Chrysophyllum albidum has been reported to be a medicinal plant due to its high Vitamin C content and the presence of phytonutrient such as phenols and flavonoids. Freshly harvested African star apple fruits were processed and separated into pulp, seeds and peel and were dried between 60°C to 65°C using different forms of drying technology, specifically Oven drying and Vacuum drying. The dried products were subjected to proximate, elemental and vitamin C analysis. Also, the total phenolic and flavonoid content of the products were determined and their antioxidant potentials explored. Results showed that samples that were vacuum dried retained their nutritional composition, phytonutrient content and antioxidant potentials better than samples that were oven dried. Also, results showed that the seeds appeared to contain more fibre, ash, protein and fat content than all other fruit parts. However, the pulp contained more moisture and Vitamin C content while the peels were the richest in carbohydrates. Results also revealed that the pulp had the highest phytonutrient content and as such exhibited more antioxidant potentials than all other fruit part.
