  • We investigated mineral difference from mushroom Phellinus linteus and Phellinus baumii on mulberry, oak and elm. ICP test, The major mineral components were K, Ca, and Fe, while Mg, Na, P, Cr, Mn, Cu and Zn were determined as micro mineral components. In case of P.linetus and P.baumii the component of K was shown as 699.0mg/100g and 630mg/100g, in oak, 340.7mg/100g and 314.6mg/100g in elm, and 311.6mg/100g and 311.6mg/100g in mulberry respectively. In Ca, mulberry fruiting body were shown about 2 times highest and expecially in case of Na was oak fruiting body were shown as 10 times highest as against the others sample groups. In micro mineral components, Zn component was shown very diffeence about sample groups. We concluded that the highest mineral component of K was shown in mushroom cultivated on oak of both P.linetus and P.baumii. As a results, mineral component has showed very difference on cultivated to timber. According to the results of mineral component we concluded that Phellinus linteus and Phellinus baumii has mineral component different depending on timber.

  • This study was undertaken to determine the changes in amino acids, amylose and mineral contents of Jeolpyons(Korean rice cake) supplemented with various levels of roasted soybean flour (RSF). Amino acids content of Jeolpyons increased as RSF content increased. Especially the contents of total essential amino acids of Jeolpyon supplemented with RSF(5, 10, 15 and 20%) increased 1.22 to 2.74 times greater than those of the ocntrol. Amylose, which is related to retrogradatin effect on rice products decreased about 0.9 to 4.7% by increasing the soybean flour contents. Mineral contents by jeolpyon containing RSF increased as RSF contents increased.

  • The experiment was conducted to study the effect of activated charcoal on the fatty acid composition, meat color and mineral contents of chicken meat with 48 birds of broiler for 6 weeks by adding 0%, 0.6%, 0.9% and 1.2% of activated charcoal to broiler diet. The activated charcoal level of 0.6% and 0.9% increased significantly oleic acid and arachidonic acid contents compared to control(p<0.05). L*, a*, b* values were not influenced by the added level of activated charcoal, however and a* value of different parts of chicken meat was significantly different(p<0.05). The activated charcoal diet increased significantly(p<0.05) the calcium, magnesium and phosphorus content of chicken meat, and tended to increase total mineral contents. In conclusion the activated charcoal supplements to chicken diet increased oleic acid, arachidonic acid the total mineral contents.

  • Proximate components, minerals, vitamins and chlorophyll contents were determined in vegetables purchased at Garak-dong market and organic vegetables cultivated at Hongchun, Kangwon-do. The vegetables were Kale, Angelica Keiskei Koidz, Celery, Lettuce and Allium fistulosum. In proximate component contents, analyzed crude protein and fat contents of organic vegetables were higher than those of general vegetables. Organic vegetables had strong green color. Minerals such as sodium, potassium, calcium, phosphorus, iron as well as vitamins were determined. Contents of minerals and vitamins in organic vegetables were higher than those of general vegetables. Total mineral content of organic and general kales were 811.8 mg/l00g, and 688.1 mg/l00g, respectively. Total mineral content of organic Angelica Keiskei Kowz, Celery, Lettuce and Allium fistulosum were 447.9, 486.5, 368.6, and 320.9 mg/100g, respectively.

  • To manufacture of high-performance semi-structural double-sided adhesive tape, 2-ethylhexyl acrylate (2-EHA) and acrylic acid (AAC) were used, and the syrup was prepared by UV irradiation in this study. The effects of the thickness, various inorganic filler contents, and filler types on the semi-structural properties of acrylic double-sided adhesive tape were investigated. The peel strength increased with increasing thickness and wetting time. In case of the thin thickness (under $250{\mu}m$) with decreasing true density of inorganic filler, the peel strength increased with increasing wetting time. The initial peel strength showed a higher value at a big size of inorganic filler, and the filler's size in adhesive tapes was confirmed by SEM images. The peel strength and dynamic shear strength increased as a proportional relationship with various inorganic fillers and contents, and these inorganic fillers in $0.1{\mu}m$ thickness indicated more effect on the dynamic shear strength of double-sided adhesive tape. From these results the thin acrylic double-sided adhesive tape determined to be use for applications as a high-performance semi-structural.

  • This study was carried out to investigate the chemical composition and the inorganic constituents of the green tea at the 3 picking periods (Ujeon, Sejag, Jungjag) in Hadong. The results as follows ; The contents of chlorophyll, tannin, vitamin-c and total catechin were increased as picking periods increased but the contents of total nitrogen, total free amino acids, theanine and caffeine were decreased on the reverse. The inorganic constituents Mg, Ca and Mn were increased as picking periods getting late but the Na, K, B contents were decreased on the reverse. The contents of the total nitrogen, chlorophyll, total free amino acid, theanine, caffeine and total catechin and Na, Mg, Ca, B and Se were insignificant differences between Ujeon and Sejag.

  • The objective of this study was carried out to elucidate the effect of LEDs (light emitting diodes) irradiation in relation to early growth and inorganic elements in leaf lettuce (Lactuca sativa L. 'Rollo Rosa'). In morphological changes of leaves, shoot elongation and hypocotyl length showed poor growth in red light irradiation, while the red + blue light irradiation induced shorter plant height and much greater leaf numbers resulting in increased fresh weight. In change of the Hunter's color and SPAD values, lettuce seedlings grown under in red + blue and fluorescent light irradiation had a higher $a^*$ value, otherwise SPAD values were not changed in these light irradiations. Interestingly, relative chlorophyll contents showed 1.8 times increased redness in the treatment of red + blue light irradiation. Inorganic element (N, Ca, Mg, Mn, and Fe) and ascorbic acid contents were increased in lettuce plants grown under LEDs light irradiation compared to those of lettuce grown under the fluorescent light which showed higher P and Mn contents. In conclusion, it is considered that red + blue light irradiation which stimulates growth and higher nutrient uptake in leaf lettuce could be employed in containers equipped with LEDs.

  • The nutritional composition of Fomitopsis pinicola (F. pinicola) fruiting body has been analyzed for medicinal and edible uses. The contents of crude fibers, carbohydrates, crude protein, moisture, crude fats and ashes were 43.3%, 26.3%, 12.8%, 12.6%, 3.3% and 1.7%, respectively. Eighteen amino acids were found in F. pinicola. Among total amino acids, glutamate content was the highest (457 mg/100 g dry mushroom) and arginine, glycine, valine, aspartate and isoleucine were followed. Concerning free amino acids, glutamine, arginine, trytophan, and glutamate were dominant. The vitamin E content was the highest (276 mg/100 g dry mushroom), then vitamin H and vitamin B, were followed. The mineral contents were as follows: K 165.06 mg, P77.57 mg, Mg 46.11 mg, Fe 21.56 mg, and Ca 16.90 mg based on 100 g dry mushroom.
