This study investigated the changes in the nutraceutical lipid components of brown rice oil after germination. Four different high-yielding cultivars (Dasan1, Segyejinmi, Hanareum1 and Hanareum2) of Korean brown rice were selected and brown rice oil was extracted from each cultivar before and after germination. Free fatty acid, squalene, policosanols, and isomers of phytosterol were analyzed using GC, and isomers of tocols (tocopherol and tocotrienol) and γ-oryzanol were quantified using HPLC from both brown rice oil (BRO) and germinated brown rice oil (GBRO). The contents of phytosterol isomers, campesterol, stigmasterol, and β-sitosterol were increased by 8.3%, 31.6%, 3.3% in GBRO, respectively. Furthermore, the squalene content showed the highest increase of up to 2.4 fold in GBRO compared to BRO. In addition, linoleic and linolenic acid composition increased whereas oleic and palmitic acid decreased in the GRBO. However, the contents of tocols (tocopherol and tocotrienol) in GBRO were lower than those in BRO, and there was no significant difference in policosanol and γ-oryzanol between GBRO and BRO. These results suggest that GBRO has the potential as a healthy and functional source due to its lipid profile on improved lipid metabolism.

The core ingredient of traditional Korean style soy sauce is soy bean without any wheat or rice incorporated. National brands as well as regional micro-brewed companies constitute the soy sauce market in Korea. The present study investigated the physico-chemical and sensory properties of soy sauces produced by small-scale or mass-production. Additionally, the key physico-chemical parameters sufficiently representing the critical sensory characteristics have been identified. Ten types of soy sauce brewed by the Korean traditional method were selected for the study. Among these samples, seven types were brewed in small-scales in the Gyeonggi-do region whereas the other 3 types were mass-production products of major national brands. The total solid, reducing sugar, salinity, sugar content, amino nitrogen, CIELAB, acidity, and pH of soy sauce samples were measured for the physico-chemical analysis. A generic descriptive analysis was conducted to analyze the sensory characteristics of the samples using six trained panelists. The descriptive panel developed 21 sensory attributes. The data were statistically analyzed using ANOVA, PCA and PLSR. Overall, the micro-brewed products showed significantly higher value of salinity and acidity but lower content of reducing sugar than the mass-production products. The micro-brewed soy sauces elicited stronger fermented flavor, sourness, and bitterness whereas the national brand products elicited stronger alcoholic odor, sweetness and umami taste. Sugar content, acidity, and amino nitrogen showed strong relationships with fish sauce flavor, umami taste, and rich flavor. Salinity was closely related to the overall flavor intensity.

