Oil Absorption Capacity (OAC) was determined using a modified method based on the method of . 0.5g sample was mixed with 6ml of corn oil in a pre-weighed centrifuge tube. The mixture was stirred with a brass wire for 1 minute, then left to stand for 30 minutes. After centrifugation (3000 rpm, 25 minutes), the separated oil was removed and the tube was drained for 25 minutes before reweighing. OAC was calculated as the grams of oil bound per gram of sample (dry basis).
