  • This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP- I : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-N: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP- II had the highest total phenol contents ($28.55{\pm}1.56\;mg/l00\;g$), and AP- V the highest level of flavonoids ($47.61{\pm}1.58\;mg/l00\;g$). At $78.89{\pm}0.16%$, AP- V displayed the strongest electron donating ability followed by AP-II($57.99{\pm}0.21%$) and API ($37.66{\pm}0.20%$). Reducing power was also significantly higher in AP- V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from $114.47{\pm}2.18{\sim}121.39{\pm}4.36%$ and ALDH activity ranged from $100.04{\pm}2.90{\sim}129.54{\pm}4.80%$; AP- I , AP- II, and AP- Vin 12.5% of alcoholic concentration. The composites of AP- I , AP- II, and AP- V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-III and AP-N. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP- V was higher than its ADH activity.

  • This study investigated the effect of added freeze-dried mulberry fruit juice (FDMJ) (1, 3 and 5%) on the antioxidant activity and fermented characteristic of yogurt during refrigerated storage. A decrease in pH of yogurt and increase in acidity was observed during fermentation. The yogurts with FDMJ exhibited faster rate of pH reduction than control. Initial lactic acid bacteria count of yogurt was 6.49-6.94 Log CFU/g and increased above 9 Log CFU/g in control and 1% in FDMJ yogurt for 24 h. The total polyphenol and anthocyanin content of FDMJ yogurt was higher than that of control due to the presence of phytochemical contents in mulberry. Moreover, antioxidant activity such as DPPH and reducing power was highest 5% FDMJ yogurt. During cold storage, pH decreased or remained constant in all yogurts with values ranging from 4.08 to 4.78 units. In sensory evaluation, the score of 1% FDMJ yogurt was ranked higher when compared with other yogurts. It is proposed that mulberry fruit juice powder can be used to improve sensory evaluation and enhance functionality of yogurt.

  • In this study, we investigated maximum yield of radical scavenging activity (RSA) using each of various extraction solvents and procedure from noni friut (Morinda citrifolia). Noni fruits were either sun-dried (FS) or hot-air dried (FO) at $60^{\circ}C$ after steam blanching. For optimum aqueous extraction, noni fruits should be sun dried and autoclave extraction time should not be over 30 min to produce extraction with high RSA with low cost. In case of 50% ethanol extraction, reflux extracts of FS and FO resulted in $IC_{50}$ of 1.92 mg/mL and 3.06 mg/mL at 8 hr. When $IC_{50}$ values were lower than 5 mg/mL, coefficient of correlation was 0.71 indicating that 71% of the phenolic antioxidants in noni fruits were accounted for the activity by scavenging free DPPH. However, coefficient of correlation significantly decreased to 0.63 over $IC_{50}$ values of 5 mg/mL. Autoclave extraction contained chlorogenic acid of $14.69 \;{\mu}g/mL$ and scopoletin of $3.86 \;{\mu}g/mL$. Reflux extraction showed all three compounds, chlorogenic acid ($26.19 \;{\mu}g/mL$), quercetin ($19.59 \;{\mu}g/mL$), and scopoletin ($17.4 \;{\mu}g/mL$). Therefore, the result of this study indicated that the potential antioxidant activities and functional values were obtained significantly with reflux extraction from noni fruit.

  • In order to examine the nutritional value of prickly pear(Opuntia humifusa), contents of ash, protein, fat, minerals and vitamins were determined on freeze-dried stem, fruit, seed and root from plants harvested in autumn. The average moisture contents for stem, fruit, seed and root were 67~87%. Crude ash content determined on dry weight basis was 2~3%. Crude protein existed mostly in seed(2.95%) and root(2.37%). Crude fat was detected mainly in seed(4.49%). Contents of major minerals(mg/100 mg dry weight) was generally higher in stem. Ca in stem(4,142.30) and fruit(2,790.86) were much higher than in seed(43.37). P in stem, seed and fruit were 448.19, 263.20 and 161.59, respectively. Stem also displayed more abundant Mg(1,110.86), Zn(35.62) and Mn(37.07). However, fruit contained higher amounts of Fe(13.38) and Se(0.15). Vitamin A was negligible in all plant parts. Vitamin E contents in fruit and stem were 1.78 mg and 1.22 mg/mg dry weight, respectively. Vitamin C was detected mostly in fruit(445.40) and stem(260.94). Use of a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide-based microtiter assay of cell viability demonstrated an anti-proliferative effect of O. humifusa extract on the MCF-7 estrogen-dependent human breast cancer cell line.

  • This study used a food-frequency questionnaire to estimate fruit consumption by sex, age, and type of fruit to analyze the association between fruit type and metabolic factors. Using food-frequency-questionnaire data from 3,091 adults aged 19~64 years (1,184 men and 1,907 women) in the 2016 Korea National Health and Nutrition Examination Survey, this study analyzed weekly fruit consumption and the consumption frequency of strawberry, oriental melon, watermelon, peach, grape, apple, pear, persimmon/dried persimmon, tangerine, banana, orange, and kiwi by sex and age groups. Apple was the most-consumed fruit (459.45 g/wk), followed by pear (165.80 g/wk), watermelon (124.80 g/wk), and banana (115.32 g/wk). After adjustment for confounding factors, ED: Please give examples. in the women who ate more than the median consumption of apple, the prevalence of hyperglycemia was 27.4% (OR: 0.726, 95% CI: 0.539~0.979) (p=0.0362), and of high triglycerides, 25.7% (OR: 0.743, 95% CI: 0.564~0.978) (p=0.0340). These rates were lower than those of women who ate less than the median consumption of apple. The results of this study suggest that apple consumption helps improve metabolic indicators in Korean adults.

  • This study was observed the effects of drying methods on the extraction characteristics of Rubi fructus (fruits of Rubus coreanus). Extraction yields of soluble solids and total sugar were high in the Rubi fructus dried by freeze drying, followed by infrared drying and sun drying. Extraction yield of phenolic compounds and DPPH radical-scavenging activity of extracts were in the following order; the Rubi fructus dried by freeze drying, the Rubi fructus dried by infrared drying, the Rubi fructus dried by sun drying. L value was the highest in the Rubi fructus dried by freeze drying, and a and b value were lowest in the fruit dried by freeze drying. These results suggest that freeze drying has an beneficial effect to enhance the quality of Rubi fructus. Water and ethanol extractions was more effective in the extraction of soluble solids and the antioxidative components.
