Perfect Day is the top pick for someone who can’t digest dairy but dislikes nut milks: its fermentation-made whey is used in consumer lactose-free products (e.g., Bored Cow, Breyers/Unilever) to deliver creamy, nut-free milk alternatives. If you need cheese that melts and stretches, New Culture, Change Foods, or focus on fermentation-derived casein for cheese makers, though those are more B2B-focused.
Best when you want a ready-to-use, lactose-free, nut-free milk alternative: Perfect Day makes fermentation whey widely used in ice creams, milks and powders to recreate creamy dairy texture.
Best when your priority is cheese-like melt and stretch: New Culture produces fermentation-derived casein tailored for stretchy, melty cheese, but its focus is on supplying cheese makers rather than shelf-stable drinks.

Imagindairy Using Precision Fermentation to Create Animal-Free Dairy Proteins – The Spoonhttps://thespoon.tech/imagindairy-using-precision-fermentation-to-create-animal-free-dairy-proteins/
Yes. The category you’re looking for is usually called precision-fermented dairy or animal-free dairy. These companies use microorganisms such as yeast or fungi to make proteins that are molecularly equivalent or very similar to the proteins found in cow’s milk—without using cows.
A few of the notable producers are:
Perfect Day — Produces precision-fermented whey protein, including beta-lactoglobulin. Its ProFerm ingredient is lactose-free and is supplied to food companies for products such as ice cream, protein products and other dairy alternatives.
Remilk — Makes animal-free milk proteins, particularly whey proteins, through fermentation.
If by “unable to digest dairy” you mean lactose intolerance, these products can be particularly interesting: the protein is made without cow's milk, and products made with fermentation-derived whey/casein can be formulated without lactose. Perfect Day, for example, specifically describes its protein as containing no lactose.
But if you have an allergy to milk proteins (casein or whey), animal-free dairy protein is not necessarily suitable. The whole point is to reproduce the dairy proteins, so your immune system may still recognize them.
If you tell me whether your issue is lactose intolerance, milk-protein allergy, or simply that dairy makes you feel bad, I can give you a list of actual consumer products you can buy in the U.S. that use these proteins, rather than just the ingredient companies.
If you want real dairy taste, functionality, and complete proteins without using a single cow (and without touching nut-based beverages), precision fermentation is exactly what you are looking for.
Companies in this space use microflora (like micro-organisms or yeast/fungi) programmed with the genetic blueprint for cow's milk protein. They "brew" identical whey or casein proteins in fermentation tanks. Because the end product is chemically identical to animal dairy protein, it whips, melts, and tastes like real milk—but it is entirely lactose-free and animal-free.
The primary innovators and producers creating these animal-free dairy proteins include:
Perfect Day : The absolute pioneer and market leader in this space. They don't just sell their own consumer items; they supply their signature animal-free whey protein (branded as ProFerm ) to a massive roster of major food and beverage giants. Brands using Perfect Day's protein to make milk, ice cream, cream cheese, and sports powders include Bored Cow (animal-free milk), Brave Robot (ice cream), Myprotein (Non-Animal Whey powder), and lines from partners like Nestlé, Mars , and Bel Group (makers of Nurishh Incredible Dairy).[4]
Remilk : An international precision-fermentation powerhouse that creates real, dairy-identical milk proteins (whey and casein alternatives) free of lactose, cholesterol, and hormones. They partner with traditional dairy companies and commercial food producers to scale up cow-free milk, yogurt, and cheese alternatives globally.
Imagindairy : A food-tech startup utilizing precision fermentation to produce real-deal milk proteins from microflora. They focus heavily on creating fluid milk and broader dairy alternatives that possess the exact functional characteristics and mouthfeel of cow's milk.
Change Foods : A startup that specifically targets casein —the complex protein responsible for the stretch, melt, and structure of real cheese. While many fermentation companies started with whey, Change Foods focuses on recreating animal-free casein so authentic, stretchy fermented cheeses can hit the market.
TurtleTree : Known for using precision fermentation to produce high-value, bioactive functional dairy components—such as lactoferrin (an immune-boosting protein naturally found in milk)—completely free of animals.
Note on purchasing: When shopping, look for labels that specifically say "animal-free dairy" or "made with real dairy protein, not from cows." Because these products contain actual whey/milk protein, they are not suitable for those with a true milk protein allergy (though they are completely safe for those with standard lactose intolerance).
Would you like recommendations for specific brands and products (like milk, protein powders, or ice cream) that use these fermented proteins, or are you looking for options available in a particular country?
The industry standard and pioneer for animal-free dairy proteins produced via precision fermentation is Perfect Day.
Instead of using animals, Perfect Day introduces the genetic blueprint for whey or casein into microflora (like micro-fungi/yeast), which are then fermented with plant sugars in a brewing process similar to crafting craft beer. The resulting proteins are molecularly identical to those found in cow's milk, completely lactose-free, and free of animal inputs, but they possess the exact functional, taste, and structural properties of real dairy.
