Resveratrol was incorporated into various combinations of single- and double-layer nanoemulsions, prepared by selfassembly emulsification and complex coacervation with chitosan, alginate, and β-cyclodextrin, respectively. Resveratrol nanoemulsions were composed of medium-chain trigacylglycerols (MCTs), Tween ® 80, water, chitosan, alginate, and β-cyclodextrin. The corresponding mixtures were formulated for the purpose of being used as a nutraceutical delivery system. Resveratrol nanoemulsions were obtained with particle sizes of 10-800 nm, with the size variation dependent on the emulsification parameters including the ratio of aqueous phase and surfactant ratio. Resveratrol nanoemulsions were characterized by evaluating particle size, zeta-potential value, stability, and release rate. There were no significant changes in particle size and zeta-potential value of resveratrol nanoemulsions during storage for 28 days at 25°C. The stability of resveratrol in the double-layer nanoemulsions complexed with chitosan or β-cyclodextrin was higher, compared with the single-layer nanoemulsions.

Proximate analysis and antioxidant activity of cultivated wild Panax ginseng (CWPG) were investigated to provide fundamental information of CWPG with different ages and to increase its industrial application. Proximate analyses of CWPG with different ages were performed. Extraction of CWPG with different ages was carried out using heatreflux extraction, and their extraction yield, crude saponin content, ginsenoside content, and antioxidant activity were analyzed. Moisture content decreased, but crude fat and crude protein were increased with aging. Extraction yield and crude saponin contents did not show a specific pattern while 5-year-old CWPG revealed the highest extraction yield and crude saponin content. All CWPGs showed typical ginsenoside profiles containing C-K and Rh2 ginsenosides, which are not found in ginseng. The 3-year-old CWPG showed the highest antioxidant activity including total phenolic content, total flavonoid content, and DPPH and ABTS radical scavenging activities. Moreover, 3-year-old CWPG also revealed the highest acidic polysaccharide content. Therefore, these results suggested that 3-year-old CWPG, which is the cheapest, can be used in industrial application due to its high antioxidant activity and acidic polysaccharide content with similar ginsenoside profile compared to 5- and 7-year-old CWPGs.

It is well-known that cultivated wild Panax ginseng has anti-inflammatory effect. However, a comparative study on cultivation period vs biofunctionality is currently lacking. In this study, 70% ethanol extracts of 3-years (yrs)-, 5-yrs-, or 7-yrs-old cultivated wild ginseng were evaluated for their inhibitory effects on RAW264.7 murine macrophages. Specifically, the production of pro-inflammatory cytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-α]), the expression of surface proteins (CD80, CD86, and MHC-II), and the phagocytic properties were investigated. RAW264.7 cells were induced by 500 ng/mL of lipopolysaccharide (LPS) and treated with 0.1, 1, and 10 ppm of samples. LPS-induced IL-6, TNF-α and surface proteins in all samples were downregulated in a dose-dependent manner. Both IL-6 and TNF-α were significantly reduced at 10 ppm of the 7-yrsold sample compared to 10 ppm of 3-yrs- and 5-yrs-old samples. CD80 and CD86 were also reduced at 10 ppm of all samples, and there was no difference among samples. The phagocytosis has no difference except in 10 ppm of 3 yr-old sample. The results suggest that cultivated wild ginseng extract has anti-inflammatory effect without decreasing phagocytosis.

There have been great efforts to develop a rapid and sensitive detection method to monitor the presence of pathogenic bacteria in food. While a number of methods have been reported for bacterial detection with a detection limit to a single digit, most of them are suitable only for the bacteria in pure culture or buffered solution. On the other hand, foods are composed of highly complicated matrices containing carbohydrate, fat, protein, fibers, and many other components whose composition varies from one food to the other. Furthermore, many components in food interfere with the downstream detection process, which significantly affect the sensitivity and selectivity of the detection. Therefore, isolating and concentrating the target pathogenic bacteria from food matrices are of importance to enhance the detection power of the system. The present review provides an introduction to the representative sample preparation strategies to isolate target pathogenic bacteria from food sample. We further describe the nucleic acidbased detection methods, such as PCR, real-time PCR, NASBA, RCA, LCR, and LAMP. Nucleic acid-based methods are by far the most sensitive and effective for the detection of a low number of target pathogens whose performance is greatly improved by combining with the sample preparation methods.

