Precision-fermentation dairy proteins involve the genetic engineering of microbes to produce milk proteins such as whey and casein. These proteins are then harvested from fermentation processes and used to create dairy products without the need for cows.
This technology addresses the environmental impact of traditional dairy farming, such as greenhouse gas emissions and land use, while also providing a sustainable alternative for consumers seeking animal-free dairy options.
Microbes, typically yeast or bacteria, are genetically modified to express and secrete specific milk proteins into their environment. The engineered microbes are cultured in large-scale fermenters under controlled conditions. The secreted proteins are then harvested, purified, and processed into dairy ingredients that can be used in food products.
The manufacturing process involves genetic engineering, fermentation, and purification steps. The microbes are engineered to produce specific proteins, which are then grown in large fermenters before being harvested and purified.
The initial build process includes selecting the appropriate host microbe, designing the genetic modifications necessary for protein production, optimizing growth conditions in the fermenter, and developing downstream processing techniques for purification and formulation into dairy ingredients.
