This study aimed to investigate the effect of acorn powder and starch on the blood parameters of mice fed a high-fat diet. The moisture, crude ash, crude protein, and crude fat contents of acorns were 37.99±0.37%, 1.61±0.06%, 4.36±0.18% and 3.22±0.15%, respectively. Acorn powder and starch contains antioxidant minerals such as selenium and zinc. The iron content was significantly higher in acorn powder than in acorn starch (p<0.05). The total cholesterol concentration was 148.50±29.72 mg/dL in the high-fat starch diet (HFS) group, while in the high-fat diet (HF) group it was 201.50±39.15 mg/dL (p<0.05). Serum LDL-cholesterol concentrations were significantly lower in the HFS group (50.50±10.79 mg/dL) than in the HF group (62.00±20.85 mg/dL; p<0.05). The serum IL-1β levels in mice were not significantly different between the groups. IL-10 levels were higher in the HFP group than other groups. There is a need for strong recognition that acorns are good ingredients worldwide. It is required to develop various products using acorn powder and starch powder. There is also a need for a strategy to globalize food using acorns.

The mushroom Agrocybe chaxingu was analyzed to evaluate the nutritional value of this potential food. The moisture content was 88.9% in the fruiting body of A. chaxingu, and the proportions of ash, crude fiber, carbohydrate, crude protein, and crude fat were 0.9%, 1.4%, 7.2%, 2.5% and 0.4% by weight, respectively. A. chaxingu contained 1.29 mg/100 g edible weight of vitamin , and the contents of vitamin , vitamin , and vitamin C were 0.15 mg, 0.32 mg, and 18.4 mg per 100 g of wet mushroom. Potassium (3,318 mg/100 g, dry basis) was found at the highest concentration in A. chaxingu. In addition, the mushroom contained many other minerals (all figures are mg per 100 g of dried mushroom) such as phosphorus (909.7), magnesium (141.3), sodium (12.7), zinc (7.4), iron (6.5), copper (2.8), manganese (0.8), and nickel (0.1). The results indicate that A. chaxingu is a valuable nutrient source.

우산나물의 식품학적 가치와 기능성 식품 소재로서의 개발 가능성을 검토하기 위하여 우산나물의 지상부와 뿌리에 함유된 수용성 단백질과 당, 아미노산, 무기질 그리고 폴리페놀과 플라보노이드 화합물의 함량을 측정하였다. 지상부의 수용성 단백질은 210.36 mg%였으며 뿌리는 870.42 mg%, 환원당은 지상부 848.12 mg%, 뿌리 1,420.91 mg%, 그리고 유리당은 각각 14.85 mg%와 355.00 mg%로 뿌리의 glucose 함량이

To produce several high-quality species of Chwinamul (Aster scaber, A. Tataricus, Ligularia fischeri), leaves of the plants grown in different natural habitats were anlayzed. Contents in vitamin C and β-carotene were generally higher in plants grown in the field. However, Aster scaber picked form Yongwol and A. tataricus from Mt.Taryong contained relatively higher vitamin c and β carotene. Crude protein and fat contents varied depending on the growing area. Ca content was markedly higher in the plants grown in the natural havitats.