농산물 가공은 농산물을 원물로 판매할 때보다 부가가치를 제고할 수 있는 방안의 하나로, 품질이 상 대적으로 낮거나 상품성이 없는 농산물을 가공을 통해 농가소득을 높일 수 있는 중요한 정책 수단의 하 나로 인식되어 왔다. 정부도 농산물 가공의 중요성을 인식하고 농산물 가공을 적극 장려하고 있다. 하 지만 식품의 가공은 농산물과는 달리 다양한 법적·제도적 규제를 받는다. 이런 법적·제도적 규제를 정확히 알지 못하고 농산물 가공을 시작할 경우 의도치 않게 법을 위반할 수도 있다. 따라서 이 논문에 서는 농산물 가공과 관련된 중요한 법규를 중심으로 농산물 가공을 위해 준수해야 할 법규의 내용을 검 토한다.

The consumption of high-salt foods is an independent risk factor for increased hypertension. Thus, evaluating the relationship of taste sensitivity and pleasantness of high-salt foods such as Korean jang products, would help contribute to an understanding of salty food eating behaviors of the Korean rural elderly. This study aimed to verify the association between taste sensitivity and salinity of Korean jang products, and the preferences of food groups and nutrient intake in the rural elderly. We studied 269 elderly persons (males 83, females 186) aged above 65 years, residing in the rural area, Sunchang gun Jeonbuk. For each subject, a recognition threshold of 4 basic tastes and pleasant concentrations of NaCl were estimated using the sip- and–spit method. Taste preferences, frequency of intake of food groups, nutrient intakes, and salinity and sweetness of Korean jang products (Doenjang, Ganjang, Gochujang) were assessed. No association was found between salt taste recognition threshold and optimally preferred concentration of salt and salinity of Korean jang products. However, the sweet taste recognition threshold was positively related to the sweetness of Korean jang products. Also, the salinity of Doenjang positively correlated with the frequencies of food groups and nutrient intakes. That is to say that the sweet taste sensitivity was related to the sweetness of Korean jang products, but was not sensitive to the salty taste. The salinity of Doenjang correlated with the consumption of food and nutrient intakes. Taken together, these findings suggest the need for appropriate intervention and education to reduce the salinity of Doenjang, which is an important modifiable factor contributing to reducing sodium intake in the rural elderly.

Stress has been associated with poor eating behavior and diet quality. Yet, the relationship between nutrient and food intake and perceived stress in Korean female adults has not been validated. The purpose of this study is to identify the relationship between nutrient and food intake and perceived stress in Korean female adults. This is a cross-sectional study based on the 2014-2015 Korean National Health and Nutritional Examination Survey data. This study investigated 2,010 female adults age 19~64. In this study, according to subjects' perceived stress, we classified subjects into very low-stress recognition group (VLSRG) (n=211), low-stress recognition group (VSRG) (n=1,223), high-stress recognition group (HSRG) (n=488) and very high-stress recognition group (VHSRG) (n=88). Daily nutrients and food group intake, food groups consumed (Dietary Diversity Score, DDS) were analyzed using data from the 24-recall method. The VHSRG had a larger proportion of subjects that were younger (p<0.0001), single (p<0.0001) and smokers (p<0.0001) compared to the VLSRG. Energy and food intake did not differ between the four groups. Percentage of subjects with protein (p=0.0322), vitamin A (p=0.0364) and vitamin C (p=0.0115) intake lower than the EAR (estimated average requirement) in the VHSRG were significantly lowest in the four groups. Also, food intake percentage from fruits and seaweed groups in the VHSRG were lower than other groups (p=0.0034, p=0.0015). DDS in the VHSRG (3.87) was significantly lowest in the four groups (p=0.0022). Results suggest that perceived stress in Korean female adults may by significant to consider in nutritional education programs.

