반염건 민어는 특유의 육조직, 맛 및 영양가가 우수하여 국내에서 아주 선호되고 있는 수산가공품 중의 하나이다. 본 연구에서는 전통수산가공품의 하나인 반염건 민어를 지역명품으로 개발하기 위한 기초 자료로서 시판 반염건 민어의 위생학적 특성에 대하여 살펴보았다. 시판 반염건 민어의 생균수 및 대장균은 각각 4.2~8.3 log(CFU/g) 및 18>~4.6 log(MPN/100 g)이었다. 또한 시판 반염건 민어의 수분 함량은 64.2~77.1% 범위, 염도는 2.1~9.5% 범위, 휘발성염기질소 함량은 14.1~58.1 mg/100 g 범위, 과산화물값은 19.1~107.2 meq/kg 범위였다. 이상의 반염건 민어에 대한 미생물학적 및 화학적 결과에 의하면 지역 명품 반염건 민어를 가공 및 유통하기 위해서는 반드시 적절한 품질 규격[원료는 모두 국산, 수분 함량은 65% 이하, 염도는 2~3% 범위, 휘발성염기질소 함량 50 mg% 이하, 생균수 및 대장균은 각각 6 log(CFU/g) 이하 및 음성]이 있어야 할 것으로 판단되었다.

This study investigated the sanitary characteristics of commercial salted semi-dried convict grouper Epinephelus septemfasciatus (SSD-CG) and longneck croaker Pseudotolithus typus (SSD-LC) and suggested standards for salted semi-dried fish (SSD-F), based on the domestic standards for salted mackerel (Scomber japonicus or kwamegi) and salted dried yellow corvenia (Pseudosciaena manchurica), and sanitary characteristics of commercial SSD-F. For the commercial SSD-CG and SSD-LC, respectively, the moisture content ranged from 64.6-76.1 and 65.7-77.5%, salinity from 2.7-8.2 and 1.5-4.9%, volatile basic nitrogen (VBN) from 22.1-88.2 and 13.5-87.4 mg/100 g, peroxide value (POV) from 17.2-195.0 and 28.5-190.2 mEq/kg, and viable cell counts from 6.1-8.4 and 5.4-7.2 log (CFU/g). No Escherichia coli was detected in six kinds of SSD-CG or three kinds of SSD-LC. The standard for controlling the quality of SSD-F is the moisture content (>68%), salinity (>3%), VBN content (>50 mg/100 g), POV (>60 mEq/kg), viable cell counts (>$10^6$ CFU/g), E. coli (>MPN/100 g), and others. Using the established standards, no commercial SSD-F passed. The chemical, microbial, and other results for commercial SSD-F suggest that provisions for controlling the quality of high-quality SSD-F should be established.

This study characterized the nutrition and taste of commercial salted semi-dried brown croaker Miichthys miiuy (SSD-BC). The mean crude protein content of the commercial SSD-BC was $19.8{\pm}1.7%$ (range, 17.7-23.2%), and the mean crude lipid content was $0.6{\pm}0.3%$ (range, 0.3-1.1%). The total amino acid content ranged from 17.08 to 18.56 g/100 g, except for sample code 5, which was 22.24 mg/100 g and differed significantly from the other samples. The major amino acids in the commercial SSD-BC were aspartic acid, glutamic acid, leucine, and lysine. In the commercial SSD-BC, the calcium ranged from 11.1-21.4 mg/100 g, phosphorus from 148.4-209.2 mg/100 g, and magnesium from 12.2-48.2 mg/100 g. Monoenoic acid (37.1-40.3%) was the most common fatty acid, followed by saturated acid (33.9-36.3%) and polyenoic acid (25.1-29.2%). The prominent fatty acids in the commercial SSD-BC were 16:0 (23.9-26.5%), 16:1n-7 (11.3-13.0%), 18:1n-9 (19.7-21.5%), and 22:6n-3 (6.9-10.7%). The mean trichloroacetic acidsoluble nitrogen content was 248.1 (range, 137.2-334.2) mg/100 g. The evaluation demonstrated that the commercial SSD-BC is rich in nutrition and taste.

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.
