Super protein

Prime Roots’ deli meats are made from koji, a type of mycelium similar to mushroom roots. Koji has been used for centuries to make miso and soy sauce, and Prime Roots says koji’s long, microscopic fibers excel at recreating the textures of animal meat. To achieve this, the company has developed a proprietary process that is able to replicate the umami-rich flavor and meaty, dense texture of meat.

The resulting product is non-GMO, and free from soy, cholesterol, nitrates, hormones and antibiotics.

Disrupting deli

Founded by Kimberlie Le and Joshua Nixon, Prime Roots originally began life selling a range of ready-made meals featuring koji-based proteins made to taste like lobster, chicken and beef. In February 2022, the company announced a re-brand and strategic pivot to focus on plant-based deli meats, a segment it said lacked strong leading players. 

Recently, the company joined an all-star list of global fungi companies to form the Fungi Protein Association – a new trade organization to advocate for fungi as a sustainable protein. Prime Roots now states it is on a mission to disrupt the $300Bn bulk deli industry, and its sliceable Koji-Meats are on track to revolutionizing traditonal deli counters.

“Through the power of koji mycelium, we are able to create better-tasting meats for every type of eater,” says Prime Roots’ CEO Kimberlie Le.  “We celebrate the culture of meat at Prime Roots, and our whole, hand-sliced Koji-Meats enable customers to make easy and convenient better-for-you and better-for-the-planet swaps. Our goal is to challenge what makes a meat ‘alternative’ and offer Koji-Meats as an option alongside animal meats in deli counters, sandwich shops, and restaurants nationwide.”
