Mycoprotein (fermented fungal protein): Protein, Calories & Full Nutrition Breakdown

Why Mycoprotein (fermented fungal protein) shows up in protein-forward diets

This is the ingredient behind the 2026 'mycelium protein' TikTok wave — it's produced by fermenting a fungus (Fusarium venenatum) in large vats, similar in concept to how beer yeast is grown, and it carries a genuinely complete amino acid profile unlike most single-source plant proteins.

Serving-size math

A 100g portion delivers 15.0g of protein and roughly 110 calories. Scaled per 100 calories, that works out to 13.64g of protein — useful for comparing against other foods on a calorie-matched basis rather than a weight-matched one.

Prep tip

It absorbs marinades unusually well because of its fibrous structure — don't over-marinate past the package's suggested time or the texture turns mushy.
