  • The mineral content of Tricholoma matsutake was evaluated for comparison of mineral contents according to the area of cultivation. Ten domestic and thirty Chinese (10 Yanji, 10 Yunnan and 10 Tibet) T. matsutake specimens were assessed using an atomic absorption spectrophotometer (AAS) and inductively coupled plasma mass spectrometer (ICP-MS). The Na, Mg, K, and Ca contents of domestic T. matsutake were 128.12±85.25 mg/kg, 218.52±105.35 mg/kg, 7,534.58±2,691.52 mg/kg, and 17.69±7.14 mg/kg, respectively, while those of Yanji T. matsutake were 124.89±57.24 mg/kg, 64.07±27.52 mg/kg, 1,439.18±311.04 mg/kg, and 10.88±4.52 mg/kg, respectively. The Na, Mg, K, and Ca contents of Yunnan T. matsutake were 90.78±23.23 mg/kg, 77.40±28.36 mg/kg, 1,446.29±126.33 mg/kg, and 28.42±5.18 mg/kg respectively, while those of Tibet T. matsutake were 143.50±41.54 mg/kg, 124.64±50.18 mg/kg, 3,530.95±2,714.99 mg/kg, and 21.05±8.71 mg/kg, respectively. The Cu contents of domestic, Yanji, Yunnan, and Tibet T. matsutake were 105.43±32.97 mg/kg, 19.92±8.95 mg/kg, 54.51±16.91 mg/kg, and 64.80±23.01 mg/kg, respectively. Both domestic and Chinese T. matsutake samples showed significantly different K, Mg, and Cu levels in this study. Therefore, a comparative evaluation of the K, Mg, and Cu contents of multiple domestic and Chinese T. matsutake varieties is needed to determine the appropriate area of cultivation in the future.

  • The objective of this study was to investigate the extent of total sugar and sodium in 129 different kinds of bakery products, breads and cookies, sold at bakeshops in Seoul metropolitan area. The bakery products produced by bakeshops on a small scale were not applied by clauses of mandatory nutrition label for children's taste food. All types of free sugars -fructose, glucose, sucrose, lactose and maltose- were detected in breads, but only fructose and sucrose were detected in cookies. The average amount of sucrose per 100 g of breads was 6.24 g, of cookies was 30.03 g. Breads and cookies amounting to 100 g of sample contained total sugar of 11.19 g and 30.38 g, respectively. The average amounts of sodium in breads and cookies were 120.71 mg/100 g, 70.76 mg/100 g, respectively. When the contents of total sugar in breads and cookies per one serving size were compared to WHO guidelines, the percentages were 15.7% and 18.2% about recommended daily intake of total sugar of 50 g. When it come to sodium, the bakery products had range of 1.1-6.5% to 2000 mg of daily intake of sodium recommended by WHO.
