The industrial processing of passion fruit (Passiflora edulis f. flavicarpa) generates large amounts of lignocellulosic residues that are of great economic, scientific, and technological interest. This study investigated different pretreatments – aqueous, acidic and basic – aided by ultrasound. It also verified their influence on the chemical and physical aspects of passion fruit peel and on the yield of carbohydrates, 5-hydroxymethylfurfural (HMF) and furfural (FF). The pretreatments followed a complete factorial experimental design to obtain the optimal conditions varying in concentration (2.5 % and 5 % HCl; 4 % and 8 % NaOH) and time (0.5 and 1 h) for carbohydrate yield and increased accessibility to cellulose and hemicellulose. These results were analyzed by HPLC, FT-IR and X-ray diffraction analysis. Optimized conditions for the pretreatment were 2.5 % HCl, 4 % NaOH and aqueous with a sonication time of 1 h. The pretreatments tested increased the efficiency of the hydrolysis. The highest yields of glucose (5.05 g/L), HMF (0.09 g/L), and FF (0.99 g/L) were recorded from the hydrolysis pretreated with HCl 2.5 % at 1 h. This study demonstrated the potential of using passion fruit peel in biorefinery processes, adding value to waste and promoting sustainability. |
