  • To increase the added value of peaches and utilize overproduced peaches, it is necessary to develop peach raw materials in various forms. In this study, usefulness of juice as raw material for vinegar was investigated by comparing and analyzing the characteristics of the traditional fermented vinegar prepared with 4 types of juice (fresh, refrigerated, boiled and frozen puree). Sugar content (6.20~6.50°Brix), total acidity (5.25~5.61%), pH (3.42~3.74), and acetic acid content (48.81~54.29 mg/mL) of the vinegar were all similar to existing traditional fermented vinegar. However, contents of total phenol and flavonoid were higher in vinegar prepared from refrigerated and boiled juice. Therefore, it was confirmed that boiled and refrigerated juice are very suitable as raw materials for traditional fermented peach vinegar, in particular, it was confirmed that boiled juice with a high content of total phenol and flavonoid can be used as a high value-added functional material. These results are considered to be important guidelines for developing high value-added raw materials for peaches.

  • It was attempted to observe the effect of garlic on the hepatic purine metabolizing enzymes in this study. The activities of adenosine deaminase, guanase, and uricase in rats were not changed significantly following the feeding of 5% garlic juice. Whereas, garlic juice inhibited significantly the hepatic xanthine oxidase activity compared to control group with the lapse of treated-period. The orate level of serum in rats was significantly decreased by the treatment of garlic juice. The above inhibitory effect of garlic was greater in boiled garlic juice than fresh garlic juice-treated group. These results indicated that, according to the chemical properties of allicin which is unstable in heat, other components than allicin in garlic may regulate the hepatic purine metabolizing enzymes.

  • Oysters, especially are excellent source of several mineral including iron, zinc and selenium, which are often low in the mordern diet. They are also an excellent source of glycogen, vitamin B12 and considered the healthiest when eaten raw on the half shell in good tasted season from November to March. This study was investigated for the purpose of obtaining basic data which can be applied to processing of two kinds of canned boiled oyster (canned boiled oyster, canned boiled oyster in bamboo salt). Shucked oyster meat was cooked in steam (15min) after washing with water, filled 90g into can (301-3), added with salt solution and then precooked for 10 min. at $100^{\circ}C$. Canned boiled oyster was added 1.5% salt solution 60mL. Canned boiled oyster in bamboo salt was added 0.5% salt solution 30mL and 0.7% bamboo salt solution 30mL. The cans were seamed using a vacuum seamer, and then sterilized for various Fo values (Fo 8~12 min.) in a steam system retort at $116^{\circ}C$, $118^{\circ}C$. Viable bacterial count, proximate composition, pH, salinity, yield, VBN, amino-N, TBA, mineral, color value, free amino acid, hardness and sensory evaluation of two kinds of canned boiled oyster produced at various sterilization condition (Fo 8~12 min.) were measured after divide to meat and juice. The results showed that canned boiled oyster in bamboo salt sterilized at Fo 8 min. was the most desirable because this condition is the most economical and tasty.

For the food ingredients used in bap types 23 types of miscellaneous grains, 5 types of nuts and 11 types of meat, 6 types of fish, 35 types of vegetables, 2 types of fruit including pears or peaches were used. Garlic wasn't used perhaps because of it being boiled rice 3. Types of Sap by Cooking Methods. (1) The ssalbap was cooked by first boiling water, putting in rice grains and boiling hard to be cooked as overcooked bap (rice). (2) The japgokbap (boiled cereals) has used buckwheat, barley job's tear, etc to be boiled down by soaking the ones with large grains (beans) first in advance to be boiled down or cooked by crushing into fine pieces. The red bean, etc was boiled down in advance or placed at the bottom of pot by cutting into two pieces while jujube or nut was cut into three pieces to cook the bap by pouring a lot of water and mixing other ingredients. (3) The gukbap (soup boiled rice), etc were cooked by squeezing out the yellow chrysanthemum that has dried chrysanthemum to cook the boiled rice by putting in rice and gukbap, meat or bones, etc were boiled down for a long time and decorated with meat or wild greens by mixing the bap in the meat juice. For gulbap (oyster boiled rice), etc, it was cooked as ingredients were stir fried in advance or washed and put in when the bap was about half cooked. (4) For bibimbap (mixed boiled rice), after the bap was overcooked first with rice, the wild greens were mixed lightly with bap beforehand, then the wild greens, decorations and garnishings were laid above rice and red pepper powder was sprinkled. (5) Namchok leaves, etc were boiled to cook the boiled rice with rice after being cooled while namchok stem and leaves were pounded to make juice and cooked the bap with rice. The peach, lotus root and yams were cut into fine pieces to be put in together when rice was about half done.

  • This study was carried out to investigate some antioxidative effects of stewed pumpkin juice (SPJ) and the SPJs added with ginger (SPJ-G), onion (SPJ-O), jujube (SPJ-J) or boxthorn (SPJ-B), respectively, on the lipid oxidation of soybean oil (S) and mackerel pike boiled ground (MPBG). Antioxidative substances of SPJ were extracted by using the two solvent layers of n-hexane:acetone (1:1)(H) and methanol:water (7:3)M. The antioxidative effects of the extracts were observed by the peroxide value (P.O.V.) and thiobabituric acid (T.B.A.) value. The P.O.V. and T.B.A. value of two solvent extracts of S and MPBG showed significantly lower than those of S and MPBG. The SPJ showed very distingnished antioxidative effects. It was considered that melanoidine extracted by using methanol:water (7:3) solvent as well as carotenoid extracted by using n-hexane:acetone (1:1) solvent had an antioxidative effect. During storage, T.B.A. value of MPBG significantly increased, while that of MPBG-SPJ significantly decreased more than that of MPBG. T.B.A. value of MPBG-SPJs decreased much than that of MPBG-SPJ, SPJ-O, SPJ-G, SPJ-J and SPJ-B, in order of abundance, showed higher level of antioxidative effects than SPJ.

