This study was conducted to determine grazing intensity of growing Korean native goats(Capra hircus coreanae) on mountainous pasture. It was carried out to obtain basic information for improvement of mountainous pasture management and establishing feeding system of Korean native goat. A total of 20 goats were grouped by feeding systems [A mountainous pasture grazing group (Concentrated feed of 1.5% body weight, treatment 1, T1, n=10) and a barn feeding group (TMR, treatment 2, T2), n=10] to conduct study from April to September. The average forage productivity of the mountain pasture was 500.9 ± 61.41 kg/ha. The average dry matter intake in T1 was 0.64 and the calculated grazing intensity was 21 head/ha. In productivity, when the two treatments(T1, T2) were compared, the dry matter intake was about two to three times the difference. The average daily gain per day during the experiment was 63.3 in the mountain pasture and 120 g in barn feeding. When grazing, considering mountainous pasture productivity it is necessary to increase the productivity through proper feeding. The feed costs of black goats raised by grazing on the grassland in the same period showed an average 75% reduction compared to barn feeding. As a result of this study, it can be expected that a considerable reduction of feed costs can be expected in the breeding of Korean native black goat using the mountain pasture.

The quality characteristics of Acanthopanax and Cedrela shoots during their preservation were investigated according to the salting conditions to improve the use of the shoots. The results were as follows: The pH of added ionization mineral during the storage did not change. The salinity of the salt-stored Acanthopanax and Cedrela tended to insignificantly change as their storage temperature changed and increase during the addition of the ionization mineral. In terms of the color values, the b value of the added non-ionization mineral tended to increase and that of the added ionization mineral tended to gradually decrease. The texture of Acanthopanax and Cedrela shoots to which an ionization mineral was added tended to decrease gradually during their storage, and was highest when 50 ppm of the ionization mineral was added. The total chlorophyll contents tended to decrease during the salt storage, did not change significantly with the change in the added ionization mineral, and decreased at the storage temperature of 10℃. Therefore, it can be concluded that quality of Acanthopanax and Cedrela shoots can be maintained when they are stored in ionization mineral addition.

The quality characteristics of kalopanax pictus and Aralica elata shoots during their preservation were investigated according to the salt conditions and storage temperatures to improve the use of the shoots. The results were as follows: the pH of kalopanax pictus shoots duing their storage did not changes with 10% and 12% brine at 4℃ and with 12% brine at 10℃. The pH of Aralica elata shoots is at 4℃ tended to be similar to the kalopanax pictus shoot and decreased at the storage temperature of 10℃. The salinity of the kalopanax pictus and Aralica elata shoots tended to increase during their storage and did not change significantly as their storage temperature changed. The L values of kalopanax pictus and Aralica elata shoots tended to decrease gradually during their storage, and the salt concentrations appeared high. The b value of the kalopanax pictus shoot tended to increase and that of the Aralica elata shoots, to decrease gradually. The a value tended to increase gradually but did not differ with variations in the storage temperatures and salt concentrations. The strength and the hardness of the kalopanax pictus and Aralica elata shoots tended to decreased gradually during their storage and highest in 10% brine at 4℃, and those of Aralica elata shoots were highest in 8-10% brine at 4℃. The Chlorophyll contents of the kalopanax pictus and Aralica elata shoots tended to decrease during their salt storage and did not change significantly as the temperatures and salt concentrations changed. Therefore, it can be concluded that the quality of kalopanax pictus and Aralica elata shoots can be maintained when the are stored in 10% brine at 4℃.

The characteristics of the narirutin-added alcohol fermentation of citrus hydrolysates were investigated to produce functionally improved citrus wine. The pH of narirutin-added citrus wine ranged from 3.38 to 3.51, and the titratable acidity was about 0.55% which show no significant differences attributable to the narirutin quantity. With regard to the color and brown color, with the addition of more narirutin, the a value was decreased while the b value and brown color increased. The sugar content decreased from 24 to 8.0-8.5 ˚Brix after alcohol fermentation, and the alcohol content appeared to be between 14.5 and 14.6% in all the sections. For the free sugar contents, the glucose and fructose contents were relatively high in every section. For the total polyphenol content, it was shown to increase when more narirutin was added. and the 2%-narirutin-added section showed the highest polyphenol content(46.44 mg%). The results of sensory evaluation were that the color, flavor and bitterness increased while the sweetness and overall acceptability were reduced by the additional narirutin. Functionally improved citrus wine can be produced by using narirutin, but more researches regarding quality improvement should be carried out to overcome the bitterness.
