  • This study was investigated to find effects of soaking-water salt concentration and submaterial on Kimchi taste and fermentation period. several parameters such as pH, acidity, reducing sugar, amino acid and sensory evaluation during fermentation at 2$0^{\circ}C$ were experimented. The results are as follows : As fermentation period increases, pH and content of reducing sugar of Kimchi have decreased. But acidity has increased. Especially, the pH of all samples rapidly decreased to a extent of pH 4.2. During fermentation the acidity and content of reducing sugar in 12% soaking-water were higher than those in 16% and 20%. Content of reducing sugar I Kimchi was observed to play an important role for the overall taste. As a result of sensory evaluation during fermentation, Kimchi in 16%, 2.6% and in 20%, 3.7%. Sensory evaluation revealed that leek-added Kimchi was highly evaluated in crispness, sour taste, flavor and overall acceptability. These results suggested that Kimchi fermented for 4days at 2$0^{\circ}C$ with 16% salt concentration of soaking water and leek as submaterials should taste most desirable.

  • Recognition thresholds for NaCl, sucrose, citric acid, and caffeine, as well as the pleasant concentration of NaCl were assessed in 176 males and 312 females aged 50-88 years. Furthermore, relationships among taste sensitivities, taste preferences, and lifestyles were examined. The taste solutions were presented one after the other in ascending order using the sip-and-spit method. For the recognition thresholds of the 4 basic tastes, women perceived significantly lower concentrations than the men. However, the pleasant concentration of NaCl did not show a gender difference. Sensitivities for the 4 basic tastes did not decrease with age in the men, but they did significantly decrease with age for the women, especially for those above 70 years. For men, regular exercise was positively correlated with sensitivities for sour taste and bitter taste, and physical activity was negatively correlated with the pleasant concentrations of NaCl. For women, who had more physical activity, sensitivities for sweet taste and sour taste were lower compared to the others. This study indicates that the sensitivities for 4 basic tastes in water diminished with age, but pleasant salt concentration did not change with age. Further research on pleasant NaCl concentration is required to determine factors affecting salt preference, in order to decrease salt intake in the elderly.

  • The principal objective of this study was to determine the optimal mixing ratios of three different quantities of spirulina, salt and water for the preparation of Korean rice cake (Dukbokiduk) via response surface methodology on the basis of color, texture, and sensory test. The spirulina levels were tested in a range of $1{\sim}3%$, the water levels in a range of $15{\sim}25%$, and salt levels were tested a range of $0.5{\sim}1%$ by weight of rice powder. Taste was influenced most profoundly by the amount of added spirulina. Optimal taste was achieved with 1% of spirulina, 0.75% of salt and 20% water. Thus, the optimal mixing ratios of spirulina, salt, and water for Dukbokiduk were 1.0%, 0.57%, and 19.46%, respectively.

  • 본 연구는 코호트내 환자-대조군 연구설계를 통하여 0.5% 소금물에 대한 역치와 위암발생 위험의 관련성을 구명하고자 수행되었다. 강화 코호트와 강화 암등록사업을 통하여 얻은 위암 환자군 90명, 지역사회대조군 141명을 대상으로 수집된 자료를 분석한 결과 두군간에 건강관련 변수들의 분포에 별 차이가 없었다. 다만 '주관적 건강수준'과 '동년배에 비교한 주관적 건강수준'에 차이가 있었다. Cox외 비례위험모형을 이용하여 '주관적 건강수준' 흡연, BMI 등 혼란변수를 통제하고 추정한 '0.5% 소금물을 싱겁다'고 느낀 군의 '그렇지 않다'고 느낀 군에 비한 위암의 상대위험도는 0.77로 통계적으로 유의한 수준이 아니었다(표4). 앞으로 이 분야에 대한 연구는 소금섭취량 측정수준의 상향조정은 물론, 매운 음식 섭취의 감안과 이 두변수의 교호작용등을 고려하되 환자 본인에게서 자료를 얻을 수 있는 병원내에서 수행하는 환자-대조군 연구를 수행함이 바람직하다고 생각한다.

  • As a part of basic investigation for utilization of canned food processing by-products, a food components of the canned oyster processing waste water such as boiled and released water(BRW), wash water(WW) were investigated and compared with hot-water extracts from oyster. From the results of measuring heavy metal conte수, viable cells and coliform group, the canned oyster processing waste waters might not invoke health risk in using food resource. The contents of taste compounds (free amino acids, ATP related compounds, TMA (O) and total creatinine) of BRW and WW accounted for about 254% and 95%, respectively, in comparison with those of control (hot-water extract from oyster). The BRW showed a very high content of salt in comparing to the WW and control. In descending order, the values of whiteness index was WW, control and BRW. Sensory scores for color, oyster flavor intensity and saline taste were not significantly different between WW and control. But, BRW had the highest score in oyster flavor intensity, while had the lowest score in color and saline taste. But, the color and saline taste of BRW might be able to control by some pretreatment (concentration and drying in mild condition, desalination and recipe control etc). These results indicated that BRW and WW generated from various step during canned oyster processing could be a potential food resource by controlling of saline taste and color intensity.

