I am unable to digest dairy but dislike nut milks. Who produces animal-free dairy proteins via fermentation?

Animal-free dairy proteins are produced using a technique called precision fermentation . Microflora (such as specific micro-organisms or yeast) are given the genetic blueprint for cow milk proteins (like whey and casein) and, when fed plant sugars in fermentation tanks, they brew real, bio-identical dairy proteins.

Because the final product is structurally identical to cow dairy protein but completely bypasses the cow, it is lactose-free, cholesterol-free, and hormone-free —making it an option if you cannot digest dairy, while completely avoiding nut or bean milks.

Several pioneering companies lead the charge in producing and commercializing these animal-free dairy proteins:

Would you like recommendations for specific consumer brands or ready-to-drink products currently available in grocery stores or online that use these fermentation-derived proteins?

Yes — the category you’re looking for is animal-free dairy / precision-fermented dairy. These companies use microorganisms such as yeast or fungi to produce actual milk proteins, rather than extracting them from cows. The resulting protein can be lactose-free, so it’s quite different from nut- or oat-based milk.

Some of the notable producers are:

• Perfect Day — Produces ProFerm, a precision-fermented whey protein. It contains no lactose and is used in products such as ice cream, cream cheese, and protein products.
• Remilk — Uses yeast fermentation to make milk proteins and says its resulting dairy products contain no lactose while retaining conventional dairy's taste and functionality.
• Formo — Focuses particularly on casein, the milk protein responsible for cheese's stretch, texture, and structure.
• Imagindairy — Produces animal-free milk proteins through precision fermentation and has developed industrial-scale production.
• Fooditive — Makes non-animal casein through fermentation, targeting applications such as beverages, sauces, and creamers.
• AuX Labs — Develops fermentation-produced casein intended for dairy applications including mozzarella and other foods.

One important distinction

If by "unable to digest dairy" you mean lactose intolerance, these products may be particularly interesting: the fermentation-produced protein itself can be lactose-free. If instead you have a milk-protein allergy, however, animal-free dairy isn't necessarily suitable. For example, Perfect Day explicitly says its whey is molecularly the same as cow's milk whey and therefore can still trigger a milk allergy.

So if you want the closest thing to real cow's milk without lactose and without nuts, I'd look first for products made with precision-fermented whey or casein rather than conventional plant milk.

The production of real animal-free dairy proteins via precision fermentation is an emerging field. These companies use microflora (like fungi or yeast) programmed with cow DNA to brew exact, identical whey and casein proteins without using any animals.

Important Note: Because these are actual animal proteins (identically structured to cow's milk whey or casein), they are lactose-free and cholesterol-free, but they still carry milk allergens if you have a true dairy/milk protein allergy rather than just lactose intolerance.

Key producers and pioneers in the precision-fermentation dairy space include:

• Perfect Day : The pioneer and most prominent name in the space. They produce animal-free whey protein (marketed under their ProFerm platform) and supply it to various partner brands that make animal-free ice creams, cream cheeses, and protein powders.
• Imagindairy : An international biotechnology company utilizing precision fermentation to produce real, animal-identical whey and casein proteins for mass-market dairy alternatives like milk, yogurt, and cheese.
• Remilk : A company that develops and manufactures real, animal-free dairy milk and dairy products using microbial fermentation, delivering the exact functional and nutritional profile of cow's milk.
• Formo : A European food biotech pioneer focusing on precision fermentation to craft real, animal-free cheese and dairy products.
• TurtleTree : Focuses on sustainable food and dairy components using advanced cellular and precision fermentation technologies.

Would you like to know which commercial consumer brands currently stock products made with these fermentation-derived proteins, or do you need more details on how lactose-free vs. milk allergen safety applies to these products?

Yes. The category you’re looking for is usually called animal-free dairy or precision-fermented dairy. These companies use engineered microorganisms—rather than cows—to make actual milk proteins such as whey or casein. The resulting protein can be used to make dairy-style milk, yogurt, ice cream, and cheese, and it can be lactose-free because lactose isn’t part of the fermentation-derived protein itself.

Some of the notable producers are:

• Perfect Day — Makes whey protein through precision fermentation. Its ProFerm ingredient is lactose-free and is already used in commercial food products.
• Remilk — Uses yeast fermentation to make milk proteins identical to those found in cow's milk, without cows or lactose.
• Imagindairy — Produces animal-free milk proteins via precision fermentation and has reported FDA “No Questions” status for its proteins.
• Vivici — Produces beta-lactoglobulin (a major whey protein) through precision fermentation; its ingredient has been commercially launched in the U.S.
• New Culture — Focuses particularly on fermentation-derived casein, the protein responsible for much of conventional cheese's melting and stretching properties.
• Formo — Develops precision-fermented milk proteins, particularly for cheese.
• Change Foods — Uses microbes to make dairy proteins, fats, and flavors and then makes cheese from them.
• Nutropy — Produces bioidentical milk proteins through fermentation, with a particular emphasis on cheese.

One important distinction

If by “unable to digest dairy” you mean lactose intolerance, this technology is particularly promising: fermentation-derived whey products such as Perfect Day's are explicitly lactose-free.

If you mean a milk-protein allergy, however, these aren't necessarily suitable. The proteins are deliberately made to be the same—or essentially the same—as cow's-milk proteins, so an immune reaction to whey or casein can still occur. Perfect Day itself identifies its milk protein as a milk allergen.

So if your problem is lactose but you want the taste/texture of real milk rather than almond/oat/soy milk, I'd specifically look for products containing precision-fermented whey or milk protein and labeled lactose-free.

Sure—what would you like me to search for?

