  • Sprout ginseng paste were prepared with pine nut, dry oyster and dry shrimp to examine the antioxidant properties(total polyphenols, total flavonoids, and electron donating ability) and sensory test(attribute difference and acceptance). Sprout ginseng paste were measured based on color value, pH, viscosity, total bacteria cell numbers for 0 and 20 days at $4^{\circ}C$. The higher total polyphenol and total flavonoid content of sprout ginseng paste added with pine nuts, dry oyster, and dry shrimp were higher antioxidant capacity. DPPH radical scavenging activity was increased from 52.2% (SGP0) to 79.5.0 % with SGP5. The attribute test results reveal that the color intensity, bitter taste, and oily taste were decreased in SGP3 to SGP6. Taste, flavor, and coarseness did not show significant difference in SGP0 to SGP6. Thickness and After taste were increased in SGP4 to SGP6. The preference test results reveal that the appearance, flavor, and texture level did not show significant difference in SGP0 to SGP6. Taste and overall preference were increased in SGP4 to SGP6. L value, pH, decrease while a value and b value show no change in sprout ginseng paste with pine nut, dry oyster and dry shrimp. Total cell number was not detected during storage.

  • This study was attempted to process low-sodium salt fermented small shrimp as substitutes for traditional high-sodium salt fermented one which has widely been favored and consumed in Korea. Low-salt fermented small shrimp was prepared with $4\%$ sodium chloride and $4\%$ potassium chloride, and various additives such as $0.5\%$ lactic acid, $6\%$ sorbitol and $4\%$ ethylalcohol extract of red pepper as preservatives and flavor enhancers. And the changes of taste compounds, volatile compounds and fatty acid composition in low-salt fermented small shrimp were analyzed and compared with those of conventional $20\%$ sodium salt fermented one during the fermentation of 120 days at $25{\pm}3^{\circ}C$. The most favorable taste for fermented small shrimp were reached at 60 days of fermentation. Judging from sensory evaluation, little difference of taste was detected between the low-salt fermented small shrimp and high-sodium salt fermented one. The principal taste compounds in fermented small shrimp were free amino acids, and betaine and nucleotides and their related compounds played an assistant role. The major amino acids in fermented small shrimp were glutamic acid, leucine, proline, glycine, lysine and aspartic acid. The major fatty acids in fermented small shrimp samples were 16:0, 20:5, 22:6, 16:1 and 18:1, and unsaturated fatty acids decreased slightly while saturated fatty acids increased during fermentation. At 60 days of fermentation 8 kinds of volatile fatty acids (acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid, valeric acid, isocarproic acid, carproic acid), 6 kinds of carbonyl compounds (ethanal, propanal, 2-methylpropanal, 3-methylbutanal, pentanal, 2-methylpentanal), and 3 kinds of volatile amines (methylamine, trimethylamine, isopropylamine) were identified.

  • Volatile flavor compounds of sauces made from shrimps, crabs or lobsters were analyzed by the combination of canister system, gas chromatography(GC) and mass selective detector(MSD). Of 72 total volatile compounds from 4 kinds of sauces, 45 compounds were identified from shrimp sauce(SS). Ten alkanes, 5 ketones, 3 aldehydes were obtained from SS. Especially, 3-methyl-2-butanone, 2-pentanamine, isobutane, 3-methyl-2-butanol, carbon disulfide and dimethyl sulfide were predominant compounds in SS. In crab sauce(CS), there were 18 compounds identified, including 4 alcohols, 4 alkanes, 3 aldehydes, 2 ketones, acid and amine. 2-Methoxy ethanol, trimethyloxirane and 3-buten-1-ol were special volatile compounds in CC. Volatile compounds from lobster head sauce(LHS) or lobster shell sauce(LSS) were 16 or 18 kinds respectively. The major volatile compounds of LHS were formic acid, 1-propanethiol, $\beta$-pinene and allyl sulfide, and those of LSS were acids, pentane, 3-methyl-1-butanol and 2,4-dimethyl-3-pentanone. It was thought that the volatile compounds identified from sauces as well as shrimps, crabs or lobsters might come from wine, onions, bay leaves or celery used as minor ingredients.

  • This study compared aroma compositions and sensory aroma attributes of raw and cooked Tenebrio molitor larvae (mealworms). Main sensory aroma attributes of raw mealworms were strong wet-soil-like, and less-intense oily, shrimp-like and sweet-corn-like. Quantitatively, the major aroma components of raw mealworms were hydrocarbons and aldehydes. As cooking proceeded, sweet-corn-like, roasted, and fried-oil-like sensory attributes were increasingly perceived with steaming, roasting, and frying, respectively. Some pyrazines, pyrrolidines, and carbonyls increased or appeared in roasted and fried mealworms. Partial least squares regression also showed differences in raw and cooked mealworms based on aroma components and their sensory attributes. Unlike raw mealworms, steamed mealworms had a relatively strong sweet-corn-like aroma attribute, which was related to 2,4,6-trimethyl-heptane, 2,4-dimethyl-dodecane, and 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one. In comparison, roasted and fried mealworms exhibited roasted, shrimp-like, and fried-oil-like aroma attributes, which were associated with intermediates of the Maillard reaction and lipid oxidation, such as pyrazines, alcohols, and aldehydes. This result during thermal reactions was very similar to those of meat and/or seafood. The use of mealworms as a savory-type flavor enhancer can be expected.

  • The aim of this study is to evaluate the availability of salted and fermented fish (SFF) including salted and fermented anchovy (SFA) and shrimp (SFS) as a marinade of beef jerky. In curing solutions, half (SFA 1 and SFS 1) or whole (SFA 2 and SFS 2) salt-water was replaced with SFF juices. Higher water activity ($a_w$) was found in the beef jerky cured with SFFs than the control (C) (p<0.05). The SFFs had the effect of causing a decrease in hardness and an increase in cohesiveness (p<0.05). Among the treatment samples, springiness was the highest in SFA2 and SFS2 (p<0.05) and the lowest values of Warner-Bratzler shear force were found in SFA1 and SFA2 (p<0.05). The SFFs also had the effect of increasing the flavor of the sensory properties; however, color measurements from both the instrumental surface color ($L^*$, $a^*$, $b^*$, chroma, and hue angle) and color of sensory evaluation were decreased by addition of SFFs (p<0.05). Therefore, we conclude the SFFs can improve the texture and sensory properties of the beef jerky. In particular, the SFS is a good ingredient for the curing solution. However, studies are still needed on improving the $a_w$, pH, and surface color of the beef jerky to apply the SFFs for making beef jerky.

  • 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.
