This study was performed to investigate 172 samples of fried food in fast food store. The free fatty acid value of 22 samples exceeded standard of fried-food. These samples were 10 fried chickens, 6 fried potatoes and 5 fried onions. Fatty acid composition differed from each company. The correlation between free fatty acid value and double bond index was very low. New standard of fried food in fast food store is needed for thorough hygiene management, because of being not existed standard. The fried potato containing many carbohydrate and fat appeared higher calory than fried chicken containing many protein. The fried food had high fat comparatively, so that attention in regard to excess intake is demanded. The trace materials were included Mg, Ca, Mn, Fe, Zn, Cu and Cr in order of quantity, and the harmful heavy metals-Pb, Hg and Cd- were included small quantity.

BACKGROUND/OBJECTIVES: This study aimed to examine the food security status of urban poor adolescents and its association with diet quality. SUBJECTS/METHODS: A cross-sectional survey was conducted among 188 adolescents aged 13-18 yrs living in Kuala Lumpur, Malaysia. Household food insecurity and dietary intake data were collected using the Radimer/Cornell hunger and food insecurity instrument and 2-day 24-h dietary recalls, respectively. Diet quality was determined using the Malaysian Healthy Eating Index (HEI). Weight and height were measured and body mass index-for-age, as well as height-for-age z scores were calculated. RESULTS: The present study revealed that 47.9% of the adolescents experienced household food insecurity, 24.5% experienced individual food insecurity, 18.6% household food security, and 9.0% child hunger. The mean score of diet quality was 56.83 ± 10.09, with a significantly lower HEI score among food insecure adolescents (household food insecure, individual food insecure, and child hunger) than household food secure adolescents (P = 0.001). The differences between food secure and food insecure households were found to be significant for energy (P = 0.001) and nutrients including proteins (P = 0.006), carbohydrates (P = 0.005), dietary fiber (P = 0.001), folate (P < 0.001), and vitamin C (P = 0.006). The multiple linear regression showed that adolescents who experienced food insecurity (β = -0.328; P = 0.003) were found to be significantly associated with poor diet quality (F = 2.726; P < 0.01), wherein 13.3% of the variation in the diet quality was explained by the food security status. CONCLUSIONS: Experiencing food insecurity contributed to poor diet quality among urban poor adolescents. Further longitudinal studies are needed to comprehensively understand this association to improve food insecurity and diet quality among urban poor communities.

Constructs with seven latent evaluation indicators and 18 observable survey questions were developed by food and nutrition experts to calculate a food safety recognition and practice index for children. The purpose of this study was to suggest statistical approaches to test construction validity on the constructs, obtain weights of the evaluation indicators, and develop questionnaires to calculate a children's food recognition and practice index. Survey data of 2,400 elementary fifth grade students were used as empirical results. Test validity was evaluated by exploratory factor analysis and confirmed to be highly significant by confirmatory factor analysis [i.e., linear structural relations (LISREL) analysis]. Standardized path coefficients of the LISREL analysis were suggested based on weights, and the weights were compared using the AHP and Delphi methods.

This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

Food is a kind of unconditional element for the health and survival of humanity. Eating is the most principle desire for humans among others, which can make humans feel stability and pleasure when the desire is well satisfied. The attention to food safety is increasing and food safety accidents are happening constantly, which makes the anxiety to food safety become more serious. Especially after the WTO, the floating of food hazards between countries are increasing, which makes the problems of food safety not just limited to inland but has become a matter of common interest internationally in this liberalization era. Therefore, institutional preparation and persistent management and supervision are necessary for increasing dietary life satisfaction as well as securing food safety. Meanwhile, the consumers also need to understand and trust the food safety information, and have the ability of personally pursuing a safe diet. In this study, sentiment index about food safety and dietary satisfaction were centered on Korean consumers and the factors having an effect on dietary satisfaction were analyzed. Moreover, whether the reliance to food safety information had a moderating effect on the sensory level of food safety and satisfaction to dietary food was also confirmed. The main results were different with those concluded by J. Yun and S. Joo (2014). The sensory level of food safety was decided by the reliance to food production distribution provision safety, anxiety to food varieties, and food token. The reliance to food production distribution provision safety was lower than the average level. The anxiety to food varieties was slightly higher than the average level. The reliance to food safety information was generally lower than the medium level which showed the distrust to food safety information. The satisfaction of diet by the consumers showed a slightly lower level than the average level. In addition, the reliance to food safety information had a moderating effect on the sentiment index about food safety and dietary satisfaction. Therefore, the consumer organizations or the government should actively expand various consumer education related to food safety in order to apprehend the concrete variables which can have effects on the satisfaction of diet and transform the precise information into accurate knowledge.
