  • This study investigated the quality characteristics of black soybean sediments to diversify the availability of soybean. The cooking method selected for black soybean sediment preparation was a pressure cooking process without soaking, considering the isoflavone content. The black soybean sediments were prepared by the addition of 0, 10, 30, 50 and 100% (w/w) black soybean. When 0% to 100% black soybean was added to the black soybean sediments, the moisture and crude protein contents increased from 53.17% to 54.41% and from 12.07% to 21.68%, respectively. The total isoflavone content of the black soybean sediments was increased from 2.69 ㎍/g to 696.09 ㎍/g, respectively, by the addition of black soybean. The anthocyanin content of the black soybean sediments ranged from 279.29 ㎍/g to 387.8 ㎍/g by the addition of black soybean. The total polyphenol content and the total flavonoid content of the black soybean sediments range from 1.72 mg/g to 2.00 mg/g and 0.89 mg/g to 0.92 mg/g, respectively, by the addition of black soybean. Given the isoflavones, total polyphenol, and anthocyanin content of the black soybean sediments, it is appropriate that the ratio of added black soybeans is at least 50% after the pressure-cooking process, regardless of soaking.

  • This study aimed to evaluate the quality characteristics of Tteokgalbi with 1% (w/w) black rice bran only (T1), or with black rice bran and one of the following four types of organic acid: ascorbic acid (T2), citric acid (T3), tartaric acid (T4), or maleic acid (T5) as a substitute for caramel colorant. Tteokgalbi with only black rice bran showed the highest (p<0.05) values of moisture content and water holding capacity (WHC), while there were no significant differences in protein content, fat content, ash content, and thiobarbituric acid reactive substance (TBARS) values in treatments and controls (p>0.05). All the treated samples with any one of the four organic acids showed lower pH than controls (p<0.05). The lightness and redness of Tteokgalbi treated with any one of the four organic acids and black rice bran were higher than those of T1. The volatile basic nitrogen (VBN) values of T4 and T5 were higher than those of the other treatments (p<0.05). With regards to sensory characteristics, T1 and T2 showed overall acceptability similar to that of the controls (p>0.05). The results reported in this study show that Tteokgalbi with black rice bran and any one of the four organic acids listed above not only improved quality characteristics in cooking loss, WHC, lipid oxidation but also could successfully replace the synthetic caramel colorant. Overall, the most satisfactory results were obtained by adding black rice bran and ascorbic acid.

  • In this study, the quality characteristics of jelly with black garlic (0, 10, 20, and 30%) were evaluated. The pH of jelly with black garlic decreased according to the amount of black garlic added. The sugar content of the jelly increased significantly with added black garlic. Lightness, redness, and yellowness decreased with increasing black garlic content. Moreover, the textural properties, which included hardness, springiness, cohesiveness, gumminess, and chewiness decreased in jelly that contained black garlic compared to the controls. Additionally, the antioxidant activity of jelly that contained black garlic increased in a concentration dependent manner. The $IC_{50}$ values of the DPPH radical scavenging activity for jelly that contained 10, 20 and 30% black garlic were 132.47, 50.97, 40.06, and 30.41 mg/mL, respectively. The $IC_{50}$ values of the hydroxyl radical scavenging activity of jelly decreased as the black garlic concentration increased. Finally, sensory results showed that the scores of over-all preference and buying intention for jelly with 20% black garlic were the highest.

  • The principal objective of this study was to evaluate the quality characteristics of black ginseng jelly prepared with different 5 levels(0, 0.5, 1.0, 1.5, and 2.0%) of black ginseng extract. We assessed the ginsenosides level of white and black ginseng for comparison between white and black ginseng. And we conducted the pH, sugar content, Hunter's color values, the mechanical characteristics and sensory evaluation of black ginseng jelly samples. The levels of ginsenoside $Rg_3,\;Rh_1$, and $Rh_2$ of black ginseng were higher than those of white ginseng. The more black ginseng extract was increased, the sugar contents of black ginseng jelly were significantly increased(p<0.05). We noted that the luminance and Hunter's b values of jelly samples were decreased according to black ginseng extract was increased, but in Hunter's a values 0.5% black ginseng jelly was the highest of the all. With regard to the mechanical properties of the black ginseng jelly samples, the score of hardness, gumminess and chewiness were significantly increased. In color, taste and overall quality, the score of jelly with 1.0% black ginseng extract was significantly increased than those of the all.

  • The effects of raw and processed small black soybean powders on dietary fiber content and gastrointestinal function in rats were investigated. The crude oil, protein, and ash contents of raw small black soybean powder were not significantly different from those of processed small black soybean powders. The germination process increased soluble and insoluble dietary fiber contents significantly, as compared to raw small black soybean powder. The germinated small black soybean powder diet led to a significantly different food intake than the basal diet in both normal and loperamide-induced constipated rats. The body weight gains of the experimental groups, however, were not significantly different from that of the basal diet groups for both the normal and loperamide-induced rats. The gastrointestinal transit times and fecal weights for normal and loperamide-induced rats consuming the processed small black soybean powder diet were significantly different from those on a basal diet. These results suggest that the processes of cooking and germinating the small black soybean might contribute to acceleration of fecal excretion in both experimental normal and constipation model rats.

