Summary
This research examined ways to verify the authenticity of powdered mushroom supplements using smell-based testing methods. The scientists compared traditional human smell tests with electronic sensors and chemical analysis to tell different mushroom species apart. This work is important for ensuring that consumers get genuine mushroom products.
Impacts on everyday life:
– Helps protect consumers from fraudulent mushroom supplements
– Ensures quality control for mushroom-based health products
– Supports development of reliable testing methods for food authenticity
– Contributes to safer natural supplement options
– Enables better regulation of mushroom-based products
Background
Cultivated mushrooms are well-known nutrient inputs for a balanced diet and some species are appreciated for their medicinal properties. Recently, novel foods and nutraceuticals based on dehydrated and freeze-dried mushroom powder have been entering the market. The food industry requires fast and reliable tools to prevent fraud in these products.
Objective
To validate the use of different methodologies (electronic nose, sensory panel and GC-MS) to discriminate the olfactory profile of nutritional products based on freeze-dried powders obtained from different cultivated mushroom species: Agaricus bisporus sp. bisporus (white button), Agaricus bisporus sp. brunnescens (portobello), Lentinula edodes (shiitake) and Grifola frondosa (maitake).
Results
The sensory panel and electronic nose successfully differentiated between different mushroom species but could not distinguish between varieties of the same species (A. bisporus varieties). GC-MS analysis revealed distinct volatile compound profiles for each species, with compounds like 1-hexenol, hexanal, and 3-octanone being most abundant in button mushrooms, butanal-3-methyl in shiitake, and 3-octanone and hexanal in maitake.
Conclusion
The electronic nose showed analytical utility comparable to classical sensory testing but with greater speed for evaluating freeze-dried mushrooms. The techniques employed can effectively differentiate between common button mushrooms and medicinal species like maitake or shiitake, making them useful tools for preventing fraud in novel food and nutraceutical products based on cultivated mushrooms.
