Effect of fruit treatment with 1-methylcyclopropene and Agro-Mos^® and storage conditions on postharvest quality of ‘Kyoto’ persimmon

This work was carried out to evaluate postharvest quality preservation of ‘Kyoto’ persimmon treated with 1-methylcyclopropene (1‑MCP; 1 µL L^-1) and a mannanoligosaccharide-based product (Agro-Mos^®; 5 mL L^-1) and left in cold storage (CS; 0.5±0.5°C/95±2% RH) and controlled atmosphere (CA; 2 kPa O₂ + 0.5 kPa CO₂ at 0.5±0.5°C/95±2% RH). The two fruit treatments (1‑MCP and Agro-Mos^®) and two storage conditions (CS and CA) were combined, resulting in eight treatments: CS, CS + Agro-Mos^®, CS + 1‑MCP, CS + 1‑MCP + Agro-Mos^®, CA, CA + Agro-Mos^®, CA + 1‑MCP and CA + 1‑MCP + Agro-Mos^®. Fruit quality was analyzed after 60 days of storage, followed by 1 and 3 days of shelf life (20±2°C and 60±5% RH). Fruit treated with 1‑MCP kept a greener skin color (higher values of hue angle and lightness) under both storage conditions (CS and CA), after 1 day of shelf life, but not after 3 days of shelf life. 1‑MCP and CA storage were effective to preserve flesh firmness and texture of the fruits.
CA conditions delayed skin browning after 1 day of shelf life.
After 3 days of shelf life, there was no difference between CA and CS conditions for skin browning.
Under CA, decay incidence was lower in fruit treated with 1‑MCP than with Agro-Mos^®. The results show that treatment with 1‑MCP associated with CA storage preserves postharvest quality of ‘Kyoto’ persimmon.
