Smoke-water obtained via different biotics: a cost-effective and safer approach to biochemically sound banana ripening with prolonged shelf-life

Abstract

This study was conducted to investigate the efficacy of smoke-water obtained from biotics, for example coconut shells, rice husk, and pine cones on banana ripening, and compared with calcium carbide. Bio-chemical composition and remarkable bactericidal effect towards ATCC cultures of Escherichia coli, Staphylococcus aureus, and Bacillus cereus discovered the biological safety of the smoke-water in all collected smoke-water samples. Further, inductively coupled plasma mass spectrometry (ICP-MS) was carried out to investigate heavy metals; however, no traces were found in all collected samples. Consequently, it is proposed that heavy metal-free smoke-water obtained from various biotics series might be employed as ultrasafe fruit ripening as compared to calcium carbide (CaC₂) that was found with heavy metal traces.
