Comparative Analysis of Freeze-Dried Pleurotus ostreatus Mushroom Powders on Probiotic and Harmful Bacteria and Its Bioactive Compounds

Researchers studied oyster mushrooms processed in different ways to understand their health benefits. The study found that cooked oyster mushroom powders can kill harmful bacteria and promote the growth of beneficial gut bacteria. These mushrooms also contain special particles called carbon nanodots that form during cooking and may enhance their health-promoting effects. The findings suggest oyster mushrooms could help maintain a healthy gut microbiota naturally.

In Vitro Prebiotic Potential of Opuntia humifusa Leaf Extract and Its Active Constituent

Researchers studied a traditional Korean plant called Opuntia humifusa to determine if it could act as a prebiotic—a food component that promotes the growth of beneficial gut bacteria. They found that leaf extracts, particularly when prepared with 60% ethanol, effectively stimulated the growth of Lactobacillus bacteria. The active ingredient was identified as a compound called isorhamnetin glycoside, which could make this plant a natural ingredient for functional foods designed to support digestive and overall health.

Heat Treatment of Reishi Medicinal Mushroom (Ganoderma lingzhi) Basidiocarp Enhanced Its β-glucan Solubility, Antioxidant Capacity and Lactogenic Properties

This study shows that heating dried Reishi mushrooms at 150°C for 20 minutes improves their health benefits. The heat treatment increases antioxidant compounds, makes the beneficial β-glucans more available, and enhances prebiotic effects that feed good gut bacteria while suppressing harmful bacteria. These findings suggest that properly heated Reishi mushroom products could be more effective as functional food ingredients without losing their medicinal properties.
