본 연구는 국내 유통 조미건어포 27건 중 프로피온산, 안식향산, 소브산 함량을 분석하였다. 식품의약품안전처 식품공전의 분석 방법으로 GC-FID를 이용하여 프로피온산을 분석하였고 HPLC-DAD를 이용하여 안식향산과 소브산을 분석하였다. 그 결과 총 27건 중 프로피온산은 16건(검출률 59%), 안식향산은 불검출, 소브산은 7건(검출률 26%)이 검출되었다. 조미건어포에서 프로피온산은 ND-125.10 mg/kg의 농도로 검출이 되었으며 이는 미생물 최소저해농도 이하의 수치로 보존 효과를 나타낼 수 없는 농도로 보여 의도적으로 첨가되지는 않았을 것으로 사료된다. 또한, 소브산의 경우 소르빈산 칼륨이 표기된 시료에서만 검출되었으며 표기된 시료 8건 중 7건에서만 검출이 되었다. 소브산 검출 시료의 경우 658.18 mg/kg의 농도까지 검출이 되었으며, 이는 그 사용 기준에 적합한 수치였다. 본 연구는 향후 조미건어포에 대한 안전 관리를 위한 기초자료로 사용될 수 있을 것으로 사료된다.

In order to enhance suitable processing methods of imported Pacific saury, Cololabis saira, storage stability of seasoned-dried Pacific saury (imported product) treated with liquid smoke (T2 product) was compared with a control (C, seasoning only) and T1 (treatment of 0.05% BHT instead of liquid smoke). The histamine contents of 3 seasoned-dried products were within a stable range (9.08 ~ 12.08 mg/100 g) during storage. The water activities of all products were in the 0.698 ~ 0.755 range. The viable cell count of T2 was lower than those of C and T1 during storage. The change in color values of C, T1 and T2 were not significant with increasing storage period. The results of the sensory evaluation during storage showed that the shelf-life of T2 was extended to 60 days, while those of C and T1 were limited to up to 45 days.

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.
