Effect of 1‐Methylcyclopropene on the Quality of Fresh‐cut Apple Slices

Abstract

ABSTRACT: The objective of this project was to treat fresh‐cut apple slices with the ethylene inhibitor 1‐methylcyclopropene (1‐MCP) to retard ethylene‐induced deterioration and senescence and to prolong the shelf life of such products. Intact Braeburn and Pacific Rose apples were treated at different times with 1‐MCP, cut, and stored at 0 °C. Samples were analyzed initially and then weekly for ethylene, respiration, flesh firmness, tissue color, titratable acidity, and soluble solids content during 5 wk of storage. 1‐MCP treatment was effective in reducing ethylene production, respiration, and loss of firmness and color of slices when applied to whole apples directly after harvest. Total sugar and acidity levels were not affected significantly.
