The purpose of this study was to investigate the antimicrobial activities of natural antimicrobials (10 formulas, F1~F10) against yeasts in functional beverages. The growth rates of yeasts were different with the ten different natural antimicrobial formulas tested. Yeasts grew for 14 days and the antimicrobial effect was observed between 14 and 18 days. Levels of S. cerevisiae, Z. bailii, and P. membranaefaciens were reduced to the limit of detection (ND) < 10 CFU/mL) after 28 days. Resistance against the antimicrobial effect was greatest for P. membranaefaciens, which grew to a level of 0.12~1.48 log10 CFU/mL after 14 days and was reduced to a level of 1.61~3.55 log10 CFU/mL after 28 days. The resistance of C. albicans was also high with a growth level of 0.13~1.28 log10 CFU/mL after 14 days and reduction to 1.51~5.30 log10 CFU/mL after 28 days. The antimicrobial effect of F10 was strongest for P. membranaefaciens. Every treatment reduced the microbial levels to 2.68~5.62 log10 CFU/mL after 6 months. F2, F4, F5, F6, and F10 reduced the C. albicans level to ND after 28 days while F1, F3, F8, and F9 reduced yeasts to the ND level after 6 months. The antimicrobial activities observed here will be useful for development of natural antimicrobials.

The effects of part of plum, alcohol content and addition of t-resveratrol on the formation of ethyl carbamate during the fermentation for wine were investigated at a time interval (45 days) for 6 months. The concentration of the ethyl carbamate in plum wine was determined according to KFDA guideline for ethyl carbamate analysis. In the plum wine with 16% or 30% alcohol content, the concentrations of ethyl carbamate were increased with time of fermentation periods. The maximum concentrations of ethyl carbamate in 16% and 30% plum wines after the fermentation for 6 months were 0.071 μg/g and 0.188 μg/g, respectively. When t-resveratrol was added at the level of 10 μg/g in both 16% and 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.216 μg/ g, respectively. The addition of t-resveratrol at the level of 300 μg/g in both 16% or 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.169 μg/g, respectively. The ethyl carbamate in the plum wine was not formed during fermentation for 6 month as using the flesh of plum, but 0.588 μg/g of ethyl carbamate was formed as using plum with plum seed. The addition of 300 μg/g of t-resveratrol actually increased the concentration of the ethyl carbamate by 0.088 μg/g as fermented for 6 months using plum with seed. These results suggest that the flesh of plum should be used to reduce the formation of ethylcarbamate for production of plum wine and that the addition of t-resveratrol during fermentation of plum wine can not reduce the concentration of the ethyl carbamate.

The risk ranking of food groups included the Korea Food Code is a potentially powerful means to prioritize food safety management strategies. Although the interest in risk ranking of food groups has been increasing worldwide, there was, until recently, no standard system in Korea for the risk ranking of food groups. This study was conducted to rank food groups using theoretically estimated comparative risk scores of 101 food groups included the Korea Food Code. These scores were estimated using the risk evaluation model, which focuses on 3 aspects, namely, exposure assessment, severity assessment, and consumption part. The results of this study revealed that the risk was the highest in the case of ready-to-eat (RTE) food items, followed by fish products and breads. Using this ranking system, we can identify the food with high risk scores and design risk management strategies targeted specifically at these items.

Antioxidative activities of fresh, steamed and black garlics by different processing condition were investigated on the soybean oil. The crushed fresh, steamed and black garlics were added to 100 mL of soybean oil at a level of 0, 5, 10, 20 and 40 g respectively, and then the oil mixture containing garlics (reaction samples) were heattreated for 48 hrs at 180℃ . The chromaticity of reaction samples were increased during heating. After 48 hrs heating, in the sample added 40 g/100 mL chromaticity of each samples were 1.36, 2.99 and 1.99, in the crushed fresh, steamed and black garlics, respectively. Anisidin value showed irregularly increased during heating. Acid values of reaction samples were higher than control during heating, those levels were ranged from 0.82 to 2.04 mg/g after 12 hrs, were gradually increased to 3.15~4.30 mg/g after 48 hrs. Peroxide value of reaction sample containing black garlic(40 g/100 mL) was lower than the samples containing tocopherol or BHT, after 48 hrs heating. TBA value of reaction samples containing fresh, steamed and black garlic of 40 g/100 mL were the lowest in the sample added black garlic, after 48 hrs heating. These results suggested that oxidative stability of black garlic in soybean oil was more potential than the other garlics during heating.

