Mushroom and cereal β-D-glucan solid state NMR and FTIR datasets

Summary

This research provides a large database of spectroscopic measurements from β-D-glucans extracted from various mushrooms and cereal grains. The data includes detailed chemical fingerprints obtained through two analytical techniques (NMR and infrared spectroscopy) that can help researchers understand the structure and properties of these beneficial compounds. The dataset is freely available for other scientists to analyze and use for developing new methods or understanding how different mushroom and cereal sources vary in their chemical composition.

Background

β-D-glucans are important polysaccharides found in mushrooms and cereals with potential health benefits. Previous research has focused on limited chemical shift ranges in NMR spectroscopy. This study provides comprehensive spectroscopic datasets to enable broader analysis of these compounds.

Objective

To provide original measurement data from solid state NMR and FTIR spectroscopy of β-D-glucan extracts from identified mushroom and cereal samples. The goal is to enable different researchers to examine multiple carbon regions and employ alternative processing parameters for analysis.

Results

The database contains original Free Induction Decay and processed spectra from multiple mushroom species and cereal samples in Topspin format. FTIR data are provided as excel-compatible frequency/absorbance pairs. Variable contact time and non-quaternary suppression experiments are included for detailed structural analysis.

Conclusion

This comprehensive spectroscopic dataset enables detailed examination of β-D-glucan structures from natural mushrooms and cereals beyond the previously analyzed C1 region. The freely accessible data in Mendeley Data repository allows researchers to conduct further structural analysis and develop improved processing methodologies.
