Abstract:

Housui pears were used as the raw materials to investigate the preservative effects of modified atmosphere package (MAP) bags coupled with 1-MCP treatment at different concentrations and near-freezing point storage. Results indicated fruits could maintain excellent quality in 0.02 mm PE and 0.04 mm PVC bags coupled with 0.5 μL/L 1-MCP treatment. In addition, Housui pears exhibited high CO2-resistant capability and no harm was observed under the condition of 3.0%-4.0% CO2. Fresh firmness was negatively correlated with polygalacturonase (PG) activity (P ≤ 0.05). Housui pear could maintain excellent quality and flavor for 150 days at - 1 ℃, and approximately 120 days at 0 ℃.

Key words: Housui pear, modified atmosphere package(MAP), 1-MCP, near freezing storage, quality
