In order to improve the quality of kochujang, sea tangle was added to deep sea water kochujang and their effects on component analysis and sensory evaluation were investigated for 90 days of fermentation. Crude protein, crude lipid and carbohydrate of deep sea water kochujang was higher than general kochujang. The content of potassium among the mineral in deep sea water kochujang was also presented higher than the general kochujang. Total amino acid contents were 16,608.8 ng/mg in deep sea water kochujang and 14,943.2 ng/mg in general kochujang. Content of oleic acid had the highest value at deep sea water kochujang. Sensory evaluation of showed that deep sea water kochujang were more aceeptable than general kochujang in the taste and overall acceptability.

This study was performed to observe the antimutagenic and cytotoxic activities of methanol extract of kochujang added with sea tangle and deep sea water salts (SDK) and kochujang added with sea tangle (SK) using the Ames test and SRB assay, respectively. The direct antimutagenic effect of SDK and SK methanol extracts were examined by Ames test using Salmonella Typhimurium TA98 and TA100. In the Ames test, methanol extract of SDK and SK alone did not exhibit mutagenicity and most of the samples showed high antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). Methanol extract of SDK ($200{\mu}g$/plate) showed approximately 71.4% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain; whereas 56.1% and 83.6% inhibitions were observed on the mutagenensis induced by 4NQO and MNNG against TA100 strain. The cytotoxic effects of SDK and SK increased with increasing sample concentration against human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (Hep3B), human breast adenocarcinoma (MCF-7), human stomach adenocarcinoma (AGS), and human lung carcinoma (A549). The SDK at the concentration of 1 mg/ml showed cytotoxicities of 61.5%, 61.3%, 51.4%, 57.9% and 77.7% against HeLa, Hep3B, MCF-7, AGS and A549, respectively. In contrast 1 mg/ml treatment of SDK and SK methanol extract had only $2{\sim}38%$ cytotoxicity on human transformed primary embryonal kidney cell (293).