This study was carried out to analyze the relationship between body mass index (BMI) and general characteristics, psychological factors, eating habits, dietary behaviors, and health related quality of life using survey of 335 women aged 20 to 29 years in the Seoul and Kyungin areas. The 335 study subjects were divided into 4 groups by BMI (㎏/㎡) levels; normal group(18.5≤BMI≤22.9), overweight group(23.0≤BMI≤24.9), mild obesity group(25.0≤BMI≤29.9), and heavy obesity group (BMI≥30) by Asian-Pacific obesity index criteria. The family income of the heavy obesity group was significantly (p<0.05) less than that of the normal weight group. Psychological factors, such as stress and depression of the normal weight group tended to be higher than those of overweight and obesity groups. The higher BMI level had the lower self-efficacy(p<0.05) among all subjects. As the BMI level increased, the preference for sweet, salty, and hot taste was significantly high. We found that normal weight women had healthier eating habits and dietary behaviors and a higher level of health-related quality of life than did those who were overweight, mildly obese, and heavily obese women. Overweight and mildly and heavily obese women were strongly associated with decreased physical and mental health related quality of life. Therefore, weight loss is desirable, and is likely to be beneficial for health-related quality of life in obese adult women. In conclusion, this study contains evidence to suggest that obesity management programs including different strategies according to obesity are required to determine the types of programs that are suitable for adult women, prior to their initiation of a program. The findings are helpful to inform researchers and practitioners who are seeking to implement appropriate strategies to create positive changes in the health behaviors of obese adult women.
This study was conducted to examine the effects of Opuntia ficus-indica complex (OF) on the lipid metabolism, bile acid in feces, alanine aminotransferase (ALT) activity, aspatate aminotransferase (AST) activity, composition of urine and expression of cholesterol related mRNA in streptozotocin (STZ)-induced diabetic rats. Thirty two male Sprague-Dawley rats were randomly divided into non-diabetic control (NC), diabetic control (DC), diabetic OF of 2% (OF-2) and diabetic OF of 5% (OF-5), then each group was fed for 3 weeks. Plasma total cholesterol, non-esterified fatty acids (NEFA), total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL) were decreased significantly (p<0.05) in OF-5 group compared to DC, but high density lipoprotein (HDL) was not changed. AST and ALT were also reduced and bile acid excretion was improved. Composition of urine in OF-5 was almost same in NC. The expression of cholesterol 7α-hydroxylase (CYP7A1), 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA-R), Low density lipoprotein receptor (LDL-R) mRNA indicated that feeding OF have the effects of cholesterol decreation in plasma by synthesis of bile acid from cholesterol. These results provide experimental evidence about improved lipid metabolism of the OF feeding in the STZ-induced diabetic rats.
This study was performed to investigate the characteristics of nutrient intake according to metabolic syndrome in Korean elderly. Data on 1,200 elderly (men 545, women 655) over 65 years was obtained from the Korea National Health and Nutrition Examination Survey 2010. The subjects were divided into metabolic syndrome (MetS) and normal groups based on NCEP-ATP III guidelines and by applying the Asia-Pacific definition with waist circumference. The prevalence of MetS was 48.9% in all subjects, 35.6% in men and 58.9% in women, respectively. All nutrient intake was significantly lower in MetS than normal subjects, except iron, vitamin A, carotene, and retinol. In the carbohydrate: protein: fat (C:P:F) ratio, MetS showed a higher rate for carbohydrate, but a lower rate for protein and fat than normal. MetS was lower in calcium, vitamin B1, and vitamin C by the nutrient adequacy ratio than normal. Mean adequacy ratio of MetS (0.69) was lower than that of the normal group (0.72). These results demonstrated that undernutrition, not excess intake of specific nutrients - energy, fat, or cholesterol was associated with the risk for MetS in Korean elderly with MetS. Therefore, it is recommended to have a healthy dietary pattern with diverse nutrients for the prevention of MetS.
This study was conducted to evaluate the effect of various types of functional brown rice milk porridge, which has been popular as a fast yet nutritional food, to promote rice consumption and to examine the best ratio and recipe. Each sample contained 10, 20, 30, and 40% brown rice compared to non-glutinous rice and sweet rice and were applied to mechanical and sensory tests. The moisture content of both non-glutinous rice and sweet rice porridges increased with increasing brown rice content. The viscosity of non-glutinous rice milk porridge decreased as with increasing brown rice content, whereas the viscosity of sweet rice milk porridge increased with increasing brown rice content. The pH was highest for BRT0 at 6.74 and lowest for BGT0, which is sweet rice porridge with brown rice, at 6.27. The sweetness decreased significantly for both sweet rice and non-glutinous rice porridges with the increase in brown rice content. The brightness of weet rice and non-glutinous rice porridges with brown rice increased significantly (p<0.001) with the increase in brown rice content, while the redness and yellowness of the color increased significantly (p<0.001) with increasing in brown rice content. As a result of analyzing the preference in the milk porridge containing brown rice, BRT30, which is non-glutinous rice milk porridge with brown rice, was most preferred at 5.8 in terms of color, while BRT30 was most preferred at 6.2 in terms of fragrance. All samples containing brown rice powder were highly preferred in terms of taste and the overall preference of sweet rice milk porridge was highest for BRT30 (5.8). The overall preference was highest for BGT30 at 6.1 and the preference was generally higher for the experiment groups prepared with sweet rice as opposed to those prepared with non-glutinous rice. Also, the scores for the sensory test were higher when brown rice was added. Therefore, it was concluded that the milk porridge could quickly and easily be prepared with brown rice instead of non-glutinous rice or sweet rice.

As for the preferences for seafood, ‘like (67.6%)’, ‘fair (21.5%)’, and ‘dislike (7.3%)’ were observed. Concerning the frequency of seafood consumption, 4th grade students showed higher frequency of ‘1~2/week’ compared to others (p<0.05). 6th grade students showed higher frequency of ‘3~4/week’ compared to others (p<0.05). In terms of preferable cooking methods for seafood, ‘grilling (35.0%)’, ‘soup (23.0%)’, and ‘raw fish (19.8%)’ were observed. Boys showed a higher preference for ‘grilling’, ‘frying’ and ‘raw fish’ compared to the girls (p<0.05). Girls showed a higher preference for ‘soup’, ‘braising’ and ‘steaming’ compared to the boys (p<0.05). As for the seafood intake by eating place, ‘home (60.1%)’, ‘eating-out (18.3%)’, and ‘school lunch menus (12.8%)’ were observed in that order. Therefore, in order to increase the consumption and intake of seafood, students should attempt to achieve proper intake though information of nutrition and consistent nutritional education.

