Employment rate of married women has increased in Korea, but working housewives still have the main responsibility for the household chores in double income families. Due to the busy life, dietary habit of working housewives might be poorer than full-time housewives. The purpose of this study was to compare dietary habits and food frequency between full-time housewives and working housewives. The subjects were 119 full-time housewives and 164 working housewives living in chungbuk. Age, education level and monthly income were significantly different between the two groups, but health-related habits such as smoking, drinking, and exercise did not differ. While full-time housewives had higher tendency to have breakfast and dinner everyday than working housewives, they had lower tendency to have lunch everyday than working housewives. The highest response rate for preparation time for dinner was 40~60 min in full-time housewives and 20~40 min in working housewives. Most of food frequency consumed by full-time housewives was higher than by working housewives, especially bean and bean curd, kimchi, salty cracker, and candyㆍchocolate. Education should be provided to recommend to have regular meals without skipping and to show the fast ways to prepare meals with various foods.

This study was conducted to investigate association of salt preference by salty taste assessment and self-recognition, and frequencies of selected foods. A total of 290 college students (89 males and 201 females) participated salty taste assessment and questionnaire survey in May 2012. For salty taste assessment, samples were made by adding sodium chloride to soybean sprout soup at five different concentrations: 0.08%, 0.16%, 0.31%, 0.63%, 1.25%. Among those, the participants were asked to select the most preferred sample. Self-administered questionnaire was consisted of questions about self-recognition on salt preference and frequencies of basic food groups and processed foods commonly consumed by college students containing high sodium, sugar, and fat. While 43.8% and 19.3% of the students preferred 'salty' and 'unsalty', respectively, by salty taste assessment, 40.4% and 13.1% recognized their preferred taste as 'salty' and 'unsalty', respectively, by questionnaire. Salt preference by salty taste assessment was significantly correlated with salt preference by self-recognition. Male students who recognized themselves as 'eating salty' consumed ramyon, retort foods, doughnut, cake, ice cream more frequently and green leafy vegetables less frequently than those 'eating unsalty'. Female students who recognized themselves as 'eating salty' consumed fast foods more frequently and milk and green leafy vegetables less frequently than those ‘eating unsalty'. Our results show that preference by self-recognition was associated with frequencies of some foods, and that students who preferred salty taste consumed unhealthy foods such as high sodium, sugar and fat more frequently.

유아의 장내 균총 정상화에 유용한 새로운 발효유제품을 개발하고자 본 실험을 수행하였다. 신생아 분변시료에서 2,200균주를 분리하고 348 균주의 16S rRNA를 분석한 결과, 유산균의 37.8%가 E. faecalis로 확인되었다. 가장 많은 유전자형을 나타낸 E. faecalis 중에서 MRS 액체배지에서 가장 생장이 우수한 E. faecalis KACC 91532를 선발하였다. 선발 유산균을 이용하여 전통식품인 타락죽을 발효하고 이화학적, 관능적 특성을 분석하였다. 타락죽의 발효시 E. faecalis KACC 91532는 $6.14{\pm}0.19$에서 $7.36{\pm}0.13$ Log CFU/mL로 증가하여, 섭취량과 E. faecalis가 건강기능식품기준 및 규격에 고시되어 있는 점을 고려시 건강기능식품으로 판매가 가능하며, 특히 유아의 장내 균 총 정상화에 기여할 수 있을 것으로 생각된다. This study was conducted to develop an effective probiotic dairy product to normalize the microbial flora in Korean infants. A total of 2,200 colonies were isolated from 25 Korean neonates, and 16S rRNA of 348 isolates was analyzed. Approximately 40% of the lactic-acid producing bacterial isolates were Enterococcus faecalis, and 34.2% of them were strains similar to XR7 in the GenBank database. The fastest growing strain in MRS broth was registered as 91532 by the KACC. The selected strain was freeze-dried and utilized to ferment a milk-containing rice soup, tarakjuk. Microbiological, physico-chemical, and sensory characteristics of the fermented tarakjuk were compared with fermented milk and tarakjuk. E. faecalis KACC 91532 increased from $6.14{\pm}0.19$ to $7.36{\pm}0.13$ Log CFU/mL, and can be useful as a probiotic, as described in the Standards for Functional Health Foods.

An HPLC analytical method was validated for the quantitative determination of biogenic amines in agricultural products. Four agricultural foods, including apple juice, Juk, corn oil and peanut butter, were selected as food matrices based on their water and fat contents (i.e., non-fatty liquid, non-fatty solid, fatty liquid and fatty solid, respectively). The precision, accuracy, recovery, limit of detection (LOD) and quantification (LOQ) were determined to test the validity of an HPLC procedure for the determination of biogenic amines, including tryptamine, β-phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine and spermine, in each matrix. The LODs and LOQs for the biogenic amines were within the range of 0.01~0.10 mg/kg and 0.02~0.31 mg/kg, respectively. The relative standard deviation (RSD) of intraday for biogenic amine concentrations ranged from 1.86 to 5.95%, whereas the RSD of interday ranged from 2.08 to 5.96%. Of the matrices spiked with biogenic amines, corn oil with tyramine and Juk with putrescine exhibited the least accuracy of 84.85% and recovery rate of 89.63%, respectively, at the lowest concentration (10 mg/kg). Therefore, the validation results fulfilled AOAC criteria and recommendations. Subsequently, the method was applied to the analysis of biogenic amines in fermented agricultural products for a total dietary survey in Korea. Although the results revealed that Korean traditional soy sauce and Doenjang contained relatively high levels of histamine, the amounts are of no concern if these fermented agricultural products serve as condiments.

Somatic cell counts (SCCs) of goat milk can vary widely depending on the counting methods used and non-pathogenic factors; the goat milk industry can be threatened by establishment of a legal standard based on the findings in cow milk. In Korea, SCCs have been excluded from the items that are analyzed under the "Livestock Products Processing and Composition Standards" in accordance with a recent NVRQS Notice amendment. From April to October, SCCs of 150 goat milk samples from 2 farms were analyzed using a Somascope calibrated with standard goat milk samples. Average SCCs of the samples was 598,000/mL, and significant differences were not found between farms and between breeds. SCCs increased from 3 to 8 months after delivery.
