Online Published on 4 January, 2024. Abstract The study was undertaken to evaluate the impact of glycerine on drying process of cut foliage of silver oak (Grevillea robusta L.). Two methods of glycerinisation, namely uptake and full dip, were used, and different concentrations of glycerine (10%, 20%, and 40%) were tested. The overall acceptability of dried foliage was assessed, with a higher score indicating better quality. The results showed that full dip method achieved the highest score for overall acceptability (3.36) compared to uptake method. Among concentrations of glycerine, 40% was identified as the optimum for drying process. The maximum score obtained for overall acceptability of dried foliage was 4.98, indicating a relatively high level of satisfaction with quality. Using the full dip method and a glycerine concentration of 40% can result in dried foliage with good overall acceptability. These findings can be useful for improving the drying process of silver oak foliage and enhancing its quality for various applications.
