  • We investigated the changes of chemical compositions during fermentation of salted anchovy by salting methods for the purpose of establishment of processing condition. Dehydration of anchovy meat occurred remarkably by dry salting compared with that by brine salting and salinity was higher in anchovy by brine salting than by dry salting. Dehydration and salinity were increased in more anchovy fermented at $20^{\circ}C$ than at $5^{\circ}C$. Total nitrogen content was lower in anchovy by brine salting than by dry salting. Amino nitrogen increased remarkably during fermentation of salted anchovy at $20^{\circ}C$, while increased slightly at$5^{\circ}C$. Amino nitrogen showed maximum value on 120 days in dry salting and on 30 days in brine salting at $20^{\circ}C$, respectively. The changes of VBN were similar to the changes of amino nitrogen. The brine salting accelerated hydrolysis of anchovy meat compared with that of dry salting at $20^{\circ}C$, and the hydrolysis were suppressed at $5^{\circ}C$, The POV increased rapidly in dry-salted anchovy than brine-salted anchovy. We suggested that the appropriate processing condition of salted anchovy is to ferment for 5-6 months at $5^{\circ}C$ by addition of $25\%$ salt after pre-salting of raw anchovy.

  • In odor to improve preference to small red muscle fish such as saury, sardine, herring, etc., a new seasoning and conditioning process was experimented using kimchi seasoning ingredients and organic acids. The sensory profiles during 60 days of conditioning at $5^{\circ}C$ showed better results in dry salting than in wet salting. The additions of rice bran in dry salting gave advantageous effect on the sensory evaluation of conditioned saury with kimchi seasoning. The counts of remained fine bones and hardness of backbones after 60 days of conditioning were about $50\%\;and\;23\%$ in wet salted product, and $38\sim41\%$ and $11\sim14\%$ in dry salted product respectively, as compared to raw saury, The decomposition of protein to amino acids was more severe in wet salted product than in dry salted product. Histidine, leucine, glutamic acid, alanine, and valine in order were abundant in wet salted product, but histidine, glutamic acid, arginine, leucine, and alanine in order were contained plentifully in dry salted product.

  • The changes of amine, nitrate and nitrite nitrogen in yellow corvenia were studied during its processing and storage in order to clarify the precursors of N-nitrosamine(NA) formation in the salted and dried yellow corvenia(Gulbi), prepared y using the different salting method like dry and brine salting by pure and curde salt. As a result, during the processing and storage of Gulbi, DMA and TMA contents were significantly increased in the yellow corvenia. And after 40 days storage the increase rate showed 25.7∼45.7, 3.3∼5.6 times higher than those of 0.3, 2.4mg/kg, respectively, while nitrite contents, during its processing and storage, were scarcely changed in the salted and dried yellow corvenia. During the processing and storage, of Gulbi, DMA and TMA contents were less produced in brine salted and dried yellow corvenia using crude salt than in sample prepared using were scarcely changed in the salted and dried yellow corvenia. During the processing and storage of Gulbi, DMA and TMA contents were less produced in brine salted and dried yellow corvenia using crude salt than in sample prepared using pure salt, while the former were more effective than the latter in inhibiting the production of nitrate and nitrite. Therefore, it was revealed that reduction of NA precursors such as DMA, TMA, nitrate and nitrite were more effective in preparing with the brine salting method than with the dry salting method.

  • We investigated the changes of free amino acid, ATP related compounds and sensory evaluation during ripening of dry or brine salted-anchovy. The total free amino acid content of the salted-anchovy ripened at $20^{\circ}C$ was higher than that of the salted-anchovy ripened at $5^{\circ}C.$ The IMP content of raw anchovy was higher than that of any other ATP related compound and decreased rapidly during ripening, resulting in increased hypoxanthin (Hx). The sensory evaluation results indicated 5 and 4 months for dry and brine salted-anchovy, respectively, as the minimum time required to obtain an adequate ripened salted-anchovy. We concluded that processing condition of ripened salted-anchovy was to ripened for 5 months at $5^{\circ}C$ by drying salting method.

