The present studies were conducted to evaluate the sterilizing efficiency of the thermal processes for the canned sea-mussel products, such as canned boiled sea-mussel in brine (packed into No. 1 flat can) and canned smoked sea-mussel in oil (packed into No. 3B square can), with the purpose of deciding the adequacy of the processes. Heat penetration was tested three times with three cans at a time for each canned product. The tip of the applicator was fixed on the position a little below the geometrical center of the can. The test cans were placed in the middle layer of the basket in which the same canned products were loaded with, and the test cans were arranged to the front, the middle and the rear in the retort. The heat penetration curve of the canned boiled sea-mussel in brine showed a broken logarithmic heating curve while that of the canned smoked sea-mussel in oil showed a simple logarithmic heating curve. The calculated $F_0$ value for the canned boiled sea-mussel in brine was 25.33 and the canned smoked sea-mussel in oil was 13.84. Additionally, the nomographs represents the relationship between $F_0$ values and B values(process time including $42\%$ of come-up time) for the canned sea-mussel products were constructed.

This study was investigated to obtain basic data which can be applied to processing of canned seasoned sea mussel. Shell was washed and steamed for 10 min before shucking. Sea mussel meat was seasoned with mixed seasoning sauce(soy sauce 23%, monosodiun glutamate 2%, sorbitol 2%, sesame oil 1%, vinegar 2%, starch syrup 15%, water 55%) for 30 min The seasoned sea mussel 60 g was vacuum packed in RR-90 can and fill with seasoning sauce 30 mL and grape seed oil 30 mL respectively, and then there was sterilized for various Fo values(Fo 8~12 min) in a steam system retort at $121^{\circ}C$. pH, VBN, amino-N, total amino acid, free amino acid, color value, texture profile, TBA value, mineral content, sensory evaluation and viable cells count of the canned seasoned sea mussels sterilized with various conditions(Fo 8~12 min) were measured. The same experimental items were also measured during storage. There was no remarkable difference between sterilized conditions and sensual characteristics. The results showed that the product of filled with grape seed oil sterilized at Fo 8 min was the most desirable.

Specification and heavy metal contents of canned seafoods packed in oil were investigated. 30 species of canned tuna were classified by 4 groups as follow; group (sample codes, 1-10) composed of tuna and oil only, group (11-18) composed of tuna, vegetable and oil, group (19-27) composed of tuna, sauce and oil, and group (28-30) composed of tuna, vegetable, sauce and oil. Commercial canned shellfish packed in oil were mainly produced from sea mussel (sample codes, 31 and 32) and oyster (33-35). Can bodies of canned tuna were made by tin-plate, and used c-enamel or aluminium-paste as coating materials. In pH values of canned tuna, sample codes 1-10 (pH 5.55-5.69) and 19-27 (pH 5.17-5.85) were higher than sample codes 11-18 (pH 4.95-5.43) and 28-30 (pH 5.20-5.38). There was no difference in salinity (1.3-1.9%) and vacuum degree (15-18 mmHg) among canned samples. Heavy metal contents of canned seafoods ranged from 1.04-9.03 ppm for Sn, and 0.17-0.68 ppm for Pb. Those values are below the permitted range (less than 150 ppm for Sn and 2 ppm for Pb).

This study was investigated for the purpose of obtaining basic data which can be applied to processing of canned sea mussel using tomato paste. Shell were washed, and then steamed and shucked. Sea mussel meat was prepared with ratio of sea mussel 90g, tomato paste sauce 65g(tomato paste 42%, gum guar 1.0%, salt 2.0%, starch syrup 2.0%, cooking wine 1%, water 52%). The sea mussel meats were packed with vacuum seamer in 301-3 can, and then sterilized for various F0 value(F0 8-12 min.) in a steam system retort at $118^{\circ}C$. The factors such as pH, VBN, amino-N, total amino acid, free amino acid, chemical composition, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable bacterial count of the canned sea mussel produced with various sterilization condition(F0 8-12 min.) were measured. The same element was also measured during preservation. The results showed that the product sterilized at F0 8 min. and preserved for 90 days were the most desirable.

There is a limitation to estimate vitamin $B_{12}$ intake due to a lack of data on vitamin $B_{12}$ content in many Korean foods. In this study, vitamin $B_{12}$ content was determined in some seaweeds, fish, and shellfish and their product that are consumed in Korea using a modified microbioassay with Lactobacillus delbruecki ATCC 7830. Dried laver and dried seasoned and toasted laver contained very high levels of vitamin $B_{12}$ (66.8 and $55.2-71.3\;{\mu}g$/100 g, respectively. Sea lettuce and seaweed fulvescene also contained high vitamin $B_{12}$ content of 5.47-9.41 and $6.46-7.20\;{\mu}g$/100 g, respectively, whereas sea mustard and sea tangle contained low levels of vitamin $B_{12}$; vitamin $B_{12}$ was not detected in seaweed fusifome. Pacific saury, trout, sea-bass, or squid contained 12.01, 2.00, 0.49 and $2.33\;{\mu}g$ vitamin $B_{12}$/100 g, respectively. Ochellatus octopus, and naked sand lance contained 0.72-1.43 and $3.68\;{\mu}g$ vitamin $B_{12}$/100 g, respectively. Dried Alaska pollack con-tained $0.19-2.64\;{\mu}g$ vitamin $B_{12}$/100 g. Shellfish such as little neck clam and small ark shellfish contained high levels of vitamin $B_{12}$ of $30.5-40.5\;{\mu}g$/100 g, and mussel and abalone contained 17.71 and $7.82\;{\mu}g$/100 g, respectively. Of unique Korean traditional fermented seafood products, salt-fermented products of squid ($2.91\;{\mu}g$/100 g), clams ($34.31\;{\mu}g$/100 g), Ala-ska pollack roe ($9.98-12.02\;{\mu}g$/100 g), hairtail guts ($4.58\;{\mu}g$/100 g) or small shrimp ($0.58-1.55\;{\mu}g$/100 g), and fish sauce from anchovies ($1.52-1.78\;{\mu}g$/100 mL), sand eel ($0.22-0.24\;{\mu}g$/100 mL) or small shrimp ($0.19-0.78\;{\mu}g$/100 mL) were analyzed. A few commercial brands of flying fish roe ($0.73-1.73\;{\mu}g$/100 g), canned tuna ($0.40\;{\mu}g$/100 g), and fried fish paste ($0.25-0.69\;{\mu}g$/100 g) were also analyzed. In conclusion, vitamin $B_{12}$ content in these foods, chosen considering the Korean food culture, should contribute to improve the present vitamin $B_{12}$ food database. It may be helpful to estimate vitamin $B_{12}$ intake more correctly than before, and provide additional information for dietary education related to vitamin $B_{12}$ and meal management.
