Characterization and assessment of nutritional and antioxidant potential of wild shiitake (Lentinula edodes) from the North-Western Himalayas
摘要
Wild edible fungi are known for their nutritional and medicinal value, wild collections from various Himalayan areas are still underreported. This research evaluated the nutritional composition, mineral content, antioxidant activity of three wild collections of Lentinula edodes from the North-Western Himalayas in India. Pure cultures of wild specimens were maintained on Potato Dextrose Agar medium and were deposited at ICAR-Directorate of Mushroom Research (DMR) located in Solan, Himachal Pradesh, where accession numbers are provided to ensure traceability. The species identity was confirmed through ITS region sequencing and by comparing it with sequences from the GenBank database. The analysis of the proximate composition of the fruiting bodies revealed the macronutrient constituents, including carbohydrates, proteins, fats, crude protein, moisture and ash content. The mineral analysis highlighted the presence of vital elements that enhance their dietary significance. The evaluation of the antioxidant radical scavenging assay indicated slight differences among the collections. These findings present region-specific baseline information on the nutritional composition, mineral content, antioxidant capacity of wild L.edodes from the North-Western Himalayas, offering insights for future nutritional evaluations and sustainable use.
