Fumigation of sweet cherries with low levels of thymol and acetic acid to reduce postharvest brown rot and blue mold rot.

This study reports the effects of essential oils and short-chain organic acids on the quality of sweet cherries (Prunus avium cv. Hedelfingen). Sweet cherries were inoculated with the conidia of Monilinia fructicola and Penicillium expansum, then fumigated with three levels of thymol or acetic acid for 10 min before cold storage. After 13 d at 10 deg C, sweet cherries fumigated with 10 mg thymol/litre significantly reduced brown rot from 21 to 12%, but had no effect on reducing blue mould rot. Fumigation with 6 or 10 mg acetic acid/litre significantly reduced blue mould rot from 16 to 2%, but had no effect on reducing brown rot. Fumigation did not have any effect on the firmness, total soluble solids and titratable acid of the sweet cherries. Fumigation with 2 or 6 mg thymol/litre did not accelerate stem browning compared with the control, but fumigation with 10 mg thymol/litre caused almost total stem browning. Fumigation with acetic acid showed no impact on discoloration of the stems. Thus, fu

migation with acetic acid or thymol at low concentrations has a potential use for postharvest decay control without adverse effects on fruit quality.
