Effect of organic acids on the formation of biogenic amines in fermented anchovy sauce comprising raw anchovy materials with different levels of freshness.

We investigated the effect of different levels of organic acids on the formation of biogenic amines in anchovy fish sauce. Fish sauce samples were prepared with fresh anchovies used immediately after being caught (F), and anchovies left at ambient temperature for 4 h (4 h), 18 h (18 h), or 24 h (24 h). Anchovies from each of the four groups were mixed with salt at a 4:1 ratio and then fermented at ambient temperature for varying periods of time.

Concentrations and Risk Assessment of Heavy Metals in Tissues of Walleye Pollock () Captured from the Northeastern Coast of Korea.

All heavy metals, except Hg, were well accumulated in liver compared with muscle and gonads. Estimated daily intakes of heavy metals were within 2% of the provisional maximum tolerable daily intakes, Hazard quotients of heavy metals were less than 1.0.

Freshness Evaluation in Chub Mackerel () Using Near-Infrared Spectroscopy Determination of the Cadaverine Content.

We analyzed the volatile basic nitrogen content, pH, total viable cell count, and biogenic amine contents in chub mackerel () stored at 5 and 25°C to examine changes in freshness. Among the various parameters, we found the volatile basic nitrogen content had the highest correlation with cadaverine content ( = 0.72 to 0.

Estimating Postmortem Interval by Bioluminescent Determination of ATP Content in the Muscle of Olive Flounder ( Paralichthys olivaceus).

ATP content was determined by a luminometer for PMI of sliced raw fish within 24 h. Comparison of RLU by luminometer and HPLC-based ATP content had a high correlation of r = 0.96 to 0.

Sea Squirt (Halocynthia roretzi) Hydrolysates Induce Apoptosis in Human Colon Cancer HT-29 Cells through Activation of Reactive Oxygen Species.

Recent evidence provides that seafood has a lot of health benefits due to its unique bioactive compounds. Sea squirt is widely cultured and consumed as a foodstuff in Korea; however, seldom reports with reference to bioactivities are available until now. In this study, edible part of sea squirt was hydrolyzed by pepsin and its hydrolysates was evaluated for anticancer effect on human colon cancer HT-29 cells.

Concentrations of trace metals in tissues of Chionoecetes crabs (Chionoecetes japonicus and Chionoecetes opilio) caught from the East/Japan Sea waters and potential risk assessment.

The concentrations of trace metals (As, Cd, Co, Cu, Fe, Hg, Pb, and Zn) were measured in muscle and hepatopancreas of two Chionoecetes crabs (Chionoecetes japonicus and C. opilio) caught from the East/Japan Sea (EJS) in order to assess the potential health risk by the consumption of deep sea crabs. The highest metal concentrations in muscle and hepatopancreas were As and Fe, respectively, while the lowest metal concentration in two tissues was Pb.