The study was conducted to evaluate the effect of drying, curing and freezing on the quality of beef. Three types of dried (without salt = T1, with salt = T2 and salt + spices = T3); three types of cured (salt curing = T4, sugar curing = T5 and brine curing = T6) and three types of frozen beef (0℃ = T7, -10℃ = T8 and -20℃ = T9) were analyzed at different time intervals up to the period of 180 d. Parameters studied were protein, fat, ash, color and cooking loss of beef. All the chemical constituents (protein, fat and ash) were decreased gradually up to 120 d. The decreasing trend was observed rapid after 120 d up to 180 d of preservation. Highest protein loss was found in T7 (11.1%) and the lowest protein loss was found in T6 (3.85%) in 180 d preservation and significant (p < 0.01) differences were observed among the different preservation methods. Highest fat loss was observed in T6 (7.62%) and the lowest fat loss was observed in T2 (3.18%) and the differences were also significant (p < 0.05) among different methods during the experimental period. Spices dried beef showed a brighter color than others and cured beef showed brown color and the intensity of color was reduced gradually with the increasing of storage period. T9 showed the lowest cooking loss among 3 treatments of frozen beef and the differences also significant (p < 0.01) up to 180 d. It might be stated that sugar curing (T5) and spices drying (T3) would be the useful technique of meat preservation in rural areas and freezing (T9) would be used in large scale preservation at urban areas.

The aim of this study was to determine exposure assessment of pathogenic bacteria in edible ices by using the monitoring data from the previous study. According to the results of exposure assessment of edible ices contaminated with S. aureus, the contamination level of S. aureus in raw materials was higher than other foodborne pathogens, and the contamination level of S. aureus in mixed samples increased much before sterilization. The most significant reduction in contamination level was observed in mixed samples after sterilization, thus, the contamination levels in frozen final products was less than that of raw materials. Overall, the possibility for the infection of foodborne bacteria from the intake of edible ices per person per day was ranged from minimum 5.89 × 10-7 to maximum 5.01 × 10-5. For more realistic estimates, consumption of edible ices and dose-response model must be studied further.

This study was conducted to develop a model for describing the effect of storage temperature (4, 10, 15, 20, 25, 30 and 35℃) on the growth of Escherichia coli O157 : H7 in ready-to-eat (RTE) lettuce treated with or without (control) alkaline electrolyzed water (AIEW). The growth curves were well fitted with the Gompertz equation, which was used to determine the specific growth rate (SGR) and lag time (LT) of E. coli O157 : H7 (R2 = 0.994). Results showed that the obtained SGR and LT were dependent on the storage temperature. The growth rate increased with increasing temperature from 4 to 35℃. The square root models were used to evaluate the effect of storage temperature on the growth of E. coli O157 : H7 in lettuce samples treated without or with AIEW. The coefficient of determination (R2), adjusted determination coefficient (R2 Adj), and mean square error (MSE) were employed to validate the established models. It showed that R2 and R2 Adj were close to 1 (> 0.93), and MSE calculated from models of untreated and treated lettuce were 0.031 and 0.025, respectively. The results demonstrated that the overall predictions of the growth of E. coli O157 : H7 agreed with the observed data.

Acrylamide in various food samples in Korea were monitored during the period beginning August 2006 through May 2007. A total of 471 food products that were purchased at local markets were categorized into 17 groups and analyzed for the acrylamide content by using an LC-MS/MS method. Food samples that were selected based on special consideration such as expert consultation, Korean food consumption data and food market shares were considered to be representative. There are very large variations in acrylamide levels within tested foods. Acrylamide content ranged from ND(not detected) to 4,002 μg/kg with all tested samples. Acrylamide levels are relatively high in ‘cereal’, ‘coffee’, ‘potato snacks’, ‘biscuit’, ‘chocolate’, and ‘prune juice’. Acrylamide was also detected in fruits, vegetables, Korean traditional cookies which are considered as safe for acrylamide.

Bacillus cereus is a gram-positive spore-forming bacterium and produces an emetic or diarrheal syndrome induced by an emetic toxin and an enterotoxin, respectively. In this study, the effect of different types of media, temperature, and time on the sporulation of B. cereus, and thermal resistance of B. cereus spores produced in various temperatures were evaluated. The highest levels of spores were detected when they are produced at 25℃. There were no significant differences in levels of spores produced at 25℃ among culture media and times while levels of spores produced at 43℃ were significantly reduced with the increase of time. However, thermal resistance of B. cereus spores could be affected by incubation temperature. In fact, higher D-values (12.0, 10.1, and 5.9 min for 2, 4, and 6 weeks, respectively) of spores produced at 43℃ were observed than did in samples produced at other temperatures (25 and 37℃). D-values of spores were 7.7, 8.2, and 12.0 min when they were produced at 25, 37, and 43℃ for 2 weeks, respectively. The sporulation of B. cereus at 25℃ could result in high amounts of spores however the sporulation at 43℃ for 2 weeks could be effective to produce thermal resistant spores.

