Seaweed Protein Hydrolyzates: A Valuable Source of Short- and Medium-Chain Peptides with Multifunctional Properties

mycolabadmin

Scientists found that an invasive seaweed species can be converted into health-promoting peptides (small protein fragments) that may help control blood pressure and blood sugar levels. The study identified hundreds of these peptides and tested their effectiveness against enzymes involved in hypertension and diabetes. The peptides showed promise as natural ingredients for functional foods designed to prevent metabolic diseases while also addressing the environmental problem of harmful seaweed blooms.

Amylase-assisted extraction alters nutritional and physicochemical properties of polysaccharides and saponins isolated from Ganoderma spp

mycolabadmin

Researchers studied how enzyme treatment improves extraction of beneficial compounds from reishi mushrooms. They found that using amylase enzyme significantly increased the amounts of healthy polysaccharides and saponins recovered, especially from cultivated black reishi canopies. These extracted compounds work as natural emulsifiers comparable to lecithin and remain stable even at very high temperatures, making them promising ingredients for functional foods and health products.

Astragalus Shiitake—A Novel Functional Food with High Polysaccharide Content and Anti-Proliferative Activity in a Colorectal Carcinoma Cell Line

mycolabadmin

Scientists developed a new type of Shiitake mushroom by growing it on a special substrate enriched with Astragalus root. This novel mushroom contains significantly more beneficial polysaccharides than regular Shiitake. When tested against colorectal cancer cells, extracts from this mushroom showed strong cancer-fighting properties, with the ultrasound extraction method being most effective. This research suggests Astragalus Shiitake could become a powerful functional food for cancer prevention and treatment.
