Our take

CleanPlate review

Four ingredients: yeast protein, cacao, vanilla, monk fruit

Cosmix Fermented Yeast Protein (Indonesian Cacao) is a 500 g tub of fermented yeast protein (inactive dry yeast) with cacao powder, vanilla bean powder and monk fruit. One 38 g scoop gives about 24 g of protein. The panel prints per 100 g and per serve, and the energy per 100 g is worked out from the serve value.

CleanPlate scores it AC3. The A for nutrition reflects 62.5 g protein, 8.3 g fibre and natural iron, zinc and calcium per 100 g. The C for ingredients reflects mostly refined or industrial ingredients (led by fermented yeast protein, cacao powder and vanilla bean powder), with additives that cost points: monkfruit monk fruit extract. The 3 for risk comes mainly from sodium (355 mg per 100 g) and calories (373 kcal per 100 g).

A closer look

Does the label add up?

Fermented yeast protein (inactive dry yeast), cacao powder, vanilla bean powder and monk fruit.

Per 100 g: 373 kcal, 5.8 g fat of which 2.8 g saturated, 8.5 g sugar of which 0 g added, 8.3 g fibre, 62.5 g protein, 355 mg sodium. No ingredient has a percentage, so the yeast protein, cacao and vanilla shares are hand-estimated from the protein balance (about 78%, 18% and 2%) and the score is provisional. Energy per 100 g is not printed and is worked out from 141.7 kcal per 38 g (373 kcal). The listing shows zinc 134.9 mg, which is the sodium per serve read in the wrong row; the pack panel (zinc 7.5 mg per 100 g, sodium 355 mg per 100 g) is used. The front says 500 g and a back sticker says 1 kg; 500 g is used. Yeast protein is not in the protein-quality table, so it takes the pea isolate factor (0.85).

Ingredients to watch

  • Single isolated proteinWorth watching

    Yeast protein is an industrial extract, which is why the ingredients grade is a C.

  • Shares not declaredWorth watching

    No percentage for the yeast protein, the cacao or the vanilla.

  • SodiumWorth watching

    355 mg per 100 g, about 135 mg a scoop.

  • Short listFine

    Four ingredients with no gum, emulsifier, flavouring or preservative.

Common misconceptions

Myth: "Yeast protein is brewer's yeast"

It is an isolated protein from fermented yeast, scored as an industrial protein.

Myth: "Vanilla bean powder is a main ingredient"

It is estimated at about 2% of the powder.
