  • Seasoned and dried squid slice (SDSS) was prepared with surimi and squid, and investigated on the food component characteristics. The moisture and water activity of the SDSS slightly increased with increasing addition ratio of squid. According to the increase of addition ratio of squid, sensory scores of SDSS decreased in the color, whereas increased in the taste. There was, however, no difference in sensory flavor and texture between SDSS prepared with various ratios of squid. The results of physical properties and sensory evaluation suggested that the desirable addition ratio of squid was more than 70% based on the mix for preparing SDSS. There was no difference in total amino acid content between seasoned and dried slices with, which was prepared by a ratio of squid(70): surimi (30), and without squid. The major amino acids of SDSS were glutamic acid, leucine, lysine and threonine. The calcium and phosphorus contents of SDSS were 85.9 mg/100g and 458.3 mg/100g, respectively. The total free amino acid content and taste value of SDSS were 3,1991mg/100g and 402.00, respectively. The taste values of SDSS suggested that the major taste-active compounds were glutamic acid and aspartic acid.

  • This study was, firstly, to investigate water holding capacity in terms of variation of moisture sorption isotherms of seasoned squid treated with sodium lactate, glycerol, propylene glycol, sorbitol, mannitol, sodium benzoate, potassium sorbate and calcium propionate, and secondly, the effect of humectant treatments on storage stability was studied. The criteria for storage stability was based on three quality factors, namely, lipid oxiations, color development by non-enzymatic browning reactions and lipid oxidation, and mold growth. The effect of humectants on equilibrium moisture content was in the following increasing order; mannitol < sorbitol < sodium lactate < propylene glycol < glycerol. The experimental data indicated that sodium lactate has, in practice, potentially positive effect on processing of seasoned squid. During the storage period of 60 days, TBA values increased in all samples tested as humectants concentrations increased up to 10%. However, in the range of 1-7% sodium lactate treatment, the degree of lipid oxidation, browning reactions and mild growth were not high enough to affect the quality of seasoned squid, when compared with conventionally manufactured ones.

  • This study examined microbial contamination during seasoned and dried squid Dosidicus gigas processing, including the apparatus, machines, and employee's gloves at each step in processing at two companies. The numbers of bacteria floating in air in each processing area were also examined. The numbers of Staphylococcus aureus (3.6-6.0 log CFU/g) and Escherichia coli (1.3-1.4 log MPN/100 g) in domestic and imported daruma (a semi-processed product of seasoned and dried squid) at companies A and B exceeded the regulatory limits of the Food Sanitary Law of Korea (S. aureus, ${\leq}2.0$ log CFU/g; E. coli, negative). S. aureus in both daruma was reduced to below the detection limit or 3.6 log CFU/g after the roasting step, but increased again to 3.3 and 5.5 log CFU/g after the mechanical tearing step at companies A and B, respectively. E. coli showed similar tendencies at both companies. The surfaces of the apparatus, machines, and employee's gloves that contacted daruma were also contaminated with S. aureus (1.0-5.5 log CFU/$m^2$) and E. coli (negative-to 3.5 log MPN/$m^2$). The numbers of bacteria floating in air were high (1.7-5.1 log CFU/$m^3$) at both companies. These results suggest that sanitation standard operating procedures (SSOP) must be developed to control of microbial cintamination in seasoned and dried squid.

  • It was reported that green tea extract has antioxidant and antimicrobial activities. To improve the quality of seasoned squid, green tea water extract was sprayed on seasoned squid (water content 25%) and water content was adjusted to 27% and 29%. During storage at $30^{\circ}C$, TBA value, total plate count, browning were analyzed. Browning were analysed by 3 different method (absorbance of water solubilized color, 5% KOH-methanol solubilized color and color difference meter). Water and 5% KOH-methanol solubilized color showed good correlation, but color index detected by color difference meter was not. Green tea water extract slowed TBA value increment and reduced total plate count, so it was supposed that green tea water extract acts positively in manufacturing seasoned squid.

  • Changes in proximate composition and protein quality were determined to find out appropriate processing conditions of the seasoned and smoked squid(Neon flying squid, Ommastrephes bartrannii). Moisture and crude protein contents were severely reduced (p<0.05), while increasing of fat and ash contents were not apparent. Seasoning and smoking contributed iii enhancing TBA value. Trypsin inhibitor(Tl) content was not increased severely after those processing steps. TI content checked in the all steps of squid processing was not correlated with the TBA value of squid in the same processing step. An improved digestibility and protein efficiency ratio(PER) were observed in the all products except with steak(mechanically soften product) in vitro enzymatic digestibilities of both raw Neon flying squid meats(mantle and arm) were significantly inferior(p<0.05) to other squid species.

