1Faculty of Chinese Pharmacy, Beijing College of Traditional Chinese Medicine.
Summary
Processing muli significantly alters the content of 34 essential trace elements. This study quantifies these changes using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) for nutritional analysis.
Area of Science:
- Food Science
- Analytical Chemistry
- Nutritional Science
Background:
- Muli, a type of fruit, is a source of essential trace elements.
- Understanding the impact of processing on nutrient content is crucial for food quality and safety.
Purpose of the Study:
- To determine and compare the concentrations of 34 trace elements in muli samples.
- To investigate the changes in trace element composition before and after processing.
Main Methods:
- Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) was employed for precise elemental analysis.
- Five distinct samples of muli were analyzed in their raw and processed states.
Main Results:
- Significant variations in the content of all 34 analyzed trace elements were observed after processing.
- Specific elements showed marked increases or decreases, indicating differential effects of the processing methods.
Conclusions:
- Food processing techniques demonstrably alter the trace element profile of muli.
- Further research is needed to understand the bioavailability and nutritional implications of these elemental changes.
