The purpose of this study was to investigate the dietary habits and altered food preferences of stroke patients. One hundred and forty-six outpatients, who had experienced their first-ever stroke and were admitted to Asan Medical Center between July and December 2000, were studied. Using interviews, we assessed the altered food preferences, food consumption frequency, and other factors influencing the food preferences and food consumption frequency of the subjects. These results were analyzed with 2 t-tests, and multiple regression analysis, using the SPSS package program. Preferences for pork, red fish, coffee, bread and stews were higher in male stroke patients than in females. The frequency of consumption of beef, pork, white fish, red fish, egg, garlic, onion, coffee, instant noodles, bread, and culinary vegetables increased in the male stroke patients more than in the females. Food preferences were influenced by income, risk factors, subjective tastes and location of brain ischemic lesions. Food consumption frequency was affected by food preference, income, drugs, alcohol, marital status, sex, and dysgeusia. As a result of multiple regression analysis, the frequency of consumption of white fish, red fish, eggs, soy milk, milk, garlic, onions, coffee, noodles, bread, bean-paste stew, kimchi, culinary vegetables, and greasy foods were the most affected by each food preference. Our results suggest that food consumption frequency may vary with food preference, income, drugs, alcohol, marital status, sex, and dysgeusia, and nutrition education should be formulated to prevent stroke recurrence based on the food preferences, subjective tastes, and risk factors of individual stroke patients.

The purpose of this study was to investigate the effects of Natto supplementation on lipid metabolism in rats. Male rats were fed on casein(CON group), steamed soybean(SS group), conventional Natto(N-1 group), garlic(2%) added Natto(N-2 group), red pepper oleoresin(0.2%) added Natto(N-3 group) and galic(2%) and red pepper oleoresin(0.2%) added Natto(N-4 group) as a protein source for 4 weeks. Serum and liver cholesterol levels were significantly lower in the experimental groups than in the control group. Especially, dietary N-2, N-3 and N-4, compared with CON, reduced markedly the concentration of serum cholesterol. The concentration of serum HDL-cholesterol was higher markedly in the N-4 group than in the control group. The concentration of serum triglyceride was significantly lower in the N-1, N-2, N-3 and N-4 groups than in the control group. Garlic and red pepper added Natto fed groups(N-2, N-3, N-4) showed more excreion of fecal bile acid when compared with those values of casein fed group. The results indicate that spice added Natto supplementation may have more beneficial roles in lipid metabolism through reduced cholesterol levels and increased fecal bile acid excretion.

This study was conducted to investigate the effect of various natural ingredients for manufacturing meat products on the $D_{10}$ value and relative radiation sensitivity (RRS) of foodborne pathogens inoculated into ground beef. The pathogens used for this study were Salmonella Typhimurium (KCTC 1925), Escherichia coli (KCTC 41682), Listeria monocytoges (KCTC 3569), and Staphylococcus aureus (KCTC 11764), and the natural ingredients added into ground beef were garlic, onion, black pepper, hot pepper, ginger, green onion, carrot, and red wine. The $D_{10}$ of E. coli was decreased significantly by 5% of garlic addition (RRS=1.460), and the addition of carrot (RRS=1.086) and red wine (RRS=2.864) also showed similar results. Most natural ingredients were effective in increasing radiation sensitivity of L. monocytogens, but only garlic, onion, hot pepper, carrot, and red wine were effective against S. aureus. In particular, the addition of red wine to ground beef showed the greatest increase of radiation sensitivity for 3 pathogens tested in the present study, except for S. Typhimurium. Results indicate that the use of certain natural ingredients for manufacturing processed meat products may have effects in the increase of radiation sensitivity of pathogens. This increased radiation sensitivity can reduce the target irradiation dose for obtaining the same level of safety, resulting in lowering the adverse quality changes caused by a high-dose irradiation process.

Contents of insoluble(IDF), soluble dietary fiber (SDF), and total dietary fiber(TDF) of 30 foods which are consumed commonly by 80 Koeran male college students were determined by Prosky and colleagues' enzymatic-gravimentric method. Foods with highest intake frequency were rice, Kimch'i, and red pepper powder. TDF, IDF, and SDF contents of rice were 0.96, 0.59 and 0.37g/100g wet wt., respectively and tose of Kimch'i were 3.07, 2.19 and 0.88g/100g wet wt., respectively. Red pepper powder contained high amount of TDF(39.37) and IDF (33.13g/100g wet wt.). The TDF content of the 30 foods ranged from 0.70 to 39.37g/100g wet wt. Red pepper (39.37), dried laver(31.36), and dried sea mustard (37.77g/100g wet wt.) contained high amounts of TDF. The IDF content of the 30 foods ranged from 0.13 to 33.13g/100g wet wt. Red pepper powder (33.13), dried laver(15.55) and sesame(15.43g/100g wet wt.) contained high amounts of IDF. SDF of the 30 foods ranged from 0.01 to 25.66g/100g wet wt. Dried sea mustard(25.66), dried laver(15.81), coffee powder (13.17), and garlic(8.72g/100g wet wt.) were good sources of SDF. % ratio of SDF to TDF of the 30 foods was lower than 50% except soybean curd(94.27%), coffee powder (88.93%), garlic(86.17%), dried sea mustard(67.94%), and dried laver(50.41%). It is recommended to increase intake of seaweeds in order to supply TDF adn SDF properly.

