  • The sucrose, MSG, fresh oyster and salted-fermented anchovy and shirmp were added into Kimchi in the concentration range of $1{\sim}3%$ and studied for their effects on the changes in chemicl properties and fermentation rate. The control Kimchi was prepared with addition of 2% red pepper, garlic, Welsh onion and 1% ginger. It was found that the fermentation rate was increased as the concentration of all of ingradients tested increased. Among them M.S.G affected most significantly. However, ascorbic acid formed was reduced for those Kimchi added with salted-fermented anchovy and shrimp while the changes in pH and titrable acidity was affected a little.

  • Gamma irradiation was applied to develop fermented shrimp product with lower salt concentration, high sensory quality and storage stability. Shrimp was prepared with 15 and 20% of salt and fermented at $15^{\circ}C$. The sample was irradiated for 15% added salt at the 4th week and for 20% at the 6th week during fermentation with 0, 5 and 10 kGy absorbed doses. The irradiation was applied at optimum stage of fermentation determined when the content of amino nitrogen(AN) arrived approximately 400 mg%. Chemical properties such as amino nitrogen(AN), volatile base nitrogen(VBN), trimethylamine(TMA) and neutral protease activity were examined during whole fermentation. The AN, VBN, TMA and protease activity were not affected immediately after gamma irradiation. The more NaCl concentrations and irradiation dose, the less content of chemical compounds and protease activity was found. From the results of chemical properties, it was concluded that fermented shrimp with 15% of salt and irradiated at 10 kGy before optimum fermentation, or 20% and 5 kGy or above were maintained the sound quality during storage compared with the control.

  • Here, we report the draft genome sequence of Latilactobacillus sakei subsp. sakei FBL10 isolated from Saeujeot (salted fermented shrimp). The draft genome consists of 2,285,672 bp with a G+C content of 41.1% and contains 2,282 coding genes. Genome analysis revealed that clusters associated with bacteriocin production were identified, in addition to several probiotic properties, such as stress resistance factors and aggregation. On the other hand, antibiotic resistance genes and virulence factors were not present. Pangenome analysis for 32 genomes showed 213 unique genes for FBL10 strain. These results demonstrate the beneficial properties of strain FBL10 as a putative probiotic.

  • Angiotensin converting enzyme(ACE) inhibitory activity of Kimchi added with salted-fermented fish products(SFFP), such as salted-fermented anchovy(SFA), salted-fermented anchovy sauce(SFAS), low salt-fermented anchovy sauce(LSFAS), salted-fermented small shrimp(SFS), low salt-fermented sandlance sauce(LSFSS) and their alternatives, such as oyster hydrolysate(OH), Alaska pollack hydrolysate(APH) and sea-staghorn extract(SSE) were studied during fermentation at $20^{\circ}C,\;10^{\circ}C\;and\;4^{\circ}C$. ACE inhibitory activities of Kimchi samples added with SFFP were increased until some fermentation period and then kept similarly constant levels at every fermentation temperature. Similar tendencies were occurred in amino nitrogen (AN) content. ACE inhibitory activities of Kimchi samples added with SFFP alternatives rapidly increased in 1st or 2nd day fermentation and then very slowly increased but AN contents showed roughly constant levels $(400{\sim}600\;mg/100\;g)$ in every fermentation temperature. Kimchi added with LSFAS had higher ACE inhibitory activity (>80%) with elevated level of AN (>600 mg/100 g) among the tested Kimchi samples. Kimchi samples added with SFFP alternatives also showed comparable activity to Kimchi added with SFFP This study shows that Kimchi added with SFFP and their alternatives is a good source as a functional food.

  • Nitrite scavenging activity of Kimchi added with salted-fermented fish products(SFFP), such as low salt-fermented anchovy sauce(LSFAS), salted-fermented anchovy sauce(SFAS), salted-fermented anchovy(SFA), salted-fermented small shrimp(SFS), low salt-fermented sandlance sauce(LSFSS) and their alternatives, such as oyster hydrolysate(OH), Alaska pollack hydrolysate(APH) and Sea-staghorn extract(SSE) were studied during fermentation at $20^{\circ}C,\;10^{\circ}C\;and\;4^{\circ}C$. Nitrite contents of Kimchi samples added with SFFP were roughly decreased except Kimchi added with SFS and SFAS, which increased at the 2nd day of fermentation. Fermentation of Kimchi at $4^{\circ}C\;and\;10^{\circ}C$ resulted a decrease in nitrite(<5 ppm). Nitrite contents of Kimchi samples added with SFFP alternatives rapidly decreased in the initial fermentation and then kept a low level (<2 ppm). Nitrite scavenging effects of Kimchi samples added with SFFP and their alternatives were steady during fermentation, showing a little variation in samples added with SFFP. Samples added with LSFAS and OH showed higher nitrite scavenging effects(90%) than others$(70{\sim}80%)$.

