Non-Targeted Metabolomics Analysis Reveals Metabolite Profiles Change During Whey Fermentation with Kluyveromyces marxianus

Scientists fermented whey (a dairy byproduct) using a special yeast called Kluyveromyces marxianus to create a nutrient-rich food. Using advanced analysis, they found that fermentation breaks down large proteins and fats into smaller, more beneficial compounds including amino acids and omega-3 fatty acids. The fermented whey showed significant increases in health-promoting substances that could help reduce inflammation, prevent disease, and improve overall nutrition.

Stage-Specific Lipidomes of Gastrodia elata Extracellular Vesicles Modulate Fungal Symbiosis

Researchers studied how a special orchid called Gastrodia elata communicates with its fungal partner Armillaria. They found that tiny fat-like packages called extracellular vesicles carry specific molecules that help the orchid and fungus work together. These special molecules, including compounds like 7,8-dehydroastaxanthin, are most abundant when the orchid is actively absorbing nutrients from the fungus.

Exploring Pijuayo (Bactris gasipaes) Pulp and Peel Flours as Fat Replacers in Burgers: A Multivariate Study on Physicochemical and Sensory Traits

Researchers tested using pijuayo flour from an Amazon fruit to replace animal fat in beef burgers. Burgers with 25% less animal fat tasted better and had better texture than regular burgers, possibly because pijuayo adds natural flavoring compounds and has healthy unsaturated fats. Most consumers preferred these reduced-fat burgers, suggesting pijuayo could be a practical way to make meat products healthier without sacrificing taste.