This study was conducted to investigate the quality characteristics of red pepper paste (RPP) added with garlic during aging at $10^{\circ}C$ for 56 days. RPP was evaluated for pH, acidity, free sugar contents, Hunter's color values, flavor patterns, and sensory characteristics. The initial pH and acidity of the RPP with garlic were 5.07~5.18 and 0.33~0.35%, respectively. The pH of RPP increased as the amount of garlic added increased, whereas the acidity decreased. The pH and total acidity changed gradually until day 28, after which they changed rapidly. The initial fructose and glucose contents of the RPP with garlic decreased to 2.32~2.41% and 1.94~2.09%, respectively. The fructose and glucose contents further decreased gradually to 1.81~1.94% and 1.54~1.71%, respectively, during aging. The Hunter's L- and b-values of the RPP increased, whereas the a-value decreased as the amount of garlic added increased. The flavor patterns of the RPP with garlic noticeably differed from those of the control RPP during aging. Sensory evaluation indicated that garlic could enhance the overall flavor characteristics of RPP.

Water extracts were extracted on water bath for 3 hrs at 90${^{\circ}C}$ after 5 times water was added to hot-air dried garlic (DG) and red ginseng (RG), respectively. Its extracts were dried on rotary evaporator, and then the mixture samples were prepared from RG extracts added to DG extracts at 5, 10, and 15%. To test biological activities such as DPPH, nitrite scavenging, tyrosinase, $\alpha$-glucosidase, human gastric (AGS), and human colon cancer cell (HT-29) growth, dryness of DG, RG, and mixture samples were diluted 500-10,000 $\mu$g/mL adding deionized water, respectively. DPPH scavenging activities of mixture sample were slightly higher than DG and RG sample alone. Nitrite scavenging activity was the highest in DG, and the other samples were below 45%. Inhibition activity of tyrosinase was below 35.0% in tested all samples. Inhibition activity of $\alpha$-glucosidase was lower in DG or RG alone, while its activity of mixture sample was increased in proportion to concentration of RG extracts. Inhibition of AGS cell growth was more effective in mixture samples than DG and RG alone, while inhibition of HT-29 cell growth was more effective in DG or RG alone than mixture samples.

This study was carried out to investigate the effects of various subsidiary ingredients added to Kimchi on the acceptance and sensory characteristics. In appearance acceptance, Kimchi without red pepper powder rated the worst, while samples without salt-fermented anchovy extracts, garlic, ginger, radish, green onion and onion showed no significant difference(p<0.05) compared with the control, and were all rated highly in acceptance. In flavor, taste and overall acceptance, the sample without garlic rated the worst, indicating that garlic has the greatest effect on the acceptance of Kimchi. Red pepper powder had an effect only on the pungency of Kimchi's flavor characteristics. Salt-fermented anchovy extracts enhanced umami taste, sweetness and saltiness of Kimchi. Garlic also enhanced the general flavor such as sourness, umami taste, sweetness, carbonated flavor and fresh flavor, but inhibited the moldy flavor. Ginger had effects on pungency, fresh flavor of Kimchi, while radish, green onion and onion only had an effect on the fresh flavor of Kimchi. Garlic had significant effects on the moldy flavor and bitterness of Kimchi's sensory characteristics, and the amount of garlic added to Kimchi influenced the sourness, sweetness and fresh flavor, irrespective of the kinds of Kimchi and fermentation temperature.

This study focuses on the qualitative characteristics of mackerel marinated with herb extracts. By differentiating the amounts of garlic, ginger and basil, the optimal amount of each ingredient to he added has been found. According to the result of the experiment, the highest level of preference has been shown for the combination of 3% of garlic, 3% of ginger and 2% of basil, generating the optimal amounts to be added. Since the pH change shown by the mackerel marinated by adding the optimal combination of 3% of garlic, 3% of ginger and 2% of basil is included in the range of pH 6.2-6.4, which is the initial point of decomposition for red-fleshed fish, it can be considered to be appropriate for the qualitative characteristics of the product. According to the differences test, GA3 bas shown the lowest level of strength, making it soft. Also, GA3 has shown the highest level of elasticity together with the characteristic of being moist. As a result, it can be said that garlic is better than ginger and basil. According to the preference test, GA3 has shown the highest level of preference in terms of appearance, flavor, texture, taste and overall preference. By considering the above results of the experiment, GA3 (3% of garlic) can be regarded as the optimal amount to be added.

The mixture of botanical antimicrobial agent-citurs product and ginseng extract mixture(BAACG) was applied to garlic stalk or pork cooked in soysauce to extend their selflife. BAACG showed a remarkable antimicrobial activity against a wide spectrum of food-borne infection microorganisms and thermal and pH stability. In comparison with scanning electron microscopic photos of microbial cells not-treated and treated with BAACG the physiological cytomembrane function of BAACG-treated microorganisms was destroyed and the dead cell numbers was increased. The quality of garlic stalk or pork cooked in soysauce was controlled by the addition of BAACG in their raw materials. BAACG-treated garlic stalk or pork cookeries showed considerably to decrease the numbers of total cell count and expressed no odor and no sticky state appeared in the control. BAACG was expected to be a preservative agent which could be applied to raw or processed food stuffs in the view of food safety.
