  • The effects of black garlic (Allium sativum L.) addition on the quality characteristics of low-fat and low-salt meatballs during cold storage were investigated. Meatballs were divided into five groups: none (control), 0.1% ascorbic acid (T1), 1% black garlic (T2), 2% black garlic (T3), and 3% black garlic (T4). pH and lightness values were lower in the treatment groups than in controls by storage time. pH and lightness values were decreased with increasing addition of black garlic (p<0.05). Addition of black garlic to meatball resulted in significantly higher TBARS values than that of control and T1 at day 1 (p<0.05). However, the addition of black garlic to meatball resulted in significantly lower VBN values than that of control after storage for 14 d. On day 14 or 21, the VBN values of meatball with added black garlic were lower than those of control and decreased with increasing addition of black garlic (p<0.05). Although addition of black garlic produced low acceptance of color scores, the flavor, tenderness, and juiciness of meatball with added black garlic were similar to those of control and T1 (p>0.05). Based on the current results, addition of black garlic could be recommended for preventing protein degradation in low-salt and low-fat meatball. Further, black garlic could be useful to the pork meat product industry as a food additive.

  • HACCP is a scientific and systematic program that identifies specific hazards and gives measurements in order to control them and ensure the safety of foods. Transportation of livestock and its products is one of the vulnerable sectors regarding food safety in Korea, as meats are transported by truck in the form of a carcass or packaged meat in a box. HACCP application and its acceleration of distribution, in particular transportation, are regarded as important to providing consumers with ultimately safe livestock products. To achieve this goal, practical tools for HACCP application should be developed. Supply chain management (SCM) is a holistic and strategic approach to demand, operations, procurement, and logistics process management. SCM has been beneficially applied to several industries, notably in vehicle manufacture and the retail trade. HACCP-based real-time visibility system using wireless application (WAP) of the livestock distribution is centralized management system that enables control of temperature and HACCP management in real-time for livestock transportation. Therefore, the application of HACCP to livestock distribution (transportation, storage, and sale) can be activated. Using this system, HACCP management can be made easier, and distribution of safe livestock products can be achieved.

  • The chemical composition characteristics of jujube wine using different preparation methods including extraction in -soju (25%) and fermentation were investigated. The jujube wine was prepared by soaking in soju using- whole fruit(WJ-S1) or seed-removed fruit(WJ-S2). Fermentations of the jujube wine were started by using whole fruit(WJ-F1), seed-removed fruit(WJ-F2) or extracts of whole fruit(WJ-F3) after adding 24% sucrose. The pH of all samples decreased from a range of 4.92~5.42 at the start time to 3.66~4.97 after 100 days. The treatment WJ-F3 showed the lowest pH among all treatments. Total acid content was 0.67~1.01% at the initial stage and then changed to 0.51~0.88% after 100 days. Total sugar and reducing sugar contents were 1.20~13.8% and 0.50~4.45% at initial stage and then changed to 1.53~4.52% and 1.75~3.82% after 100 days respectively. These sugars decreased during the preparation and fermentation of the jujube wine. The amounts of free sugars including fructose, glucose, and sucrose ranged from 1.53~4.52% and treatment WJ-F3 showed the highest amount(1.95~13.64%) compared the other treatment. Glucose level were high in treatment WJ-S1 and WJ-S2, and fructose was increased in treatments WJ-F1, WJ-F2, and WJ-F3 after 60 days. Amino nitrogen content was 0.02~0.11% after 20 days and 0.07~0.14% after 40 days respectively. Solid content was 2.68~7.76% at the initial fermentation stage and changed to 4.81~9.73% after 100 days. Hunter color(L values) were 88.45~96.74 at the initial stage and then changed to 92.62~100.45 after 100 days. Preference tests a significant difference between the two types (extraction and fermentation) of jujube wine. And treatment WJ-S2 received the highest preference scores among the all treatments.

