This study evaluated th physicochemical and sensory characteristics of teriyaki sauce added with bitter melon (Momoridaica charantia L.) roasting powder. Teriyaki sauce containing Momoridaica charantia L. roasting powder at concentration of 0% (control), 2% (RMT2), 4% (RMT4), 6% (RMT6), 8% (RMT8). Color of teriyaki sauce added with Momoridaica charantia L. roasting powder were lower than the control. The pH of the sauce ranged from $4.31{\pm}0.01{\sim}4.87{\pm}0.01$. As the amount of added Momoridaica charantia L. roasting powder was increased, total soluble solid content and viscosity of teriyaki sauce increased. DPPH and ABTS radical scavenging activities of Momoridaica charantia L. added teriyaki sauce increased. The sensory evaluation was performed with scoring test s for color, flavor, taste, bitter taste, and overall acceptability by 50 professional panelists. In sensory evaluation, teriyaki sauce added with 4% Momoridaica charantia L. roasting powder concentrate high score in sensory preference. Based on the results, 4% should be recommended as the optimum level of Momoridaica charantia L. roasting powder concentrate to be added for the preparation of teriyaki sauce.

Eighteen Holstein Friesian ${\times}$ Native heifers with an average live weight of $175.4{\pm}27.8kg$ were allotted to 3 dietary groups. All animals were kept individually in a stanchion barn with free access to water and urea-treated rice straw (UTS). The supplemented feeds were as follows: Group (Gr) 1 - concentrate mixture (15% CP) at 1% body weight (BW), Gr 2 - concentrate mixture at 0.7% BW + free licking of multinutrient block (MNB), Gr 3 - as Gr 2 + 0.3% BW ground com. Multinutrient block composed of 20% mineral mixture, 10% urea, 18% molasses, 20% soybean meal, 22% sesame meal, 10% cement, 0.15 million IU and 50 IU/kg MNB of vitamin A and E. The experimental period lasted 12 weeks. The result revealed that MNB enhanced intake of UTS and total dry matter intake. Animals in Gr 3 consumed a higher amount of feed than the other 2 groups, thus resulting in the highest live weight gain and tended to possess the best feed conversion ratio. Heifers in Gr 2 also performed better than Gr 1 although the difference was not significant. Average MNB intake found to be 0.65 kg/day. Feed cost per kg gain was not significantly different amon groups. However if the cost of MNB could be lower, it would benefit the production cost of animals. The advantage of MNB is the safety of using a high level of urea. Although it was supplemented to UTS which also contained non-protein nitrogen (NPN), no toxic sign was shown. The results indicated that MNB could be partially substituted to concentrate mixture and it was even better when used incombination with soluble carbohydrate feed.

Alkali-soluble extracts were prepared from medium-sized barks of Radiata pine(Pinus radiata). There are difficulties in the production of extracts with uniform quality and in the preparation of adhesives with suitable viscosity. Ultrafiltration using an Amicon cell was subjected to fractionate extracts according to molecular sizes in order to overcome the above problem. The filtration efficiency was studied by using thin channel filtration systems. Adhesive manufacturing was also examined. Removal of particles greater than 0.45m from the extracts increased both filtration speed (flux) and yields of solids in the filtrates. Ultrafiltration with PM 10 membrane was very effective to fractionate and concentrate the extracts. Stiasny precipitates from the filtrates obtained by PM 10 membrane were very lower than that(83%) of the retentates. This ultrafiltration method was efficient for obtaining high yield purified phenolic compounds(mainly polyflavanoids) and thus important for preparing wood adhesives from barks. The extracts were shown excessive high viscosities at the concentrations required for adhesive formulation, but this high viscosity and short gelation time was reduced by lowering pH of the extracts and addition of urea. The highest bonding strength of plywoods(340g/$m^2$ of adhesive spreads) was achieved with adhesive formulated by 100parts of mixed alkali extracts and urea(70/30,w/w), 10parts of p-formaldehyde and 3.5parts of wheat flour at pH 6, and by hot pressing at the conditions of 12kg/$cm^2$ at $120^{\circ}C$ for 10 minutes.

Effects of extrusion processing on zinc bioavailability in a product made from 85% semolina and 15% soy protein concentrate were determined using in vitro and in vivo techniques. Soluble and dialyzable zinc contents of the extruded product were 15.3 and 13.0 $\mu$g/g, respectively, compared to 15.6 to 15.0$\mu$g/g in the raw (unprocessed) ingredients. Zinc bioavailability in diets in which all of the zinc (14ppm) was provided either by the extruded product or by its raw ingredients was determined in two groups of male Sprague Dawley rats. No differences were found in concentrations of zinc in plasma, liver and femur between rats fed the two experimental diets. Apparent zinc digestibility was similar for both diets. These results are consistent with the in vitro results showing no effect of extrusion processing on zinc bioavailability.

Objective: This study was realized to evaluate the effects of supplementation with blends of water and fat-soluble vitamins on animal performance and carcass traits of young Nellore bulls. Methods: Forty-three Nellore bulls, with an initial weight of 261±27.3 kg and a mean age of 8±1.0 months, were used. Five animals were slaughtered at the beginning of the experiment (reference group), to determine the initial empty body weight of the bulls that remained in the experiment. The remaining 38 bulls were fed ad libitum and distributed in a completely randomized design in a 2×2 factorial scheme, with or without supplementation of water-soluble (B-blend+ or B-blend-) and fat-soluble (ADE+ or ADE-) vitamin blends. Diets were isonitrogenous (120 g of crude protein/kg dry matter [DM] of total mixed ration) and consisted of a roughage:concentrate rate of 30:70 based on total DM of diet. The experiment lasted 170 days, with 30 days of adaptation and 140 days for data collection. At the beginning and end of the experimental period, the bulls were weighed to determine the average daily gain. To estimate the apparent digestibility of nutrients and microbial efficiency, spot collections of feces and urine were performed for five consecutive days. Results: DM, ashes, organic matter, crude protein, ethereal extract, neutral detergent fiber corrected for residual ash and residual nitrogenous, and N intake and apparent digestibility were not influenced by vitamin supplementation, but total digestible nutrients intake and non-fibrous carbohydrates digestibility were influenced by B complex vitamin supplementation. Nitrogen balance, microbial efficiency, and performance data were not influenced (p>0.05) by vitamin supplementation. Conclusion: Vitamin supplementation (a blend of water-soluble and fat-soluble vitamins or their combinations) does not influence the animal performance and carcass traits of young Nellore bulls.

본 연구에서는 감식초의 유효성분 손실은 최소화하면서 음용시 느껴지는 이취인 톡쏘는 향과 맛을 약화시켜 섭취하기 부드럽게 하고, 좋은 식품소재로서 감식초의 활용도를 높이기 위해서 감식초 농축액을 제조할 때 진공농축 정도에 따라 변하게 되는 이화학적 특성들을 조사하여 적정 농축방법을 확립하는데 기초자료로 활용하고자 하였다. 감식초를 진공농축시킴에 따라 색도, 점도, pH, 산도, 유기산함량, 유리당 함량과 같은 이화학적 특성들은 큰 차이를 나타내는 것으로 나타났다. 위의 결과들을 종합해 볼 때 음용시의 기호도와 다른 식품소재로서의 활용도를 높이기 위한 감식초의 농축정도는 $30^{\circ}Bx$ 이하로 진공농축하여 음용시 이취나 이미로 작용하는 너무 강한 톡쏘는 맛과 향을 어느 정도 제거시켜 적당한 맛과 향을 유지하게 하고 유효성분을 최대한 보존시키는 것이 좋을 것으로 판단된다.
