Abstract

This study was done to analyze the contents of minerals and to investigate the ratio of measured values to labeled values and to analyze the ratio of calcium to other minerals in 68 specimen with minerals - fortified commercial beverages, noodles, cereals and grain products. Content of calcium, iron and zinc in samples after microwave digestion was analyzed with an ICP-OES. The measured values of calcium were ranged 82.2~293.1% of the labeled values in 38 samples composed calcium - fortified commercial beverages, noodles, cereals and grain products. The measured values of iron and zinc were ranged 83.3~301.0%, 90.1~314.1% of the labeled values in minerals - fortified commercial beverages, noodles, cereals and grain products, 42, 24 samples. The Ca : Fe ratios were 90.55 (50.55~220.64) in fruit & vegetable juice, 850.41 in fruit & vegetable beverage, 553.49 in blended beverage, 179.07 (118.37~238.01) in soy milk, 204.39(41.64~397.52) in noodle, 296.97(121.64~868.88) in fried noodle, 30.89(15.69~62.05) in cereal and 7.73(0.22~49.92) in grain product. The Ca : P ratios were 1.44(0.96~1.98) in fruit & vegetable juice, 1.92 in fruit & vegetable beverage, 1.66 in blended beverage, 4.23(2.25~7.72) in soy milk, 1.14(0.28~1.97) in noodle, 1.88(1.17~2.42) in fried noodle, 1.29(0.87~2.92) in cereal and 0.30(0.06~1.57) in grain product. The Ca : Mg ratios were 1.85(0.87~5.04) in fruit & vegetable juice, 28.72 in fruit & vegetable beverage, 2.97 in blended beverage, 5.27(2.93~9.36) in soy milk, 3.97(1.34~7.57) in noodle, 6.77(4.63~10.78) in fried noodle, 4.40(2.30~12.55) in cereal and 1.17(0.23~7.48) in grain product. These results suggest calcium contents and the ratio of calcium contents to other minerals in calcium-fortified food products should be strictly controlled. Moreover, to avoid problems with Excessive nutrition, there must be initiatives for better understanding on food labelling and nutrition for fortified food.

본 연구는 무기질이 강화된 식품(음료류, 면류, 시리얼류, 곡류가공품) 68건에 대하여 무기질류의 함량을 분석하여 표시량에 대한 검출량의 비율을 조사하였고 칼슘과 다른 무기질의 비율을 분석하였다. 칼슘, 철, 아연의 함량은 마이크로웨이브 장치로 분해 후 ICP-OES로 분석하였다. 칼슘을 강화한 음료류, 면류, 시리얼류, 곡류가공품 38건에 대한 칼슘의 검출량은 표시량의 82.2~293.1%이었다. 무기질류를 강화한 음료류, 면류, 시리얼류, 곡류가공품에 대한 철(42건)과 아연(24건)의 검출량은 각각 표시량의 83.3~301.0%, 90.1~314.1%이었다. 칼슘과 철의 분자량비는 과채주스 90.55(50.55~220.64), 과채음료 850.41, 혼합음료 553.49, 두유류 179.07(118.37~238.01), 국수 204.39(41.64~397.52), 유탕면류 296.97(121.64~868.88), 시리얼류 30.89(15.69~62.05) 그리고 곡류 가공품 7.73(0.22~49.92)이었다. 칼슘과 인의 중량비는 과채주스 1.44(0.96~1.98), 과채음료 1.92, 혼합음료 1.66, 두유류 4.23(2.25~7.72), 국수 1.14(0.28~1.97), 유탕면류 1.88(1.17~2.42), 시리얼류 1.29(0.87~2.92) 그리고 곡류가공품 0.30(0.06~1.57)이었다. 칼슘과 마그네슘의 중량비는 과채주스 1.85(0.87~5.04), 과채음료 28.72, 혼합음료 2.97, 두유류 5.27(2.93~9.36), 국수 3.97(1.34~7.57), 유탕면류 6.77(4.63~10.78), 시리얼류 4.40(2.30~12.55) 그리고 곡류가공품 1.17(0.23~7.48)이었다. 이와 같은 결과로 칼슘의 함량과 칼슘 강화식품에서 칼슘과 다른 무기질들의 비율에 대한 엄격한 관리가 필요하고 또한 과도한 영양 문제를 방지하기 위해 영양강화식품의 식품 표시 및 영양에 대한 더 많은 이해 방안이 모색되어야 한다는 것을 제안할 수 있다.
