Heimioporus sp. (Pelawan mushroom) as source of nutrition and antioxidant

Abstract Edible mushrooms are nutrient-dense, being low in calories yet rich in fiber, protein, vitamins, minerals, and bioactive compounds. The Pelawan mushroom (Heimioporus sp.), an edible variety native to Indonesia, specifically Bangka Belitung, has remained largely unexplored as a bioactive resource. This study aimed to investigate the proximate composition, mineral and vitamin content, and antioxidant potential of Pelawan mushrooms. Samples were collected from Belitung Island, Indonesia, during the rainy season in April 2024. Proximate analysis revealed that Pelawan mushrooms are low in fat but high in protein, fiber, and vitamin A, along with an abundance of essential minerals and vitamins. Extraction using solvents such as n-hexane, ethyl acetate, methanol, and water yielded 3.15 %, 1.26 %, 15.82 %, and 19.11 %, respectively.
