  • Mulberry (oddi) is one of the most popular functional foods with many physiological components. This study investigated and compared the nutritional compositions and physiological activities of four mulberry fruits from Morus albo L. including Cheongilppong, Iksuppong, Suwonppong and Cheongsuppong (a new cultivar from Chungcheongbuk-do). To analyze the nutrient contents, mulberry fruits were freeze-dried. The results showed that the proximate compositions of the four mulberry cultivars ranged from 9.61~14.11% for moisture, 8.28~11.90% for crude protein, 3.70~4.86% for crude ash, 4.28~5.54% for crude lipid and 7.46~10.78% for crude fiber. The above proximate contents of mulberry cultivars were not significantly different. However, Cheongsuppong had the highest content of reducing sugar, 74.7%. Chungsuppong and Iksuppong showed higher contents of total polyphenol and anthocyanin than other mulberry cultivars, while all mulberry cultivars showed high antioxidant activities. Hypoglycemic effect had a slightly higher level in Suwonppong and Cheongsuppong than in the other samples. Taken together, the new cultivar "Cheongsu" oddi can be suggested as a potential source of functional food.

  • This study investigated change in the chemical components and antioxidant activity of ramie (Boehmeria nivea) leaves (RL) for the development of functional foods. Proximate compositions of protein, crude ash, and crude fat were 24.49, 11.41, and 4.89%, respectively. Contents of minerals of calcium (Ca), potassium (K), magnesium (Mg), and iron (Fe) were 1,874, 1,433, 362, and 16 mg/100 g, respectively. ${\alpha},\;{\beta}$, and ${\gamma}$-Tocopherol contents were 9.79, 0.18, and 1.44 mg/100 g, respectively. Linoleic and linolenic acid contents were higher than those of palmatic and stearic acid. Total phenolic and flavonoids contents showed the high level of 149 and 49 mg/g. The $IC_{50}$ values of 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl, and superoxide radical scavenging of RL extracts were 688, 424, and $596{\mu}g/mL$, respectively, while the radical scavenging values by butylated hydroxylanisole (BHA) were 92, 58, and $98{\mu}g/mL$, respectively. Thus, RL has the potential to be used as a healthy and functional food ingredient.

  • Isoflavones found in soybeans are present as glycosides and aglycones, which differ according to their chemical structure. The absorption rate and bioavailability of aglycones are greater than those of glycosides. It is known that aglycone isoflavones in soybean was converted from glycoside isoflavones by activating of endogenous β-glucosidase under drying (40~60℃) conditions after soaking. In this study, we compared and analyzed the proximate composition and isoflavone contents of soybean powders prepared under dried after soaking were analyzed. In the comparison of the proximate compositions, the moisture contents of white soybean powder dried after soaking (WSPDS) and black soybean powder dried after soaking (BSPDS) were decreased as compared with those of the control white soybean powder (CWSP) and control black soybean powder (CBSP). Whereas the contents of other proximate compositions were increased. The aglycone isoflavone contents were higher in WSPDS than in CWSP. Whereas the aglycone isoflavone contents of BSPDS had a similar content those of CBSP because of the component characteristics of black soybean. In conclusion, we believe that it is appropriate to identify and utilize the component characteristics of soybean varieties in order to induce an increase in the functional component content of soybeans under drying conditions after soaking.

  • This study investigated the nutritional compositions and physiochemical properties of three domestically cultivated jujube fruits (Boeun, Sangwhang, and Bokjo). Nutrient contents were analyzed by freeze-drying the jujube fruits. The results showed that the proximate compositions of the three jujube cultivars ranged from 7.85~13.52% for moisture, 4.65~5.24% for crude protein, 1.29~2.38% for crude ash, 0.17~1.09% for crude lipid, and 7.66~16.63% for crude fiber. The above proximate contents of jujube cultivars were significantly different. Mineral contents of Al, Fe, Mg, Ca, Na, and K in the three jujube fruits were also determined. Mn, Cu and Zn were not detected in any of the varieties. The content of Al was higher in Sangwhang, while Boeun had higher contents of Ca and K. The total polyphenol, ABTS values, and hypoglycemic effect were slightly higher in Boeun as compared to the other varieties. Taken together, Boeun could be an important source of natural antioxidant as a functional food.

  • The fiber-rich fractions including enzyme treated insoluble dietary fiber, alcohol insoluble solid, and water insoluble solid were prepared from the peel of soft ripe persimmon, and to evaluate and compare the yields, proximate compositions, monosaccharide profiles, and functional properties. The results showed that uronic acid was the main sugar followed by glucose, which indicated that all insoluble fibers were mainly composed of pectic substances and cellulose. The presence of xylose and fucose indicated the occurrence of hemicellulose. All fiber-rich fractions were exhibited high yield and functional properties. Thus, the peel of ripe persimmon could be used as fiber supplements.

  • This study compared the nutritional value of quinoa cultivated in different regions, i.e., Peru (PQ), United States (UQ), and Korea (KQ), focusing on their proximate and nutrient compositions and functional components. Moisture, protein, lipid, and ash contents were highest in KQ, and the carbohydrate content was the highest in UQ. KQ had the highest amount of total amino acids, especially lysine. KQ had the lowest levels of Na but the highest levels of K, P, Fe, Mg, Zn, and Mn. The antioxidant compounds, quercetin and kaempferol were not detected in KQ, which consequently had the lowest total phenolic and total flavonoid contents (TPC and TFC, respectively). These values were comparatively higher in UQ. Meanwhile, PQ had the highest TPC and TFC values as well as kaempferol content, but lacking quercetin. These results demonstrate that the nutritional value of quinoa varies according to the region in which it is cultivated.
