  • 'Superjami', a new blackish purple pigmented rice cultivar was derived from a cross between 'CG2-3-5-1-6-1' (developed from a cross between 'Heugjinjubyeo' and 'Suweon 425') as high amount of C3G (Cyanidin 3-glucoside) and 'Daeribbyeo 1' with large seed size in 2003, and selected by pedigree breeding method until $F_7$ generation. As a result, a promising line, 'SR28721-7-9-3-1-2-1', was developed and designated as the name of 'KNOU 5' in 2008. This variety has about 125 days to heading after sowing and has 74.9 cm culm height. The ratio of fertility of 'Superjami' was about 89.6% and 1,000-grain weight was about 26.2 g. It was 1.5 times heavier than 'Heugjinjubyeo'. 'Superjami' has 10 times higher C3G content compared with 'Heugjinjubyeo'. The yield potential of 'Superjami' in brown rice was about 6.3 MT/ha at ordinary fertilizer level in local adaptability test.

  • Commercial Korean domestic and foreign intermediate food materials (IFMs) of blueberry, Aronia, oat, sweet pumpkin, and ginger were purchased to compare their functional properties, including total phenolic content (TPC), total flavonoid content (TFC), total anthocyanin content (TAC), and antioxidant capacity. Each IFM was extracted using 80% (v/v) methanol for the analyses. The TPC (mg gallic acid equivalent/100 g dried sample) and TFC (mg catechin equivalent/100 g dried sample) levels in domestic blueberry (TPC, 2,916 ± 200; TFC, 1,327 ± 31) and sweet pumpkin (TPC, 476 ± 20; TFC, 23 ± 32) IFMs were significantly higher than those in the foreign IFMs. In the case of TAC (mg cyanidin-3-glucoside/100 g dried sample), the level in domestic blueberry IFM (949 ± 57) was significantly higher than that in the foreign product. Among the domestic IFMs, the antioxidant capacities (mg vitamin C equivalent/100 g dried sample) of blueberry, sweet pumpkin, and ginger were 7,057 ± 321, 311 ± 8, and 3,321 ± 109, respectively, being significantly higher than those of their foreign counterparts, based on the ABTS radical scavenging assay. In the DPPH radical scavenging assay, foreign Aronia (12,667 ± 437) and ginger (2,067 ± 99) IFMs showed significantly higher levels of free radical scavenging activity than did the domestic IFMs. These results provide basic information regarding the functional properties of Korean domestic IFMs, compared with their foreign counterparts.