  • The physicochemical properties of rice flour roasted at various temperatures and times were analyzed, and the quality characteristics of tarakjuk made from these roasted rice flours were investigated. As roasting temperature and time increased, rice flour showed decreasing moisture, protein content, and glucose the major reducing sugar of rice flour. Total amino acid content did not show any significant changes, but the amount of free amino acids and individual amino acids, such as lysine, tryptophane, and tyrosine, decreased. A decrease in L value and increases in a and b values from both roasted rice flour and tarakjuk was observed. Reduced crystallinity and gelatinization temperatures of roasted rice flour were investigated with X-ray diffractogram and DSC, respectively. The thermal transitions between $100.6{\sim}127.6^{\circ}C$ of tarakjuk by DSC are considered to be due to the melting of amylose-lipid complex. As the roasting temperature and time of rice flours increased, tarakjuk showed lower viscosity and higher spreadability. Sensory characteristics, such as nutty flavor, color intensity, and gritty texture increased significantly. Tarakjuk made from rice flour roasted at $185^{\circ}C$ for 25min showed the highest score on overall preference. From the above results, roasted rice flour produced more preferable tarakjuk than nonroasted flour in terms of sensory quality.

  • Seungmagalgeuntang (SG) is broadly used in traditional Oriental medicine especially in Korea, China, and Japan, for its many pharmacological effects. This study was carried out to investigate the antioxidative, antimicrobial, and anticytotoxic activities of SG and fermented seungmagalgeuntang (FSG). DPPH radical scavenging activities of SG and FSG were 70% and 74%, respectively, which increased slightly by fermentation. Nitrite scavenging activities were strongly altered at pH 1.2, (36.4% in SG and 38.3% in FSG) by addition of $200{\mu}g/g$. Superoxide dismutase-like activities were from 21.5% to 23.3% at a concentration of 0.4 mg/mL, and the highest value were observed in FSG. Total flavonoid contents of SG and FSG were 47.1 and $52.1{\mu}g/L$, respectively which shows an increase upon fermentation. In the antimicrobial activity test, $MIC_{50}$ values of SG and FSG were $800{\mu}g/mL$ for Candida albicans and 3,200 and $1,600{\mu}g/mL$ for Staphylococcus epidermidis and Staphylococcus aureus, respectively. Antibacterial effects were higher in FSG compared to SG. Anticytotoxic cadmium toxicities ranged from 63.5% to 76.1% at $10{\mu}g/mL$ of SG and FSG, and the highest value was observed in FSG. In the sensory evaluation, color, flavor, and overall preference values were higher in FSG.

  • Baechu kimchi without cuttlefish (control), baechu kimchi with cuttlefish (CK), cuttlefish baechu kimchi with yogurt (CK+Y), and cuttlefish baechu kimchi with vitamin C (CK+VC) were prepared, and the fermentation characteristics of the prepared kimchi samples were investigated during 28 days of fermentation at $4^{\circ}C$. The levels of moisture, crude lipid, and crude ash did not differ much among the samples, but the crude protein levels of CK, CK+Y, and CK+VC were greater than that of the control. The pH values of CK+Y and CK+VC slowly decreased compared with those of the control and CK during fermentation. The acidity increased sharply until 21 days then gradually increased thereafter. The total microbial counts achieved maximum levels at 21 days, and the kimchi to which yogurt and vitamin C were added showed values lower than that of the control. The number of Leuconostoc sp. in CK+Y and CK+VC was higher than that in the control. In our sensory evaluations, cuttlefish kimchi with yogurt or vitamin C scored highest in terms of texture, sour taste, ripened taste, and overall acceptability.