  • The aim of this study was to evaluate proteolytic and antioxidant activities of fresh pineapple and kiwi juices extracted using a slow-speed masticating household juicer during low temperature storage. While over 90% of vitamin C and total polyphenols in both juices were retained after storage for 30 days at $-20^{\circ}C$, reduction of 56.8% for vitamin C and 31.9% for total polyphenols in pineapple juice were detected after storage at $4^{\circ}C$. In the case of kiwi juice, 32.9% of vitamin C and 22.4% of total polyphenols were lost. A high initial content of vitamin C in kiwi juice resulted in a slower reduction rate than that for pineapple juice. A similar result was obtained for 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Proteolytic activities of both juices were maintained efficiently with less than 10% loss during storage for 30 days at $-20^{\circ}C$. Protease stability of pineapple juice was better than that of kiwi juice during storage at $4^{\circ}C$, and the same result was obtained when boiled chicken breast was used as a substrate. From these results, when storing pineapple and kiwi juices, which are widely used as a natural meat tenderizer and digestive aid, cold storage at $-20^{\circ}C$ seemed to be more suitable for maintaining antioxidant and proteolytic activities than cold storage at $4^{\circ}C$.

  • The dried persimmon was effective in caring an inflammation, an ulcer and a burn and preventing hypertension and arteriosclerosis. At the Jejungsinpyun. dried persimmons gruel was beneficial to stomach and intestine and toned down voice. Based on Jejungsinpyuns and Sikryochanyo, dried persimmons gruel was developed for modern people. To standardize the dried persimmons gruel, physical properties and consumer acceptability was examined. The procedures of dried persimmons gruel was to make dried persimmons juice after soaking dried persimmons with same volume water during 24 hr and blending. To decrease the astringent taste of dried persimmons, dried persimmons juice and water with cinnamon (2%) was mixed and simmered during 3 min. Dried persimmons paste with cinnamon was added and the gruel was boiled more during 5 min. dried persimmons gruel was completed. The dried persimmons gruel were divided of 5 groups consisted of each 10, 15, 20, 25, 30 g dried persimmons. As dried persimmons content increased, lightness, apparent viscosity decreased. Acceptability test indicated the sample of dried persimmons : rice ratio at 2 : 5 had the highest overall acceptability and flavor. Considered to each, the sample of the dried persimmons : rice ratio at 2 : 5 met the purpose of the study.

  • This study designs to investigate effects of onion diet on carbon tetrachloride toxicity of rats. Experiments were performed with week's feeding, body weight, food intake, ratio of orgen weight/dody weight, serum lipid levels, superoxide dismutase and catalase activity and malondialdehyde(MDA) content in liver and kidney were determined. The content of serum total cholesterol in each group were lower than those of control group(p<0.05), especially at onion juice treated group. Serum HDL-cholesterol level of CBB and CBJ groups was significantly lower than that of control group (p<0.05). Superoxide dismutase activities of liver and kidney were significantly increased by carbon tetrachloride treatment and decreased by onion feeding. MDA contents in liver and kidney of CCl4 treated rats were significantly decreased by boiled and fresh onion fed group, compared with CCl4 treated control group. This result suggested that onion diet has a protective effect of CCl4 induced hepatotoxicity and nephrotoxicity of rat.

  • The amount of cellular components including soluble sugars, amino acids, organic acids and glucosinolates (GLS) was investigated during radish root processing to develop a radish beverage. The radish root was divided into two parts, white and green tissue, and processed separately by extracting the juice from the fresh tissue and from the boiled tissue to compare differences in the components content among the preparations. The overall palatability of both the fresh and boiled extracts from the green part of the radish was higher than that of the same extracts from the white part. The sweetness of extract by boiling increased and its pungency decreased, thereby the palatability increased by being compared to the fresh radish extract. The sweetness was affected by sucrose not by glucose or fructose of monosaccharides by showing different sucrose contents according to treatment comparing palatability. Malic acid was identified as primary organic acid, and the content was higher in both the fresh and boiled extracts from the white part than in the extracts from the green part of the radish. The fresh extract from the green part of the radish contained more essential amino acids, such as threonine and valine, and more hydrophilic amino acids including glutamic acid, aspartic acid, and arginine than those of the fresh extract from the white part, suggesting the green fresh part is more palatable than the white fresh part. The main sulfur compound was ethylthiocyanate in radish, and others were butyl isothiocyanate, dimethyl-disulfide, and 4-methylthio-3-butylisothiocyanate. The four GLS were detected much more in the fresh green and fresh white parts of the radish because they evaporated during boiling. The contents of the four sulfur compounds were higher in the white fresh part than in the green fresh part, which is likely the reason the pungency was higher and the palatability was lower in the white fresh part than in the green fresh part of the radish. The ascorbic acid content was higher in the fresh extract compared to the boiled extracts from both the green and white parts. Taken together, these findings indicate that fresh radish extract is superior to obtain in terms of retaining desirable nutritional and functional components for health.
