EXTRACTION OF FRUCTO-OLIGOSACCARIDE COMPONENTS FROM BANANA PEELS
The extraction of fructo-oligosaccharides from banana peels was aimed in this study. Experimental parameters were particle size, solvent type, temperature (40-600C) and time (10-210 minutes). 30% of yield was obtained when optimum sized peels (2*7*10 mm) were extracted with pure acetone at relatively low temperature (500C) during 90 minutes. Total fructo-oligosaccharide content was found nearly 33% of the sugar components of the extracts, and nystose was absent. The degree of polymerization was lower than those of other fructooligosaccharide containing plants (<6). It was concluded that GRAS-statued fructo-oligosaccharides can be produced from a solid waste, a banana peel.
