  • Anthocyanin pigments from three pigmented rice varieties, Hongjinju, Sintoheugmi and Josaengheugchal pigmented by black color, were quantified to evaluate effects of transplanting and harvesting time during seed development. Hongjinju, a rice variety of grains pigmented by red color, contains only two kinds of anthocyanins, delphinidin and cyanidin. Meanwhile, delphinidin, cyanidin, and pelargonidin were identified in Sintoheugmi and Josaengheugchal. Anthocyanidin contents in pigmented rice variety Hongjinju under different planting times were decreased with prolonged harvesting times. The Sintoheukmi showed that cyanidin content was the highest among analyzed pigments during seed development. Two anthocyanins (cyanidin and pelargonidin) in Josaengheugchal recorded highest contents at 20 days after heading in three transplanting times. Cyanidin content was also slightly increased with prolonged transplanting time. Total anthocyanidin contents in Hongjinju were always lower than that of Sintoheukmi and Josaengheukchal. In two rice varieties, Sintoheugmi and Josaengheugchal, $a^*$ values were commonly slightly decreased by late transplanting and harvesting times. Changes of $a^*$ and $b^*$ values in waxy rice varieties, Sintoheugmi and Josaengheugchal varied more than those in Hongjinju. In Josaengheugchal, early harvesting before maturity showed lower brown rice yield and late harvesting in the each transplanting times resulted in highest brown rice yield.

  • This study was conducted to know the influence of air temperature and sunshine duration on yield, chemical component, pigment color difference and starch characteristics of two colored rice cultivars in the plain area of Yeongnam province in Korea. The $L^*$, $a^*$, and $b^*$ value of brown rice in Hongjinju and Josaengheugchal rice cultivars was significantly different at continuous cultivated years, 2015 and 2016. The $L^*$, $b^*$ value of two colored rice was significantly increased in 2016 compared to 2015. The $a^*$ value of Josengheugchal rice cultivar was also significantly higher at 2016 than at 2015. It can be noticed the $a^*$, $b^*$, $L^*$ values in Josaengheugchal varied more than those in Hongjinju. Air temperature during ripening period in 2016 was higher than 2015, especially minimum temperature was too high to proper maturation for rice quality. In Josaengheugchal rice cultivar, sunshine duration after heading was longer in 2016 than in 2015. On the contrary, Hongjinju rice cultivar was ripened under condition of insufficient sunshine duration in 2016. The short growing duration by high temperature and long shiny duration made the lack of pigment for Josaengheugchal brown rice. In Hongjinju rice cultivar, shorten sunshine duration and higher night temperature were the source of the pigment deficiency. The grain size of rice which produced in 2016 was bigger than that of 2015 in both rice cultivars. The 1,000 grain weight of rice from 2016 was also bigger than that of 2015. Head rice ratio was high in the rice cultivars produced in 2015. Protein of milled rice in 2016 was more decreased than that of 2015 in Josaengheugchal rice cultivar, it showed reverse result in Hongjinju rice cultivar. Amylose contents of milled rice in 2016 were more decreased than that of 2015 in Hongjinju rice cultivar. Branch chain length distribution of amylopectin was shown a distinct difference between Josaengheugchal and Hongjinju rice flours by each produced year. Josaengheugchal rice cultivar produced in 2015 had a higher amount of short chains than that of 2016 rice starches. In Josaengheugchal rice cultivar, the pasting temperature and peak, trough, breakdown, final viscosity increased in rice flour which produced at 2016, whereas the setback viscosity and peak time showed lower value than those of rice from 2015. The most pasting properties (except of setback viscosity) of rice starch in Hongjinju rice cultivar grown in 2015 were higher than those of rice cultivar produced in 2016.