식품용 금속 캔의 내면 코팅에 사용되는 에폭시 수지로 부터 용출되어 식품으로 이행될 수 있는 BPA, phenol, ptert- butylphenol과 BADGE, BFDGE 및 그 가수분해산물과 염화물 등 총 9종의 비스페놀 관련물질들을 HPLC/FLD 를 사용하여 동시 분석하는 방법을 확립하여 검량선 및 회 수율을 검토하고 식품유사용매로의 이행량을 조사하였다. 23종류의 식품용 금속 캔 총 161건을 대상으로 60oC에서 30분간 용출한 결과물, 4% 초산, 50% 에탄올 및 n-heptane 에서 전부 불검출이었다. 95oC에서 30분간 용출한 결과는 식품유사용매로 4% 초산과 50% 에탄올을 사용한 경우 BPA는 불검출~10.77 μg/L, phenol은 불검출~2.35 μg/L 검출되어 정량한계 수준이었으며, 국내 용출규격인 600 μg/ L에 비해 매우 낮은 수준임을 확인하였다. 또한 금속 캔은 저장성이 우수하여 식품을 장기간 보관하는 특징이 있어 보관기간(0~90일) 및 온도조건(4, 25, 60oC)에 따른 BPA 등 9개의 BPA 관련물질들의 이행량의 변화를 측정하였다. 온도조건이 4oC 및 25oC인 경우 90일 동안 모든 식품유 사용매에서 BPA를 비롯하여 9종의 BPA 관련물질들은 검 출되지 않았다. 식품유사용매로 물과 4% 초산을 사용하여 60oC의 온도에서 90일간 저장한 경우 BPA와 BADGE·2H2O 는 시간이 지남에 따라 약하게 증가하는 경향을 보였으나, 이행량이 70일 이후부터 급격한 증가 없이 대체로 유지되는 수준이었고, 검출값 또한 정량한계 수준으로 매우 낮 게 나타났다. 따라서 식품용 금속 캔으로부터 BPA를 비롯한 관련 물질들의 이행량은 안전한 수준으로 관리되고 있음을 알 수 있었다.

본 연구는 국내 미지정 피막제인 산화형 폴리에틸렌 왁스를 분석하기 위해 다양한 분석방법을 비교, 검토하였으 며, 확립된 최적 분석법을 이용하여 시중 유통되는 과일 및 견과류에서 산화형 폴리에틸렌 왁스의 사용여부를 모니터링 하였다. 최적 분석법을 확립하기 위하여 산가, HT-GPC, MALDI-TOF/MS, GC-FID, FT-IR 등을 비교하였다. 산가 측정 결과 산화형 폴리에틸렌 왁스를 첨가한 시료와 첨가 하지 않은 시료 모두 산가가 1.12 mg KOH/g로 산가의 변화가 나타나지 않아 산가를 이용한 식품 중 산화형 폴리에틸렌 왁스의 분석은 어려울 것으로 판단되었으며, HTGPC분석은 표준물질의 분산도 값이 약 3.4로 확인되었으 며, GPC를 이용한 분석은 실험실간 낮은 재현성과 컬럼 등 분석조건에 따른 결과 값이 달라질 수 있기 때문에 분자량의 분산도만으로 식품 중 산화형 폴리에틸렌 왁스의 분석은 어려울 것으로 판단되었다. MALDI-TOF/MS 분석 은 700~2,000 m/z에 peak가 관찰되었지만, 산화형 폴리에 틸렌 왁스 성적서에 적혀있는 분자량 범위인 2,700~2,800 m/ z와 큰 차이를 보여, MALDI-TOF/MS를 이용한 분석 역시 어려울 것으로 판단되었다. GC-FID를 이용한 지방산 분석 결과 산화형 폴리에틸렌 왁스 표준물질에서 과일 및 견과류에서 흔히 볼 수 없는 지방산인 C11:0, C15:1 지방산이 검출되었지만, 제외국 허용기준으로 첨가하여 분석하였을 때 관찰되지 않고, 고농도를 첨가할 경우에만 피크가 관찰되어 GC-FID를 이용한 분석은 어려울 것으로 판단되었다. FT-IR 분석결과 코팅된 견과류 시료와 코팅되지 않은 견과류 시료를 비교하였을 때 코팅된 시료에서 산화형 폴 리에틸렌 왁스 표준물질의 spectrum과 일치하는 spectrum 을 나타내어, 식품 중 산화형 폴리에틸렌 왁스의 분석은 FT-IR로 분석이 가능함을 확인하였다. 확립된 FT-IR 분석 법을 이용하여 국내외 대형마트에서 구입한 111건의 과일 및 견과류를 분석한 결과 산화형 폴리에틸렌 왁스를 사용한 시료가 없음을 확인하였다.

