Frequently Asked Questions


What is Protina?​

Protina is a sustainable plant-based protein that is produced from spent grains. Spent grains are malted barley grains used in the early stages of making beer. These grains are a rich source of protein that have been under-appreciated up till now.

How do you convert spent grain into protein?

Our patented process uses a combination of green/eco-friendly chemical and enzymatic treatments to convert spent grain into a protein. The process used to produce Protina requires no additional farmland, energy, or water to produce – thus making Protina truly the most sustainable protein in the world!

What are some culinary applications of Protina?

Protina can be used to replace any existing pea- or soy-based protein food products. Of course, Protina can also be used to replace meat in new and revolutionary plant-based meat replacement products!

What does Protina taste like?

Protina has a neutral taste profile, making it useful in any sweet, savory, and salty product formulations.

Is Protina genetically modified?

Protina is produced from spent grains sourced from Canadian barley. There are no GMOs found in Canada’s grain or feed system.

Are there any allergy concerns with Protina?

All plant-based and meat-based proteins can trigger allergic reactions for certain individuals with sensitivities. However, Protina is free of peanuts and tree nuts.

Is Protina vegan?

Yes! Protina is 100% vegan! All our processes and products are free of ingredients that are on PETA’s list of animal-derived ingredients. This means they are naturally free of dairy, eggs, honey, and other animal-derived components (such as gelatin).

Environmental and Economic Sustainability

What are the environmental advantages of using Protina?

As mentioned above, our products are 100% vegan and do not contain any animal-derived components such as meat, poultry, fish, shellfish, dairy, eggs, or honey. Our process also does not further strain the food supply chain, as it does not require extra arable land, water, or energy.

What are the advantages of using Protina over other plant-based meat analogues?

Pea-based proteins production processes often suffer from scalability issues, thus making it difficult securing long-term supply. Similarly, soybean expansion is not sustainable and is an underlying driver of deforestation in regions like South America. Protina, on the other hand, is sourced from an existing supply chain and can be scaled up to produce large amounts of protein rapidly. Furthermore, given that our supply chains are local, our production process is also not sensitive to export commodity price fluctuations.

Where does Terra Bio source its spent grain?

Our spent grain is sourced from local breweries and will be commercially produced right here in Canada!