  • This study compared quality changes among brined baechu cabbages manufactured by various salting methods and types of salt. Brine, brine and dry salting, and dry salting were used as salting methods. When baechu cabbages were salted by dry salting method, the salinity of brined baechu cabbage increased compared to salting by other methods, even though the quantity of salt used was small. In addition, salinities of leaf and stem were relatively equal among brined baechu cabbages using dry salting method compared to those of other methods. When baechu cabbages were salted using dry method at different salt concentrations (3%, 5%, and 10% of weight of baechu), brined baechu cabbage showed suitable salinity (1.41~1.42%) at 5% salt concentration. Among brined baechu cabbages prepared using dry salting method with different types of salt (purified salt, solar salt, and bamboo salt), bamboo salt produced the highest salinity. Brined baechu cabbages with solar salt and bamboo salt showed significantly lower counts of total aerobic bacteria and higher counts of lactic acid bacteria than others. These results indicate that baechu cabbage can be salted equally, and the amount of salt used can be reduced when baechu cabbage is salted using dry salting method. In addition, using solar salt and bamboo salt can increase the quality of brined baechu cabbage.

  • In 7 kinds of Gulbi purchansed from Yosu, Sunchon and Chinju, N-nitrosamine (NA) such as N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA) and N-nitrosodipropylamine(NDPA), were detected and their content was 2.8∼78.3$\mu\textrm{g}$/kg, trace and 0∼1.4$\mu\textrm{g}$/kg, respectively. This experiment was conducted to study the effect of processing conditions on NA formation in the salted and dried yellow corvenia(Guibi), prepared by using the different salting method like dry and brine salting by pure and crude salt. NDMA, NDEA and NDPA were not detected in raw sample, but NDMA content increased in yellow corvenia during its salting (27.6∼37.4$\mu\textrm{g}$/kg), and then drastically decreased in Gulbi stored for 40 days, ranging from 2.8 to 4.3$\mu\textrm{g}$/kg. Content of above NA was inhibited more effectively in the samples prepare with brine salting method than with the dry salting method during its processing and storage. Especially, NA in the sample prepared with brine salted and dried yellow corvenia using the pure salt was detected in the lower concentrations, and that of NDMA, NDEA and NDPA was 2.8∼27.6, trance and ND-2.7$\mu\textrm{g}$/kg, respectively.

  • This study examined the optimal salting drying method and processing conditions (salt concentration, curing time, dry temperature, and drying time) for preparing salted semi-dried common gray mullet (SSD-CGM) Mugil cephalus based on the moisture content, salinity, and overall acceptance using response surface methodology (RSM). The moisture content, salinity, and overall acceptance of SSD-CGM prepared with different salting methods revealed that dry salting was the optimal salting method for preparing high-quality SSD-CGM. The optimal drying method for preparing high-quality SSD-CGM based on the drying velocity and sensory color was hot air-blast drying. The results of the RSM program indicated that the optimal independent variables ($X_1$, salt concentration; $X_2$, curing time; $X_3$, dry temperature; $X_4$, drying time) based on the dependent variables ($Y_1$, moisture content; $Y_2$, salinity; $Y_3$, overall acceptance) for high-quality SSD-CGM were 5.6% for $X_1$, 2.7 h for $X_2$, $47.0^{\circ}C$ for $X_3$, and 8.5 h for $X_4$ for uncoded values. The predicted values of $Y_1$, $Y_2$, and $Y_3$ for SSD-CGM prepared under optimal conditions were 54.4%, 4.2%, and 6.3, respectively, while the experimental values were $55.2{\pm}1.0%$, $4.1{\pm}0.3%$ and $6.7{\pm}0.8$. The actual and predicted values did not differ.

