Bromatological composition and qualitative chromatographic profiles of Lentinula edodes and Pleurotus ostreatus

Abstract

Introduction: Edible mushrooms provide nutrients and metabolites of food interest; however, their composition depends on the species and cultivation and analytical conditions. Objective: To describe the bromatological composition and qualitative chromatographic profiles of Lentinula edodes and Pleurotus ostreatus. Methods: One sample from a single batch of each species was analyzed. Moisture, dry matter, crude protein, fat, ash, and carbohydrates were determined in technical duplicate and expressed as mean ± standard deviation. Extracts intended for the analysis of phenols, terpenes, and flavonoids were evaluated by thin-layer chromatography under UV light at 254 and 365 nm. Results: L. edodes showed 91.00 ± 1.41% moisture, 4.65 ± 0.49% protein, and 2.35 ± 0.00% carbohydrates; P. ostreatus showed 92.69 ± 4.71%, 4.35 ± 0.66%, and 0.96 ± 0.00%, respectively. Chromatographic signals and fluorescent zones compatible with the metabolite groups studied were observed in both species. Conclusion: The samples showed high moisture content, numerically similar protein values, and distinguishable qualitative chromatographic profiles.
