  • The purpose of this study is to develop fresh pasta added with mulberry leaf powder as functional fresh pasta. Through previous research, the mixture of 40% of flour and 60% of rice powder was optimum for making noodles with mulberry leaf powder. Making fresh pasta with 40% of wheat flour, 60% of rice powder (optimum moo for making noodles) and mulberry leaf powder(0.5% 1.0% 1.5% 2.0%) was done, followed by the mechanical test(moisture content, color value, texture, tension) and the sensory analysis(quantitative descriptive analysis, preference test). Moisture contents of raw pasta and cooked pasta were the highest in control; scores for moisture contents of cooked pasta were higher than those of raw pasta. The result indicated that the more mulberry leaf powder was, the lower L-value and a-value were in raw pasta and cooked pasta. While the b-vale(yellowness) of raw pasta was the highest in control(9.81), 1.0% of mulberry powder addition sample was the highest in cooked pasta. For hardness, the 2.0% of mulberry leaf powder addition sample has high scores, and adhesiveness and chewiness were no significant difference. The 0.5% of mulberry leaf powder addition sample was the longest in tension distance, which was resulted from the lack of water contents in mulberry leaf powder. In cooked pasta, tension distance had no significant difference between the samples, and force showed the highest score in control. The quantitative descriptive analysis showed that color intensity, savory taste, bitterness were the highest in the 2.0% of mulberry leaf powder addition sample. Gloss and chewiness were no significant difference between the samples. Grassy flavor, savory flavor, bitterness and grainess were intense as mulberry leaf powder was added The preference test showed that MRP 1.5 containing 1.5% of mulberry leaf powder was the most preferable for color, texture and overall quality. In conclusion, 40% of wheat flour, 60% of rice powder and 1.5% of mulberry leaf powder made the best formula of fresh pasta with mulberry leaves.

  • Purpose: The purpose of this study was to evaluate dietary habits, food intakes, nutrient intakes, and diet quality of non-alcoholic fatty liver disease in a health screening and promotion center. Methods: The total number of study subjects was 10,111 adults, where 3087 subjects (30.5%) were diagnosed as NAFLD. The dietary intakes were obtained using a food frequency questionnaire. They were then compared with the dietary reference intakes could be used in the future for development of diet and nutrition guidelines s (KDRIs). Results: Mean age of subjects in the normal group was $52.9{\pm}10.3yrs$ and body mass index (BMI) was $22.4{\pm}2.6kg/m^2$, and those of the NAFLD group were $55.1{\pm}9.2yrs$ and $25.4{\pm}2.9kg/m^2$. BMI, blood pressure of the NAFLD group were significantly higher than those of the normal group. The rates of skipping breakfast, overeating, and eating out were significantly could be used in the future for development of diet and nutrition guidelines er in the NAFLD group (p < 0.05, p < 0.000, p < 0.000 respectively). The speed of eating was fast in the NAFLD group (p < 0.000). The NAFLD group consumed significantly higher amounts of grains, meats, fish, seaweeds, kimchies, sugars, sweets, coffee, teas, and oils compared to the normal group (p < 0.05). Meanwhile, intakes of starch products, fruits, milk, and milk products were significantly lower in the NAFLD group compared with those of the normal group (p < 0.05). Riboflavin, calcium, and dietary fiber nutrient adequacy ratio (NAR) of the NAFLD group were significantly lower than those of the normal group. The Korean's dietary diversity score (KDDS) of the NAFLD group was lower than that of the normal group. Conclusion: In conclusion, we suggest that diet guidelines, such as increasing the intake of calcium and dietary fiber, reducing the intake of energy, fat, and simple carbohydrates, are necessary to improvement of NAFLD. The results could be used in the future for development of diet and nutrition guidelines for NAFLD.

