Perfect Day Foods have discovered a revolutionary way to replicate cow DNA through 3D printing, allowing them to create a tasty dairy alternative that is vegan, and both lactose- and gluten-free.

Company replicates cow DNA through 3D printing to create realistic vegan dairy alternatives

3D printing has a whole host of uses, but one that you might not previously have thought of is the use of additive manufacturing to create cow’s milk — minus the cows.

That’s the mission statement of a startup called Perfect Day Foods, founded by two twenty-something biomedical scientists. Perfect Day’s plan? To create a lactose-free milk substitute that’s a whole lot closer to the real thing than existing milk substitutes.

Since they were founded back in 2014, Perfect Day Foods have worked to raise a total of $4 million in investment funds for the 3D printing of this bovine DNA and subsequent new type of ‘dairy’ which can be used to make creams, milks, cheeses, ice-creams and more!

“Just before we started this company, my co-founder Perumal Gandhi and I had recently adopted a plant-based diet and were finding it hard to live without some of our favourite foods: namely, ooey, gooey, cheesy pizza” – co-founder and CEO Ryan Pandya 

He continued that the pair knew of people who were using food technology to create meat without animals, and wondered why nobody was doing the same for milk.

“Our goal isn’t to be an alternative, it’s to be delicious,” he continued. “So whether it’s a Perfect Day yogurt, cheese, butter, or ice cream, it will taste as good as the real thing and be better for you. We want to empower people to enjoy the foods they love, while making the world a greener, kinder place. We don’t think you should have to sacrifice one of the other.”

As Pandya explained, Perfect Day uses yeast fermentation to make its milk, utilising 3D-printed cow’s DNA as part of the process.

“It’s a process akin to craft brewing and … allows us to create real milk proteins that are identical to the ones found in cow’s milk, without a single cow,” he said. “First, we start with a yeast that’s safe and well understood, which we sourced from the USDA. We give this standard yeast a ‘blueprint’ from 3-D printed cow DNA that allows it to ferment sugar and create real milk proteins. We then carefully separate these milk proteins and combine them with plant-based sugar, plant-based fats, and nutrients to produce a product that has the identical taste and texture of cow’s milk, but packs in more nutrition with no food safety or contamination concerns.”


Perfect Day’s animal-free dairy milk sounds like the perfect product for those who are transitioning to a vegan lifestyle, but who are finding things like cheese difficult to cut out. In fact, it’s so close to the real thing — including the taste, texture, and nutrition — that if you have milk allergies, you’ll need to opt out on this product. (They are currently “working on hypoallergenic innovations,” however.).

As to when customers will be able to get their hands on Perfect Day’s vegan, lactose-free, more sustainable milk substitute, Pandya told Digital Trends it won’t be too long. “We’re focused on product formulation and commercialisation as we look to bring our products to market (in the USA) by the end of next year,” he said.
