Scientific analysis methods
- Analytic testing method for polysaccharides: Sulfuric Acid Anthrone Method
- Analytic testing method for specific known beta-glucanes (like Lentinan or maitake D-fraction): HPLC (High Performance Liquid Chromatography)
- Analytic testing method for specific branching type beta-glucanes (1-3, 1-4, 1-6): NMR (Nuclear Magnetic Resonance Spectroscopy)
It is very laborious to determine the quality of a mushroom-extract by means of analysis. If it can be guaranteed, that the extraction is derived from good raw materials and conducted according to the rules of the art and the extracts are not elongated, then the final product will be of best quality.
Therefore, eventually the qualification of the supplier as well as the direct inspection on-site into the production processes are to be considered more highly than the subsequent control by means of the above described partially very elaborate analysis, which always only capture partial aspects of the extracts, but never the whole benefit.
