  • This study was conducted to inhibit histamine formation in salt-fermented anchovy Engraulis japonicus fish sauce, by lowering the pH using 1% citric acid as food additive during the initial fermentation stage. The fish sauce samples were prepared with fresh anchovies used immediately after being caught (F), and left at ambient temperature for 4 h, and 24 h with 25% salt, 1% citric acid, and without citric acid for a 6-month fermentation period. The content of ammonia nitrogen, total nitrogen, and glutamic acid in fish sauce was unaffected by the addition of citric acid during the fermentation period. The histamine content of F and 4 h samples were 20.5-30.6 and 77.4-119.3 mg/kg, respectively. The histamine content of F and 4 h samples with 1% citric acid was 4.1-8.7 and 50.4-56.1 mg/kg, respectively. Furthermore, addition of citric acid did not inhibit histamine formation in 24 h sample that had lower freshness quality. Additionally, effective inhibition of histamine is observed during manufacturing of salt-fermented anchovy fish sauce on an industrial scale, suggesting that lowering the initial pH using 1% citric acid does not alter the taste and flavor of the fish sauce.

  • The present work was to study the changes of nonvolatile amines and microorganism in fermentation of anchovy during 12 weeks with addition of various concentration of sodium chloride. Changes of histamine occured significantly during fermentation of anchovy with 10, IS, 20% salt and 10% mixed salts (5.0% NaCl+5.0% KCl). A maximum histamine content was observed in anchovy fermented for 6 weeks while the change of histamine content was not with addition of 20% sodium chloride. Tyramine was found at highest contents in the fermented anchovy of 10% mixed salts and increased markedly in all anchovy fermented for 8 weeks. Cadaverine content was higher in fermented for all fermentation periods than in raw. During fermentation cadaverine contents increased significantly in fermented with 10% mixed salts. In contrast with that, fermented anchovy with 20% sodium chloride had very low those content and high sodium chloride concentration had influenced on amine formation. Although the highest content of putrescine was observed in fermented for 8 weeks, those content was not changed significantly during fermantation. The growth of Microflora, Achromobacter, Aeromonas and Pseudomonas were found in the in itial fermantation and Micrococus, Pediococcus, Lactobacillus and Saccharomyces were found during all fermentation periods.

  • To develop a value-added anchovy Engraulis japonicus sauce, the processing conditions and quality characteristics of a rapidly fermented and high-purity anchovy sauce (RRAS) were examined by adding 5-10% (w/w) radish Raphanus sativus L. RRAS exhibited higher yield, total nitrogen content, and amino nitrogen and calcium contents as well as lower salinity than those of conventional anchovy sauce (control). The salinity, yield, and total amino acid contents of RRAS and control were 17.2-17.7% and 19.6%, 81.2-88.7% and 61.0%, and 13,117.8-14,174.9 mg/100 g and 10,041.1 mg/100 g, respectively. The major amino acids recorded were aspartic acid, glutamic acid, alanine, valine, isoleucine, leucine, phenylalanine, ornithine, lysine, and histidine. The histamine contents of RRAS and control were 8.3-8.6 mg/100 g and 19.2 mg/100 g, respectively, while the protease activity levels were 0.901-0.958 unit/mg and 0.695 unit/mg, respectively. Overall, this study establishes that RRAS can not only significantly shorten the salt fermentation period, but can also serve as an anchovy sauce with superior nutritional quality and higher levels of amino acid and calcium.

  • This study was conducted to investigate the changes in organoleptic characteristics by adding different amounts of red pepper powder, salt-fermented anchovy extracts to kimchi. The salt enhanced sourness and pungency up to 2% but suppressed sourness, pungency, sweetness and umami taste by salt of more than 2%. Red pepper powder proportionally enhanced sourness up to 3% but suppressed saltiness, sweetness and umami taste. Salt-fermented anchovy extracts enhanced saltiness and sweetness together with enhancement of umami taste, but suppressed pungency and sourness. As the result of one-way analysis of correlation with the above tastes of spices and kimchi, saltiness of NaCl had a significantly negative correlation with pungency, sourness, sweetness and umami taste, as -0.9857, -0.9878, -0.9847, -0.9076, respectively, and pungency of red pepper with sourness, sweetness, saltiness and umami taste, as -0.8353, -0.9316, -0.9020, -0.9901, respectively. This indicated that increase of pungency and saltiness of kimchi suppressed a overall taste of kimchi. In addition, umami taste had a significantly negative correlation with only pungency as -0.9823 and a significantly positive correlation with sweetness and saltiness, showing a different tendency with pungency and saltiness.

