AI Technical Summary

Technical Problem

Existing iron supplements have shortcomings in terms of stability, absorption efficiency, and bioavailability. In particular, they are easily oxidized in the gastrointestinal environment, which reduces the bioavailability of iron. Furthermore, traditional methods are costly or have gastrointestinal irritation side effects.

Method used

The product utilizes a complex formed by whey protein and tannic acid, which binds to ferrous ions in a non-covalent manner, enhancing their stability and antioxidant properties. This whey protein-tannic acid-ferrous ion complex ensures the stability and absorption efficiency of ferrous ions in the digestive tract.

Benefits of technology

It significantly improves the bioavailability of iron, reduces gastrointestinal oxidative side effects, maintains the divalent activity of iron, and has a simple preparation method, making it suitable for iron supplementation in food and beverages to meet the needs of specific populations.