This purpose of this study was to investigate cooking characteristics of noodles prepared by adding 0, 2, 4 or 6 percent of Capsosiphon fulvescens to wheat flour containing konjac powder. Water binding capacity was significantly increased with increasing amounts of Capsosiphon fulvescens. Weight and volume of cooked noodles increased significantly in proportion with the amount of Capsosiphon fulvescens. Turbidity of the soup after cooking also increased with the addition of Capsosiphon fulvescens. Brightness(L) and redness(a) were decreased with addition of Capsosiphon fulvescens. Yellowness( b) increased. The color value of cooked noodles was decreased compared with that of wet noodles. Sensory evaluation scores revealed that cooked noodles with 4 percent addition group were highest in terms of color, flavor and overall acceptability. This study validates that addition of Amorphophallus konjac and 4 percent Capsosiphon fulvescens may improve functionality and preference of noodles.

This study investigated the nutritional compositions and physiochemical properties of three domestically cultivated jujube fruits (Boeun, Sangwhang, and Bokjo). Nutrient contents were analyzed by freeze-drying the jujube fruits. The results showed that the proximate compositions of the three jujube cultivars ranged from 7.85~13.52% for moisture, 4.65~5.24% for crude protein, 1.29~2.38% for crude ash, 0.17~1.09% for crude lipid, and 7.66~16.63% for crude fiber. The above proximate contents of jujube cultivars were significantly different. Mineral contents of Al, Fe, Mg, Ca, Na, and K in the three jujube fruits were also determined. Mn, Cu and Zn were not detected in any of the varieties. The content of Al was higher in Sangwhang, while Boeun had higher contents of Ca and K. The total polyphenol, ABTS values, and hypoglycemic effect were slightly higher in Boeun as compared to the other varieties. Taken together, Boeun could be an important source of natural antioxidant as a functional food.

Excessive body weight gain during the growth period of early life may predispose individuals towards obesity and metabolic disorder in later life. We investigated the possibility of using the food efficiency ratio as an early indicator for predicting susceptibility to diet-induced obesity and insulin resistance. Four-week-old, prepubertal, male Sprague Dawley rats were divided into obesity-prone and obesity-resistant groups based on food efficiency ratio values after five days on a high-fat diet. Metabolic parameters measured after 2, 6, and 10 weeks, and specific phenotypes were compared with each group. Obesityprone rats had higher increases in body weight and fat mass compared to obesity-resistant rats over the study period. Obesity-prone rats became glucose intolerant early in this study and remained so throughout the experimental period, with increases in fat weight and leptin levels occurring first, followed by increases in insulin level. Gluconeogenesis and insulin resistance significantly increased in obesity-prone groups in which activities of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase were increased and glucokinase activity decreased. Higher food efficiency ratio at an early age was closely correlated with body fat accumulation, hyperleptinemia, and hyperinsulinemia of middle and elderly age. We suggest a high food efficiency ratio in prepubertal subjects may be a useful predictor of future obesity and insulin resistance.

