Palm fatty acid, specifically referring to Palm Fatty Acid Distillate (PFAD), is a byproduct generated during the refinement process of converting crude palm oil (CPO) into cooking oil. It's essentially one of the waste products resulting from this process.
Understanding Palm Fatty Acid Distillate (PFAD)
PFAD is a mixture of various fatty acids and other components derived from palm oil. Here's a breakdown:
- Origin: It is a residue from refining crude palm oil.
- Composition: It mainly consists of:
- Free fatty acids
- Partial glycerides (mono- and diglycerides)
- Other minor components
- Traditional Use: Historically, PFAD has been relegated to low-value applications, such as:
- Raw material for low-grade soap production
- Biofuel production
Upgrading PFAD's Value
Due to its low economic value in its traditional uses, research has focused on upgrading PFAD for better applications:
- Esterification: A key method is converting PFAD into monoglycerides via esterification, a process that involves reacting fatty acids with glycerol. This upgrade enhances its economic value.
- Potential Applications: This monoglyceride can be used in:
- Food industry
- Cosmetics
