A comparative investigation on the effect of thermal treatments on the mechanical properties of oil palm fruitlet components

An assessment of the mechanical properties was employed as the principal yardstick to quantify the physical attributes of oil palm fruitlet components before and after being subjected to thermal treatment process. Two industrial-scale thermal treatment methods were considered; horizontal sterilisati...
