This study was done to analyze the contents of minerals and vitamins to compare the measured values of minerals, vitamins with labeled values of them in food labeling and to investigate the ratio of measured values to labeled values in 437 specimen with minerals and vitamins - fortified commercial beverages and liquid teas. Content of calcium and sodium in samples after microwave digestion was analyzed with an ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer) and vitamins were determined using by HPLC (High Performance Liquid Chromatography). The measured values of calcium were ranged 80.3~142.6% of the labeled values in 21 samples composed calcium - fortified commercial beverages and liquid teas. In case of sodium, measured values were investigated 33.9~48.5% of the labeled values in 21 sports beverages. The measured values of vitamin C, vitamin B2and niacin were ranged 99.7~2003.6, 81.1~336.7, 90.7~393.2% of the labeled values in vitamins - fortified commercial beverages and liquid teas, 57, 12, 11 samples. To support achievement of the accurate nutrition label, there must be program and initiatives for better understanding and guidances on food labelling and nutrition for food manufacture.

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.