To increase the shelf-life of strawberry, samples were treated with two gel packs containing slow-released chlorine dioxide (ClO2) gas at 3~5 ppm for 6 days at room temperature and the changes in the major chemical components (ascorbic acid, polyphenols, flavonoids and anthocyanin) contents and antioxidative activities (DPPH, ABTS radical scavenging and metal chelating activity) were investigated. The content of ascorbic acid of control was 40.38 mg% and contained 35.67~44.75 mg% during 6 days. There was no tendency to increase or decrease during storage period. The contents of ascorbic acid of control and 3~5 ppm ClO2 gas treated samples were not significantly different during storage period. The content of polyphenol compounds of initial stage was 111.23 mg% and contained 117.78~132.40 mg% during 6 days. The contents of polyphenol compounds of 3~5 ppm ClO2 gas treated samples were 103.51~130.25 mg%. There were no significant different between them during storage. The flavonoids and anthocyanin contents were not different from the control during storage period regardless of 3~5 ppm ClO2 gas treatment. Furthermore, antioxidative activities were not different among the control and ClO2 gas treatments during storage.

To investigate the aroma and quality characteristics of wine bestowed by the degree of ripening of Cheongporang grapes, the general quality composition, color, organic acid, physiological activity, aroma component and sensory evaluation were analyzed. The general characteristics of the wine assessed were pH 3.34~3.50, total acidity 0.46~0.67%, color intensity 0.074~0.116, lightness 98.99~99.74, redness －0.39~0.01, and yellowness was 1.52~3.10. Malolactic fermentation was not relative to the contents of malic acid and lactic acid. The total polyphenol content and antioxidant activity were lowest in C3 wines made with ripe grapes and highest in C4 wines made with mixed grapes. Aroma analysis identified 6 alcohols, 15 esters and 5 miscellaneous compounds. Compounds with higher odor activity value (OAV) were 3-methyl-1-butanol, ethyl butanoate, isopentyl acetate, ethyl hexanoate, ethyl octanoate, ethyl decanoate and octanoic acid. The C4 wine, a mixture of grapes with different degrees of ripening, had the highest ester content and ratio. The lowest values were found in the C3 wine made with ripe grapes. Results of the sensory evaluation related the C4 wine, containing a large amount of ester compounds having high OAV values as the aroma component, as the best and most preferred wine.

This study investigated the effects of Goami 2 on the properties of Garaetteok. The moisture, crude protein, crude lipid and crude ash contents of the rice were 16.02, 5.40, 1.87 and 0.77%, respectively. The amylose contents (32.16%) and total dietary fiber contents (9.03%) were the highest in Goami 2. The water binding capacity of Goami 2 (167.84%) was higher than general rice flour. Using a rapid visco analyzer (RVA), the initial pasting temperature of Goami 2 was found to be the highest; also, the peak viscosities of Goami 2 were higher than general rice powder. To assess the effect of Goami 2 on the quality characteristics of Garaetteok, the rice-cake was made by adding various amounts of Goami 2 (0, 10, 20, 30, and 40% w/w) to rice. It was observed that higher the amount of added Goami 2, lower were the grades. In terms of the color values of Goami 2 addition, the L-values of Garaetteok were lower with increasing amount of Goami 2; addition of 40% Goami 2 had the lowest value. The textural properties (hardness) also showed that tteok containing the greater amounts of Goami 2 were considerably harder compared with the control. Sensory preference tests revealed that addition of less Goami 2 had the highest scores for appearance, color and overall acceptability, and the Goami 2 added was lower than control. Therefore, as compared to others cultivars, rice flour proved the most acceptable for the preparation of Garaetteok with cultivar rice.

This study investigated the crude protein and amino acid contents of local agricultural products widely and specifically grown in Korea, including 25 vegetables and 13 fruits. The crude protein content of vegetables and fruits ranged from 0.46 to 6.53% and 0.29 to 2.23%, respectively. Totally, 17 types of amino acids were found in most samples. The total amino acid content of vegetables and fruits ranged from 457.38 to 9,303.18 mg% and 368.82 to 3,118.75 mg%, respectively. The total amino acid contents of garlic and passion fruit was higher compared to other vagetables and fruits. The calibration curves of the standard components showed good linearity (r2>0.99), except Met (r2=0.989). The limits of LOD and LOQ were in the range 0.034 to 0.991 μg/mL and 0.009 to 0.474 μg/mL, respectively. The results of the study can serve as a fundamental source of information regarding crude protein and amino acids contents in food, for diet planning.