  • This study was carried out to investigate nutritional composition and physicochemical properties of waxy(WGR) and nonwaxy(NWGR) germinated brown rice. Amylose contents of WGR(moisture content 15.45 %) and NWGR (moisture content 15.02%) were 4.9% and 17.9%. Reducing sugar of those were 4.91% and 2.28%. The free sugar contents of WGR were glucose 0.42%, sucrose 0.15%, maltose 0.27% and that of NWGR were glucose 0.59%, sucrose 0.50%, maltose 0.24%, respectively. Color value of WGR and NWGR were L=60.30, a=2.12, b=23.52 and L=59.51, a=3.15, b=23.04, respectively. Degree of gelatinization of WGR and NWGR were 7.67%, 5.21% and hardness of WGR and NWGR were 7.53 kg$\_$f//$\textrm{cm}^2$, 8.93 kg$\_$f//$\textrm{cm}^2$. Vitamin E contents of those were 271.8 $\mu\textrm{g}$/kg, 310.6 $\mu\textrm{g}$/kg and total dietary fiber contents of those were 4.21%, 3.17%. Total amino acids of brown rice, nonwaxy germinated brown rice and cooked germinated brown rice were 126.8 mg/l00 g, 90.8 mg/l00 g and 106.5 mg/l00 g, respectively. Among amylogram characteristics of WGR and NWGR, initial gelatinization temperature, peak viscosity, breakdown, setback were 42$^{\circ}C$, 498 B.U., 94 B.U., -48 B.D. and 70$^{\circ}C$, 212 B.D., 0 B.D., 123 B.D., respectively. Sensory properties of germinated brown rices were affected by color and flavor. Palatability score of WGR that intensity score of color and flavor were lower than that of NWGR showed high.

  • Hallabong peel oils grown in open field and green house were extracted by hand-pressing flavedo and collected on ice. Volatile flavor components of Hallabong peel oils were identified and compared by using gas chromatography and mass- spectrometry. Forty-four flavor components were identified in open field oil and 45 flavor components in green house oil. (E) -Limonene-1,2-epoxide and neral were identified only in Hallabong oil grown in open field, on the other hand, $\beta$-cubebene, $\beta$-elemene and decyl acetate were detected only in green house oil. Limonene was the most abundant component in both oils as more than 86$\%$ of peak weight, followed by sabinene (1.8$\~$ 3.6$\%$) and myrcene (2.4$\~ $2.6$\%$). The difference of the volatile profile between open field and green house oils were significantly characterized by identification and quantity of alcohol group. The total alcohols in open field and green house oils accounted for 1.8$\%$ and 0.8$\%$, respectively. Among alcohols, the level of linalool was relatively high in open field oil (1.2$\%$), however, it accounted for 0.5$\%$ in green house oil. Flavor properties of fresh Hallabong peel and flesh were also examined by sensory evaluation. Flavor properties of fresh Hallabong grown in open field were relatively stronger on both peel and flesh by sensory analysis. Sweetness was strong in Hallabong flesh from open field, and sourness in that from green house. The sensory evaluation of the preference in consideration of taste and aroma was significantly high in Hallabong grown in open field (p<0.01). From the present study, the stronger flayer properties and the preference of Hallabong from open field by sensory evaluation seem to be associated with the high level of linalool in its peel oil, and the composition of monoterpene hydrocarbons such as sabinene and (E) -$\beta$ -ocimene.

  • This paper, in which whose subjects were 43 cerebrovascular accident patients analysed the effects of flood habits and attitudes on the nutrient intake. In respect to energy intake, the subjects took 106% of RDA. The protein intake was on the average of 119.1 g, which was 187% of RDA. The fat intake by the subjects on the whole was 60.5 g. The fiber intake of the subjects was 9.6 g. Those who like sweets took in significantly less energy and carbohydrate and more fat than those who didn't like sweets. Those who liked salty flood took in 7890 mg of sodium while those who didn't like salty food took in 5579 mg of sodium. The former took in significantly more sodium than the latter (p < 0.05). The examination of the amount of nutrient intake in terms of meal pattern, showed that those who had two meals a day were significantly higher in the level of weight and BMI was significantly higher (p<0.05) and the level of energy, protein, calcium, iron, vitamin A, vitamin C and cholesterol was significantly higher. Those who thought they had heavy meals took significantly more energy, protein, calcium iron, vitamin A vitamin B$_1$and vitamin C than those who thought they had light meals. Rapid eaters took more nutrients than slow eaters. The multiple regression analysis has shown that the effect of the independent variables on the energy intake are in the order of eating speed, eating volume and eating frequency. They can explain 24.6% of the energy intake. As a result, the faster is eating speed, the heavier is eating volume, and the lower is eating frequency, the higher is the energy intake (p <0.01).
