients at lower costs. The present study aimed to process and characterize the physical and chemical properties of green banana flour from the terra variety (Musa paradisiaca). To obtain the flour, the fruits were cut and immersed in a solution of (0.8% citric acid for 30 minutes and 0.5% ascorbic acid for 30 minutes). The efficiency of these treatments was then evaluated through sensory analysis. After dehydration and grinding, the following determinations were made: pH; soluble solids; water activity; total soluble solids; alcohol-soluble acidity; reducing and non-reducing carbohydrates; starch; fibers; moisture; lipids; proteins and ash – determinations according to the method (IAL, 2007). The average values obtained for the flours at 75º and 85ºC, respectively, were: for physical-chemical characterization – pH 5.70%; soluble solids 0.5%; water activity 0.536%; alcohol-soluble acidity 3.85%; reducing and non-reducing carbohydrates 0.13%; starch 93.75%; fibers 0.002%; moisture 11.31%; lipids 0.5%; proteins 1.26% and ash 2.00%. The results indicated that the green banana of the ‘Terra Variety’ is viable for the process of obtaining banana flour, given that it is rich in starch and has a high caloric value.