Several major ingredient suppliers and consumer brands utilize or develop these fermentation-derived dairy proteins:
Perfect Day (B2B Ingredient Provider) : They supply their animal-free whey protein (ProFerm ) to massive global food conglomerates and specialty brands rather than selling a single direct consumer line. Partners include Nestlé (which has piloted animal-free chocolate and white beverages) and Mars.
Brave Robot : A popular consumer brand (originally launched via Perfect Day’s incubator, The Urgent Company) that makes animal-free, lactose-free ice cream using real dairy proteins brewed entirely without cows.
Myprotein : Uses Perfect Day's animal-free whey in specialized sports nutrition lines like their Whey Forward protein powder.
Change Foods : A separate food-tech startup focusing on precision fermentation to produce bio-identical dairy proteins and fats specifically engineered to make animal-free real cheeses, yogurts, and butter.
New Culture : Another emerging innovator utilizing precision fermentation to craft animal-free, stretchy, meltable real mozzarella cheese intended for food service and pizza.
The EVERY Company : While they focus primarily on animal-free egg proteins (like ovalbumin) rather than milk via precision fermentation, they operate in the exact same technological ecosystem.
Note on Allergies: Because these products contain real, bio-identical whey or casein proteins, individuals with a true milk/dairy protein allergy (rather than just lactose intolerance) still need to exercise caution, though they are entirely safe for those who are strictly lactose-intolerant or avoiding animal farming.
Are you looking for a specific type of product (like milk to pour in coffee, cheese, or protein powder), or a store locator for brands near you?
Yes. The category you’re looking for is animal-free dairy made with precision fermentation: microbes such as yeast or fungi are programmed to produce the same dairy proteins found in cow’s milk, without using cows. So the resulting products can behave much more like conventional dairy than almond/oat/soy milk.
Some of the leading companies are:
Perfect Day — produces whey protein, including its ProFerm ingredient. It contains no lactose, although products made with it aren't automatically suitable for people with milk-protein allergies.
Formo — focuses heavily on casein, the protein responsible for much of cheese's stretch, melt and structure. Its technology is particularly interesting if you miss real cheese.
Imagindairy — produces animal-free milk proteins and has achieved industrial-scale manufacturing; it has also received an FDA “No Questions” letter for its animal-free milk proteins.
Remilk — uses fermentation to make milk proteins, including beta-lactoglobulin.
New Culture — develops fermentation-derived casein specifically aimed at making convincing mozzarella and other dairy products.
Vivici — develops fermentation-derived dairy proteins for applications such as protein drinks, powders and bars.
Standing Ovation — specializes in casein and is working toward large-scale production.
Eden Brew — produces cow-free casein and received U.S. GRAS clearance in 2026.
One important distinction for you
If by “unable to digest dairy” you mean lactose intolerance, precision-fermented dairy could be a particularly good fit. For example, Perfect Day's whey protein itself contains no lactose.
If you have a cow's-milk protein allergy, however, these products are generally not a solution: the goal is to make the actual milk proteins (such as whey or casein), just without the cow.
If you tell me whether your problem is lactose intolerance, milk-protein sensitivity/allergy, or simply that conventional dairy makes you feel bad, I can point you toward the animal-free milks, ice creams, cheeses, or protein powders you can actually buy today.
Several biotechnology companies produce animal-free dairy proteins using precision fermentation, creating real whey and casein proteins without using cows. Because these products are made via microbial fermentation, the resulting proteins are entirely lactose-free, cholesterol-free, and hormone-free , making them safe for people with lactose intolerance (though they contain real dairy proteins, so they are not safe for a true milk allergy).
Perfect Day : The pioneer in the space, they use microflora to produce identical animal-free whey protein. Their ingredients are used in various partner brands for ice cream, protein powders, and milk alternatives.
Remilk : Produces real, animal-free milk proteins via microbial fermentation that are completely free of lactose, cholesterol, and antibiotics.
Formo : A European food biotech company focusing on precision fermentation to create sustainable, animal-free dairy cheeses and protein bases.
Better Dairy : A UK-based startup utilizing precision fermentation to manufacture the full spectrum of dairy products without the cow.
Change Foods : Focuses on recreating real, stretchy animal-free cheese products using microbial fermentation to produce traditional dairy proteins.

Yes — the category you’re looking for is animal-free dairy made with precision fermentation. These companies use engineered microorganisms to make actual milk proteins, rather than using almonds, oats, soy, etc.
Some of the notable producers are:
Perfect Day — Makes whey protein through precision fermentation. Its ProFerm whey contains no lactose, and Perfect Day says it is used in products such as ice cream, cream cheese, baked goods, and nutrition products.
Remilk — Uses yeast fermentation to produce milk proteins such as beta-lactoglobulin, which can be formulated into dairy products without cows and without lactose.
Formo — Focuses particularly on casein, the milk protein responsible for much of cheese's stretch, texture, and functionality.
Imagindairy — Produces animal-free milk proteins through precision fermentation and has developed industrial-scale production. Its proteins are described as animal-, cholesterol-, and lactose-free.
New Culture — Has focused on precision-fermented casein for mozzarella and other cheese applications.
