Delivery of Phenolic Compounds, Peptides and β-Glucan to the Gastrointestinal Tract by Incorporating Dietary Fibre-Rich Mushrooms into Sorghum Biscuits

This study examined how adding mushroom powder to sorghum biscuits affects the availability of beneficial compounds in our digestive system. Using laboratory simulations of stomach and intestinal digestion, researchers found that mushroom-enriched biscuits released more phenolic compounds with antioxidant properties throughout the digestive tract. Importantly, the mushroom fiber helped carry beneficial β-glucan compounds to the colon, where they can be fermented by gut bacteria to produce health-promoting compounds.

Purification and biochemical characterization of a novel thermostable protease from the oyster mushroom Pleurotus sajor-caju strain CTM10057 with industrial interest

Scientists discovered a special protein-cutting enzyme from oyster mushrooms that works exceptionally well at high temperatures and in harsh cleaning conditions. This enzyme, called SPPS, cuts through protein stains similar to how detergent enzymes work in laundry. The enzyme is more stable and efficient than commonly used commercial enzymes and can withstand organic solvents. This discovery makes it a promising candidate for improving detergent formulations and other industrial applications.

Effects of Rhizopus oligosporus-Mediated Solid-State Fermentation on the Protein Profile and α-Glucosidase Inhibitory Activity of Selenium-Biofortified Soybean Tempeh

Researchers used a fungus called Rhizopus oligosporus to make selenium-enriched tempeh, a traditional soybean food. The selenium-enriched tempeh had better protein breakdown, higher amino acid levels, and was better at controlling blood sugar than regular tempeh. This research suggests that selenium-biofortified tempeh could be a healthy functional food for people looking to manage blood sugar levels naturally.

Tenderness-related index and proteolytic enzyme response to the marination of spent hen breast by a protease extracted from Cordyceps militaris mushroom

This study examined how a protease enzyme extracted from Cordyceps militaris mushrooms can tenderize tough meat from older laying hens. When applied as a marinade at 4-6% concentration, the mushroom enzyme activated the meat’s natural tenderizing enzymes and improved texture comparable to commercial papain. The treatment also enhanced the savory umami taste while limiting damage to connective tissue, offering a natural alternative for improving affordable spent hen meat.
