|
The physicochemical characteristics of sorghum according to variety and seeding period were evaluated. The moisture, crude ash, fat, protein, and carbohydrate contents of sorghum were significantly different according to variety and seeding period. Lightness and yellowness of sorghum increased significantly as seeding period was delayed, whereas redness decreased. Water binding capacity of sorghum increased as seeding period was delayed. Swelling power of Hwanggeumchal was decreased as seeding period was delayed, whereas Donganme increased. Total polyphenol contents of Hwanggeumchal and Donganme were 22.16∼32.93 and 20.93∼38.25 mg gallic acid equivalents/g, and flavonoid contents were 12.27∼18.78 and 11.50∼21.64 mg catechin equivalents/g, respectively. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity was 13.70∼26.96 and 14.35∼35.17 mg Trolox equivalents (TE)/g, and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity was 17.15∼33.58 and 14.37∼41.72 mg TE/g, respectively. Total polyphenol and flavonoid contents as well as radical scavenging activity of sorghum increased significantly as seeding period was delayed.
