Soybean [Glycine max (L.) Merr.), mungbean [Vigna radiata (L.) Wilcz.], cowpea [V. unguiculata (L.) Walp.], adzuki bean [V. angularis (Willd.) Ohwi & Ohashi], maize [Zea mays L.], sorghum [Sorghum bicolor (L.) Moench], sorghum $\times$ sudangrass [So bicolor intraspecific hybrid], and Japanese millet [Echinochloa crusgalli var. frumentacea (Link) W.F. Wight] were grown at two planting dates (18 June and 15 July) at Cheju in 1997 to select the best forage legumes adapted to Cheju Island for grass-legume forage rotation. Averaged across planting dates and cultivars, dry matter (DM), crude protein (CP), and total digestible nutrient (TDN) yields were 5,646, 1,056, and 3,637 kg/ha for soybean, 4,458, 676, and 2,661 kg/ha for mungbean, 3,289, 553, and 2,055 kg/ha for cowpea, 3,931, 674, and 2,489 kg/ha for adzuki bean, 12,695, 969, and 7,642 kg/ha for maize, 17,071, 1,260, and 8,857 kg/ha for sorghum, 16,355, 1,163, and 8,543 kg/ha for sorghum $\times$ sudangrass hybrid, and 8,288, 929, and 4,091 kg/ha for Japanese millet. Soybean was higher in CP, ether extract (EE), and TON content but was lower in nitrogen free extract content compared with the three other legumes. The legumes had much higher CP (13.7 to 21.9%), EE (2.42 to 6.23%), and TDN (58.7 to 69.9%) content but lower in crude fiber (CF) content (17.3 to 25.3%) than did the grasses tested except maize which had relatively lower CF content but higher TDN content. These results suggest that soybean could be the best forage legume for grass-legume forage rotation in the Cheju region.

Soybean meal was fermented by Aspergillus usami in order to reduce phytate content. Aflatoxin B1 was not detected in the fermented soybean meal. The contents of crude protein, crude fiber, ether extract and crude ash were slightly increased following fermentation with a concomitant reduction in nitrogen free extract. Though the fermentation partly degraded proteins in the soybean meal, there was small difference in amino acid composition between the soybean meal and the fermented soybean meal. The results showed that the fermentation did not affect nutritional value of protein in soybean meal. Approximately 55% of phosphorus extracted by trichloroacetic acid was inositol hexaphosphate (phytate) in the soybean meal. The content of inositol tetra to hexaphosphates was not detected in the fermented soybean meal. These results indicated that the fermentation almost completely eliminated phytate in soybean meal. Phytase activity was not detected in the unfermented soybean meal. However, the enzyme activity in the fermented soybean meal was 167.7 U/g. When the fermented soybean meal in supplemented in formula feeds, phytase in the fermented soybean meal might partly degrade the phytate in other ingredients in the digestive tract. The fermented soybean meal is possibly used as a phytate-free protein source of feed, which contains high available phosphorus.

The purpose of this study was to investigate the quality characteristics and antioxidative effect of Dasik prepared with Lycii fructus extract(LD). LD were added in ratios (w/w) of 0(C), 5(LD1), 10(LD2), and 15%(LD3), and then proximate compositions, physicochemical properties, sensory evaluations and antioxidative effect of the Dasik were measured. LD1~LD3 samples showed higher contents of moisture, crude lipid, crude protein and crude ash as well as pH and sugar content compared to control (p<0.001). The total phenol content of LD samples (LD1, 31.5% ; LD2, 66.1% ; and LD3, 69.7%) was higher than that of control (4.71%). DPPH radical scavenging activity of LD3 showed the highest activity of 65.3%, whereas that of control (27.0%) was the lowest among samples. Additionally, ABTS radical scavenging activity of LD samples was higher than that of control (C, 38.9% ; LD1, 53.6%; LD2, 80.5% ; and LD3, 83.3%). The results of texture analysis on all samples showed that control had the highest but LD3 was the lowest (p<0.001). In sensory evaluation, the scores of appearance, flavor, taste and overall preference for LD2 was significantly higher than the samples(C, LD1, and LD2). Form the findings, this study suggests that 10% addition of LD was effective for preparation of Dasik in the aspects of the consumer acceptability and functionality.

