Bioactive Properties of Mushroom (Agaricus bisporus) Stipe Extracts

摘要: The antibacterial activity and total phenolic (TP) content of Agaricus bisporus stipes were assessed using solvent water extracts to determine its bioactivity. Extraction methods included accelerated extraction (ASE) hot followed by membrane concentration. Water extract from ASE had the highest TP 1.08 gallic acid equivalents (GAE)/g dry weight (DW) ethanol at 0.61 mg GAE/g DW 0.11 mg for acetone. Acetone inhibited Escherichia coli Staphylococcus aureus less than 50%; E. coli 61.9% S. aureus 56.6%; 78.6% 65.4%. concentrated mushroom was 17 mg GAE in 100 mL. Membrane a higher percentage inhibition on E. coli. Overall, results promising further application stipe as functional food additive. Practical Applications Mushrooms are known their health benefits have been identified good source nutrients. highly perishable nature mushrooms warrants processing preservation minimize losses along supply chain. This study explores possibility adding value stipes, by-product fresh industry. indicate content, potential these ingredients provides valuable information scientific community industries developing novel meet market demand natural additives.
