Abstract
Abstract Despite their richness in bioactive compounds, green onion ( Allium cepa ) leaves are rarely valorized. This study compares several drying methods in terms of product quality and process performance: continuous (CCD), intermittent (ICD), interval starting accessibility (ISAD) while, freeze-drying (FD) was used as a control treatment. To achieve the same final water activity, the effective ISAD and ICD drying times were 10 and twice times lower than CCD. During drying, the core temperature of the onion leaves remained stable at 22 °C for ISAD while it reached the drying air temperature during (45 °C) during CCD and 34 °C for ICD. ICD and ISAD dried leaves had a total color difference between a maximum for CCD and a minimum for FD leaves. Moreover, CCD and ICD onion leaves had the highest loss of total phenolic content, while FD and ISAD achieved the highest preservation.
