To furnish basic data for the utilizatin of camellia(Camellia japonica L.) seeds as a raw material of industrial products, major chemical components of camellia and defatted camellia seeds were investigated. The moisture, crude ash, crude fat and crude protein contents of camellia seeds were 4.06%, 1.83%, 65.75% and 8.44%, respectively. Defatted camellia seeds indicates that it contains 10.31% moisture, 5.28% crude ash and 17.49% crude protein while no crude fat was detected. The curde ginseng saponin, crude saikosaponin and red ginseng saponin contents of camellia seeds were 108.0mg%, 0.4mg% and 40.3mg%, respectively. Total amino acid contents of camellia seeds and defatted camellia seeds were 7,851mg% and 13,002mg%, respectively, and the major amino acids were glutamic acid, arginine, aspartic acid and leucine. The ratio of essential/total amino acid of camellia seeds was 0.29.

Purpose: Lycium ruthenicum Murr. is a nutritional food that has been used widely for treatment of heart disease, abnormal menstruation, and menopause. Methods: In this study, the crude protein, crude lipid and crude ash contents of two different Lycii fruits with different colors were investigated, and their color values, total sugar, pH, total anthocyanins and total carotenoids were analyzed. Results: Regarding crude ash, crude fat and crude protein contents, the L. barbarum showed higher in crude fat and crude protein contents than black fruits, whereas L. ruthenicum showed higher contents than black fruits. Regarding mineral composition, mineral contents were in the other of K, Mg, Mn, Na, Zn, and Fe. The K content was high in all of the samples, and the contents of Cr and Cu were not measured. The pH values of L. ruthenicum and L. barbarum were $5.00{\pm}0.01$ and $5.08{\pm}0.02$, respectively. The total sugar content of L. ruthenicum was 45.45% while that of L. barbarum was 45.43%. Ascorbic acid content of L. barbarum was $50.86{\pm}3.63%$ while that of L. ruthenicum was $6.3{\pm}1.40%$. The total anthocyanin content of L. ruthenicum was $462.22{\pm}0.41mg/100g$, although no anthocyanin was detected in L. barbarum. The total carotenoids content was $812.25{\pm}6.01mg/100g$ in L. barbarum, although that of L. ruthenicum was not measured. Conclusion: The results from this study indicate that there is a large difference in the composition of functional ingredients of L. ruthenicum and L. barbarum. There is a strong possibility of L. ruthenicum to be developed into color food sources.

The contents of crude protein were high and those of crude fat were low with the contents of crude ash, crude protein, and crude fat being 1.61, 18.50, 0.04 g/100 g respectively. Vitamin A was not detected and the contents of vitamin C and vitamin E were 3.85 and 3.04 mg/100 g, respectively. The calcium, potassium, magnesium, iron and sodium contents were 222.0, 117.90, 24.12, 2.30, 555.90 mg/100 g respectively. Rice bread contains 9 essential amino acids such as valine, leucine, isoleucine, methionine, threonine, lysine, phenylalanine, histidine, and arginine. The analysis of rice bread fatty acid showed 58.04 mg/100 g of saturated fatty acid, 26.31mg/100 g of monounsaturated fatty acid and 15.64 mg/100 g of polyunsaturated fatty acid. The total essential fatty acid content was 15.49 mg/100 g. With the rising interest in processed rice products, well-being, and diet, it is necessary to develop processed rice foods that are nutritional and low in calories using rice powder that is nutritionally better than flour.

In result of chemical properties of bamboo shoots and changes of chemical components of salted bamboo shoots during 120 days salting, the contents of moisture crude fat tannin and ascorbic acid were decreased but those of crude protein curde ash and salt concentration were increased. The main free amino acids of bamboo shoots were serine arginine alanine leucine and tyrosine. The content of total free amino acid was rapidly decreased in 80days-past of salting and after that slowly decresed. Wang bamboo shoots was the highest as 1060.18mg/100g in content of total free amino acid. The main mineral elements were K, P, Na and Mg. The contents of Fe and K were the hihest among them. The contents of P, Fe, Zn. Mn. Ge and Cu were decreased but K, Mg, Na and Ca were increased during salting. When fresh bamboo shoots were compared with salted bamboo shoots fresh bamboo shoots contained the contents of moisture crude protein crude fat tannin and ascorbic acid more than salted bamboo shoots did but the less the contents of ash fiber and salt concentration.

