An advanced device from Embrapa Meio Ambiente (SP) targets post-harvest fruit losses, potentially reaching 80% in certain species. This monitoring tool evaluates heat distribution during hydrothermal treatment, aiding in quality preservation and disease control to meet international market standards.
Researcher Daniel Terao highlights that heat treatment not only eradicates harmful microorganisms but also enhances the fruit's defenses. "Heat causes biochemical and physical changes that protect the fruit, such as closing micro-wounds in the wax layer, preventing the entry of opportunistic fungi," he says.
Embrapa's device ensures effective heat application from surface to pulp, crucial for pathogen elimination without quality compromise. Terao notes, "Without proper monitoring, there is a risk of the fruit suffering qualitative damage, such as changes in texture and flavor." This technology aligns with global health and quality benchmarks, crucial for Brazil's status as a leading fruit exporter.
The device, during hydrothermal treatment, uses heated water in rotation, with an electronic data logger and thermocouples for real-time heat monitoring. Despite Brazil's leadership in orange juice exports, post-harvest losses challenge its fruit sector, with issues like inadequate transport and ineffective treatments causing waste.
Embrapa's hydrothermal method offers a sustainable disease control alternative, reducing chemical reliance amid stricter pesticide residue limits in markets like the EU and the US. The device patent is filed, with Embrapa seeking partners for further development.
