Effect of 1-MCP and KMnO4 treatments with different packaging on quality preservation of golden delicious apples.

This study explored the impact of three packaging materials (wooden boxes, corrugated fiber boxes, shrink-wrapped boxes) combined with two ethylene scrubbers (1-MCP, KMnO) on the shelf life of Golden Delicious apples.
