FAQ

  • What is animal-free dairy protein?

    Perfect Day is reimagining dairy protein without cows. We’ve invented the world’s first real milk proteins made without animals, so you can enjoy the real taste, texture, and nutrition of dairy — but produced sustainably and without the downsides of factory farming, lactose, hormones, or antibiotics.

  • Why animal-free protein?

    We’re creating a new category in the market. Something that satisfies the needs of dairy lovers and plant-based fans alike. We’re taking the compromise out of the dairy aisle and restocking it with the best of both worlds — the real taste and texture of dairy, produced sustainably, without the downsides of factory farming, lactose, hormones, or antibiotics.

  • What makes Perfect Day’s dairy protein different from other “alternative” sources of protein?

    Because our animal-free dairy proteins are identical to those found in cow’s milk, they deliver the same creamy, melty, silky taste and texture of conventional dairy that plant-based alternatives just can’t match.

  • What’s the advantage of using Perfect Day dairy protein in dairy products?

    Our animal-free whey protein has the same nutritional profile and culinary functionality as whey protein from cow’s milk, but it’s vegan; free from lactose, cholesterol, and hormones; and has a smaller environmental footprint than conventional whey protein isolate. Our ingredient is ideal for providing a rich, creamy, smooth, and indulgent eating experience and excels in product applications requiring solubility, gelation, water-binding, foaming, heat stability, and emulsification.

  • How do you make animal-free dairy protein?

    We’ve developed a type of microflora that can ferment simple plant ingredients to produce the milk proteins, casein and whey, historically found in milk. We started with a natural type of microflora known to produce large amounts of pure protein for food and gave this flora a “blueprint” that allows it to ferment sugar and create real dairy protein. This is the very same blueprint, in the form of DNA, which cows use every day.
    Our protein is made using safe and proven fermentation techniques similar to how many common food components like vitamins, probiotics, enzymes, and natural flavors are made.

    Our process is much cleaner and more resource-efficient than animal farming, and it’s the cornerstone of our new approach to dairy. To learn more, check out our process page.

  • What is flora?

    Flora is an all-encompassing term that refers to a microorganism such as bacteria, yeast, or in our case, fungi. We chose to use microflora to make our proteins because they have a long history of safely making ingredients in many foods you eat today, and because microflora are particularly good at producing animal proteins.

  • Is your protein vegan?

    Yes! Flora-made dairy protein is made without the use of animals and zero compromise on taste and nutrition.

    Our animal-free dairy protein is completely vegan as well as lactose-, hormone-, and antibiotic-free. However, because it’s identical to the proteins from cows, it does contain milk allergens, which are labelled on products made with Perfect Day, “Contains: Milk Protein.”

  • Does Perfect Day protein contain lactose?

    No! Our dairy protein is 100% lactose-free.

  • Does Perfect Day protein contain hormones or antibiotics?

    No! Our dairy protein is naturally hormone- and antibiotic-free.

  • Is Perfect Day protein Kosher?

    Perfect Day’s non-animal whey protein is Kosher Certified. Like all food ingredients, our protein could end up in co-branded products that contain other components which are not kosher. Please refer to product packaging to determine whether an individual product is kosher.

  • Is Perfect Day protein gluten-free?

    Yes! Our dairy protein is gluten-free and does not contain wheat, rye or barley. Please note, however, that some products which incorporate our protein may also contain gluten.

  • Is your protein safe?

    Yes. Safety is of paramount interest to us and we have been working closely with regulatory agencies in multiple countries since our company was founded in 2014. Our animal-free protein has been confirmed as Generally Recognized as Safe (GRAS), and has received a “no-objections” letter from the United States Food & Drug Administration (FDA).

  • I have a milk protein allergy. Will I be able to consume products containing your protein?

    Since we make real dairy protein (casein and whey), we encourage you to take the same precautions with products containing our protein as you would with any other food containing dairy, and to rely on the expertise of a health professional.

    Our policy is to include an allergen disclaimer on products containing Perfect Day animal-free dairy protein, e.g. “Contains: Milk protein.”

  • Does your protein contain GMOs?

    No, animal-free protein does not contain GMOs.
    The microflora we work with are really good at producing different kinds of protein naturally. We simply give them instructions for producing exactly the type of protein we want—in this case, the milk proteins casein and whey. We then filter out the flora, leaving only pure protein. In other words, genetic engineering is part of our process, but genetically modified organisms or any detectable genetic material is not present in our protein.

  • Is Perfect Day launching animal-free milk?

    Fluid milk is one of the many products we’re developing with partners. If you know of, work for, own, or are thinking about starting a brand that might want to incorporate flora-made dairy protein, drop us a line!

  • Where can I purchase products made with Perfect Day protein?

    We launched the first animal-free ice cream made with Perfect Day in 2019 and will be launching products with more partners every year! Check out the TASTE page on our website to find out what, where, and how to get your hands on the first products made with Perfect Day. We are continuing to forge new partnerships with food makers around the world that will enable us to bring a whole variety of new animal-free products to market.

  • How will I know a product contains flora-made dairy protein?

    Products made with Perfect Day are required to list our animal-free protein on their ingredient labels as “non-animal whey protein.” This is intended to make clear to people that the protein is nutritionally identical to the protein found in cow’s milk, but is made from a process not involving animals.

    Products containing animal-free dairy protein are required to include an allergen disclaimer as well. For more information, see our FAQ about milk allergies.

  • Do you use animal testing to make your products?

    Obviously, Perfect Day does not support or condone the use of animal testing. Since the beginning, we’ve been motivated by a desire to bring a more compassionate approach to food manufacturing.

    But what we are pioneering – making dairy protein (casein, whey) without animals – has never been done before. It’s an entirely new category of food ingredients, not because of what it is but because of how it is made.

    In order to establish that a new ingredient is safe for human consumption, governmental regulatory agencies require extensive food safety tests. For new ingredients, like ours, these tests often require animal testing to ensure safety for human consumption. While we do not condone the exploitation of animals for either consumption or product testing, this step is, unfortunately, an important part of a) securing partnerships with food companies that will use our protein in their products and help us have widespread impact, and b) assuring consumers that products containing our new ingredients are safe to consume.

    We fully support replacing animal testing with other validated methods to ensure the safety of new food ingredients and always ensure that these animal testing studies are conducted by accredited third-party facilities that follow proper animal welfare guidelines.

  • What does the name Perfect Day mean?

    The name Perfect Day was inspired by a Lou Reed song. Two dairy scientists discovered that calm, happy cows produce the most milk. And cows are happier when they listen to music! One of the songs that made cows produce the most milk was the song ‘Perfect Day’ by Lou Reed. (Who knew cows were so cool?) As a company on a mission to make cows, people, and the planet happier, it seemed like a perfect fit.