  • This study performed recognition and preference tests on hometown foods given to University students in NaePo province, which is in the northwest area of Chungnam, Korea. The results indicated that female students and people who majored in food science were less interested in hometown foods than male students or who are not majors in food science. Moreover, they preferred Korean-style foods to food from other countries. Mass media has aroused interest in hometown foods. However, hometown foods require standard recipes certain levers of autonomy for the population. Hometown foods are valuable and should be handed down the next generation through publicity. For example, Kkotgetang(blue crab soup) was the best known hometown foods followed by kkotgegang(fermented blue crab with sauce), saeujeot(salted and fermented shrimp), eorigul jeot(salted and fermented oyster with red pepper) in that orders. The most preferred food was kkokgetang(blue crab soup) followed by kkotgegang(fermented blue crab with sauce).

  • This study was performed to investigate the effects of salted and fermented shrimp ethanol extract (SFS) on serum lipid metabolism and hepatocytes in rats. Male Sprague-Dawley rats were administered 60% fat feed to induce hypercholesterolemia and were divided into five groups. Experimental groups were classified according to administered diet: normal diet group (NC), high cholesterol diet group (HC), high cholesterol and low dose shrimp extract (20 mg/kg) group (HC-SFSL), high cholesterol and high dose shrimp extract (200 mg/kg) group (HC-SFSH), and high cholesterol and lovastatin (20 mg/kg) group (HC-Lov). The experimental diets were fed ad libitum for 14 days. Compared with the control group, the serum cholesterol and triglycerides were 40.4 and 64.7% lower in the group fed HC-SFSH respectively. Low density lipoprotein (LDL)-cholesterol concentration in serum decreased in the HC-SFSH group compared with the HC group. In a histological assay, hepatocytes in the HC group showed that the vacuolated cells by fat appear clear due to the large amount of intracytoplasmic fat, whereas the liver hepatocytes in the group fed SFS effectively decreased fatty liver and intracytoplasmic fats. These results suggest that the extract of salted and fermented shrimp has an antiatherosclerotic effect and may lessen the effects of cardiovascular disease by reducing the cholesterol level in serum.

  • Five commercial salt-fermented shrimps contained 29.8~48.3% of salt 3.5%~7.3% of total nitrogen and 0.3~0.7g/100g of amino-nitrogen respectively. The average peptide length(APL) of five commercial salt-fermented shrimps ranged from 10.1 to 15.0. Sample B and E showed longer APL than the others with the values of 15.0 and 14.4 respectively. Protease activity showed the large differences in five samples from 17 unit to 232 unit ; sample C showed the highest protease activity with 232 unit while sample D and E were relatively lower with 17 unit and 18 unit respectively. The chitinase activities which can hydrolyze chitin the one of components on outer layer of shrimp ranged from 14.4 unit to 171 unit. Sample E had the highest chitinase activity as 171 unit but sample B showed the lowest activity with 14.4 unit. Chitooligosaccharides of five commercial salted-fermented shrimps were consisted of monoglucosamine diglucosamine and triglucosamine.

  • Traditional kakdugi prepared from salted radish by the addition of fermented shrimp or anchovy sauce along with seasonings and spices, e.g., red pepper powder, garlic or ginger, which has been examined for the formation of volatile nitrosamine(NA) during its fermentation at 5oC and 17oC. Changes of acidity were increased; while, those of ascorbic acid and pH were continually de creased and besides concentrations of salt were scarcely observed during the fermentation of kakdugi at 5oC and 17oC. High initial levels of nitrate in radish followed by a gradual decreased in nitrate concentration, along with increasing levels of nitrite, during its fermentation. During the fermentation of kakdugi, NA such as N nitrosodimethylamine(NDMA) and N nitrosodiethylamine(NDEA) was identified; these NA in kakdugi that had been prepared with shrimp sauce contained in the higher levels than kimchi that had been prepared with anchovy sauce, and both NDMA and NDEA were detected higher levels in the fermented sample at 17oC than in the fermented sample at 5oC. In kakdugi, NDMA and NDEA levels were continually increased during its fermentation; its levels after 35 days fermentation at 17oC were 0.5~16.7 and 0~5.2 g/kg in added shrimp sauce sample, 0. 5~8.7 and 0~4.7 g/kg in added anchovy sauce sample and 0.4~4.8 and 0~2.4 g/kg in control, respectively. The occurrence of NA such as NDMA and NDEA appeared to arise from the fermented sauce and radish used in preparation of the kimchi.
