The primary objective of this study was to develop an optimal composite recipe for ginger extract candy with Salicornia herbacea L., for consumption during the first trimester of pregnancy. The secondary objective was to examine quality characteristics of the candy. The physical and mechanical properties and sensory properties for pregnant women in were measured, and these values were applied to mathematical models. Time of stirring water solution, saltiness, pH, and redness of the candy increased as concentrations of ginger juice did, but variations in pH were not significant. The hardness values of the candy ranged from 3,063.90 to $5,681.65dyne/cm^3$. The average values of sweetness and time stirring the water solution were 5.36% and 14.1 minutes, respectively. However, hardness and sweetness stirring water solution were not significant. The range of sensory values of color (P<0.01), flavor (P<0.05), sweetness, saltiness, spiciness, and overall quality (P<0.05) ranged from were 3.73~5.32, 4.05~5.05, 3.67~5.14, 3.59~5.09, 3.55~5.15, and 3.32~5.45, respectively. Results suggest that ginger extract candy with Salicornia herbacea L. should be comprised of 7.37 g of ginger juice and 1.77 g of salt. Consequently, it could be a functional candy for pregnant women.

The principal objective of this study was to develop and standardize a preparation method for low-sodium tomato jangachi (traditional Korean pickle) via short-term fermentation with immature green cherry tomatoes. In order to determine the preferred concentrations of soy sauce and soaking temperatures of immature cherry tomato pickles in different stages of storage, we conducted an analysis of physico-chemical characteristics and microbiological properties, and also performed a preference test on samples of immature green cherry tomato pickles. Immature cherry tomatoes were prepared in three different soy sauce concentrations --20, 40, and 60%-- and three different soaking temperatures --60, 80, and 100$^{\circ}C$-- and then stored for 28 days at 5$^{\circ}C$. As a result, the pH increased significantly with increases in the amount of soy in the dipping solution (p<0.05). The saltiness was maintained at levels of approximately $0.17{\sim}0.28%$ (20% group), $0.32{\sim}0.67%$% (40%group), $0.48{\sim}1.00%$ (60% group) during storage periods. These results show that the saltiness of immature cherry tomato pickles was substantially lower than that of commercial pickles. The contents of reducing sugar and lightness decreased significantly with increasing concentrations of soy dipping solution. The redness and yellowness values of the tomatoes decreased significantly with increasing concentrations of soy sauce. Additionally, the lower the concentration of soy sauce used, the more rapidly the hardness of the immature cherry tomato pickles was reduced at 100$^{\circ}C$. PME activity moved within a narrow range, and then stabilized during the storage period. With regard to the results of the consumer preference test, 20%-100$^{\circ}C$ was the most preferred condition overall, 40%-80$^{\circ}C$ was the condition in which the texture was most preferred, and 40%-80$^{\circ}C$ was the condition that yielded the highest color scores.

The common KIMI-Theory of Oriental medicine has evaluated clinical effects of herbal-drug based on KI, nature of berbs, and tastes. The KI in the theory consists of hotness, warm, cool and coldnes and also the Mi does five tastes such as sour, bitterness, sweet, spicy hotness and saltiness. However the KI does not mean thermal effect only. Thus we tried to determine skin and rectal temperatures at the same time for evaluating the relationship between KI and berbs. Male, adult Sprage-Dawly rat was chosen and berbal extract, 10g/Kg, was given orally once at 9:00 A.M. changes in rectal and skin temperatures were measured at 10, 30, 60, and 90 mins after the drug administratin. The changes in body temperatures are in greate deal of agreement of KI written in Herbology literatures.

The purpose of this study was to analyze the patient's satisfaction on hospital foods according to their age. The subjects were selected among the patients treated in the Eulgi University hospital during May of 2003. Two hundred twenty one patients (110 men, 101 women) were surveyed through questionnaires in terms of satisfaction on hospital foods and the food preference. The data were statistically analysed using $\chi$$^2$-test and their correlation. Satisfaction on general taste(p<0.05) and variety of hospital foods (p<0.05) were significantly different according to age. However, saltiness and serving temperature of hospital foods were significantly different according to sex(p<0.05). The preference of cooking method for meat, fist vegetable and the preferred kinds of Kimchi(p<0.05) and milk & milk products(p<0.05) were significantly different according to age.

The whole saltwort plant (Salicornia herbacea) was micronized to develop the table salt substitute. The micronized powder was mixed with distilled water and made into a spherical granule by using the fluid-bed coater (SGMPDW). The SGMPDW had superior flowability to powder; however, it had low dispersibility. To increase the dispersibility of SGMPDW, the micronized powder was mixed with the solution, which contained various soluble solid contents of saltwort aqueous extract (SAE), and made into a spherical granule (SGMPSAE). The SGMPSAE prepared with the higher percentages of solid content of SAE showed improved dispersibility in water and an increase in salty taste. The SGMPSAE prepared with 10% SAE was shown to possess the best physicochemical properties and its relative saltiness compared to NaCl (0.39). In conclusion, SGMPSAEs can be used as a table salt substitute and a functional food material with enhanced absorptivity and convenience.

