Seriously. Solein® is a unique single-cell protein made with a fully natural fermentation process. Using just air and electricity as its primary raw materials, Solein is the most sustainable protein in the world.


Solein is not a plant nor an animal. Instead, it originates from a natural, non-modified, single-cell organism. It is nonetheless a completely natural protein, even though it is not grown traditionally.

It has been around even longer than our other foods have. Solein is protein in its most natural form.

A protein ingredient including all essential amino acids akin to soy protein, Solein can replace the protein in virtually any food.



The taste of Solein is completely neutral and as an ingredient, it is exceptionally functional – making Solein ideal for virtually every food imaginable. So it can taste like anything it is used as an ingredient for.

Dietarily, Solein is kind to all. It's 100% vegan-friendly and caters to every diet around. Doesn't matter if you're Buddhist or flexitarian – Solein can top everyone's dinner plate with no hiccups.

Cooking with Solein


Solein is 65-70 % protein, 5-8 % fat, 10-15 % dietary fibres and 3-5 % mineral nutrients. The macronutrient composition of the cells is very similar to that of dried soy or algae. Solein solves many deficiencies: it provides a source of iron, fibre, B vitamins, and vitamin A in the form of beta-carotene, which also gives Solein its distinct colour. 

While protein is found in both plant and animal-based foods, edible proteins are not all the same. They are made up of different combinations of amino acids and are characterised by the ratio of essential amino acids they have.

Solein contains all of the nine essential amino acids that are required by the human body.


Solein can be produced anywhere with air and electricity. Taking a page from nature's playbook, Solein uses the air and nutrition found in our surrounding nature. It creates protein exactly in the same way as plants do. The only difference is, Solein does it all a little more efficiently.
