[Study of determination method of trace elements in white jade snail]

Area of Science:

• Analytical Chemistry
• Food Science
• Nutritional Science

Context:

• Trace element analysis is crucial for understanding the nutritional value of edible organisms.
• The white jade snail ( a potential food source) requires detailed nutritional profiling.
• Accurate determination of essential minerals is vital for food safety and quality assessment.

Purpose:

• To quantify six key trace elements (Ca, Mg, Fe, Zn, Cu, Co) in white jade snails.
• To validate the accuracy and reliability of Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) and Atomic Absorption Spectroscopy (AAS) for this analysis.
• To assess the nutritional potential of white jade snails as a food source.

Summary:

• Six trace elements (calcium, magnesium, iron, zinc, copper, cobalt) were measured in white jade snails using ICP-AES and AAS with high-pressure digestion.
• Both analytical methods yielded comparable results, indicating high accuracy with recoveries ranging from 92.4% to 103.0% and relative standard deviations below 2.98%.
• The study confirms that white jade snails are a rich source of beneficial trace elements.

Impact:

• Highlights white jade snails as a highly nutritious and valuable 'green food' option.
• Provides reliable analytical methodology for trace element determination in similar biological matrices.
• Supports the potential for incorporating white jade snails into diets for enhanced mineral intake.
