7.3.1 CPO Production Process. As reported by Igwe and Onyegbado [], CPO comprises a fatty acid ester of glycerol, also known as triglycerides, which contributes to the global need for edible oils and fats.It consists of roughly 50% saturated fats (mainly palmitic acid) and 40% unsaturated fats. The fat-soluble carotenoids (pigments) in palm oil are …