This study was carried out to investigate the amounts of voluntary intake, digestibility and nitrogen retention in Korean native goats (KNG) fed agricultural by-products containing rice straw (RS) and apple pomace (AP) and to obtain a basic information for establishing the feeding system of KNG. The result are as follows. 1. Among the chemical composition of experimental diets, the highest values in crude protein (CP ; 18.6%) and crude ash contents (10.7%) were observed in alfalfa hay. Those of RS+AP treatment were significantly low 6.0 and 4.8%, respecitively. Acid detergent fiber (ADF), ether extract and non-structural carbohydrate (NSC) contents were shown an adverse tendency. 2. Dry matter (DM) intakes per day in KNG fed RS+commercial diet (CD), RS+AP and RS+AP+CD were significantly lower (P<0.05) 210.3, 228.3, respectively than 358.1g in alfalfa hay. 3. DM intakes per basal weight expressed as DM g/kg of BW0.75 and DM g/kg of BW(%) were highest (P<0.05) 60.5g and 3.3%, respectively in KNG fed alfalfa hay, any other treatments showed 35.6 to 42.5g and 2.0 to 2.3%, respectively and this result was similar to those of DM intake per day. 4. Digestibilities of DM, organic matter, CP, ADF, neutral detergent fiber (NDF). crude ash and ether extract in alfalfa hay and RS+AP+CD treatment were significantly higher (P<0.05) than RS+CD treatment. Those of CP, ADF and NDF of RS+AP treatment in not significantly different with these treatments. 5. NSC digestibility was higher in alfalfa hay (66.7%) than those of other treatments (44.2~52.0% ; P<0.05). 6. Nitrogen retentions expressed as N retention(g) and N retention (%) in KNG were highest (P<0.05) 0.6g and 15.6%, respectively in RS+AP+CD treatment and RS+CD treatment was lowest (P<0.05) -06g and -21.4%, respectively.

This study assessed the quality of barley Dasik manufactured, according to traditional methods, with various levels of Maesil (Prunus mume) extracts at weight percentages of 0% (BD1), 10% (BD2), 20% (BD3), 30% (BD4), 40% (BD5). The Dasik were analysed with proximate analysis, a sugar content analysis, Hunter's color value test, mechanical characteristics test and a sensory evaluation. Increased ratios added Maesil extracts led to the moisture content, crude ash, and crude fat to significantly increase (p<.001). 10% (BD2) had significantly higher levels of crude protein (p<.01). Sugar contents was highest in 0% (BD1) and decreased as the amount of added Maesil extracts increased. This increase also led to higher L-values and b-values of chromaticity (p<.001) and the a-value of 0% (BD1) was significantly higher than the sample groups (p<.001). Changes in texture profile analysis, hardness and gumminess values were highest in the control group and the values of those in the sample group decreased with increasing amounts of Maesil extract (p<.001). It should be noted that, among the samples evaluated, barley Dasik that contained 10% Maesil extract (BD2) had the highest commercial value.

This study investigates the chemical components and biological activities in Picrasma quassioides (D.Don) Benn. extracts for the purpose of developing natural pharmaceutical products. The proximate components in Picrasma quassioides (D.Don) Benn. extracts were 81.56% of carbohydrate, 5.80% of crude fat, 7.75% of crude protein, and 2.07% of crude ash. Calcium was the most predominant mineral and followed phosphorus, potassium, sodium, and magnesium, in a decreasing order. The content of the unsaturated fatty acids, such as oleic acid, linoleic acid, and linolenic acid, was find to be higher than those of saturated fatty acids. Water and methanol extract exhibited antioxidative activity with $IC_{50}$ of $128{\mu}g/ml$ and $144{\mu}g/ml$, respectively, suggesting that the extracts are the major biological component in Picrasma quassioides (D.Don) Benn. extracts. The ${\alpha}-glucosidase$ inhibitory activity showed that methanol and water extract were the high inhibitory activity. Considering these results, water extracts of Picrasma quassioides (D/Don) Benn. showed the possibility that they can be used as a new material for natural pharmaceutical products.

The purpose of this study was to investigate the quality characteristics and descriptive analysis of Yanggaeng prepared with Lycii fructus extract (LD). LD were added in ratios (w/w) of 0 (C), 1.5 (LY1), 3.0 (LY2), 4.5 (LY3), and 6% (LY4), and then proximate compositions, physicochemical properties, and sensory evaluations of the Yanggaeng were measured LY1~LY4 samples showed higher contents of crude lipid, crude protein and crude ash as well as $^{\circ}Brix$ compared to control (p<0.001). pH and lightness (L) of samples decreased as the LD increased. With regard to the texture of Yanggaeng samples, the scores of hardness, adhesiveness, springness, and cohesiveness was significantly increased by the Addition of LD (p<0.05, p<0.01). For the descriptive analysis, ten panelist generated and evaluated 29 sensory attributes for the Yanggaeng, and there were significant differences among the samples for all 26 sensory attributes. For the descriptive data, principal component analysis (PCA) was performed to summarize the sensory characteristics of the Yanggaeng. The results of PCA showed that the positive attributes, e.g. savoury, were closely in relationship with LY2 and LY3. Form the findings, this study suggests that 3~4.5% addition of LD was effective for preparation of Yanggaeng in the aspects of the consumer acceptability.

