To make its animal-free egg alternative, Every engineered the yeast Komagataella phaffii (formerly named Pichia pastoris) to express egg proteins. The yeast grows in bioreactor tanks and secretes protein into the broth, which is then filtered. Because the genetically engineered yeast is no longer present in the final product, Every Egg is not considered bioengineered. It has received Generally Recognized as Safe designation from the US Food and Drug Administration. Every will be working closely with Palacios’ R&D team to integrate its whole alternative egg into Spanish omelet products and comply with European Union regulatory requirements.

The recently signed partnership between Every and the La Rioja, Spain-based multinational food group not only offers an animal-free alternative to a beloved traditional dish, but also highlights how precision fermentation can help strengthen food supply chains. Lance Lively, vice president and general manager at Every, says their products are a cost-competitive and reliable solution to the “troubled egg supply chain,” pointing out that outbreaks of avian influenza have decimated flocks, affecting egg supplies and causing prices to reach record highs. Other egg protein alternatives, like Bioalbumen, produced by the Finnish biotech Onego Bio, come in powder form, whereas Every Egg is a liquid.

为了制作不含动物成分的鸡蛋替代品，Every 设计了酵母Komagataella phaffii （以前称为毕赤酵母）来表达鸡蛋蛋白。酵母在生物反应器罐中生长，并将蛋白质分泌到肉汤中，然后过滤。由于最终产品中不再存在基因工程酵母，因此“每个鸡蛋”不被视为生物工程产品。它已获得美国食品和药物管理局的公认安全称号。 Every 将与 Palacios 的研发团队密切合作，将其全替代鸡蛋整合到西班牙煎蛋卷产品中，并遵守欧盟监管要求。

Every 与总部位于西班牙拉里奥哈的跨国食品集团最近签署的合作伙伴关系不仅为深受喜爱的传统菜肴提供了无动物成分的替代品，而且还强调了精准发酵如何帮助加强食品供应链。 Every 副总裁兼总经理兰斯·莱弗利 (Lance Lively) 表示，他们的产品是解决“陷入困境的鸡蛋供应链”的具有成本竞争力且可靠的解决方案，并指出禽流感的爆发已导致鸡群大量死亡，影响了鸡蛋供应，导致价格创历史新高。其他鸡蛋蛋白替代品，如芬兰生物技术公司 Onego Bio 生产的 Bioalbumen，是粉末形式，而 Every Egg 是液体。
