Effects of the addition of hemp powder on the physicochemical properties and energy bar qualities of extruded rice

► We improved the nutritional properties of extruded rice by adding defatted and whole hemp powder. ► Increasing level of hemp powder increased bulk density and antioxidant activity. ► Rice added with whole hemp expands more than rice added with defatted hemp. ► The extruded rice + 40% whole hemp bar possessed poor hygroscopic properties. ► Energy bar from extruded rice + 20% whole hemp had highest acceptability.