  • In previous paper (Lee et al., 1983) processing method of sardine meat "surimi" was described as a part of the wort to develop new types of ready-to-cook food materials with dark fleshed fishes. As the other part of the work, processing of low salt mackerel fillet was investigated, in this paper, in which fresh mackerel was filleted, salted in brine or with dry salt for an adequate time until the expected salt concentration reached, washed, air dried (3 m/sec, 15 to $20^{\circ}C$), and finally packed individually in K-flex film bag by vacuum or $N_2$ gas substitution. Salting time and salt concentration of brine was decided by the salt level penetrated into the fillet. As the final salt level was fixed to 4 to $5\%$, salting for 20 hours with $10\%$ dry salt or in $15\%$ brine at $5^{\circ}C$ was enough to get that level of salt. If the final salt level was set 5 to $6\%$, salting for 20-24 hours with $15\%$ dry salt or in $20\%$ brine was adequate. Salt penetration, however, was not much influenced by salting method and temperature. Changes in VBN and salt soluble protein occurred more rapidly in cases of salting with dry salt at $20^{\circ}C$ than salted in brine at $5^{\circ}C$, although it was not significant in the period of 20 to 24 hours. Oxidation of lipid and histamine formation during salting at $20^{\circ}C$ could not be neglected if it was delayed loger than 25 hours. Insolubilizing the salt soluble proteins during the storage of salted fillet occurred rapidly regardless of storage temperature. Browning and histamine formation, however, was depended on temperature and packing condition. In case of air pack, deterioration by browning and rancid was deeply developed but not the case for the packs by vacuum or $N_2$ gas substitution. The shelf-life of the salted mackerel fillet based on panel scores of brown color and rancidity, appeared 21 days for the air packed, and more than 30 days for vacunm or $N_2$ gas packed fillet at $20^{\circ}C$.

  • Chemical analysis of salted fish was analyzed in 60 samples collected from various moloha markets in Sohag, Qena and Aswan Governorates, Upper Egypt. Moloha contained 52.9% water content, while organic matter content represented 71.79% of dry weight and 33.81%($338.12{\pm}8.64mg\;g^{-1}$) of fresh weight. Total salts and soluble salts represented 13.29% and 10.19%($132.88{\pm}7.65\;and\;101.93{\pm}5.76mg\;g^{-1}$ of fresh weight), respectively. pH values were more or less neutral. Mycological investigation of examined samples revealed that fifty-five fungal species and one variety belonging to 11 genera were identified. The fungal genera of highest occurrence and their respective number of species were Aspergillus(A. flavus, A. niger, A. fumigatus, A. montevidensis, A. ficuum, A. parasiticus and A. mangini) and Penicillium(P. citrinum, P. puberulum, P. aurantiogriseum and P. roquefortii). On the other hand, yeast represented 18.2% and 3.0% of total counts of fungi on Czapeks-dextrose agar and 15%NaCl-Czapeks-dextrose agar media, respectively. Samples were assayed for potential presence of mycotoxins. Ten out of 60 samples(16.7%) were proved to be toxic. It is the first record of mycotoxins contamination of salted fish in Egypt. The ability of 340 isolates of recovered fungi was screened for production of mycotoxins and extracellular enzymes.

  • Salted and dried yellow corvenia(Pseudosciaena manchurica), so called 'Gul-bi', is one of nation-widely consuming fish foo::ls. It is suitable for a long term preservation and its pro-duce is also a great deal on sea food processing in this country. The texture of 'Gul-bi', however, have often appeared to be a delicate factor for the quality of the product. The loss or dislocation of fat in the tissue of the fish resulted by salting and drying is believed to profoundly relate to the texture of product. In this paper, the tissue of yellow corvenia and movement of fat were microscopically observed before salting, immediately after salting, and after drying and the results observed in the tissues dry salted, brine salted, and brine salted with the addition of BHA were compared. The cross section of yellow corvenia muscle showed that a distinctive border by connective tissue between white and red muscle could not be seen in general, and red muscle was surrounded by hypodermic fatty tissues. In the tissue of fresh yellow corvenia, the fat was mainly distributed in hypodermic fat layer which located under the corium while rarely distributed in white muscle. It was found that some parts of the fat in the tissue were permeated into intermuscular tissue passing through the connective tissues during salting. The result Was the same in both dry-salting and brine-salting tissue. However, the fat translocated into intermuscular tissues disappeared during drying process in the salted without BHA tissues whereas in BHA added tissue. This result suggested that BHA may take a role of multiple effect in translocation of fat in tissues as well as in retarding oxidation. In an advanced stage of salted and dehydration, the muscle fibers were ajoined together and then limits between muscle fibers already became indistinguishable. And the migrated fat into intermuscular tissue aggregated around the connective tissue and are apt to gradually to flow out from the muscular system through these tissues.