This study was conducted to investigate the effect of fresh ginseng on the physicochemical, microbiological and sensory properties of Nabak-kimchi during 33 day fermentation. Nabak-kimchi with the various levels (0, 2, 4, 6％) of fresh ginseng were fermented at 4$^{\circ}C$. During the fermentation, pH was lowered in all Nabak-kimchi samples and pH of Nabak-kimchi added fresh ginseng was a little lower than that of Nabak-kimchi without fresh ginseng. Acidity increased continuously during the entire fermentation. Saltiness was maintained at 1.60-1.67% levels during the whole fermentation. Total vitamin C contents increased drastically on the first day of fermentation and decreased after the first day and then increased during 21-24 day fermentation. Total bacteria increased rapidly at the beginning of fermentation and reached its maximum number on 6th day offermentation and then decreased slowly. Total bacteria of Nabak-kimchi added fresh ginseng was highly main-tained during the entire fermentation periods. As a result of the sensory evaluation, Nabak-kimchi added 4% fresh ginseng was the most palatable one.

It was the purpose of this study to determine if the changes in the sense of taste occur with the periods of the menstrual cycle in 14 women aged 20 to 22 years. Results showed that the perceived intensity responses to different suprathreshold salt concentrations and the ad libitum salting level in soybean sprout soup did not differ significantly according to the different periods of the menstrual cycle. But women in the three or five days period previous to menstruation were sensi\ulcornertive at the lower salt concentration of 0.25%, but, on the contrary, were insensitive at the higher concentration of 1.25%, with increasing ad libitum salt preference in soybean sprout soup. Also, they were more or less high in the intensity slopes of perceived saltiness on the linear regression. The data suggests that a physiological mechanism for increasing salt intake may develop during the three or five days right before menstruation.

pH, proximate analysis and functional properties were not significantly affected by reduced salt levels in NFS which contained 75${\sim}$76% moisture, 14${\sim}$15% protein < 0.5% fat in the final products. However, NFSs had differences in color and EM (%) values as compared to RFS, The results of textural test showed that they were not different with reduced salt levels (0.75${\sim}$1.5%) among the RFS and no-fat treatments (P>0.05). NFS containing 1.0% salt had similar sensory color, flavor and saltiness values to those RFS. These results indicated that NFSs was successfully manufactured with 1.0% salt level and these may contribute to the 'healthier meat products' for consumers due to no-fat and low-salt meat products.

The effect of chitosan on physicochemical and organoleptic properties of Nabak kimchi was studied during fermentation at 2$0^{\circ}C$ . Viscosity of the juice of Nabak kimchi added with chitosan was lower than that of control group. The viscosity was gradually increased during storage period, especially from 5 days to ,7 days of storage. Initial pH was higher in control group than inchitosan groups. The pH of controlgroup decreased rapidly during 4 days of storage. The pH of chitosan groups was slightly increased during the first 3 days of storage and decreased thereafter. Acidity was rapidly increased from 3 to 5 days. Reducing sugar contents increased up to 3 days and decreased thereafter. Acidity was rapidly increased from 3 to 5 days. Reducing sugar contents increased upto 3 days and decreased therafter. Glutamic acid, alanine, threonine, aspartic acid, proline and valine were the major free amino acids, and as the fermentation preceeded they were increased gradually. There were signigicant differences in saltiness, sourness and aged odor in sensory evaluation of Nabak kimchi solution during fermentation at 2$0^{\circ}C$.

In recent decades, health concerns related to sodium intake have caused an increased demand for salt or sodium-reduced foods. Umami substance can enhance taste sensitivity to NaCl and may offer a unique approach to replace and reduce the sodium content in foods. In this study, hot water extraction conditions of Wando sea tangle with high umami taste were investigated. Wando sea tangle harvested in June was selected for hot water extraction based on its free amino acids composition. The quality properties of sea tangle extract were investigated at various extraction temperatures ($60^{\circ}C$, $80^{\circ}C$, and $100^{\circ}C$) and times (1 h, 2 h, and 3 h). Sea tangle extracts at the extraction temperature of $100^{\circ}C$ contained the highest soluble solids (35.47%~36.93%), and crude protein (3.75%~4.00%). Viscosities of sea tangle extracts decreased with increasing extraction temperature. Umami amino acids (glutamic acid and aspartic acid) and sensory characteristics were best at extraction conditions of $100^{\circ}C$ for 2 h. Saltiness enhancement of sea tangle extract powder was determined. Saltiness intensities of NaCl solution after adding 1% sea tangle extract powder were enhanced (1.84~4.25-fold). At the same saltiness intensity, sodium contents of NaCl solution with 1% sea tangle extract powder were 12.24~24.33% lower than that of NaCl solution. These results suggest that it is possible to reduce sodium in foods with sea tangle extract as a natural salt enhancer without lowering overall taste intensity.
