Acorn oils are also anexcellent source of tocopherols, since it was found thattocopherol contents in acorn oils range from 1440 to1783 mg/kg oil, which were much higher than those reportedfor other species such as olive (240 mg/kg)

As regards the physical properties, acorn oilsshowed a refractive index ranging from 1.449 to 1.453 [21].*ese values are similar to those reported previously by [2]for acorn oils from other species and comparable to othervegetable oils such as olive oil 1.4677–1.4705.

*e iodinevalue represents the degree of unsaturation of the oils andthe fat, and the more unsaturation leads to a higher iodinevalue [29]. *e iodine value for acorn oil reported by [2] was75–88 g/100 g, which is comparable to the value of olive oil75–94 g/100 g. *e highest iodine value of acorn oil wasreported to be 129.6 g/100 g [21].

]. *esaponification values of acorn oils range from 160.3 to220 mg KOH/g. *e saponification value of acorn oils iscomparable to that of olive oil (184–196 mg KOH/g) [2]. *isrelatively high saponification value indicates that oils holdfatty acids with a high number of carbon atoms

Acorn oil presents good nutritional quality,and its flavor is comparable to that of olive oil
