Canada Approves Genetically Modified Yeast Food Additive

On September 12, 2024, Health Canada issued an official document approving Sourvisiae®, a genetically modified saccharomyces cerevisiae (i.e., brewer's yeast) preparation for use as a food additive.

In 2023, Health Canada received an application for a license to market Sourvisiae®, a genetically modified saccharomyces cerevisiae (i.e., brewer's yeast) preparation, for food production. Sourvisiae® was developed to replace other commercial yeasts during beer fermentation to produce alcohol and give beer its characteristic sour taste through the production of lactic acid.

In order to assess the suitability of the yeast preparation for sale as a food additive in Canada, Health Canada scientists conducted an exhaustive scientific assessment to ensure its safety for consumption.

After a rigorous evaluation, Health Canada has confirmed that the genetic modification of this yeast strain does not pose a greater health risk than other yeast strains available on the market. In addition, the Health Ministry also concluded that the yeast strain does not cause allergic reactions and that its use in food does not raise any nutritional concerns.