  • The changes in components and biological activities of doenjang samples prepared with black soybeans and fermented with Bacillus subtilis SCB were investigated. The amino nitrogen (A-N) contents of samples increased with increasing black soybean content. A doenjang product made using a 1:1 ratio of soybeans-black soybeans showed a maximum level of genistein and daidzein isoflavones ($1111.6{\mu}g/g$) at 110 days of fermentation, along with decreasing contents of genistin and daidzin due to the conversion to aglycones. The black soybean-only doenjang sample showed higher protease activity, including caseinolytic and fibrinolytic enzyme activities, than the other samples, and had relatively higher polyphenol content and DPPH radical scavenging activity. Therefore, doenjang made with additions of black soybeans and fermented by B. subtilis SCB may have improved physiological properties, suggesting this to be a valuable method of preparation.

  • This study evaluated the quality characteristics and antioxidant activities of cookies after adding black ginseng powder at ratios of 0%, 1%, 3%, 5%, and 7%, and the potential of black ginseng as a functional food. The moisture content increased with an increase in the black ginseng powder content while the pH decreased. The L value decreased with increase in the black ginseng powder content while the a and b values increased. The hardness decreased with increase in the black ginseng powder content. Notably, antioxidant activities, such as 2,2-diphenyl-1-picryl-hydrazyl (DPPH), 2-2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt (ABTS) radical scavenging showed the highest increases in cookies containing 7% black ginseng powder. The total phenol and flavonoid contents significantly increased according to the amount of black ginseng powder added. These results suggest that black ginseng powder can be applied to cookies to achieve high quality and antioxidant activity.

  • Control of hyperglycemia and dyslipidemia is strongly correlated with decreased risk for cardiovascular disease, the most common and fatal diabetic complication. The purpose of this study is to determine the effects of garlic and aged black garlic on glycemic control and blood lipid profile in animal model of type 2 diabetes. Three week-old db/db mice (C57BL/Ks, n=21) were fed AIN-93G semipurified diet or diet containing 5% freeze-dried garlic or aged black garlic for 7 weeks after 1 week of adaptation. Fasting serum glucose, insulin, triglyceride, total cholesterol, and HDL-cholesterol and blood glycated hemoglobin were measured. Body weight and food intake of garlic and aged black garlic group were not significantly different from those of the control group. Fasting serum glucose and blood glycated hemoglobin levels were significantly decreased and insulin level was significantly increased in garlic group compared with control group (p<0.05). Consumption of aged black garlic significantly decreased homeostasis model assessment for insulin resistance (HOMA-IR) and tended to decrease serum glucose. Garlic consumption significantly decreased total cholesterol, while aged black garlic significantly reduced serum total cholesterol and triglyceride and increased HDL-cholesterol levels. These results suggest that garlic exerts hypoglycemic and hypocholesterolemic effect and aged black garlic improved insulin sensitivity and dyslipidemia in db/db mice.

  • Hwajeon, pan-fried rice cake, containing glutinous black rice flour at different proportions (0, 5, 10, 20, 30, or 50% of glutinous rice flour) was cooked to investigate the cooking effect on anthocyanins, color, and texture. Two anthocyanins, cyanidin-3-glucoside and peonidin-3-glucoside, were detected in both hwajeon dough and pan-fried hwajeon. The hwajeon retained up to 60% of anthocyanins in the dough after pan-frying. The lightness (L) of dough and hwajeon decreased with an increase in the amount of black rice flour rice flour. Interestingly, the lightness (L) of hwajeon was significantly lower than the counterpart dough, indicating that the color of hwajeon resulted not only from anthocyanins, but also from the browning reaction occurring during pan-frying. The redness (a) of hwajeon initially increased by adding glutinous black rice flour, and decreased at higher than 10% of black rice flour. In comparison with the control hwajeon (0% black rice flour), the black rice-added hwajeon showed lower hardness, whereas it had higher springiness and cohesiveness, resulting in no significant differences in gumminess and chewiness among the hwajeon. These results indicate that hwajeon enriched with glutinous black rice flour can be developed as a functional food containing health-promoting anthocyanins.

  • Black ginseng and white ginseng were extracted with 80% ethanol and evaluated for relative ginsenoside composition, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities, and antioxidant properties. As analyzed by HPLC, black ginseng contained a greater proportion of ginsenoside $Rg_3$ compared to white ginseng. White ginseng was characterized by undetectable ginsenoside $Rg_3$ but it contained more total ginsenosides than black ginseng. Black ginseng extract exhibited higher (p<0.05) free radical-scavenging activity, as well as higher antioxidant activities than white ginseng against 2,2-diphenyl-1-picryl-hydrazyl, superoxide dismutase, and xanthine oxidase, despite the fact that the total saponin content was higher in white ginseng than black ginseng. In addition, the black ginseng extract displayed greater AChE and BChE inhibitory activities. These results suggest that black ginseng has stronger effects on anti-oxidation and AChE and BChE inhibition than white ginseng.
