Summary
A new high-pressure digestion method accurately determines trace elements in beans using ICP-AES. This rapid, sensitive, and eco-friendly technique matches traditional wet methods, offering reliable bean nutrient analysis.
Area of Science:
- Agricultural Chemistry
- Analytical Chemistry
- Food Science
Context:
- Accurate quantification of trace elements in food is crucial for nutritional assessment and safety.
- Traditional wet digestion methods can be time-consuming and involve hazardous chemicals.
- Developing rapid, sensitive, and environmentally friendly analytical techniques is an ongoing need in food analysis.
Purpose:
- To evaluate a high-pressure nitrifying pot method for determining multiple trace elements in beans.
- To compare the efficacy of this new method with the conventional wet method.
- To assess the method's sensitivity, accuracy, speed, and environmental impact.
Summary:
- Trace elements (Ca, Mg, Mn, Sr, Fe, Co, Ni, Se, Ba) in beans were analyzed using inductively coupled plasma atomic emission spectrometry (ICP-AES) with a high-pressure nitrifying pot digestion method.
- Results from the high-pressure digestion method showed no significant difference compared to the traditional wet method.
- The high-pressure method is characterized as simple, rapid, highly sensitive, accurate, capable of multi-element determination, and produces minimal environmental pollution, with a recovery rate of 96.8%-102% and a relative standard deviation of 3.35%.
Impact:
- Provides a validated, efficient, and greener alternative for trace element analysis in beans.
- Facilitates more accessible and widespread nutritional profiling of legumes.
- Contributes to improved food quality control and safety standards through advanced analytical chemistry techniques.
