This study was done to evaluate the effects of grape variety, pH and sugar contents on textural and sensory properties of grape pectin jelly. As a gelling agent, pectin 1% was selected due to highest sensory scores in preparatory experiments and also nutritional and economical reasons. To get the proximate composition of grape extract, moisture, pH, reducing sugar, and total titratable acidity was measured. Grape pectin jellies, made by 12 different recipies, were tested by sensory and instrumental evaluatoin. The results were as follows; 1) Hardness and chewiness were lowered in grape jelly which has lower pH and lower sugar contents. 2) People preferred grape jelly which has lower hardness, brittleness and sweetness, and higher sourness. 3) Comparing overall quality, Recipe C1 in Jelly 1 and recipe B1 in Jelly 2 were chosen as best. 4) Sensory hardness showed positive correlation with instrumental hardness, brittleness and chewiness.

In the present study, the proximate composition, sugar, minerals, total phenolic and flavonoid compounds, and amino acids in Calystegia japonica (C. japonica) were measured to determine if it can be used as a nutritional and functional material for the development of valuable foods. The mean crude protein, fat, and ash contents of the leaves were 5.75, 2.46, and 7.77%, respectively. The soluble-protein contents of the leaves and roots were 146.78 and 33.67 mg%, respectively. The reducing-sugar and free-sugar contents of the leaves were 682.70 and 166.00 mg%, respectively, and those of the roots were 2,934.89 and 37.70 mg%. The mineral content of the leaves was 3,122.13 mg%, and that of the roots was 1,540.85 mg%. The three elements Ca, K, and Mg were very rich in all their parts, with minerals accounting for 96-99% of their total mineral contents. The total phenolic compound of the leaves was 3,028.89 mg%, and the total flavonoid compound was 382.67 mg%. The phenolic and flavonoid compounds in the leaves were more than 7.6 times those in the roots. The free-amino acid levels in the leaves and roots were 2,467.15 and 1,334.81 mg%, respectively. The results of the comparison of the leaves and roots of C. japonica showed that the leaves had a rich proximate composition consisting of minerals, total phenolic and flavonoid compounds, and amino acid. This suggests that C. japonica leaves are potentially useful sources of functional and favorite foods and nutraceuticals.

The concentrations of functional compounds and micronutrients of chicken breast from native chickens were compared with those from broiler. Totally 200 male chicks from a commercial native chicken (HH) and three newly bred native chicken strains (2A, 2C, and 2D) were reared for about 2 kg of final live weight up to 12 wk. After slaughtered, antioxidant dipeptides, reducing sugar, free amino acids, vitamins, and minerals of the breast muscles were analyzed with those from broilers with similar live weight. Mostly native chicken strains had higher contents of carnosine, anserine, and reducing sugar than the broiler. Especially HH implied the highest values of carnosine and anserine, and 2C did the highest of reducing sugar (p<0.05). Vitamin A contents between native chickens and broiler were not significantly different (p>0.05). The contents of ${\alpha}-tocopherol$ were significantly higher in 2C than those of HH or broiler (p<0.05). Native chicken strains contained lower cholesterol levels than the broiler. Broiler had higher contents of P, Mg, and Na than native chickens (p<0.05), but it had lower content of Cu than HH or 2A. The savory free amino acids including glutamic acid was highest in 2A than the other native chickens and broiler (p<0.05). This study confirms that certain new strains of native chickens be a good source in terms of functional compounds and micronutrients which can be attractive health promoting nutritional quality factors.

The existing fruit sorter has the method of tilting tray and extracting fruits by the action of solenoid or springs. In peaches, the most sort processing is supported by man because the sorter make fatal damage to peaches. In order to sustain commodity and quality of peach non-destructive, non-contact and real time based sorter was needed. This study was performed to develop peach sorter using near-infrared spectroscopy in real time and nondestructively. The prototype was developed to decrease internal and external damage of peach caused by the sorter, which had a way of extracting tray with it. To decrease positioning error of measuring sugar contents in peaches, fiber optic with two direction diverged was developed and attached to the prototype. The program for sorting and operating the prototype was developed using visual basic 6.0 language to measure several quality index such as chlorophyll, some defect, sugar contents. The all sorting result was saved to return farmers for being index of good quality production. Using the prototype, program and MLR(multiple linear regression) model, it was possible to estimate sugar content of peaches with the determination coefficient of 0.71 and SEC of 0.42bx using 16 wavelengths. The developed MLR model had determination coefficient of 0.69, and SEP of 0.49bx, it was better result than single point measurement of 1999's. The peach sweetness grading system based on NIR reflectance method, which consists of photodiode-array sensor, quartz-halogen lamp and fiber optic diverged two bundles for transmitting the light and detecting the reflected light, was developed and evaluated. It was possible to predict the soluble solid contents of peaches in real time and nondestructively using the system which had the accuracy of 91 percentage and the capacity of 7,200 peaches per an hour for grading 2 classes by sugar contents. Draining is one of important factors for production peaches having good qualities. The reason why one farm's product belows others could be estimated for bad draining, over-much nitrogen fertilizer, soil characteristics, etc. After this, the report saved by the peach grading system will have to be good materials to farmers for production high quality peaches. They could share the result or compare with others and diagnose their cultural practice.

KA 101 and Xanthi-Basma were cultivated in Korea and Greece to compare the respective responses to environments on their leaf composition during 1984 and 1985. Cured leaves cultivated in Greece had brighter and greenish color with 2-4 times higher total chlorophyll and carotenoids showing higher contents of total nitrogen, nicotine, petroleum ether extract, volatile acids and neutrals, but crude ash and pH of leaves at top stalk position were lower than in Korean cultured leaves. Xanthi-Basma showed higher contents of nicotine and total nitrogen, but lower contents of reducing sugar than KA 101. There were no difference in crude ash, petroleum ether extract contents and pH of leaves. Among stalk positions, the upper stalk leaves in Greece had higher contents of total nitrogen, protein nitrogen, nicotine, petroleum ether extract and volatile acids but lower contents of reducing sugar than lower ones., whereas the supper stalk leaves in Korea had much higher contents of total nitrogen, protein nitrogen, pH, crude ash, but not higher contents of petroleum ether extract and volatile acid contents than lower stalk position. It suggest that in chemical criteria the better quality leaves are on the upper stalk position in Greece but not the same in Korea probably due to the rainy weather conditions during the later growth stage in Korea.

Objectives : This study was performed to compare the differences between decoctions extracted by different extraction conditions. Methods : Two different decoctions were prepared with pressured or non-pressured extraction conditions for 60, 120 and 180min. The yields of extracts, sugar contents, hydrogen ion concentrations(pH), the contents of reference compounds and individual preferences on Ssanghwa-tang(Shuanghe-tang) were investigated. Results : As extraction time increased, individual preferences for decoctions by pressured extraction tended to increase more than those by non-pressured extraction, and the yields and sugar contents of both decoctions showed the tendency of increase. The pH values of decoctions in pressured conditions were lower than those in non-pressured conditions in all extraction times and both extraction conditions showed decreasing pH values according to increase of extraction times. Of the reference compounds, paeoniflorin showed higher contents in non-pressured conditions than in pressured conditions and the contents of cinnamaldehyde were always lower in non-pressured conditions than in pressured conditions at all time. Conclusions : The decoctions of Ssanghwa-tang(Shuanghe-tang) extracted by pressured or non-pressured extraction for 60, 120, 180min exhibited different individual preferences, yields of extracts, sugar contents, pH, reference compounds contents.
