In this study three popular regionally grown rice varieties (Bario brown and white) were compared with three of the most popular and highly marketed imported rice varieties (black glutinous and basmati rice) in Penang region of Malaysia. Rice samples were evaluated for amino acids fatty acids minerals heavy metals and dietary fiber composition. Overall amino acids content among all the rice samples were comparable to each other. Results with regard to minerals showed potassium to be high in brown rice (197.41 mg/100g) while magnesium was recorded to be high in black rice (107.21 mg/100g). Heavy metals such as cadmium nickel mercury and lead though present they were in negligible amounts. Among all the rice varieties investigated the total saturated fatty acid and unsaturated fatty acid content was highest in black rice (5.89). The soluble dietary fiber was higher in white rice (16.39) whereas insoluble dietary fiber was high in brown (16.51) and black rice (14.49) respectively. Results generated from this study is anticipated to benefit both the health wary consumers (based on their potential nutritional attributes) as well as the local food industries to choose the best rice variety while developing novel rice based food products.

Abstract

In this study three popular regionally grown rice varieties (Bario brown and white) were compared with three of the most popular and highly marketed imported rice varieties (black glutinous and basmati rice) in Penang region of Malaysia. Rice samples were evaluated for amino acids fatty acids minerals heavy metals and dietary fiber composition. Overall amino acids content among all the rice samples were comparable to each other. Results with regard to minerals showed potassium to be high in brown rice (197.41 mg/100g) while magnesium was recorded to be high in black rice (107.21 mg/100g). Heavy metals such as cadmium nickel mercury and lead though present they were in negligible amounts. Among all the rice varieties investigated the total saturated fatty acid and unsaturated fatty acid content was highest in black rice (5.89). The soluble dietary fiber was higher in white rice (16.39) whereas insoluble dietary fiber was high in brown (16.51) and black rice (14.49) respectively. Results generated from this study is anticipated to benefit both the health wary consumers (based on their potential nutritional attributes) as well as the local food industries to choose the best rice variety while developing novel rice based food products.