This study was attempted to compare the nutritive value of leaf with stem of the water cress Oenanthe stolonifera DC. in order to improve the eating habits and as a part of studying on the effective curing nutrients for the damaged liver. The contents of moisture crude proteinon the effective curing nutrients for the damaged liver. The contents of moisture crude protein crude fat and crude ash were 90.40% 2.85%, 0.42% and 0.74% in leaf while the contents of moisture crude protein crude fat and crude ash were 95.15% 0.77% 0.09%, and 0.64% of moisture crude protein crude fat and crude ash were 95.15% 0.77% 0.09% and 0.64% in stem respectively. The quantitative fractionation of proteini of both leaf and stem ranked albumin the highest content followed globulin prolamin and glutelin in order. It has been sh-own by SDS-polyacrylamide gel electrophoresis that water extractable protein of leaf 11 bands but those of stem were not detected. The scope of molecular weight for the main protein of water extractable protein of leaf was between 34.700 and 45,000. The amounts of extractive-nitrogen from leaf and stem of the water cress were 241.02mg% and 271.67mg% respec-tively. The amounts of free amino acid-nitrogen from the leaf and stem were 89.02mg% and 32.02mg% respectively. In free amino acid-nitrogen from the leaf and stem were 89.02mg% and 32.02mg% respectively. In free amino acid composition of both leaf and stem the major components were aspartic acid and glutamic acid. In total amino acid composition of water cress leaf aspartic and glutamic acid were the major components. Whereas alanine and thr-eonine were the major components in stem The assessment of water cress leaf and stem with chemical score. EAAl Rl showed that the values of stem were lower tendancy than those of leaf. Limiting amino acid of leaf was tryptophan while that of stem was lysine.

This study was carried out to investigate the influence of the seeding dates on the yield and feed value in cultivating Italian rye grass on paddy soil. The field experiment was designed in a randomized block design of 3 repetitions with seeding dates of Oct. 19 (T1), Oct. 26 (T2), Nov. 2 (T3), Nov. 9 (T4), and Nov. 16 (T5) treatments. Plant length, fresh yield, dry matter yield and TDN yield were increased with early seeding dates (p<0.05). Crude protein, Crude fat and crude ash were increased with early seeding dates (p<0.05). On the other hand, NDF, ADF and Crude fiber were decreased with early seeding dates (p<0.05). Total mineral contents were higher in the order of T4 > T3 > T5 > T1 > T2 (p<0.05). The total composition amino acid content was decreased significantly (p<0.05) as the seeding dates delayed. Total free sugar content was highest in T1, whereas the lowest in T5 treatment (p<0.05). Nutrition yields (crude protein, crude fat, amino acid and free sugar) were increased significantly with early seeding dates (p<0.05). The above result indicated that it is favorable to seed soon after rice harvest to increase dry matter yield and nutrition yield of Italian ryegrass in the midlands.

The objective of this study was to develop the classification method of various organic wastes. Specifically, the effects of proximate composition on the biogas production and degradation rates of agricultural by-production was investigated and a new standards for mixture of various organic wastes based on proximate composition combination was developed. Agricultural by-products (ABPs) with medium total carbohydrate, medium crude protein and low fat contents demonstrated the single step digestion process. ABPs with low total carbohydrate, high crude protein and high fat contents demonstrated the two step digestion process of Diauxic growth. The single ABP (Class No. 15) and the mixed ABPs (Class No. 12+18, 6+12+22, 9+12+18) after 10days showed the similar biogas yield pattern. We can use the classification method for the more ABPs and organic wastes from factory and municipal waste treatment plant for the high efficient biogas production.
