Summary
Mineral content in tropical fruit juices was analyzed. Levels of essential minerals like copper and zinc were found, while toxic metals were very low, ensuring safety within legal limits.
Area of Science:
- Food Science
- Environmental Chemistry
- Public Health
Background:
- Fruit juices are popular beverages in tropical regions.
- Assessing mineral content is crucial for dietary intake and safety.
Purpose of the Study:
- To quantify mineral concentrations in commercially available tropical fruit juices.
- To evaluate the safety of these juices based on local legislation.
Main Methods:
- Analysis of four commercial fruit juice brands.
- Quantification of cadmium, lead, copper, zinc, aluminum, iron, chromium, manganese, and molybdenum using analytical techniques.
Main Results:
- Copper, zinc, aluminum, iron, and manganese were detected at varying levels.
- Cadmium, lead, and chromium were found to be very low or undetectable.
- All analyzed metal concentrations were within the limits set by local legislation.
Conclusions:
- Tropical fruit juices contain essential minerals and minimal toxic metals.
- The mineral profiles are influenced by agricultural and manufacturing factors.
- The analyzed fruit juices are safe for consumption according to current regulations.