This study was performed to investigate the inhibitory effects of brown algae extracts on histamine production in mackerel muscle. First, antimicrobial activities of brown algae extracts against Morganella morganii were investigated using a disk diffusion method. An ethanol extract of Ecklonia cava (ECEE) exhibited strong antimicrobial activity. The minimum inhibitory concentration (MIC) of ECEE was 2 mg/ml. Furthermore, the brown algae extracts were examined for their ability to inhibit crude histidine decarboxylase (HDC) of M. morganii. The ethanol extract of Eisenia bicyclis (EBEE) and ECEE exhibited significant inhibitory activities (19.82% and 33.79%, respectively) at a concentration of 1 mg/ml. To obtain the phlorotannin dieckol, ECEE and EBEE were subjected to liquid-liquid extraction, silica gel column chromatography, and HPLC. Dieckol exhibited substantial inhibitory activity with an $IC_{50}$ value of 0.61 mg/ml, and exhibited competitive inhibition. These extracts were also tested on mackerel muscle. The viable cell counts and histamine production in mackerel muscle inoculated with M. morganii treated with ${\geq}2.5 $ MIC of ECEE (weight basis) were highly inhibited compared with the untreated sample. Furthermore, treatment of crude HD-Cinoculated mackerel muscle with 0.5% ECEE and 0.5% EBEE (weight basis), which exhibited excellent inhibitory activities against crude HDC, reduced the overall histamine production by 46.29% and 56.89%, respectively, compared with the untreated sample. Thus, these inhibitory effects of ECEE and EBEE should be helpful in enhancing the safety of mackerel by suppressing histamine production in this fish species.

In this study, we investigated the effects of ostrich extract combined with Korean herb medicine(OEKHM) on the serum parameters in carageenan induced paw edema in rats. Carageenan causes enhanced edema formation which contributes to the pathophysiology of inflammation. Male Sprague-Dawley rats were used. There were four groups of treatments: OEKHMs and the control. After treatment with oral doses of 3 mL/180 g BW. 3 kinds of OEKHMs were processed which were ostrich bone with flesh meat with herb medicine(BFH), ostrich bone with flesh meat(BF), and ostrich bone with internal organs(BI). The contents of crude fat of the BFH was lower, but crude protein and crude ash of the BFH were significantly higher than those of the BF and the BI. In case of the levels of minerals(Ca, P, Mg, Fe, Cu and Zn ) of the BFH were significantly higher than those of BF and BI. And the heavy metals(Pb and Cd) were not detected in the OEKHM. The serum level of triglyceride in the BFH treated group decreased compared to that of the edema induced group. The serum levels of HDL-cholesterol concentration in the BFH supplemented group increased compared to that of the other groups. The serum levels of minerals(Ca, Mg, Fe, Cu and Zn) of the BFH treated group significantly increased than those of other groups(p<0.05).

The study is a pioneering effort to determine the mineral, nutritional, and phytochemical composition and phenolic content and to determine the free radical scavenging activity of Gigantochloa levis (Blanco) Merr, a native bamboo species (locally known as "bolo") in the Philippines. Proximate analysis showed that air-dried G. levis leaves contain 15.8% ash, 22.6% crude protein, 1.2% crude fat, 29.3% crude fiber, and 19.7% total sugar. Phytochemical tests indicated the presence of diterpenes, triterpenes, saponins, phenols, tannins, and flavonoids in both the ethanolic and aqueous leaf extracts, while phytosterols were only detected in the ethanolic extract. Folin-Ciocalteu assay determined the total phenolic content in gallic acid equivalents (GAE) to be $85.86{\pm}3.71$ and $32.32{\pm}1.01mg\;GAE/100g$ dried sample for the ethanolic and aqueous extracts, respectively. The total phenolic content in quercetin equivalents (QE) was $74.44{\pm}3.11$ and $29.43{\pm}0.85mg\;QE/100g$ dried sample for the ethanolic and aqueous extracts, respectively. The radical scavenging activity of the different solvent fractions containing varying concentrations of the extract was determined using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The ethyl acetate and 1-butanol fractions were found to have the highest radical scavenging activity. Mineral analysis via Energy Dispersive X-Ray Spectrometry (EDS) of the ash of G. levis leaves showed that Si is the major component, followed by K and Mg. These results point to the potential of G. levis leaves as a source of minerals and bioactive compounds with medicinal value.
