Elemental analysis of hazelnut kernels and shells by spark source mass spectrometry
Zeitschrift Fur Lebensmittel-Untersuchung Und -Forschung
|April 1, 1985
Summary
This study analyzed Turkish hazelnut varieties using spark-source mass spectrometry (SSMS), determining 35 elements. Results revealed varying concentrations of nontrace, trace, and ultratrace elements in both kernels and shells.
Area of Science:
- Agricultural Science
- Analytical Chemistry
- Food Science
Background:
- Turkey is a major global producer of hazelnuts.
- Understanding the elemental composition of hazelnuts is crucial for nutritional and agricultural insights.
- Varietal differences can influence mineral content.
Purpose of the Study:
- To quantify the elemental profile of three hazelnut varieties cultivated in Turkey.
- To compare the distribution of elements (nontrace, trace, ultratrace) in hazelnut kernels and shells.
Main Methods:
- Spark-source mass spectrometry (SSMS) was employed for elemental analysis.
- Samples from Corylus avellana var. pontica, C. maxima mill., and Corylus colurna var. glandulifera were analyzed.
- A comprehensive elemental analysis was performed on both kernel and shell fractions.
Main Results:
- A total of 35 elements were identified and quantified across all samples.
- Nontrace elements ranged from 3-5 per sample.
- Trace elements were found in amounts of 9-13, while 17-20 elements were in ultratrace quantities.
Conclusions:
- The elemental composition of Turkish hazelnut varieties is diverse, with a significant presence of ultratrace elements.
- SSMS provides a robust method for detailed elemental profiling of agricultural products like hazelnuts.
- Further research can explore the bioavailability and nutritional significance of these identified elements.
