Oil is one of the major components of date seed alongside dietary fibre carbohydrate protein moisture and ash. Therefore the present work focused on the extraction of oil from five varieties of date seed using Soxhlet extraction method and subsequently characterised their physicochemical and antioxidant properties accordingly. Oil extracted from the seeds ranged between 8 to 9.8 whereas the iodine values were between 48.7 to 55.5 g I2/100g. Furthermore oleic and lauric acids were revealed as the main fatty acids present in the date seed oil with LaOO (La: lauric acid; O: oleic acid) as the main triacylglycerol. The total phenolic content in the oil ranged from 7.96 to 17.72 mg GAE/g oil while the antioxidant activity expressed as EC‚‚ ranged from 5.17 to 17.18 mg/mL. Additionally the highest reducing activity was observed at 4mg/mL. Hence oil characteristics are dependent on the type of date thus indicating that different potential applications may be suggested.

Abstract

Oil is one of the major components of date seed alongside dietary fibre carbohydrate protein moisture and ash. Therefore the present work focused on the extraction of oil from five varieties of date seed using Soxhlet extraction method and subsequently characterised their physicochemical and antioxidant properties accordingly. Oil extracted from the seeds ranged between 8 to 9.8 whereas the iodine values were between 48.7 to 55.5 g I2/100g. Furthermore oleic and lauric acids were revealed as the main fatty acids present in the date seed oil with LaOO (La: lauric acid; O: oleic acid) as the main triacylglycerol. The total phenolic content in the oil ranged from 7.96 to 17.72 mg GAE/g oil while the antioxidant activity expressed as EC‚‚ ranged from 5.17 to 17.18 mg/mL. Additionally the highest reducing activity was observed at 4mg/mL. Hence oil characteristics are dependent on the type of date thus indicating that different potential applications may be suggested.
