the objective of this study was to develop the Korean style fermented sausage by addition of Korean native spices(Mugwort Artemisaia asiatica ;pine needles pinus thunbergii ; Japanese pepper Zanth-oxylum prperitum ; Arrowroot pueraria hirsuta) instead of foreign-original spices(white pepper corian-der)pH of all sausages was lowered rapidly during ripening. pH reductio of sausages with foreign spices was mere rapid than that with Korean native spices except for the sausages with all mixtured Korean native spices. Aw was not affected by differentiated spices. The "a" value among Hunter Color Value of sausages that produced with mixed Korean native spices was higher than sausages with foreign spices Lactic acid bacteria rapidly increased and reached to 108cfu/g after 2 days of ripening. Korean native spices used to this work did not inhibit the inhibit of lactic acid bacteria in fermented sausages but enterobacteria did not detected after 10 days of fermentation in the sausages with mixed Korean native spices.

A comparison of intake, digestibility and nitrogen balance in spotted deer(Cervus nippon) fed forest by-product silage(FBS), arrowroot silage(ARS) and oak leaf hay(OLH) was made to examine the feeding value of forest by-product silage. Dry matter digestibility of ARS was significantly higher(p$<$0.05) than that of OLH while crude protein digestibility was significantly higher(p$<$0.05) in ARS and FBS than in OLH. The digestibility of crude fiber was highest in FBS. Dry matter intake of OLH was significantly higher(p$<$0.05) than that of ARS, and there was no significant difference with FBS. Nitrogen intake was higher in OLH and ARS than in FBS, but there was no significant difference. Fecal nitrogen was highest(p$<$0.05) in OLH and urinary nitrogen was highest(p$<$0.05) in ARS. Retained nitrogen was highest in FBS, however, there was no significant difference among treatments. In Conclusion. FBS was estimated as a useful roughage source for deer, showing high digestibility, dry matter intake and nitrogen utilization.

In our study, osteoporosis was induced by ovariectomized in female Sprague-Daweley (SD) rats, and the prevention and treatment efficacy of the climacteric disease the ostmenopausal type I pattern was examined by using the experimental substance soybeans and arowroot. No clinical signs and mortality after continuous oral administration of experimental substances for 14 weeks were not observed, however, the weight of experimental animals underwent ovariectomized was increased significantly in comparison with control group (p<0.01). The atrophy of the uterus due to T3 group was 23.64% after 7 weeks, 24.44% after 14 weeks (in comparison with N.C. group), and it was statistically significantly increased. In regard to the change of blood cells, it was observed that platelets were statistically significantly reduced in the ovariectomized group, and administered orally experimental substances continuously for 7 weeks, in all groups administered experimental substances, it was found that platelets had the tendency to be increased more than N. C. group. In regard to He change of blood biochemistry, removed the ovary, the concentration of ALP showed the tendency to be increased than control group, and particularly in T3 group, it was increased significantly. In regard to the concentration of cholesterol, in comparison with negative control group, it was reduced 68% at 7 weeks and 35% at 14 weeks. After ovariectomized, the amount of estrogen was found to be reduced by 21.37% in comparison with control group, it showed the tendency to be increased by 4.49% in T1 group and 7.62% in T2 group, the concentration of estrogen in each group showed the tendency to be increased than negative control group, and in T3 group, it was increased to 100.46% and 117.65% in T4 group, and it was increased more than control group. Based on the above experimental results, in the experimental animals female rats, because of the hormonal imbalance induced by ovariectomized, a large mount of fat is accumulated in the body and due to it osteoporosis, obesity, hypertension, hyperlipidemia, fat of the liver, arteriosclerosis, diabetes, and other metabolic diseases were developed. Hence, when the experimental substance Extraction of ferment arrowroot was orally administered continuously for 14 weeks, it was thought that a certain proportion of the hormonal balance was maintained that functioned as a substance interfering the accumulation of fat, and it was considered to be of help in the treatment of not only osteoporosis Type I, but also for the prevention and treatment of various endocrinal diseases.

The phenolic substances contents of 45 plant foods in Korean diet were determined by different methods. Total phenolics contents by Folin-Denis method were $0.1{\sim}5.8%$ (dry matter basis), in which persimmon leaf, chestnut's inner skin, Chinese quince, walnut, sunflower seed and arrowroot exhibited the higher levels above 2%. Condensed tannin contents by vanillin method were $0{\sim}48%$, in which Chinese quince and chestnut's inner layer gave very high levels. Protein-precipitable phenolic substances ranged from 0.4% to 2.2%, in which chestnut's inner layer, walnut and Chinese quince had the highest content. The ability of phenolics to form precipitate was higher with pepsin and albumin than with trypsin. Among different phenolics content, total phenlolics correlated significantly with protein-precipitable phenolics (r=0.65) and condensed tannin (r=0.56). Chinese quince, chestnut's inner skin and sorghum showed a relatively lower degree of polymerization, as expressed by vanillin/FolinDenis ratio. Processed foods from buckwheat, acorn, mugwort and arrowroot showed a lower content of phenolic substances, suggesting a negligible adverse effect on the bioavailability of food proteins, if any.

