Implication

Experimental study demonstrates improved quality retention and reduced microbial load in postharvest tomatoes, indicating ultrasound is a viable approach to extend fresh fruit shelf-life.

Key Points

To optimize postharvest ultrasound processing parameters to preserve physical quality attributes, enhance phenolic content, and reduce microbial contamination in stored tomatoes.
Treated whole tomatoes (Solanum lycopersicum, cv. Zinac) with ultrasound power levels from 10% to 100% at 45 kHz for durations ranging from 1 to 19 minutes.
Optimized parameters using a central composite rotatable design (CCRD) coupled with response surface analysis targeting color, texture, and total phenolic content (TPC).
Monitored fruit color, firmness, TPC, and microbial load over 15 days of postharvest storage at 10°C relative to untreated control fruit.
Identified optimal ultrasound treatment conditions at 55% power for 10 minutes, 80% power for 15 minutes, and 100% power for 19 minutes.
High-power ultrasound treatments significantly delayed color progression and texture loss while increasing total phenolic content and lowering microbial load compared to untreated controls across 15 days of storage at 10°C.