Antifungal activity of seven natural antimicrobials, such as ε-polylysine, extract of Yucca shidigera, TLS (vitamin B1 derivative), BMB-FS, chitooligosaccharide, KDSP 001, and KDSP 002 were investigated for their applications in functional beverage. Five fungi including Aspergillus niger, Penicillium citrinum, Rhizopus oryzae, Fusarium moniliforme, and Mucor rouxii were applied as test fungi and mininum inhibitory concentrations (MICs) of antimicrobials were examined. TLS exhibited the strongst antifungal activity among tested antimicrobials and the growth of all fungi was inibited at 100 ppm. The antifungal activity of BMB-FS appeared different. The growth of Fusarium moniliforme was inhibited by BMB-FS at 100 ppm, but it exhibit antifungal activity on P. citrinum, and M. rouxii at 1000ppm. MICs of TLS appeared to be 60 ppm for four test fungi except A. niger (100 ppm). These results indicate the possible usage of TLS and BMB-FS as natural antimicrobials in functional beverage.

The trace element nutrient selenium discharges its well-known nutritional anti-tumor activity. Converging data from epidemiological, ecological and clinical studies have shown that selenium can decrease the risk for some types of human cancers, especially those of the prostate, lung, and colon. Mechanistic studies have indicated that selenium has many desirable attributes of chemoprevention targeting cancer cells through DNA single strand breaks, the induction of reactive oxygen species. However, there is no reports about the relationship between methylseleninic acid (MSeA), one of methylselenol metabolites and cell cycle arrest in LNCaP human prostate cancer cells. Our data showed that MSeA arrested G1/S pahse of cell cycle arrest and inhibited DNA synthesis in LNCaP cells and those cellular events by MSeA were due to the induction of p27 protein which is a well-known cyclin-dependent kinase inhibitor. Taken together, cell cycle arrest occurred by MSeA may contribute to the growth-inhibition of prostate cancer cells.

We investigated eight active natural antimicrobials for preservation of functional beverages that are usually degraded by yeasts rather than by bacteria due to a high sugar content and a low pH. Five strains of yeasts (S. cerevisiae, Z. bailii, P. membranaefaciens, C. albicans, and P. Anomala) were tested with eight natural antimicrobial agents (ε-polylysine, yucca extract, vitamin B1 derivative, scutellaria baicalensis extract, chitooligosaccharid, allyl isothiocyanate, sucrose-fatty acid ester, and oligosaccharide). The lowest minimal inhibitory concentrations (MIC) were 10 ppm for oligosaccharide and sucrose-fatty acid ester against S. cerevisiae and Z. bailii, 10 ppm for allyl isothiocynate against P. membranaefaciens and C. albican, and 10 ppm for allyl isothiocynate and oligosaccharide against P. anomala . No growth were observed for five kinds of yeasts in functional beverages containing sodium benzonate at concentration of 0.015% or higher. The resistance of S. cerevisiae, Z. bailii, and P. Anomala against natural antimicrobial agents was lower than those of P. membranaefaciens and C. albican. Allyl isothiocyanate, oligosaccharide, and sucrose- fatty acid ester showed the highest antimicrobial activities among the eight tested antimicrobials. These results can be applied to develop new natural antimicrobial agents to improve microbial quality of functional beverages.

Currently food-borne disease is being increased at outdoor food services including hotels and restaurants. Speedy and convenient practical monitoring techniques to determine hygienic conditions are needed. This study was designed to verify correlation of direct ATP (Adenosine Tri-Phosphate) examination method using ATP bioluminescence and surveillance with check-list by inspector. Hygienic status of personal hygiene (hands), kitchen utensils (knives, chopping boards, kitchen towels, cap openers, food storage containers, and blade of slice machines), facilities and equipments (refrigerator handles, worktables, and sinks) in five major hotels in Seoul were examined. The result of personal hygiene of hotels was relatively better than other inspection items (46.6 points in personal hygiene, 40.2 points in kitchen utensils, 40.3 points in facilities & equipments). In ATP inspection, kitchen utensils and facilities & equipments were relatively clean comparing with personal hands data (40.8 ± 6.77 RLU/cm²). After correlation analysis of surveillance in hygienic status points and ATP value, all results showed negative and high correlation. The surveillance data and ATP results investigating personal hygiene, kitchen utensils and facilities & equipments were highly correlated. The ATP examination method which shows real-time identification could be considered as an appropriate method to alternate current check-list dependent safety management in food services including hotels.

This study aimed to investigate the protective effect of Solanum nigum Linne total extract (SNT), Solanum nigum Linne leaf extract (SNL), Solanum nigum Linne root extract (SNR) on liver injury induced by Lipopolysaccharide(LPS) in Sprague-Dawley rats. SNT, SNL, SNR of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 20 days. on the day 1.5 ml/kg of LPS was injected. Four hours later, they were anesthetization with ether and dissected. Glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) were measured in serum and superoxide dismutase (SOD), catalase and glutathione peroxidase (GPX) were measured in liver homogenate. SNT, SNL, SNR extract inhibited GOT and GPT activities in LPSinduced rats, whereas increased SOD, Catalase and GPX activity in liver tissue of LPS-induced rats. These suggested that SNT, SNL, SNR could be used for functional beverage.
