  • 여러 종류의 소금으로 절임한 배추로 김치 담금 후 $25^{\circ}C$에서 숙성시키면서 품질변화를 조사한 결과, 모든 김치에서 pH는 담금 직후부터 감소하여 2일 후에 최적가식 범위인pH 4.2에 도달하였고, 산도도 pH의 결과와 동일한 양상을 나타내었다. 염도는 각 소금의 종류에 따라 침투력의 차이를 보여 절임효율이 높은 세척 탈수염과 기계염이 다른 김치 보다 높은 염도를 나타냈다. 김치발효 미생물의 경우 총균수는 기계염에 비해 다른 종류의 소금으로 제조한 김치에서 그 생육양상이 빨리 진행되었고, Lactobacillus속의 경우 발효 7일째까지 계속 증가하는 경향을, Leuconostoc속의 경우 숙성 4일째까지 증가하다가 감소하였다. Pediococcus속은 숙성 중기부터 증가하여 완만한 증가와 감소를 나타내었으며, Streptococcus속은 숙성 6일 후에 급속히 감소하는 경향을 나타냈다. 유산균의 경우 소금종류에 따라 큰 차이는 없는 것으로 판단되었다. 김치 발효과정 중 생성된 유기산등 여러 성분들과 반응하여 김치숙성이 시작되는 2일째에 색도 변화는 L, a 그리고 b값이 크게 감소하였다. 김치의 텍스쳐는 절임초기에 급격히 감소하였다가 절임시간이 증가하면서 경향은 뚜렷하지 않으나 전반적으로 감소하는 경향을 나타냈다. 천일염, 세척탈수염, 기계염, 환원염을 사용하여 제조한 김치는 서로 뚜렷한 이화학적, 물리적, 미생물학적 차이가 없었지만, 김치의 숙성 중 산도의 변화 및 총균수에 대한 생육양상의 결과로 볼 때 기계염 보다는 천일염의 경우가 김치발효에 더욱 효과적인 것으로 판단되었다.

  • The enzyme activity and organoleptic properties of Korean pickled cucumber were studies for their changes during fermentation. The Korean pickled cucumber were prepared by blanching and high temperature soaking in salt solution and trehalose treatment The results shelved that the effect of combined heat and trehalose treatment significantly reduced the fermentation rate and softening rate of texture while a rather rapid fermentation was for those pleserved with salt. The effect of trehalose treatment enhenced fermentation and it was significantly reduced softening rate of texture by 2% treatment. The sensory evaluation of Korean pickled cucumber was found that combined heat treatment with blanching and hot solution had a positive effect for reduction of softening of cucumber tissue, however, odor and taste were not significantly affected. This study suggested that combined heat and trehalose treatment might have potential for affording protection against softness of cucumber tissue during the fermentation time.

  • This study examined the development of a low-salt fermented seafood product using an ascidian (Halocynthia roretzi), and the optimum processing conditions and quality characteristics of the low-salt fermented ascidian (LSA). The optimum processing conditions for the LSA were as follows. The ascidian was shelled and its muscle sliced into 5 mm widths. This was soaked in a 10% salt and 1% sodium erythorbate solution for 20 min. The solution was drained and then the muscle was soaked in 0.1% sodium bisulfite solution for 1 min. To this was added a 1:1 mixture of anchovy sauce and rice gruel, and it was fermented at $5^{\circ}C$ for 15 days. The moisture content and salinity of the LSA were 75.0-75.4% and 8.0-8.5%, respectively. During salt-fermentation at $5^{\circ}C$ for 20 days, the amino-N content of the LSA increased, and the texture softened gradually. The viable cell counts in early salt-fermentation were $4.2-4.5{\times}10^4CFU/g$, and this decreased gradually. The ratio of saturated fatty acids tended to increase in early salt-fermentation, while that of polyunsaturated fatty acids decreased slightly. Chemical experiments and sensory evaluation showed that the dipping treatment in 1% sodium erythorbate solution and 0.1% sodium bisulfite solution resulted in a good color and prevented browning of the salt-fermented ascidian meat. Moreover, adding anchovy sauce and rice gruel mixture improved the flavor of the LSA.

  • 식염 5%를 첨가한 저염 오징어 젓갈을 $10^{\circ}C$에서 8주간 숙성시키면서 핵산관련물질의 변화를 분석하였다. 숙성발효에 따른 정미성분의 변화를 보면, 핵산관련물질 중 ATP 및 ADP는 소실되어 검출되지 않았으며 초기에만 AMP가 존재하고 숙성중반까지 현저히 감소한 반면에 inosine 및 hypoxanthine은 숙성중반까지 증가하였다가 다시 감소하였으며 핵산관련물질의 대부분을 차지하였다. pH는 식염농도가 낮고 숙성온도가 높을수록 숙성후반까지 계속 유의성 높게 증가하여 숙성이 촉진되었으며 적정산도는 숙성후반까지 감소하였다. 이상의 결과처럼 저염 오징어 젓갈의 적정 발효조건을 추정해 보면 발효온도 $10^{\circ}C$, 식염 10%, 발효기간 5주로 추정되어 활용가치가 높다고 사료된다.