  • The phyio-chemical properties of Ion exchange salt, crude salt, particaly refined salt, and Isoized salt were determined. The basic amount of salt used in cooking were standardized . Acceptabilities as to the taste and saltiness of food prepared with the standard amounts of various kinds of salt were compared. Whereupon, the following conclusion was obtained. 1) Crude salt showed 12.23 per cent water content, the highest among the kinds of salt examined, while particaly refined salt had 2.53% water content. Refined salt, Ion exchange salt, and Iodized salt showed 0.36%, and 0.28%, respectively. 2) Where the same amount of salt was dissolved in the same amount of water, crude salt and partialy refined salt were dissolved twice as Ion exchange salt of fine-grain form, refined salt, and Iodized salt. In actual cooking, Ion exchanges salt and refined salt are used only half as much as raw salt, and it can be said that the time required for dissolving salt is the same. 3) The comparison between content and weight of various kinds of salt showed that the weights of Ion exchange salt, Iodized salt, and refined salt were two times as heavy as crude salt and partialy refined condition of same content. 40 The threshold concentration of salt is the sensed degree of saltiness. Different concentrations were recorded for various for various kinds of salt, the threshold concentration of Ion exchanges salt showed the lowest degree of 0.05, while that of partialy refined salt was 0.09 equivalent to 1.8 times that of the former. 5) Experimental cooking involving various kinds of salt indicated that where salt was used accurately, soup, vegetables, kimchi, and soybean sauce which were prepared with Ion exchanges salt showed the best acceptability , but no statistical differences could be noted among sarious kinds of salt used in preparing those foods.

  • 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.

  • In order to establish the processing condition of rapid- and low salt-fermented liquefaction of anchovy (Engrulis japonica), effect of temperature on crude enzyme activity of anchovy viscera, pretreatment conditions, and the minimum content of adding NaCl were investigated. The minimum limitation of NaCl content for anchovy liquefaction was 10%. Sample A(water adding, heating, adding 10% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 10% NaCl and then fermented at room temperature$(8-29^{\circ}C)$ for 180 days. Sample B(water adding, heating, adding 13% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample C(adding 13% NaCl): chopped whole anchovy and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample D(adding 17% NaCl): whole anchovy adding 17% NaCl and then fermented at room temperature for 180 days. The content of free amino acids such as aspartic acid, serine and threonine fluctuated severely according to the pretreatment methods. Possibly they might be recommend quality indices of standardization for salt-fermented liquefaction of anchovy. As for the relation between fermentation period(X) and individual free amino acid(Y), five kinds of free amino acids such as glutamic acid, valine, glycine, lysine, and alanine showed highly significant in their coefficient of determination in most of samples. They might be recommend as quality indices for salt-fermented liquefaction of anchovy during fermentation. The difference of taste between products of the rapid- and low salt-fermented liquefaction and the traditional salt-fermented liquefaction were caused by their composition of the free amino acids ratios, in which were umami, sweet, and bitter taste in the extracts of anchovy during fermentation. The appropriate fermentation period of the sample A was shorten 30 days than the sample B and 60 days than the samples C and 90 days than the sample D in the processing of anchovy.

  • In order to standardize a recipe of Jeung-Pyun, fermented rice cake, we studied the sensory, rheological and physicochemical characteristics of Jeung-Pyun in terms of fermentation time and ratio of ingredients. Jeung-Pyun fermented for 3 hours was higher in pH, better in taste, hardness and overall quality than that fermented for 7 hours. It was softer, and had more moisture and fine grain as the amount of added water increased. Jeung-Pyun made with 80% added water had the greatest volume. Jeung-Pyun without salt was the worst in color and flavor and the smallest in volume. As the Jeung-Pyun was added more sugar and Tak-Ju, the volume was more larger and the moisture was more less. Taste and overall quality of Jeurig-Pyun was not affected by the amount of Tak-Ju added. The pH of Jeung-Pyun was lower as it was added more Tak-Ju. Therefore, Jeung-Pyun which is fermented for 3 hours, with 70% water, 0.8% salt, 15% sugar, and 30% Tak-ju was the most acceptable one in terms of sensory qualities and physiochemical properties.
