  • This study was carried out in order to utilize ginseng marc (GM), a byproduct produced during the preparation of ginseng extract. For the utilization of GM as coffee-replacing beverage, GM was roasted at 140-23$0^{\circ}C$, for 10-30 min to generate coffee-like flavor and taste. The physicochemical changes in GM induced by roasting process was measured. Weight and moisture contents of GM abruptly decreased while roasting at various temperature and period of time, and the amount of water-extracted solid substances decorated beyond 23$0^{\circ}C$. Among the proximate components, total and free sugar decreased remarkably, while crude fat content increased. Crude protein content did not change by the roasting process. pH derides to pH 4.9 after 30 min at 20$0^{\circ}C$, but increased at higher temperatures. Hunter color L value of the GM powder decreased, whereas a and b values, increased up to 10 times as compared to that of the control. The brown color(O, D 490 nm) in 50% ethanol extract of the roasted GM was 46 times higher than that of the control.

  • Pork patties were formulated with either steam-dried green tea power or freeze-dried raw tea leaf powder, and the quality characteristics of these products were monitored. Proximate analysis of tea powder contained 17.80~19.85%, 4.70~5.73%, and 5.60~5.77% (as is) crude protein, crude fat, and crude ash, respectively. There were no significance differences in pH among the samples. Chromaticity tended to decrease brightness ($L^*$) and redness ($a^*$), and there were significant differences in yellowness ($b^*$) as the added amount of tea power was increased. For texture, hardness increased as more green tea powder was added. Thiobarbituric acid reactive substances (TBARS) and volatile basic nitrogen (VBN) values increased after storage for 12 days, whereas samples formulated with green tea powder showed lower TBARS and VBN values compared to control groups. Sensory panelists showed preference for samples with green tea powder added compared to the control group.

  • The botanical, chemical composition and dry matter digestibility of collected herbage samples from sheep fitted esophageal fistula were compared to those of offered herbage samples by the sown pasture, oversown pasture and forest pasture at the 3rd flush stage (25cm grass height). Experimental fields was treated by one plot design and lasted from Aug. 1987 to Oct. 1987 at Chungnam National University, Daejon. The results obtained are summarized as follows: 1. The botanical composition of collected herbage samples was different from offered herbage samples and this difference seemed to depend on diet selection. 2. The sheep consistantly selected more ladino clover than orchardgrass and tall fescue. 3. Crude protein content of collected herbage samples was high (P<0.01) and NDF content was low (P<0.01) on the sown and oversown pastures but forest diets contained more crude fat content (P<0.05) and less crude protein and NDF content (P<0.01) than offered herbage samples. 4. Dry matter digestibility of collected herbage samples was higher than offered herbage samples (P<0.0 1) and this difference was found out among pasture types.

  • The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resources. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants(Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae fructus) and we examined the effects of drink on physiological function in aorta relaxation. Thus, the effect of developed beverage on phenylephrine induced contraction of isolated rat thoracic aorta. Contractile force was measured with force displacement transducer under 1.5g loading tension. Brix, pH and titratable acidity of developed drink were 9.5%, 3.3 and 0.22%. The approximate nutritional composition of beverage was carbohydrate, 5.98%, crude protein, 0.70%, crude fat, 0.20% and crude ash, 0.20%. Developed beverage contained K(4.00 ㎎%), Na(3.68 ㎎%), Ca(2.54 ㎎%), Mg(1.60 ㎎%) and Fe(0.29㎎%). The contraction forces by injection of phenylephrine in isolated thoracic aorta were significantly low in each experimental groups compared with control groups, These results that developed drink with medicinal plants can be used as a functional material to decrease aorta contraction.

  • Nutrients and hormone levels of dried pig placenta were studied. Placentas were freeze-dried (FD), oven-dried at 60 (OD-60), and 90$^{\circ}C$ (OD-90) and then crushed by a blender into small pieces. FD and OD-60 pig placenta had a higher moisture content than did OD-90, with no difference between FD and OD-60. There were no large differences in compositions of crude protein, crude fat, and crude ash of dried placenta among the treatments and the contents of K, Fe, and ${\alpha}$-tocopherol were highest in FD (p<0.05). Glutamine and glycine were the most abundant amino acids in all dried placenta and tyrosine was highly retained in FD placenta, compared with OD (p<0.05). Estradiol was the major sex hormone, followed by progesterone and testosterone in all dried placentas. Antibiotics including amoxicillin, sulfamethazine, tylosin, and chlorotetracyclin were not detected from the pig placentas tested. These results demonstrate that placenta is a good biomaterial with high nutritional quality, and that freeze drying is superior to oven drying for processing pig placenta.

  • We evaluated the quality characteristics of Kimbugak prepared using a microwave oven or the oil-frying puffing method with different contents (0%, 15% and 30%) of Capsosiphon fulvescens in dried laver. Microwave-processed Kimbugak had lower crude fat content but higher levels of crude ash, crude protein, and minerals than that prepared by oil-frying; it also had higher hardness values. The redness of Kimbugak containing 30% C. fulvescens processed using either method was lower than the control group. In sensory evaluations, participants preferred Kimbugak containing 30% C. fulvescens puffed by oil-frying. These results indicate that Kimbugak puffed using the oil-frying method has the best quality characteristics.

  • An investigation evaluating the preparation and physicochemical properties of sauce with various herbs(sancho, sage, and rosemary) derived from soy sauce was performed. The effects of the different kinds of herbs added to sauce for roasted mackerel were assessed using physiochemical, sensory, flavor, and texture analysis properties. This fish was then compared to, fish with salt. The moisture, crude protein, crude fat, and crude ash content of the roasted mackerel were significantly higher than the control(p<0.05, p<0.001). The salinity content of the herb sauce added samples were significantly higher than the control(p<0.05). Conversely, the pH and peroxide value of the herb sauce added samples were significantly lower than the control(p<0.001). A positive trend was observed for color value with sancho added sauce(p<0.001). The another positive effects on the texture of fish was observed for texture analysis, adhesiveness, springiness, gumminess, and chewiness with herb sauce added samples(p<0.05). In the flavor profile, the fishy smell was disappeared and antifungal flavor was improved with herb added sauce. Flavor, taste, texture, and overall preference of herb sauce were significantly highest in sancho added sauce(p<0.05, p<0.001). Results suggest that the best herb sauce for roasted mackerel was sancho added sauce.
