This study developed a natural seasoning (NS) and characterized its food components. Hydrolysate from Alaska Pollock Theragra chalcogramma heads and sea tangle Laminaria japonica byproduct were obtained by incubating them with Neutrase for 4 h. NS was prepared by mixing sorbitol 2%, salt 2%, ginger powder 0.04%, garlic powder 0.2%, onion powder 0.2% and inosine monophosphate (IMP) 0.1% based on concentrated hydrolysates from Alaska pollock head and sea tangle byproduct before vaccum filtering. The proximate composition of NS was 82.7% moisture, 9.0% crude protein, and 5.1% ash. It had a higher crude protein content than commercial anchovy sauce (CS), it was lower in moisture and ash. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and angiotensin-I converting enzyme (ACE) inhibiting activity of NS were 90.1% and 88.9%, respectively, which were superior to those of CS. The free amino acid content and total taste value of NS were 1,626.0 mg/100 mL and 165.86, respectively, which were higher than those of CS. According to the results of taste value, the major free amino acids were glutamic acid and aspartic acid. In the sensory evaluation, the color and taste of NS were superior to those of CS.

This study evaluated the physicochemical and sensory characteristics of teriyaki sauce added with samultang. Soluble solid content and salinity of teriyaki sauce groups added with samultang were lower than the control. The pH of the samples ranged from $4.16{\pm}0.12{\sim}4.26{\pm}0.12$, a difference that was not significant. Regarding viscosity, as the amount of added samultang was increased, the viscosity of teriyaki sauce decreased. Teriyaki sauce with samultang showed $25.72{\pm}1.52{\sim}32.94{\pm}0.94(%)$ of DPPH radical scavenging activity; free radical scavenging activity of teriyaki sauce significantly increased with an increase samultang. According to the result of sensory evaluation, overall-acceptability was $6.43{\pm}1.96$, which is approximately 10% higher than the other groups. Taken together, the results of this study suggest that samultang is a beneficial ingredient for increasing consumer acceptability and the functionality of teriyaki sauce.

Nutritional quality of accelerated salt-fermented anchovy sauce using shrimp processing byproduct as fermenting aids was characterized and compared with commercial anchovy sauce. Four types of sauces were fermented with 0 and $10\%$ addition of shrimp byproducts ($24{\pm}2^{\circ}C$, for 270 days), and 20 and $30\%$ addition of those ($24{\pm}2^{\circ}C$, for 180 days), respectively. Extractive nitrogen content (1,431 to 1,569 mg/100g) of anchovy sauces increased as additional ratios of shrimp byproduct increased. According to the results of ommission test, the taste of all anchovy sauces was influenced by the content of free amino acids, such as mainly glutamic acid and aspartic acid. Regardless of additional ratios of shrimp byproducts, all sauces were similar in total amino acid content ($9,848\~10,324$ mg/100 g), which were 2 times higher compared to that of the commercial sauce. Proline, valine and histidine contents of sauces tend to decrease as the additional ratios of shrimp byproducts increased, whereas methionine, isoleucine, leucine, phenylalanine and lysine contents increased. Increase of some amino acids and mineral content of sauces by increasing of additional ratios was due to release from shrimp byproducts. Sensory evaluation showed that scores of color, flavor and taste of the sauce added with $20\%$ shrimp byproducts_were significantly higher than those of other sauces (p<0.05). In the useful utilization aspects of seafood processing byproducts, shrimp byproducts were good resource for accelerated fermentation and nutritional improvement in preparation of fish sauce.

For the use of skipjack tuna cooking drip (STC) as a source of functional seasoning, the STC was hydrolyzed with various commercial enzymes, such as Alcalase, Flavourzyme, Neutrase and Protamex, and its hydrolysate was also investigated on the food component characteristics. The hydrolysate incubated with Alcalase for 30 min (HA30) showed 56.8% for angiotensin I converting enzyme (ACE) inhibitory activity and 1.18 for antioxidative activity, which were high or similar compared to the other enzymatic hydrolysates. There were no differences in ACE inhibitory activity and antioxidative activity among HA30, two-step enzymatic hydrolysates, and ultrafilterates (molecular weight cut off, 10 kDa). The HA30 was very stable on the digestive enzymes, such as chymotrypsin, pepsin, trypsin according to the TCA (trichloroacetic acid) soluble index. The results suggested that skipjack tuna cooking drip could be used as a source for preparing functional seasoning sauce.

Fish sauce is a traditional Korean fermented seafood and has been used as a condiment since long time ago. Northern sand lance sauce was manufactured with koji, enzyme, and squid viscera of fermentation accelerating agents, and ripened at $15^{\circ}C$. Moisture contents of all samples decreased gradually as fermentation progressed. Crude protein contents increased rapidly up to 1 month-fermentation and then increased slightly up to 5 month. Northern sand lance sauce with squid viscera was the highest in the contents of protein and lipid. The ash content increased gradually during the fermentation periods, while pHs decreased. TMA contents increased up to 3 month-ripening and then decreased slightly. Amino nitrogen content of Northern sand lance sauce with squid viscera increased as fermentation progressed and was the highest among all samples. VBN contents increased up to 5 month-ripening and that of Northern sand lance sauce with squid viscera was the higher than others.

This study was carried out to prepare spaghetti sauce with adductor muscle of pearl oyster (SSAM) and to compare with commercial spaghetti sauce (CSS). From the results of organic acid, pH, hunter color value and sensory evaluation, the optimal addition ratio of adductor muscle of pearl oyster was 11% based for preparing SSAM and reasonable $F_0$ value was about 4 min for keeping storage of SSAM. The proximate composition of SSAM was 69.8% for moisture, 3.7% for protein, 4.2% for crude lipid and 3.4% for crude ash. SSAM was superior in sensory flavor and texture to CSS. There was, however, no significant difference (p<0.05) in sensory color between CSS and SSAM. The total amino acid content (3,033.4 mg/100 g) of SSAM was higher than that (2,305.7 mg/100 g) of CSS and the major amino acids were aspartic acid, glutamic acid, leucine and lysine. Calcium and phosphorus contents in SSAM were 48.5 mg/100 g and 27.1 mg/100 g, respectively. Calcium level based on phosphorous was 1.78, which was a good ratio for absorbing calcium. The free amino acid content and taste value of SSAM were 989.4 mg/100 g and 141.04 mg/100 g, respectively These results suggested that the major taste active compounds among free amino acid were glutamic acid and aspartic acid.
