  • This study investigated the optimal mix ratio of frozen-dried loquat fruit powder and the optimun conditions for making Seolgidduk by analyzing chemical properties, rating moisture contents, color, mechanical quality characteristics and sensory characteristics Seolgidduk was made with 0, 2, 4, 6 and 8% frozen-dried loquat fruit powder, which contains functional components. Chemical analysis showed that loquat fruit powder contained of 12.87% water, 2.23% crude protein, 0.55% crude fat, 3.57% crude ash and 3.89% crude fiber. Water content of Seolgidduk containing loquat fruit ranged from 36.58~39.18%. With more loquat fruit powder L value decreased, while the 'a' value and 'b' values increased. According to scanning electronic microscopy, Seolgidduk containing frozen-dried loquat fruit powder showed weak coherence. Hardness decreased with more frozen-dried loquat fruit powder. In the sensory test, Seolgidduk with 4% loquat fruit powder was the most preferred with less sourness, proper softness, moisture and chewiness. Based on the results of this experiment, Seolgidduk with 4% loquat fruit powder showed less hardness than the control group. These results show that quality and preference increased when 4% loquat fruit powder was added to Seolgidduk. Therefore, Seolgidduk with 4% of loquat fruit powder is expected to increase quality and preference of Seolgidduk.

  • In recent years, the home meal replacement (HMR) market has expanded and the consumption of ready-to-heat (RTH) rice has significantly increased. In this study, RTH rice products containing seaweed were prepared with different types of grain: white rice, a mixture of white rice and barley, barley, and mixed grains. The control was a commercial RTH white rice without seaweed. The proximate components, total dietary fiber, in vitro starch digestibility, and antioxidant activity were compared. The ash content of the RTH seaweed rice was higher than that of the control (P<0.05). The total dietary fiber of the RTH seaweed rice was in the range of 1.03-6.57%, which directly impacted the in vitro starch digestibility. The in vitro antioxidant activity including total phenolic content, reducing power, DPPH (2,2-diphenyl-1-picryl-hydrazyl) and ABTS+ (2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) radical scavenging activity of the seaweed rice with barley and the white rice/barley mixture was greater than that of the other rice products (P<0.05). These results indicate that the in vitro digestibility and antioxidant activity of the HMR RTH seaweed rice were greater than those of the control. In addition, when the RTH seaweed rice was prepared with barley, the functional activity improved.

  • The purpose of this study is to determine the possibility of using Flos Sophora japonica as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Flos Sophora japonica a were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 67.76%, 19.87%, 4.61% and 7.76%. And the calories of Flos Sophora japonica Linne was 318.32 Kcal. Total dietary fiber was 25.35% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 1.80 % and 23.56 %, respectively. The protein were contained total 18 different kinds of amino acids. The contents of non-essential and essential amino acids were 4,898.78mg and 5,953.51mg. The K was the largest mineral followed by Ca, P and Mg, which means Flos Sophora japonica Linne is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 29.69%, 34.93% and 35.38%. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of vitamin C in Flos Sophora japonica Linne was higher than that of any other plant, which suggest that it could increase blood elasticity. The content of rutin, which is responsible for capillary vessel permeability, was 22.60%. The contents of water soluble antioxidative materials in 1 mL of water-extracted Flos Sophora japonica Linne were 3.9 ${\mu}$g which is comparable to 1233.0 mmol of vitamin C in antioxidant effect. The general nutrients and other antioxidatant bioactive materials in Flos Sophora japonica Linne were also potential materials for good health food. It is expected that follow up study of Flos Sophora japonica Linne through developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.