  • This study examined the effect of calcium (AC) extracted from salt fermented anchovy Engraulis japonicus on osteoporosis in ovariectomized (OVX) SD female rats. After AC treatment for 8 weeks, the body weight of the OVX-AC group decreased, while the weight of the OVX group (control) increased 43.9%. The blood osteocalcin, calcium, and ALP levels were examined as physiological markers for osteoporosis. The concentrations of all markers were elevated in the OVX-AC group compared to the OVX group. Thus, anchovy calcium is useful as an organic calcium supplement.

  • This study was conducted to compare the food quality of commercial salt-fermented silver-stripe round herring (SFS) to that of commercial salt-fermented anchovy (SFA). The contents of moisture and crude protein of SFS were higher than those of SFA. However, the crude lipid and crude ash contents of SFS were lower than those of SFA. The salinity of SFS was 13.2%, which was lower than that of SFA. The taste value of SFS was 148.1, which was higher than that of SFA. The total amino acid content of SFS was 18.1 g/100 g and its major amino acids were glutamic acid (9.5%) and aspartic acid (8.1%). The contents of calcium, phosphorus and iron in SFS were 647 mg/100 g, 363 mg/100 g and 4.1 mg/100 g, respectively. Twenty six types of fatty acids were detected in SFS and the major components were 16:0, 18:0, 18:1n-9 and 22:6n-3. The angiotensin I converting enzyme (ACE) inhibiting and the antioxidative abilities of SFS were 50.0% and 1.15, respectively, which were similar to those of SFA. Sensory evaluation revealed that SFS had a superior taste and color to SFS, while to the flavor of two products was similar.

  • A study on the hydrolysis of anchovy using proteolytic bacteria isolated from anchovy jeotkal (a salt-fermented fish) was carried out to develop a rapid process of liquefied anchovy jeotkal. Five kinds of proteolytic bacteria, such as Staphylococcus sp.-l, Photobacterium sp., Volcaniella sp., Staphylococcus sp.-2 and Bacillus sp., were isolated from the anchovy jeotka1 that fermented with $20\%$ NaCl at room temperature for 2 months. Those grew well at $40^{\circ}C$, pH 7.0 on TPY broth with $2.0\%$ NaCl. The optimal hydrolysis temperature, pH, time and proteolytic bacteria densities for hydrolysis of minced anchovy were$40^{\circ}C$, 7.0, 6 hours and $1.8\times10^8$ cells/g raw anchovy, respectively.

  • The changes of contents in trimethylamine oxide nitrogen(TMAO-N), trimethylamine nitrogen(TMA-N), dimethylamine nitrogen(DMA-N), nitrite nitrogen(nitrite-N), nitrate nitrogen(nitrate-N) and the effect on the formation of N-nitrosamine(NA) during fermentation were investigated with salted anchovy added different amounts of sodium nitrite, sodium nitrate and ascorbic acid, respectively. When the sodium nitrite was added in salted anchovy, the contents of nitrite-N was decreased during fermentation . Whereas the formation of N-nitrosodimethylamine(NDMA ) was increased . Contents of TMAO-N was decreased, while TMA-N and DMA-N were increased during fermentation in all samples. Addition of ascorbic acid inhibited the formation of NDMA significantly. The formation of NDMA was inhibited by 81.3% at the concentration of 130mM as compared with non-added the control group. The aqueous model system was used for the evaluation of ascorbic acid(inhibitor) or thiocyanate (promoter) on the formation of NDMA using salt-fermented anchovy added with sodium nitrite. The optimum pH on the formation of NDMA was shown to be 3.8, and ascorbic acid inhibited the formation of NDMA whereas thiocyanate promoted. NDMA was not detected in the salt-fermented anchovy (control sample). However it is a possibility to form carcinogenic NDMA in stomach if both saltfer-mented anchovy and the materials contained abundant nitrite or nitrate were took in.

  • To investigate changes of components in salt-fermented anchovy sauce by long fermentation, various chemical properties were examined. The moisture, crude protein, crude lipid, and crude ash contents of the anchovy sauce by fermentation were 67.48~69.35%, 5.47~7.40%, 0.27~0.47% and 23.82~24.12%. The moisture and pH was decreased slightly, but the contents of crude protein, crude lipid, acidity and amino-N degree were increased gradually by long fermentation. And contents of crude ash, VBN and salinity showed almost no change. Total free amino acid contents of 1, 3, 6, 9 and 12 year fermented samples were 8,762.2 mg%, 9,484.6 mg%, 10,085.8 mg%, 10,650.7 mg% and 10,123.7 mg% respectively. Major free amino acid of samples were glutamic acid, leucine, lysine, alanine, valine, isoleucine in ordor. The samples were caused by their composition of the free amino acids rations, in which were umami, sweet and bitter taste in the extracts of anchovy during long fermentation. In Hunter values, fermented samples were generally lower in L, b values whereas higher in a, ${\Delta}E$ values. And absorbance at 453 nm was increased gradually by fermentation. Sensory evaluation result of samples, 6 years sample was the highest than the others in overall acceptance.
