The current study was aimed at utilising fruit wastes generated after pectin extraction for assessing their antimicrobial and antioxidant properties. Total soluble proteins (TSP) and heat-stable proteins (HSP) were extracted from wastes of Musa sp., Citrus limetta, Citrullus lanatus, Solanum lycopersicum and Psidium sp. The HSP from S. lycopersicum waste could suppress the growth of Escherichia coli whereas Musa sp. and C. limetta HSP could inhibit the growth of Pseudomonas sp. C. limetta HSP was most effective in supressing the growth of Fusarium oxysporum relative to the other test samples. No pathogens responded towards the HSP of C. lanatus. High antioxidant activity [Ferric Reducing Antioxidant Power (FRAP)] along with high phenolic levels were observed in Psidium sp and Musa sp. fruit residues. Adopting appropriate extraction methods for active biomolecules from biodegradable wastes may pave the way for neutriceutical and pharmaceutical applications.
