3.4. Effect of plant extracts on the organoleptic properties of banana fruits
Dipping of banana fruits in the effective plant extracts viz., Zimmu, tuber Z. scabra and chemical benomyl (0.1%) did not alter the organoleptic properties of banana. The overall, the quality of banana hands was improved as a result of these plant extract treatment (Table 4). However, treatment of banana fruits with root extract of A. calamus and leaf extract of P. zeylanica caused a mild to strong odor to develop which persisted for one month in cold storage. In all these treatments, the fruits remained green in color for up to one month of cold storage and ripened normally under room temperature condition (data not shown), but in the case of pathogen- alone inoculated control, the color broke from green to yellow in a month of cold storage.
Generally, loss of weight of fruits increased in all treatments throughout the storage and there were no significant difference in weight loss by treatment of banana hands with plant extracts(data not shown). The total soluble solids (TSS) have increased as ripening progressed. The TSS values of all treatments were within the range of 4.9–5.3 (oBrix) after cold storage and before subjected to natural ripening (data not shown).
