  • One specimen (13.4 cm ML) of Chiroteuthis picteti belonging to the family Chiroteuthidae, firstly collected from Songjeong, Southeast coastal water of Korea on May 18, 2013. It was identified as C. picteti based on the following combination of morphological character: mantle slenderly cylindrical; fin oval shape, both lobes having no anterior free lobe, FL 58.2% of ML; arms long with a formula IV > III > II > I. We propose a new Korean name, "Kin-pal-o-jing-eo-gua", "Kin-pal-o-jing-eo-sok", and "Kin-pal-o-jing-eo" for the family, genus and species, respectively.

  • To utilize waste of squid effectively, antioxidant properities of squid viscera were elucidated. Major fatty acids of total lipid, neutral lipid and phospholipid were $C_{16:0},\;C_{18:1}\;and\;C_{20:5},\;C_{22:6}$ and consisted $63{\sim}71\%$ of total fatty acids. Total lipid did not show significant antioxidant activity when added to the fish oil at the concentration below $5.0\%$, Antioxidant activity of hexane extract was lower than total lipid or tetra carbon chloride-methanol($CCl_4-MeOH$) extract. Extracts with $CCl_4-MeOH$ exerted higher antioxidant activity as the methanol ratio was increased, suggesting that polar lipid plays and important role.

  • 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 was carried out to investigate the effect of emulsifiers on the characteristics of microcapsule containing squid liver oil. The emulsion stability of glycerine monostearate (HLB 4) separated after 1 hr. Sucrose fatty acid esters (monostearate: di-, tri-, and tetrastearate=6:4; HLB 11), sucrose fatty acid esters (monostearate: di-, tri-, and tetrastearate=7:3; HLB 16) and glycerine monostearate (HLB 4) plus sucrose fatty acid esters (monostearate: di-, tri-, and tetrastearate= 7:3; HLB 16) separated after 1 hr 30 min. The microencapsulation efficiency prepared by HLB 16 was 35.0%. The polyunsaturated fatty acid composition was shown to be higher than 50% in all powders, and the ratio of the polyunsaturated fatty acid composition to the saturated fatty acid composition was found to be the same (2.07) for HLB 11 and HLB 16.

  • As an investigation for utilization of squid viscera oil as a food source, we attempted to improve a quality of fish burger by addition of emulsion curd formed from gelatin, water and refined squid viscera oil. Judging from the results of peroxide value, brown pigment formation, color value of Hunter, jelly strength and sensory evaluation, the reasonable amount of emulsion curd for the improvement of a fish burger functionality was determined as 6% on the weight basis of the chopped mackerel meat. Total plate counts, volatile basic nitrogen and histamine contents in fish burger prepared by addition of 6% of emulsion curd were $6.2{\times}10^4\;CFU/g$, 19.0 mg/100 g, and 50.7 mg/100 g, respectively. It may be concluded, from the above results that the emulsion curd-added fish burger is a safe as a food commodity. The ratio of polyenes to saturates of emulsion curd-added mackerel burger was 1.13. By adding emulsion curd formed from gelatin, water and refined squid viscera oil, color in cross section, texture and lipid functionality of mackerel burger could be improved in part.

  • In an attempt to find ways of improving the quality and sanitary state of dried squid, this study compared artificial drying methods i.e. hot air drying and cold air drying with natural drying method. The drying rates of squid were in the order of hot air, cold air and natural drying. However, cold-air drying was slower than natural drying at $7^{\circ}C$. The drying rates increased with increasing drying temperature. When drying temperature was close to the dew point on a dehumidifier surface, which was the case with cold air drying at $7^{\circ}C$, the driving force for dehumidification was lower than under other drying conditions, which resulted in a lower drying rate. There were little color differences between the drying methods and temperature. Squid dried by cold air-drying had better mechanical texture and sensory qualities than with other drying methods. In addition, the cold air drying method maintained superior quality in terms of the contents of amino acids, taurine, EPA, DHA, other fatty acids and a low TBA value than the other drying methods.

  • Volatile components in natural and basic fraction of the steam distillation extraction method from squid during processing were analysed by GC and GC-MS equipped with a fused silica capillary column. Thirty eight compounds were identified; they were 31 compounds from neutral, 7 compounds from basic fraction. The main components flavor of squid were 3-methylthiophene, 2-methyl-2-hexanthiol, 1-penten-3-ol, 3-penten-2-ol, 3-ethyl-1,4-hexadiene, 1-hydroxy-2-propanone, hexenal and benzaldehyde etc.. Especially, (E, E)-3,-5-octadecanal were detected during the boiled. 2,5-dimethyl pyrazine, 2-ethyl-6-pyra-zine, 2,3,5-trimethyl pyrazine and 2-ethyl-3,5-dimethyl pyrazine basic compounds, which have respectively a burnt and roasted odor, are considered to be important for the characteristic basic fraction of squid.

  • Low-salted and fermented squid products, squid jeotkal was prepared and fermented at $10^{\circ}C$. During fermentation of squid, microbiological and chemical changes were examined. Sensory evaluation was also carried out. After 20 days of fermentation, taste and flavor of the squid jeotkal containing $10\%$ NaCl were proven to be the best; in contrast, the jeotkal with $7\%$ NaCl exhibited the highest sensory score. At the period showing the best flavor and taste, viable cell count reached to $10^8/g$. Throughout the fermentation period, types of microorganisms isolated were significantly different in squid jeotkal of different salinity. In general, protease producer and bacteria producing components of jeotkal-flavor and organic acids more likely contributed to producing the jeotkal of the best quality. pH of the squid jeotkal with $10\%$ salinity maintained under pH 7.0 throughout the fermentation periods; however, in the case of the jeotkal with $7\%$ salinity, pH increased over pH 7.0 after day 25. Similar tendency was observed in the results from VBN and hypoxanthine formation. Total nitrogen was decreased as fermentation proceeded; in contrast, total free amino acids were increased.

  • The purpose of this study was to analyze the microbiological hazards of prepared foods, raw materials, utensils and workers' hands and to evaluate cross-contamination of bacteria in foodservice establishments. Aerobic plate counts, coliforms, E. coli, E. coli O157:H7, Salmonella spp., Staphylococcus aureus and Listeria monocytogenes were tested. According to the microbiological evaluation, there were many cases of contamination of bacteria. Staphylococcus aureus was detected in chicken stew (Korean type), Japchae, Bibimbap and Kongnamul-muchim at the A foodservice establishment and Jwieochae-jorim at the B foodservice establishment. E. coli was detected in Ojingeochae-muchim at the C foodservice establishment. E. coli O157:H7, Salmonella spp. and Listeria monocytogenes were not detected in any of the tested samples. Critically, microbiological contamination of raw materials, utensils and workers' hands could result in contamination of prepared foods, thus, attention needs to be given to sanitation of raw materials, workers' hands and utensils to reduce or eliminate contamination of bacteria.
