Walnut oil contains high levels of linoleic acid (PUFA) and oleic acid (MUFA), which contribute to low viscosity, good cold flow, and easy transesterification. However, high PUFA content slightly lowers oxidative stability and cetane number compared to more saturated oils. Despite this, walnut biodiesel still meets fuel quality standards with proper processing. The GlobeCore USB system optimizes conversion and can incorporate stabilizers if needed, ensuring a clean-burning, engine-safe fuel. The yield from walnut oil is high due to its triglyceride-rich composition.
