Effects of drying methods on the characteristics of rambutan (nephelium lappaceum l.) seed fat: An optimisation approach

The pre-treatment of oilseeds prior to extraction process may affect oil yield and quality. The aim of this study was to investigate the effects of two drying methods on rambutan seed fat (RSF) yield and their oxidative stability, physicochemical properties, and crystal morphology. Response surface...
