Abstract

This study aimed to characterize and compare pili (Canarium ovatum Engl.) pulp oil from two different varieties of pili fruits in Bicol, Philippines namely M. Orolfo and Orbase varieties for possible utilization into oil-based products. The effects of varietal differences in pili fruits on physical, chemical and quality characteristics of its pulp oil were determined. These two oils were also compared with control oils, commercially available coconut oil and extra virgin olive oil. Pili pulp oil from M. Orolfo had dark color while Orbase had color close to extra virgin olive oil. The two varieties did not significantly differ from each other in terms of refractive index, moisture and volatile matters, acid value, iodine value, saponification number and percent unsaponifiable matter but significantly differed from coconut oil and extra virgin olive oil. On the other hand, the two varieties significantly differed from each other in terms of peroxide value, Vitamin A and α-tocopherol contents. In terms of fatty acid profile, high amounts of palmitic acid were determined in both pili varieties (19-25%) compared with coconut oil (6.34%). Oleic acid in Orbase was 71.5% while M. Orolfo had 58.1%, which are comparable with extra virgin olive oil (77.9%). Pili pulp oils from M. Orolfo and Orbase can be utilized into oil-based products because its chemical and quality characteristics are within the standard. Both can be stored for a longer period of time and healthier in terms of fatty acid composition and natural antioxidant content.
