A comparative study of nutrient compositions, phytochemicals, and antioxidant activities of two dehulled hemp seed cultivars harvested from different regions in the Republic of Korea

초록

Hemp (Cannabis sativa L.) seeds are receiving considerable attention because of their potential applications in food industry. This study compared nutrient components and antioxidant activities of dehulled hemp seeds from 'Ordinary' and 'Cheongsam' varieties cultivated in various regions in the Republic of Korea to elucidate their potential for food applications. Results showed that dehulled hemp seeds were rich sources of protein, fat, mineral, and tocopherol contents, influenced significantly by both hemp genotype and environmental factors. Both 'Ordinary' and 'Cheongsam' dehulled hemp seeds possessed a favorable amino acid pattern, with high amounts of essential amino acids. Additionally, both cultivars exhibited high levels of unsaturated fatty acids, notably linoleic acid and alpha-linolenic acid, with a beneficial omega-6/omega-3 ratio for human health. Both cultivars possessed high levels of phenolic compounds and antioxidant capacities, especially cv. 'Cheongsam'. Overall, 'Cheongsam' hemp seeds exhibit exceptional nutrient components and antioxidant potential, showing promise in various food applications.
