Objective:
To analyze the contents of Ca, K, Na, Mg, Fe, Zn, Cu and Mn in 33 kinds of marine products, such as fish, shrimp, crab, shellfish and mollusk.
Methods:
The national standard GB 5009. 268-2016 Determination of multi elements in foods was used for determination. The correlation between multi elements was statistically analyzed.
Results:
The highest level of Ca was found in clam(510. 2 mg/100 g edible), K in mackerel(444. 4 mg/100 g edible), Na in clam(487. 6 mg/100 g edible), Mg in conch(132. 7 mg/100 g edible). The highest level of Fe and Mn was in conch(37. 35 and 2. 6 mg/100 g edible). The highest level of Zn and Cu was in oyster(15. 92 and 8. 58 mg/100 g edible). The correlation analysis showed that Mn-Ca was highly correlated in fish and shrimp(r=0. 9438 and 0. 8585, P < 0. 05), while Cu-Mg, Cu-Zn, Zn-Na were highly correlated in shellfish(r=-0. 9102, 0. 8501 and 0. 8428, P < 0. 05).
Conclusion:
There are rich mineral elements in different seafood, which can provide reference for the reasonable diet of residents.