  • Fish sauce is a liquid form of salt-fermented fish and has played an important role in Korean dietary life. Fish sauce was manufactured by utilizing Alaska pollack scrap from Himedara(seasoned and dried Alaska pollack tail) processing . In addition, the effects of squid viscera as a fermentation enhancer were also evaluate.Ph of Alaska plllack scrap sauce with squid viscera was lower than that of control over the entire fermentation process. Squid viscera acceleraged the production of amino-nitrogen, VBN , TBA and free amino acids, and the degradation of IMP and Inosine. The addition of squid viscera and koji at 5% concentration, respectively , also accelerated the digestion of Alaska pollack scrap and was similar to the results of squid viscera at 10% concentration.

  • Traditional fermented fish products 'Jeodtgal' have been prepared with addition of about $25\%$ salt to prevent spoilage, but domestic seasoned and fermented products have only about $8\%$ salt, so they have been required careful treatment during distribution and could have a different fermentation pattern from traditional 'Jeodtgal' This study was conducted to establish shelf-life of seasoned and fermented squid at different distribution conditions. To establish shelf-life of seasoned and fermented squid stored at $10^{\circ}C,\;20^{\circ}C$ and $30^{\circ}C$, chemical components and sensory evaluation were investigated. Chemical components such as volatile basic nitrogen(VBN), ammonia nitrogen ($NH_3-N$) and total nitrogen(T. N) rapidly increased during storage at $20^{\circ}C$ and $30^{\circ}C$, but pH value and Hunter color value(${\Delta}E$) slowly decreased during storage without respect of storage temperature. Judging from chemical components analysis and senseory evaluation, seasoned and fermented squid could be storage for 3days at $30^{\circ}C$, 7days at $20^{\circ}C$ and 25days at $10^{\circ}C$, respectively. The ratio of quality deterioration per hour were 0.00166 at $10^{\circ}C$, 0.00595 at $20^{\circ}C$ and 0.01385 at $30^{\circ}C$.

  • This study was designed to evaluate the potential of using high pressure processing (HPP) for extending shelf life of seasoned squid during refrigerated storage. The vacuum-packed seasoned squid samples were subjected to 400 MPa for 20 min using a custom-made high pressure processor. Microbial counts, dimethylamine (DMA), trimethylamine (TMA), total biogenic amine, autolytic activity were determined on days 0, 7, 14, and 21 of refrigerated storage. The numbers of indigenous bacteria were effectively reduced by 2.77 log CFU/g after HPP treatment. The amounts of DMA and TMA produced in the control samples increased up to 15.99 and 42.82 mg/g after 7 days of refrigerated storage when compared to 5.27 and 10.21 mg/g the HPP-treated samples, respectively. The autolytic activity of the HPP-treated sample (4.32 nkat/g) significantly lower than that of the control (7.13 nkat/g) after 7 days of refrigerated storage. Therefore, HPP can be applied as a potential squid processing method microbiological safety and shelf life.

  • This study aimed to optimize mixing conditions (adding amount of squid skin and sea tangle Saccharina japonica) for concentrates of octopus Octopus vulgaris cooking effluent (COCE) and roasting conditions (temperature and time) of seasoned Laver Pyropia yezoensis with concentrates of octopus cooking effluent (SL-COCE) using response surface methodology (RSM). The results of RSM program for COCE showed that the optimum independent variables ($X_1$, squid skin amount; $X_2$, sea tangle amount) based on the dependent variables ($Y_1$, odor intensity; $Y_2$, amino-N content; $Y_3$, sensory overall acceptance) for high-quality COCE were 0.53% (w/w) for $X_1$ and 0.48% (w/w) for $X_2$ for uncoded values. The results of the RSM program for SL-COCE showed that the optimum independent variables ($X_1$, roasted temp.; $X_2$, roasted time) based on the dependent variables ($Y_1$, burnt odor intensity; $Y_2$, water activity; $Y_3$, sensory overall acceptance) for high-quality SL-COCE were $344^{\circ}C$ for $X_1$ and 8 sec for $X_2$ for uncoded values. The SL-COCE prepared under optimum procedure was superior in sensory overall acceptance to commercial seasoned laver.