This study was conducted to investigate the anthropometric data, nutrient intakes and serum profiles in premenopausal and postmenopausal women living in Gyeonggi-do Province, Republic of Korea. The subjects were 49 premenopausal women and 63 postmenopausal women who are not taking any hormone or cardiovascular drugs. Anthropometric measurements were taken by a trained practitioner and the data for dietary intakes were obtained by a 24-hour recall method. Serum samples were collected and analyzed for the total cholesterol, triglyceride (TG) and lipoprotein fractions. The mean age of the premenopausal women was 45.17±3.28 years and that of the postmenopausal women was 62.52±4.14 years. The height and weight were 157.86±4.35 ㎝, 58.75±6.01 ㎏ in premenopausal women and 156.42±3.62 ㎝, 57.63±5.38 ㎏ in postmenopausal women, respectively. WHR (waist hip ratio) in postmenopausal women was significantly higher than that of premenopausal women (p<0.05). There were no differences between the pre-and postmenopausal women in the intakes of energy, protein, fat, Ca, Fe, vitamin A, vitamin B1, vitamin B2, niacin, vitamin C and vitamin E. However carbohydrate and Na intakes in postmenopausal women were significantly higher than those of premenopausal women. In postmenopausal women, Ca intake was below and Na intake was extremely high considering KDRIs (Dietary Reference Intakes for Koreans). Serum triglyceride in postmenopausal women was positively correlated with age, BMI (body mass index) and WHR. Serum total cholesterol and triglyceride in postmenopausal women showed significantly negative correlations with fiber intake. These results suggest that it is necessary to help postmenopausal women maintain a healthy body weight. Postmenopausal women needs to increase Ca (calcium) intakes and diet quality by decreasing the intakes of Na (sodium). In addition, an adequate intakes of fiber is recommended for postmenopausal women to prevent cardiovascular disease.
This study was performed to estimate the salt content and evaluate the nutritional quality of free lunch meals served by welfare facilities for the elderly. We collected food items from 8 welfare facilities in Gyeonggi-do, and calculated the total salt content from the salinity and weight of individual food items. The average salt content from lunch meals was 5.68 g, which was over the recommended daily salt intake by the WHO. The greatest contributor to the salt content among the menu groups was soup and stew (37.5%). Soup, stew, deep-fried foods, and sauces were major sources of salt, while the most salty dishes were sauces, deep-fried food, salt-fermented food, and kimchi. The nutrient content was sufficient, except for calcium in both men and women, which was equal to approximately 1/3 of the dietary recommended intakes (DRIs) for Korean adults of their mean age. In addition, the index of nutritional quality (INQ) and nutrient adequacy ratios (NAR) of most nutrients were satisfactory, except for those of calcium and sodium. The INQs of calcium and sodium were 0.64 and 4.41, respectively, while the mean adequacy ratio of a meal was 0.95. These results suggest that multilateral efforts to lower sodium intake be considered and calcium sources be added, in order to improve the quality of meals served to the elderly at welfare facilities.
본 연구에서는 매실의 첨가에 따른 돼지막창의 품질특성 변화를 확인하였다. 가열하지 않은 막창(생막창)과 100℃에서 10분 동안 가열한 막창(가열막창)의 pH는 매실의 첨가에 따라 낮아졌다. L값과 a값은 생막창과 가열막창 모두 저장기간에 따른 변화는 미미한 것으로 확인되었다. 생막창의 b값은 저장 초기에는 매실의 첨가에 따른 상승이 확연하였으나, 저장기간이 지속됨에 따라 그 차이가 점점 줄어들었다. 가열막창의 b값은 매실의 첨가에 따른 b값이 약간 낮아졌으며, 저장기간에 따라 약간 감소하는 경향을 나타내었다. ΔT 값은 생막창과 가열막창 모두 L값과 거의 유사한 패턴을 보였다. 생막창과 가열막창 모두에서 TBA가는 매실의 첨가농도에 비례하여 유의적으로 낮아졌으며, 매실 5% 첨가구와 10% 첨가구는 거의 TBA가에서 차이가 없었다는 것으로 확인되었다. VBN가는 매실을 첨가할 경우 생막창과 가열막창 모두에서 VBN의 증가속도는 대조구에 비해서 낮은 것으로 확인되었다. 저장 6일째부터 매실의 첨가농도에 비례하여 VBN가가 낮아졌으며, 매실을 5% 첨가할 경우 저장을 4일 이상 지연시킬 수 있는 것으로 확인되었다.

The physical properties of jellified soybean curd residue (Biji) with the addition of various gums were investigated to optimize the direct availability of a by-product of the tofu production process. The lightness (L value) of the jellified Biji prepared with various gums was approximately 77~80, regardless of the concentration of gum used. Especially at the concentration of 0.1% and 0.3%, a pectin showed a significantly higher value compared with other gelling agents (carrageenan and agar). The strength of samples prepared on the basis of carrageenan showed the value of 335~569 g/㎠ and 234~335 g/㎠ according to the addition of locust bean gum and xanthan gum, respectively. On the other hand, the samples made with pectin and agar were 134~272 g/㎠ and 50~215 g/㎠, respectively. Where locust bean gum was used as a viscous agent, the adhesiveness of sample prepared by adding carrageenan was greater than those made with pectin or agar. The values were -6.0~-11.0 g, -2.7~-10.2 g and -3.7~-7.0 g, respectively. Overall, the strength and adhesiveness of samples according to increase of the added amount of Biji showed constantly increasing trend regardless of the type of gelling agent used. In the sample containing carrageenan this trend was most noticeable.
