Determination of heavy metals and other mineral elements in food

There are known more than 50 kinds of elements contained in food, except for the four elements of C, H, O, and N that constitute water and organic matter, the other elements are collectively referred to as mineral elements
.

Determining the content of heavy metals and other mineral elements in food has guiding significance for evaluating the nutritional value of food, developing and producing fortified foods; it is beneficial to the improvement of food processing technology and the improvement of food quality
.

This project mainly introduces the determination of Ca, P, Pb, Cu, Fe, Cd, As, and Hg
.

1.
The effect of macro elements such as calcium and phosphorus on the human body

It refers to seven kinds of major elements of mineral elements Ca, Mg, P, Na, K, Cl, S and the like
.

Calcium is the main component of human bones and teeth.
Calcium can also promote blood coagulation and play an important role in maintaining the normal contraction of the heart and neuromuscular excitability
.

Second, the determination method of major elements in food

The determination methods of major elements in food include titration, colorimetry, spectrophotometry, atomic absorption spectrophotometry and so on
