MicroLub engineers a protein-water microgel that mimics fat's mouthfeel — and raises $10M to scale it

What Happened

UK food-tech MicroLub, a University of Leeds spinout, closed a £7.5M ($10M) round led by Northern Gritstone to scale its microgel technology, which coats protein scaffolds with polysaccharides so they release water on chewing and mimic the creamy mouthfeel of fat. The company says the approach cuts fat and calories in foods like cheese, yogurt and baked goods by up to 75% while cutting molecular friction 20-fold versus water and 10-fold versus rival fat replacers.

Why It Matters

Fat replacement technologies have historically traded taste for calorie reduction — MicroLub's friction data (20x lower than water) suggests it's engineering the physical lubrication mechanism itself rather than just substituting ingredients, which is why it's landing $10M in the GLP-1-driven high-protein, low-calorie wave.

20 times less friction than water, engineered to feel like fat.

FET's Takeaway

The friction-based approach is the interesting engineering detail here: instead of chasing fat's flavor-carrying role, MicroLub is targeting its tribological function — the same lubricity problem that dairy and ice cream formulators wrestle with when they strip fat and end up with a chalky, icy mouthfeel.