In several leguminous plants such as acasia, arrowroot and bushclover, growth rate and contents of nitrogen, phosphorus and potassium in the tissues and the variation in the culture media were determined. In water cultrue which was free of added nutrients, nitrogen was found to be largely in the form of nitrate(NO3-N). This NO3-N is believed to be the result of nitrification from NH4-N which was apparently released form the plants. From the studies of organ culture with root segments, the amount of nitrogen released and absorbed was found to be proportional to the amount added to the mediuim. Especially, in the N-plot, the amount of nitrogen absorbed by the tissue reached more than 90% of the amount supplied to the medium already in early stage. On the contrary, in the amount free plot, the amount of nitrogen released from the tissue was lower than the minimum level in the N-plot. The amount of total N and P in the cultured tissue was found to be influenced by the amount of nitrogen addedin the medium. However, the amount of K in the tissue was not related to the nitrogen level in the medium, but rather it was influenced by the amount of added potassium. These findings present little difference in the metabolic pattern among the three species plants studied, and suggest that the woody leguminous plants have some common features in tehir metabolic pattern.

Objectives : Many curative methods are used utilized in order to rid human body of disease when people become sick. Traditional Korean medicine generally prescribe methods that involve acupunture, moxibustion, or herb formulae. However, different types of foods are sometimes used as well. While wondering the history and efficacy of Qi-elevation foods that were consumed by Koreans in the past, the author discovered that a record from the Joseon Dynasty, called The Daily Record of Royal Secretariat of Joseon Dynasty, henceforth the Records, contained information about different types of porridge. Hence, the author looked through the records of porridge as written in the historical material in an attempt to learn the examples and efficacy of medicine-porridge consumed in Joseon's royal palace. Methods : After searching for the keyword, 'porridge', in the Records as provided by the National Institute of Korean History, the author extracted the porridges recorded during the Yeongjo period that each has its own special name. Results : Different types of porridge were recorded in the Records as following: arrowroot porridge, bean-leaf porridge, mung bean porridge, bean porridge, malt-rice porridge, oriental arborvitae seed porridge, crucian porridge, lotus seed porridge, adlay porridge, red bean porridge, welsh onion porridge, milk porridge, seashell porridge, ginko nut porridge, black sesame porridge, and mandarin porridge. Each porridge was used for the purpose of alleviating any disease that afflicted the king Yeongjo or his royal family members in relation with the ingredient herb's medicinal function. Conclusions : These porridges consumed by the king Yeongjo and his royal family members were used not only with a purpose of aiding their body's recovery from disease, but with the goal to actively curing them of ailments.

In order to increase the antioxidant effect and preference of jujube-omija herbal sauce, we added ethanol extracts of 12 kinds of food and 12 kinds of medicinal herb to the sauce, and then evaluated the antioxidant activity and sensory characteristics. The antioxidant activity of the jujube-omija herbal sauces was greatly increased by the addition of ethanol extracts of foods such as green tea, mugwort, mint, lemon, leek, etc. and those of medicinal herbs such as ginseng. pine needle, the root of arrowroot, orange peel, etc.. Due to the high content of phenolic compounds, the ethanol extracts foods and medicinal herbs appeared to be responsible for high electron-donating ability and low hydroperoxide productivity. While the jujube-omija sauce with the extracts of green tea, mugwort, ginseng and pine needle were not preferred by the panels due to bitter taste and aroma, those of lemon, fruit of Chinese quince, orange peel, etc. were preferred with their sweet and a little sour taste and showed a high antioxidant activity. Especially, lemon juice was the best to increase the antioxidant activity and the preference of the jujube-omija herbal sauce.

Acetone powder was prepared from raw arrowroots and the polyphenol oxidases of crude enzyme prepared from acetone powder were identified 5 isoenzymes by staining with catechol containing 0.05% phenylene diamine. The crude enzyme was passed through the columns of ion exchangers and gel permeation to fractionate the polyphenol oxidases. The main fraction of polyphenol oxidase appeared to be purified by 94-fold, with the activity yield of 45.4%, and its molecular weight was determined as 38,500 by poly acrylamide gel electrophoresis. The optimal pH and temperature for the enzyme activity were pH 7.5 and $50^{\circ}C$, respectively. The purified enzyme showed a high affinity for catechol and pyrogallol. The Michaelis constant for catechol was calculated to be 16.67mM according to the Lineweaver-Burk method. The enzyme activity was strongly inhibited by L-ascorbic acid, sodium bisulfite, EDTA and KCN, and totally inhibited, by $Fe^{3+}$ at a concentration of 1mM. However the enzyme was activated by $Zn^{2+}$ approximately 1.7 times at the same concentration.
