Abstract
The purple passion fruit (Passiflora edulis Sims f. edulis Sims) is a climacteric fruit highly sought after in the global market for its desirable organoleptic and nutraceutical characteristics, making it a potential export commodity.
However, its short postharvest life poses a challenge for international logistics.
This study focuses on extending the shelf life of export-grade passion fruits by implementing coatings made from natural waxes and silver-doped titanium dioxide nanoparticles (TiO2-Ag). The fruits, harvested under European market standards, underwent coating applications and were stored under different conditions; the results showed that the different treatments, particularly the combination of waxes and nanoparticles, effectively maintained fruit firmness and elasticity, and coatings also impact key parameters like total titratable acidity, suggesting a slowdown in metabolic processes.
These findings support the use of combined wax and nanoparticle applications as a promising strategy to enhance postharvest quality and prolong the shelf life of purple passion fruit.