  • This study was conducted to explore the quality characteristics of colored rice depending on the cultivars (Jeogjinu, Josaengheugchal, Joeunheukmi, Heukjinjubyeo, Hongjinju, Heukjinmi, Geongganghongmi) for porridge. The moisture, crude protein, lipid, ash, amylose and damaged starch contents of colored rice ranged from 10.05~11.23%, 7.72~8.69%, 2.68~3.26%, 1.62~1.88%, 6.29~20.31% and 5.06~8.26%, respectively. The highest moisture (11.23%), crude protein (8.69%), lipid (3.26%) and ash (1.88%) contents of colored rice were detected in Heukjinjubyeo, Joeunheukmi, Josaengheugchal and Heukjinmi, respectively. The lowest amylose and damaged starch contents of colored rice were detected in Josaengheugchal and Joeunheukmi, respectively. In general, the water binding capacity, water solubility and swelling power of Heukjinmi were greater than those of the other cultivars. The investigation of the pasting properties (peak, trough, break down, final and setback viscosity, peak time, pasting temperature) of colored rice indicated a low value in Josaengheugchal. The lowest hardness (13,673.25 g) of colored rice was observed in Heukjinjubyeo while the highest digestibility (5.44 glucose mg/g) of colored rice was observed in Josaengheugchal. These results indicated that Josaengheugchal are suitable cultivars for porridge.

  • 'Josaengheugchal', a new blackish purple pigmented glutinous japonica rice cultivar, was developed by the rice breeding team of Department of Functional Crop, NICS, RDA in 2004. This cultivar was derived from a cross between 'Tohoku 149' as black glutinous source and 'Sx 864' as purple colored rice in 1992 and 1993 winter season, and selected by pedigree breeding method until $F_6$ generation. As a result, a promising line, YR15907-6-8-1-5, was advanced and designated as the name of 'Milyang 194' in 2001. The local adaptability test of 'Milyang 194' was carried out at seven locations from 2002 to 2004 and it was named as 'Josaengheugchal'. 'Josaengheugchal' is an early maturing cultivar and has 71 cm culm height. It has higher anthocyanian content compared with 'Heugnambyeo'. It is moderately resistant to leaf blast but susceptible to other disease and insect pests. The yield potential of 'Josaengheugchal' in brown rice was about 4.21 MT/ha at ordinary fertilizer level in local adaptability test. This cultivar would be adaptable to the plain paddy field of middle, Honam, and Yeomgnam in Korea under ordinary and double cropping system.

  • In this study, we examined the quality of fish cakes prepared using the flour obtained from the following different rice varieties: Baekogchal, Dodamssal, Hangaru, Jeogjinju 2, Josaengheugchal, Saeminyeon, Saeilmi, and Shingil. The moisture content of the fish paste containing rice flour ranged from 67.40% to 69.90%, and was highest in the paste prepared using Baekogchal flour. The lipid and protein contents of the paste ranged from 0.05% to 0.43% and 11.36% to 11.69%, respectively, whereas the carbohydrate content was between 10.36% and 12.32%, and was highest in the paste prepared using Jeogjinju 2 flour. Fish cakes prepared using the flour from Baekogchal, Jeogjinju 2, and Josaengheugchal rice were found to have the hardest consistency. Sensory evaluations indicated that fish cakes prepared using Shingil flour had the best texture. Furthermore, the total polyphenol content was significantly higher in the fish cakes prepared using Josaengheugchal flour (165.12 mg GAE/100 g), whereas the DPPH and ABTS radical scavenging activities were significantly higher in the fish cakes prepared using Josaengheugchal flour (39.37 and 175.37 mg TE/100 g, respectively). In conclusion, we confirmed that the quality of fish cakes is affected by the characteristics of the flours obtained from different rice varieties. Among the varieties assessed, the quality of Shingil and Josaengheugchal varieties was suitable for preparing rice-containing fish cakes.

  • The purpose of this study was to investigate antioxidant characteristics and anti-adipogenic effects of colored rice and brown rice extracts in 3T3-L1 adipocyte depending on cultivar (Josaengheugchal, Heugjinmi, Hongjinju, Geongganghongmi, Seolgaeng, Milyang 320, Sindongjin, Baegjinju). Colored rice and brown rice was extracted with 100% ethanol, followed by the analysis of polyphenol, flavonoid, anthocyanin, antioxidant, and anti-adipogenic activity. Total polyphenol and flavonoid content ranged from 6.86~314.08 mg GAE/g and 1.47~56.88 mg CE/g the highest total polyphenol and flavonoid content was observed in Heugjinmi cultivar. Anthocyanin composition was analyzed by HPLC, cyanidin-3-gluoside and peonidin-3-glucoside was found in black rice including Josaengheugchal and Heugjinmi. Also, the ABTS and DPPH radical scavenging activity of colored rice cultivars was higher than that of brown rice cultivars, the highest ABTS radical scavenging activity also was observed in Heugjinmi (128.20 mg TE/g). The anti-adipogenic effects of colored rice and brown rice extracts on differentiation of 3T3-L1 preadipocytes evaluated that extracts of Heugjinmi cultivar significantly reduced intracellular lipid accumulation. These results provide valuable information for the use of Korean colored rice cultivar as a functional food materials relative to anti-obesity.