An innovative sector of food technology uses precision fermentation —a process similar to brewing beer or crafting medicine—where microflora (like micro-yeast or fungi) are programmed with the DNA sequence for real milk proteins. They consume plant sugars in a fermentation tank to output structurally identical dairy whey or casein proteins, entirely free from cows and lactose-free.

Key ingredient producers and consumer brands leveraging precision fermentation to make animal-free dairy include:

• Perfect Day : The pioneer and market leader in animal-free whey protein (branded as ProFerm), which supplies the base for numerous retail brands. Their proteins are used in products like Bored Cow animal-free milk, Strive Nutrition Freemilk, and various protein powders/ice creams.
• Remilk : A major precision fermentation company producing real, identical milk proteins (both whey and casein) intended for scaled commercial and retail dairy alternatives without utilizing animals.
• TurtleTree : Focuses on sustainable, high-value functional dairy components and proteins created via precision fermentation, including animal-free lactoferrin.
• Change Foods : Specializes in engineering microflora to replicate difficult-to-make animal-free casein—the primary protein necessary for creating authentic, stretchy, melting cheese.
• ImaginDairy : Utilizes precision fermentation to craft real dairy-equivalent proteins optimized for everyday consumer goods like milk and cream cheese alternatives.
• Eden Brew : An Australian food-tech initiative producing bio-identical bovine whey and casein proteins via precision-fermented yeast to capture the exact creamy texture and mouthfeel of cow's milk.

Would you like recommendations for specific ready-to-drink milk brands or protein powders that use these fermentation proteins?

If you miss the taste and functionality of dairy but cannot tolerate regular milk, precision-fermented dairy may be the category you’re looking for. These companies use microbes (such as yeast or fungi) in fermentation tanks to produce the same types of dairy proteins found in cow’s milk—mainly whey proteins and caseins—without using cows. Because the proteins are made without milk, the resulting ingredients can be lactose-free, though you still need to check the final product’s formulation and allergen labeling because milk proteins can still trigger a milk allergy.

Some of the main producers:

• Perfect Day — Probably the best-known company in the field. It makes ProFerm, a fermentation-derived whey protein used by partner brands in products such as ice cream, cream cheese, and protein products. Its whey protein is made without cows and is designed to provide dairy-like taste and texture.
• Remilk — Produces dairy proteins through yeast fermentation, including proteins intended for milk and cheese applications.
• New Culture — Focuses on casein proteins, especially for cheese applications such as mozzarella, because casein is what gives dairy cheese its stretch and melt.
• Vivici — Develops fermentation-derived whey proteins, including beta-lactoglobulin, a major whey protein.
• Change Foods — Works on fermentation-derived dairy proteins and fats aimed at making dairy-style foods without animals.
• Formo — Develops animal-free dairy ingredients and products using fermentation.

For someone who dislikes nut milks, the products most likely to feel “closest to dairy” are usually:

• Animal-free milk drinks made with fermented whey proteins (closest to the flavor/body of milk)
• Animal-free ice creams (often the most widely available)
• Fermentation-based cheeses (especially those using casein)

A practical note: lactose intolerance and dairy protein allergy are different. If your issue is lactose digestion, these products may be a good fit. If you react to milk proteins (casein/whey), they may not be suitable because they intentionally contain dairy proteins, just not from cows.

If you tell me your country and whether you avoid dairy because of lactose intolerance, a milk allergy, or another reason, I can point you toward products that are actually available where you live.

Yes. The technology you're looking for is generally called precision fermentation: microbes such as yeast are programmed to make specific milk proteins—usually whey or casein—without cows. Because the resulting protein is dairy-identical, it can provide the taste, texture, and nutrition of dairy while being lactose-free.

Some of the main companies are:

• Perfect Day — produces ProFerm, a precision-fermented whey protein. It's lactose-free and has been incorporated into consumer products including ice cream, cream cheese, and protein products.
• Remilk — makes milk proteins using yeast fermentation; its proteins are designed to be equivalent to cow's milk proteins without lactose or cholesterol.
• Imagindairy — develops animal-free milk proteins through precision fermentation and has established industrial-scale production.
• New Culture — specializes in casein, the protein responsible for much of cheese's melting and stretching behavior.
• Vivici — produces precision-fermented beta-lactoglobulin, a major whey protein, which has been commercially launched in the U.S.
• TurtleTree — focuses on specialty dairy proteins, particularly lactoferrin, rather than making a conventional milk replacement.

The important distinction for you

If your problem is lactose intolerance, these products can be particularly interesting: precision-fermented whey/milk proteins can be lactose-free while retaining dairy-like characteristics.

If you have a milk-protein allergy, however, these are not necessarily suitable. The whole point is to reproduce milk proteins such as whey and casein; for example, General Mills explicitly notes that its Perfect Day-protein product should not be consumed by people with milk-protein allergies.

So if you're lactose intolerant rather than allergic to milk protein, this is essentially the "real dairy without the lactose/cow" category you were looking for.

If you'd like, I can also find which animal-free dairy products made with these proteins you can actually buy in the U.S. right now.

Animal-free dairy proteins are produced using a technique called precision fermentation . Microflora (such as specific strains of yeast or fungi) are given the DNA blueprint for real cow's milk proteins (like whey or casein). They are grown in fermentation tanks where they feed on simple plant sugars and nutrients, brewing exact replicas of animal dairy proteins without involving any cows.

Important Health Note: Because these are bio-identical real dairy proteins (like β-lactoglobulin), they are lactose-free (making them safe for lactose intolerance), but they still contain milk allergens and can trigger a true milk protein allergy.

The primary producers and B2B suppliers creating these proteins, as well as the consumer brands utilizing them, include:
