OPTIMASI PAPARAN OZON BERBASIS DIELECTRIC BARRIER DISCHARGE UNTUK MEMINIMALKAN DEGRADASI TEKSTUR TOMAT

---

This study aims to optimize ozone exposure based on Dielectric Barrier Discharge (DBD) to extend the shelf life and maintain the textural quality of postharvest tomatoes. The DBD system was designed using a coaxial configuration with voltage variations ranging from 3.5 to 6.5 kV to determine the most efficient ozone concentration. Measurements using an ozone analyzer indicated that a voltage of 6.5 kV with a 1.8 mm electrode gap produced the highest ozone concentration of 8.8 g/Nm³. Tomatoes treated with ozone immersion for 10–15 minutes exhibited more stable firmness (10–12 Pa) and lower weight loss (0.5–1.0%) compared to the control group, which reached 1.8% after 14 days of storage. Ozone treatment also slowed respiration and microbial growth without damaging the fruit tissue. Therefore, the DBD-based ozone technology proved to be an effective and environmentally friendly postharvest preservation method to minimize texture degradation and extend the shelf life of fresh tomatoes.