  • Rice is a staple food for more than 50% of the world's population. Embryo comprises only 2 to 3% of the weight distribution of the entire pericarp but has higher concentration of vitamins, proteins, and essential fatty acids than the other parts of grains. Moreover, ${\alpha}$-tocoperol, ${\gamma}$-oryzanol, phytic acid and ${\gamma}$-aminobutric acid that have nutraceutical value are abundant. Increasing the volume of embryo assures the fortification of nutritional value of rice grain. We developed new black waxy giant embryo rice, Milyang 263 by crossing Josaengheugchal, a black waxy rice variety, and $ge^t$, a giant embryo mutant generated by tissue culture. The nutrient contents and physical properties of Milyang 263 were compared with several giant embryo mutants and normal embryo rice varieties. Changes in the nutrient properties after germination were also observed. Results indicated that this new black waxy giant embryo rice, Milyang 263, offers a promising source for improving nutritional quality of rice especially anthocyanin, essential minerals, and GABA.

  • Seeds of colored rice generally have high anthocyanin and flavonoid content but some cultivars have low seed germination rate. This defect poses unstable seedling establishment in nursery bed. The seed gravity variations of 10 colored rice varieties and its effect on germination, seed soaking duration and their optimum seeding rates for seedling raising in machine transplanting were investigated in the experiment. Based on seed gravity distribution of the 7 black- and 3 red-colored rice varieties at three levels of seed gravity (1.0<, 1.0~1.06, 1.06>), the black colored seeds such as Josaengheugchal and Sinmyungheugchal had high amount of specific gravity of below 1.0 ranging from 86~ 96%, while they had only 3~13% of seeds in specific gravity above 1.06. Sintoheugmi, Heugjinju, Heugnam, Heugkwang had various mass of seeds, showing 29~44% for specific gravity of below 1.0, 24~39% for 1.0~1.06 and 25~45% for above 1.06. On the other hand, the red colored rice such as Hongjinju, Jeogjinju and Geonkanghongmi had high percentage of specific gravity of above 1.06 with 84~86% while they had only 9~12% of specific gravity below 1.0 similar to Ilmibyeo of noncolored rice. The black colored seed generally showed low germination percentage, slow germination speed and long mean germination time, and low water absorption rate as compared with seed of the red colored rice which was similar to those of Ilmibyeo used as a control cultivar. The black colored seeds took 2~4 days longer seed soaking duration than the red colored rice before germination. This was related to high seed amount of specific gravity below 1.0 in black colored rices. The high amount of seed gravity above 1.06 in the colored rice seeds was positively correlated with percentage of germination, germination speed and mean germination time, ripened grain ratio and water absorption. Seed gravity distribution effect were less pronounced between back- and red- colored seeds in seedling emergence. The black colored rice has slightly lower normal seedling emergence rate than the red colored rice and Ilmibyeo in the seedbed soil due to high percentage of ungerminated seed. Normal seedling emergence rate of the black colored rice in the seedbed was 75.2~82.2% for 10-day old seedling and 85.3~ 90.9% for 30-day old seedling which was lower by 4.5~ 8.0% and 0~3.3%, respectively, than the red colored rice. Based on the normal seedling number per tray of Ilmibyeo for seeding rate of 10-day and 30-day old seedlings, the recommended seeding rate of black colored rice is 200~ 220g seeds for the 10-day old seedling and 110~130g for the 30-day old seedling in transplanting rice while the seeding rate of the red colored rice was 220g seeds for the 10-day old seedling and 130g for the 30-day old seedling.