  • This study was performed to investigate the influences of resistant starch (HM: HI-MAIZE) and HM-D (HI-MAIZE DIET) fortified with D-factor (consisted of Psyliium husk, polydextrose and hydrocitric acid) on the glucose and bile acid absorption and production of short chain fatty acids (SCFA). HM-D absorbed more glucose and bile acid than did HM. The glucose transport of HM and HM-D against dialysis membrane showed 77% and 68% for 4h, respectively. After 24h, bile acid transport of HM and HM -D showed 65% and 62.3%, respectively. The HM and HM-D produced 217.8 mM and 264.0mM of SCFA, respectively. The production of butyric acid in HM-D (32.7mM) showed higher than that of HM (26.9mM). The addition of D-factor to HM increased the physiological function of dietary fiber through the glucose and bile acid absorption and production of SCFA.

  • Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.

  • The aim of this study was to investigate changes in 7 nutritional components (fatty acid, protein, fat, ash, total dietary fiber (TDF), $\gamma$-aminobutyric acid (GABA), and $\gamma$-oryzanol) of paddy rice (PR) and brown rice (BR) throughout the germination process, as measured at different shoot lengths (10 mm, 20 mm, and 30 mm). With the increase of shoot length, the nutritional components' concentrations increased, as compared to the concentrations measured before germination. Moreover, BR exhibited higher GABA, $\gamma$-oryzanol, and protein than PR. Among the components, TDF, GABA, and $\gamma$-oryzanol showed significant concentration differences throughout germination, while the others exhibited only slight variations. In particular, GABA and $\gamma$-oryzanol were predominantly increased in grains of 10 mm shoot length. These compounds might prove to be important factors from germinated rice. Additionally, the germinated cultivar 'Keunnun' might also prove to be a very important food source, owing to its high GABA and $\gamma$-oryzanol contents. These results suggest that variations in nutritional components related to the increase of shoot length may prove to be important when considering the beneficial aspects of rice on human health.

  • In this study, changes in the physicochemical properties and functional components of uncooked foods, including carrots, cabbage, shiitake (Lentinus edodes) and white button (Agaricus bisporus) mushrooms, sea mustard, and laver treated with electrolyzed water were investigated. No changes were observed in the primary compositions of any of the materials that were hot air- or freeze-dried after being treated with electrolyzed water. The lightness (L), redness (a), and yellowness (b) values of the carrots, shiitake, and laver were not affected by drying, while changes did occur in the cabbage (L-, a-, and b-values), mushrooms (a-value), and sea mustard (b-value) specimens that were hot air- or freeze-dried following the treatments with electrolyzed water. The dietary fiber contents of all the materials increased when they were hot air-dried. Vitamin C content decreased when the samples were treated with alkalic electrolyzed water. No changes occurred in the lectin, $\beta$-carotene, or total phenolic compound contents after the electrolyzed water treatments, suggesting that electrolyzed water could be used effectively as a pasteurization step for uncooked carrots, cabbage, shiitake and white button mushrooms, sea mustard, and laver.

  • This study was designed to elucidate the effects of mugwort powder supplemented to high fat diets on blood components levels in rats. The levels of mugwort content in the experimental diets were divided into 12, 21, 28% and the fat levels in high fat diet was 30% of total caloie intake. Forty-nine male Sprague-Dawley rats weighing 72.5$\pm$0.3g were divided into group I(add mugwort during 8 weeks), group II(add during 4 weeks) andcontrol group. The results of this study were summarized as follows : 1. There were no difference in body weight gain and FER throughout eight weeks of experiment. The organ weights were somewhat higher in control group, but not significant. 2. The mugwort groups(I, II) were significantly higher than control group in RBC. This result showed that the mugwort affect the content of RBC. Author would like to conclude this result that the RBC content of experim-ental animal was affected by the iron in the mugwort. There were no difference among experimental groups in Hb, Hct. 3. It was noteworty that the concentration of serum glucose and triglyceride in the mugwort groups(I, II) was significantly lower than the control group. This result concluded that concentration of serum glucose and triglyceride which had become high by high fat diet were affected by the calcium or dietary fiber in the mugwort. There were no difference among experimental groups in albumin, total cho-lesterol, HDL-cholesterol.