This research has attempted to investigate the volatile flavor compounds of onion products through acetic fermentation, and to create a natural beverage with beneficial biological properties which can also fulfill customer quality standards. Onion products (OAF (M): Onion extracts at five days of acetic fermentation, OAF (F): Onion extracts at ten days of acetic fermentation) were produced by acetic fermentation. Volatile flavor compounds from onion extracts, OAF (M) and OAF (F) were used by Mixxor liquid extractions and analyzed by GC/MSD. Compounds of 49, 75 and 69 were identified in onion extracts, OAF(M) and OAF(F) respectively. Among the major volatile flavor compounds classes, sulfur containing compounds (36.7%), acids (31.2%) and aldehydes (13.5%) in onion extracts were changed into acids (69.6%) and alcohols (24.6%) in OAF (M) and acids (80.6%) and alcohols (15.5%) in OAF (F). During acetic fermentation acetic acid, 1,3-butanediol (odorless) and 2,3-butanediol (onion flavor) increased remarkably, sulfur-containing compound such as 2,5-dimethylthiophene having anti-oxidant activities was detected by fermentation.

The purpose of this study was to investigate and analyze the total phenolic content (TPC), antioxidant activities (FRAP, ABTS, and DPPH), and antibacterial properties of lotus (Nelumbo nucifera) extracts. Lotus leaves, stems, and seed pods were extracted with deionized water at 95℃, and with 70.5% ethanol at 85℃. The TPC ranged from 8.12 to 215.12 GAE mg/g. The ethanol extract of the seed pod had the highest TPC, and the TPC of the corresponding deionized water extract was 161.45 mg/g. FRAP values ranged from 104.03 to 3,546.39 TEAC μmol/g, ABTS radical cation scavenging activities ranged from 105.11 to 3,956.94 TEAC μmol/g, and DPPH radical scavenging activities ranged from 37.29 to 2,549.46 TEAC μmol/g. EC50 values ranged from 0.26 to 9.63 mg/mL, and 0.31 to 21.21 mg/mL for ABTS and DPPH, respectively. The ethanol and deionized water extracts of the seed pod showed higher TPC and stronger antioxidant properties (FRAP, ABTS, and DPPH) than those of characteristic of the leaf extracts. The ethanol and deionized water extracts of the seed pod showed antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, and Pseudomonas aeruginosa with inhibition zones of 9.0 to 14.0 mm, and the ethanol extract of the leaf showed antimicrobial activity against B. subtilis and S. aureus with inhibition zones of 9.0 and 10.0 mm, respectively. Thus, the lotus seed pod could be used to produce novel teas, and could be a potential source of therapeutic ingredients for food and medicine.

This study investigated the needs to improve the quality of foodservice management in community child centers (CCCs), in accordance to the area where the CCC was located. The people in charge of foodservice management of 466 community child centers undertook a web survey, between July to August 2016. Most centers used menus from the Headquarters of Community Child Center (50.0%) or Center for Children’s Foodservice Management (34.1%). Factor analysis and multiple regression analysis were conducted to assess the requirement for improving the quality of foodservice management at the CCCs. Four factors were analyzed: ‘food material and facility management’, ‘administration management’, ‘menu management’, and ‘human resources management’. In large cities, ‘administration management’ and ‘menu management’ were found to affect quality improvement. In small cities, none of the factors assessed were effective in improvement. ‘human resources management’ had a significant influence on improving the quality of the foodservice in rural areas. The results of this study show that there was a difference in the quality improvement of the foodservice management in the centers, with respect to the location of the center. Therefore, this study can be used as basic data to establish the support policy for improving the quality of foodservice management in community child centers.
