To develop a seasoned laver from cooking oyster effluent (C-COE), this study optimized the C-COE concentration, roasting temperature and time using response surface methodology (RSM). The optimal C-COE concentration, roasting temperature and time for producing seasoned laver from C-COE were 31.0%, 182.2℃ and 21.1 sec, respectively. The proximate composition of the seasoned laver prepared with C-COE under the conditions was 5.2% moisture, 37.4% crude protein, 8.2% crude lipid, 11.1% ash, 38.1% carbohydrate. The water activity of the prototype seasoned laver was 0.038. The prototype had stronger taste and flavor intensities than a commercial product. There was no difference (P>0.05) in the Hunter color value between the prototype and the commercial product. The peroxide (POV) and acid values (AV) of the prototype were 6.0 meq/kg and 1.4 mg KOH/g, respectively, which are considered acceptable. The results suggest that the seasoned laver with C-COE developed can be industrialized.

This study assessed the biological and physicochemical hazards involved in establishing a hazard analysis critical control point (HACCP) for canned seasoned Broughton's ribbed ark Scapharca broughtonii and examined the critical control points (CCPs) in the field. Following the basic principles of the HACCP system, the hazard-evaluation procedures were enacted during the production of canned seasoned Broughton's ribbed ark after field investigation of a seafood product company in Korea. CCPs were determined using canned seasoned Broughton's ribbed ark with the corresponding control measures. The HACCP system was applied to each step in processing the product. The results indicated that inspection of raw materials, filling, sterilization, and alien substance detection were the most important CCPs. These results can be used to prevent and control food safety problems in the production of canned seasoned Broughton's ribbed ark.

Shrimp in seasoned soy sauce (S-SS) is a popular seafood product in Korea, but it could be potentially hazardous; thus, this study was conducted to investigate its safety. Commercial S-SS were collected and analyzed for pH, volatile basic nitrogen (VBN), hygenic indicator microorganisms (viable cell count, coliforms, and Escherichia coli), food poisoning bacteria (Staphylococcus aureus, Vibrio parahaemolyticus, and Listeria monocytogenes), preservatives (dehydroacetic acid, sorbic acid, benzoic acid, and its salt, parahydroxybenzoate), tar colorants, and sensory properties. Domestic and foreign standards were also investigated for S-SS. Commercial S-SS ranged from to 6.2-7.3 for pH, 13.7-39.1 mg/100 g for VBN, and 4.6-6.9 log CFU/g for viable cells. The coliforms and E. coli of commercial S-SS were from ND to 3.4 log CFU/g and negative, respectively. Food poisoning bacteria, preservatives, and tar colorants were not detected in commercial S-SS. Only the coliform count and presence of E. coli in commercial S-SS exceeded the set standards of vietnam, while all items were within domestic and foreign standards.
