How Flour Shape the Microbes Behind Sourdough’s Sourness
Introduction: The microbial mystery behind sourdough flavor Sourdough is often praised for its complex flavor, tang, and texture. But what actually sets one loaf apart from another can begin long before the dough hits the oven. A recent study published in Microbiology Spectrum, led by researchers at North Carolina State University in Raleigh, investigates how…

The Hidden Microbes That Steer Sourdough’s Sourness: How Flour Choice Shapes Flavor
Why Flour Choice Matters for Sourdough Flavor Sourdough is loved for its tangy complexity, bubbly texture, and comforting aroma. While bakers often credit patience and hydration, recent research shines a brighter light on the invisible architects of flavor: the microbes living in the starter. A study published in Microbiology Spectrum by Heil and colleagues at…

The Hidden Microbes That Decide How Sourdough Tastes
What makes sourdough taste uniquely sour? Sourdough is more than flour, water, and time. Across bakeries and home kitchens, the tangy profile, texture, and aroma of sourdough loafs seem to depend on an invisible cast of microbial players. A recent study published in Microbiology Spectrum by Heil and researchers at North Carolina State University in…

What Foods Make You Smell More Attractive: Foods And Scent Perception
Understanding How What We Eat Affects Our Scent Our bodies aren’t just influenced by our genetic makeup and personal hygiene; what we eat can subtly shape how we smell to others. Each person has a unique scent profile, a kind of fingerprint formed by metabolism, hormones, and microbial activity on the skin. Some foods can…

Gut hydrogenase: the hidden engine behind gut hydrogen production and Crohn’s disease
Introduction: A new look at the gut’s hydrogen economy In the complex world inside our intestines, microscopic microbes carry out countless reactions that influence health. Among these, the production and management of molecular hydrogen (H₂) have long been an underappreciated piece of the puzzle. A recent multinational study published in Nature Microbiology pinpoints the primary…

Gut’s Hidden Hydrogen Engine: How a Key Enzyme Fuels Healthy Guts and Falters in Crohn’s Disease
Unveiling the gut’s hydrogen engine Scientists have long known that the human gut is a bustling metabolic reactor. Carbohydrates are fermented by trillions of microbes, yielding energy, beneficial short-chain fatty acids, and a spectrum of gases. Among these gases, molecular hydrogen (H₂) plays a surprising and crucial role. Rather than being a mere byproduct, H₂…