  • In order to develop value-added low-salt fermented seafood with a long shelf-life, we prepared seasoned low-salt fermented Mideoduck (Styela clava) supplemented with fermentation alcohol (SME). The SME was produced by washing and dewatering shelled Mideoduck, followed by cutting and salting for 24 h at 0℃. The salted Mideoduck was seasoned and fermented with ingredients, including garlic, ginger, monosodium glutamate, red pepper, sesame, sorbitol and sugar, for 7-8 days at 0℃. After adding 3-5% fermentation alcohol, the Mideoduck was packed in a polyester container. The salinity, volatile basic nitrogen, and amino nitrogen content of the SME was 4.5%, 20.9 mg/100 g and 92.0 mg/100 g, respectively. In comparison with the control, the addition of 3-5% fermentation alcohol showed inhibitory effects of decreased freshness, texture degradation, and growth of residual bacteria. Additionally, the SME had good storage stability and organoleptic qualities when stored at 4±1℃ for 40 days. Therefore, it is suitable for commercialization as a seasoned low-salt fermented product with a long shelf-life. The total amino acid content of the SME was 11,774.5 mg/100 g, majorly comprising glutamic acid, aspartic acid, lysine, arginine, and leucine, and the free amino acid content was 506.4 mg/100 g, majorly comprising hydroxyproline, taurine, and glutamic acid.

  • The effects of salting methods on sensory and microbiological properties of Kakdugi were evaluated during fermentation at 10$\^{C}$ for up to 52 days. Kakdugi samples were prepared by 4 different salting methods at the final salt concentration about 1.5%, which was appropriate for organoleptic quality. The salting methods for radish cubes(2cm size) of Kakdugi included; 1) Treatment S-1: spraying dry salt uniformly onto the radish cubes, at the concentration of about 1.5%(w/w) and cured for 1 hr, 2) Treatment S-5: spraying dry salt uniformly onto the radish cubes, at the concentration of about 1.2%(w/w) and cured for 5 hr, 3) Treatment B-1: brining radish cubes in a 8.5%(w/v) salt solution and cured for 1 hr, 4) Treatment B-5: brining radish cubes in a 4.0%(w/v) salt solution and cured for 5 hr. During the early stage of fermentation, sensory test showed higher scores in the overall acceptability of Kakdugi prepared with salting methods S-1 and S-5 than those with B-1 and B-5. However, the trend of acceptability has been reversed by the treatments B-1 and, more notably, by B-5 at the later stage of fermentation. The counts of lactic acid bacteria increased remarkably and then decreased gradually after the optimum ripening period. The major lactic acid bacteria isolated and identified from Kakdugi were Pediococcus, Streptococcus, Leuconostoc, and Lactobacillus.

  • The anchovy, Engraulis japonica, were prepared with two different salt concentration of 20%, 10% which was added 2, 5, 5 and 10 % of grind garlic(LSA 1, 2, 3, 4) and garlic juice(LSB 1, 2, 3, 4), respectively. The experimental samples were taken at 30, 60, 90 and 110 days fermentation, which were analyzed VBN(volatile basic nitrogen), amino acids, nucleotides and their related compounds and amino acids. VBN increased rapidly until 110 days fermentation, its contents in samples containing of 10% salt(CB) were increased about 2.4 times as compared with those of 30 days fermentation. And then its contents of 110 days fermented samples increased at average 2.3 times more than 30 days fermented samples containing grind garlic of 2, 5, 8% and garlic juice of 2%. Nucleotide and their related compounds were detected AMP, UMP, IMP, inosine and hypoxanthine. Hypoxanthine was dominants in all samples and increased steadily during fermentation of anchovy. The contents of composition amino acids decreased gradually during it's fermentation, but those content decreased 33% in CO group, 42% in the CB group and 38%(average) in the other garlic added low salt groups.

  • This study investigated the quality characteristics of black soybean paste(Daemacjang) with black soybean content and salt concentration. The total acidity increased as the pH decreased during fermentation period. The amino-type nitrogen content of all samples increased significantly during fermentation time. Total cell counts was not significantly different during fermentation, and mold counts decreased at 3 log cycles. The cell counts of lactic acid bacteria decreased approximately 2 to 3 log cycles in 10% salt concentration (treat B and C), and were not detected in treat A and D. Total polyphenol contents of treat A, B, and C were 42.77%, 52.99% and 52.95% during fermentation up to 70days, respectively, which was higher than D (39.86%). In a sensory evaluation, treat B showed the highest scores for overall acceptability.

  • This study was performed to examine the effects of salt addition levels on changes in the physicochemical properties of salted and fermented shrimp for HACCP determination. The salted shrimp were prepared from fresh shrimp using different concentrations (8, 18, 28%) of chunil salt, and were then fermented at $10^{\circ}C$ for 160 days. Amino nitrogen, VBN and TMA contents rapidly increased in the 8% group during the fermentation period, while the 18% and 28% groups maintained their initial levels throughout the 160 day fermentation period. The thiobabituric acid (TBA) values of the groups increased rapidly over 120 days of fermentation, and then decreased thereafter. The TBA values of the 18% and 28% groups were lower than that of the 8% group. The peroxide values of the 18 and 28% groups rapidly increased over 30 days of fermentation, whereas the values for the 8% group, rapidly increased with 60 days of fermentation.