  • This study investigated the effects of the oxygen permeability of vacuum packaging film and the storage temperature on the quality and shelf life of Hamburg steaks during storage for 14 days. Control samples (C) were packaged in a polyamide/polyethylene (PA/PE) film and stored at $5^{\circ}C$. Treatment samples were either packaged in an ethylene vinyl alcohol/polyethylene (EVOH/PE) copolymer film and stored at $5^{\circ}C$ (T1), and in a PA/PE film and stored at $-18^{\circ}C$ (T2). The initial total plate count (TPC) was 3.6 log cfu/g. In T1 samples, TPC and Brochothrix thermosphacta counts were increased, similar to those in C samples, whereas Pseudomonas spp. counts were significantly lower than those in C samples during storage. Over the storage period, the volatile basic nitrogen values increased most rapidly in C samples, followed by T1 and then T2 samples. The values of thiobarbituric acid reactive substances steadily increased in all samples during storage. The colour parameters were not significantly different among the samples during storage. T1 samples maintained sensory qualities in flavour and off-odour parameters for two days longer than C samples did. At day 12, T2 samples were evaluated as being below the marketability score of 5.0 for texture. In conclusion, using high oxygen barrier films like EVOH/PE copolymer for packaging Hamburg steaks could extend the sensory qualities in view of flavour and off-odour during chilled storage. However, frozen storage at $-18^{\circ}C$ is recommended when the storage period is extended beyond 14 days at $5^{\circ}C$.

  • This study was carried out to evaluate the quality characteristics of the vacuum packed pre-aged venison with seasoning during chilled storage. The ham of deer were cut to cube and two seasonings such as red pepper sauce (T1) or soy sauce (T2) were seasoned by the proportions or meat to seasonings (1:1), respectively. The seasoned venison was aging by fill into plastic box at $0\pm1^{\circ}C$ for 10 days. And then, the aged meat from each pack was vacuum-packaged and stored at $0\pm1^{\circ}C$ for up to 28 days. pH were significantly decreased with storage periods in all treatments (p<0.05). Salinity $(\%)$ were no significant differences in T1 during the whole storage, but T2 had significantly high content $(1.33\%)$ at the storage days of 28 (p<0.05). Saccarinity $(\%)$ of T1 were significantly higher than that of T2 during the whole storage periods (p<0.05). As storage time extended the value of $L^*$ and $b^*$ in T1 were increased and those values decreased in T2. $a^*$ and shear force $(g/cm^2)$ or T1 and T2 were increased as the storage period passed In the result of sensory evaluation. all treatment had relatively high score $(T1\;6.75\~T2\;7.00)$ in overall acceptability during the storage period of 28 days. In conclusion, this study suggest that vacuum packed pre-aged venison with seasoning may be useful for new deer meat menu.

  • TMR (total mixed ration) feed was developed by adding mugwort and was fed to Korean black cattle. The effects on the physicochemical properties of the Korean black cattle, when fed mugwort, were investigated, as was the feasibility of producing beef with high quality and functionality. Korean black cattle were reared by using basal TMR (control) and basal TMR supplemented with mugwort of middle fattening 4.6% and late fattening 6.5% (treatment). The content of total catechin in Korean black cattle fed with the control and treatment was 0.262 and 0.379 mg/kg, respectively, while the content of epicatechin was 0.042 and 0.059 mg/kg, respectively, both of which were a significant increase from feeding the cattle TMR with mugwort ($p$ <0.05). There was no significant difference between the control and treatment in terms of $L^*$ (lightness), $b^*$ (yellowness), pH, VBN (volatile basic nitrogen) content, bacterial counts, water-holding capacity, freezing loss, thawing loss, cooking loss, cohesiveness, chewiness, shear force, and sensory score. TBARS (2-thiobarbituric acid reactive substances) and springiness for the control were significantly higher than the treatment ($p$ <0.05). The $a^*$ (redness), EDA (electron donating ability), hardness, and gumminess for the treatment were significantly higher than for the control ($p$ <0.05). These results suggest that the feed containing mugwort can be used to improve color and increase antioxidant ability as functional feed.