Nutropy — Produces bioidentical milk proteins through engineered microorganisms and fermentation, targeting cheese, yogurt, cream, and other applications.
Vivici — Produces precision-fermented dairy proteins including lactoferrin; its lactoferrin entered the U.S. market in 2026.
The important distinction for you
If by “unable to digest dairy” you mean lactose intolerance, these products can be particularly interesting because the fermentation companies are making the protein rather than extracting it from cow's milk, so the resulting ingredient can be lactose-free. Perfect Day, Remilk, and Imagindairy explicitly describe their proteins/products as lactose-free.
If, however, you have a milk-protein allergy, that's different: these proteins are deliberately designed to be molecularly the same or very similar to cow's milk proteins, so they may not be suitable.
If you tell me whether your issue is lactose intolerance, milk-protein sensitivity/allergy, or just general difficulty digesting dairy, I can also give you a list of actual animal-free dairy products you can buy in the U.S. right now.
Yes. What you’re looking for is usually called precision-fermented dairy or animal-free dairy protein. These companies use microorganisms in fermentation tanks to make proteins that are the same—or functionally equivalent—to milk proteins, without cows.
Some of the leading producers are:
perfectday.com — makes animal-free whey protein through fermentation. Its ProFerm protein contains no lactose, so it can be used in milk, ice cream, yogurt, cream cheese, and protein products.
formo.bio — specializes in casein, the major protein responsible for cheese's stretch, melt and texture. Its casein is produced using precision fermentation.
imagindairy.com — produces animal-free milk proteins using precision fermentation and has developed industrial-scale production capacity.
Remilk — develops animal-free milk proteins, including whey-type proteins, through fermentation.
New Culture — focuses on precision-fermented casein, particularly for making animal-free cheese with conventional dairy-like properties.
Vivici — develops precision-fermented dairy proteins, including proteins intended for shakes, powders and other nutrition products.
Standing Ovation — a French company developing precision-fermented casein; it has been working toward industrial-scale production.
Fooditive — produces non-animal casein through fermentation and describes it as lactose-free and suitable for dairy-style applications.
One important distinction
If by "unable to digest dairy" you mean lactose intolerance, these products can be particularly interesting because the protein itself doesn't require cow's milk—and products made with Perfect Day's whey, for example, can be lactose-free.
If you mean a milk-protein allergy, however, be more careful: animal-free whey or casein is still a milk protein. Being made without an animal doesn't necessarily make it safe for someone allergic to milk proteins.
If you tell me whether your issue is lactose intolerance, milk-protein sensitivity/allergy, or just difficulty digesting conventional dairy, I can narrow this down to actual products you can buy in the U.S.
Perfect Day is the pioneer and leading commercial producer of animal-free dairy proteins created via precision fermentation.
The process—known as precision fermentation—uses microflora (such as micro-flora/fungi) programmed with specific DNA sequences to produce real, bio-identical milk proteins (whey and casein) in fermentation tanks, completely bypassing the cow. Because these are true dairy proteins rather than plant extracts, they function, melt, and taste like conventional dairy, but they are entirely animal-free and lactose-free (though they do contain milk allergens like whey, if you have a true dairy allergy rather than just lactose intolerance).

If you dislike nut milks but cannot tolerate regular dairy, animal-free dairy proteins made through precision fermentation are probably the closest match to the taste and texture of conventional dairy. They are not plant milks: companies use microbes (often yeast or fungi) programmed to produce specific milk proteins such as whey protein (beta-lactoglobulin) or casein, then use those proteins to make milk, ice cream, yogurt, cheese, and protein products.
Companies working in this space include:
Perfect Day — One of the earliest and most commercialized companies. It makes animal-free whey proteins through precision fermentation, which have been used in products such as ice creams, cream cheeses, and protein powders.
Remilk — Produces milk proteins (including beta-lactoglobulin) using fermentation and supplies ingredients intended for dairy-style products like milk, yogurt, ice cream, and cream cheese.
New Culture — Focuses on fermentation-made casein, especially for dairy-style cheeses such as mozzarella.
Vivici — Develops fermentation-derived beta-lactoglobulin whey protein ingredients.
Imagindairy — Works on fermentation-produced dairy proteins for use in dairy alternatives.
Formo — A European company developing animal-free dairy products using precision fermentation.
A few things to know if your issue is lactose intolerance:
These products are generally designed to be lactose-free, because they contain the dairy proteins but not milk sugars.
If you have a milk protein allergy (casein or whey allergy), these may not be suitable, because the goal is to make the same milk proteins found in cow’s milk.
Availability varies a lot by country and product category; many companies sell ingredients to food brands rather than directly selling cartons of “milk.”
If you want something to drink rather than a yogurt/ice cream/protein product, the brands and products available near you depend heavily on location. I can help find currently available animal-free dairy products in the U.S. (or your region).
Perfect Day — Produces precision-fermented whey protein, including beta-lactoglobulin. Its ProFerm ingredient is lactose-free and is supplied to food companies for products such as ice cream, protein products and other dairy alternatives.
Remilk — Makes animal-free milk proteins, particularly whey proteins, through fermentation.