  • Several commercial soybean oils were stored at $20^{\circ}C,\;40^{\circ}C$ and $60^{\circ}C$ with daily exposure of fluorescent light for 12 hours and evaluated their rancidity by headspace gas chromatographic analysis of pentanal and hexanal. The data of gas chromatographic analysis was compared with organoleptic flavor evaluation. For headspace gas chromatographic analysis, the volatile compounds were recovered by porous polymer trap and flushed into a fused silica capillary column at $250^{\circ}C$, The pentanal and hexanal separated were identified by gas chromatography and gas chromatography-mass spectrometric method. The results showed that the contents of pentanal and hexanal were linearly increased during storage for 100 days. A very simple linear relationship was found between organoleptic flavor scores and amounts of two volatile compounds with very high correlation coefficient. A similar linear relationship was also obtained for acid and peroxide value with sensory data. This results suggested the possible implication of pentanal and hexanal as an quality index for rancidity evaluation of soybean oil.

  • The purpose of the study was to develop an eating habit checklist for screening elementary school children at high risk of energy overintake. Dietary habits, food intake, anthropometric data were collected from 142 children (80 boys and 62 girls) in the 4th to 6th grades of elementary schools. Energy intake, fat intake, and percentage of Estimated Energy Requirement (%EER) were used as indices to detect the risk of energy overintake of the children. Pearson correlation coefficients were calculated between dietary habit scores and energy overintake indices in order to select questions included in the checklist. TV watching during the meal, meal speed, meal amount, overintake frequency, eatingout frequency, snack frequency, frequency of eating Ramyun or fast foods showed significant correlations with energy overintake indices. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 7-item checklist with test results from 0 to 13 points was developed, and those with equal or higher than 5 points were diagnosed as a risk group of energy overintake. Among our subjects 13.4% was diagnosed as the risk group. Mean energy intake of the subjects in the risk group and the normal group were 2,650 kcal and 1,640 kcal, respectively. However, there were no significant differences of Index of Nutritional Quality (INQ) of the other nutrients except eating fiber between the risk group and the normal group. This checklist will provide a useful screening tool to identify children at high risk of energy overintake.

  • This study was conducted to evaluate the physicochemical properties of pork loin marinated with a solution of Nan and sodium tripolyphosphate, and the sensory attributes of tomato sauce-stewed products using marinated loin. Pork loin samples were cut $(3{\times}3{\times}2cm)$ and assigned to 3 treatment groups [C; unmarinated control (100% distilled water), T1; 10% sodium chloride, T2; 10% sodium chloride + 3% sodium tripolyphosphate]. Samples were marinated for 24hr at $5^{\circ}C$. The uptake of marinade in the treatment groups was significantly greater (p<0.05) than that of C, however no significant difference between the two treatments was observed. Cooking losses were highest (p<0.05) for T1, while lowest (p<0.05) for T2. All marinated loins had a significantly higher (p<0.05) yield than the control. The pH of the marinade solution ranged from 7.00 for T1 to 8.47 for T2. The two marinated loins had a significantly higher (p<0.05) $pH_{24}$ than the control. The water holding capacity (WHC) was highest for T2, and lowest for T1. CIE $L^*,\;a^*,\;b^*$ tended to be slightly higher in the control than either treatment group. The shear force value $(kg/cm^2)$ of yaw meat did not differ between the control and marinated muscle samples. However, cooked meat had a significantly lower (p<0.05) shear force value in T2 than C and T1. Hardness values were significantly lower (p<0.05) for both treatments compared with the control. There were no differences in texture profile, except hardness, between the control and the two treatments. Regarding the sensory evaluation of tomato sauce-stewed products manufactured with marinated pork loin, the treatment groups scored marginally well in tenderness, juiciness and overall acceptability, while the flavor score of the control was significantly higher than those of T1 and T2.
