Joyn Foods has secured K-12 approval in South Carolina, allowing school districts to purchase its 50Cut blended meat—combining beef with mushrooms and mycelium—through a statewide procurement scheme.
The product uses solid-state fermentation to grow mycelium in just eight days, requires 95% less land and 99% less water than conventional beef, and adds fibre, potassium, iron, and vitamin D to an otherwise nutritionally limited protein source.
Student acceptance rates reached 96% for meatballs and 92% for burgers, a result that positions blended mycelium meat as a credible candidate for broader adoption across the United States' National School Lunch Program.
A Fungal Foot in the School Door
Joyn Foods, formerly known as Mush Foods, has achieved what many food-tech companies only dream of: approval to sell its mycelium-enhanced blended meat directly into America's school system. The South Carolina Purchasing Alliance (SCPA) has cleared the startup's 50Cut product line for statewide K-12 procurement, a milestone that is considerably harder to reach than it sounds.
Gaining K-12 approval demands full compliance with USDA meal pattern requirements, competitive pricing validation, detailed product specifications, and—critically—a demonstrated track record of student acceptance. Many products fail at the tasting stage. Joyn Foods passed with unusual ease. In tastings conducted across Berkeley County schools, meatballs achieved a 96% approval rating among students, and burgers 92%. Even the notoriously exacting palates of children in Years 1 and 2 (K-2) returned an 84% positive score. These are not the numbers of a product that merely tolerates scrutiny.
What Is Actually in the Burger?
The mechanism behind 50Cut is more interesting than its name suggests. Joyn Foods cultivates mycelium—the root-like, thread-forming body of fungi—on organic substrates derived from upcycled agricultural side-streams, using solid-state fermentation. In this process, the mycelium grows not in liquid tanks but on solid material, mimicking its natural environment. The entire growth cycle takes roughly eight days, compared to the months or years required for conventional livestock production.
Once harvested, the mycelium is blended with roasted mushrooms to deepen moisture and umami character, before being combined with conventional meat—beef, chicken, or pork—at an inclusion rate of 30 to 50%. The result is a product that behaves identically to standard ground beef during preparation and service, requiring no equipment changes or chef retraining.
The nutritional case is straightforward. Mushrooms and mycelium contribute complete protein, dietary fibre, potassium, iron, calcium, and vitamin D—nutrients conspicuously absent from animal proteins alone. The blend also reduces saturated fat, cholesterol, and sodium relative to an all-beef product. Environmentally, the arithmetic is striking: 50Cut uses over 95% less land and 99% less water than beef production of equivalent weight.
This positions the product neatly within a broader trend. Revo Foods has pioneered 3D-printed mycelium salmon, whilst Mush Foods previously unveiled its 50Cut mushroom blend in an earlier funding round, demonstrating that the mycelium-meat hybrid category has been building commercial momentum for some time. The regulatory trajectory is also gathering pace: the US Better Meat Co. received a no-further-questions letter from the FDA certifying its mycoprotein, and Fable Food launched a shiitake-beef blend in Texas—America's largest cattle-producing state—signalling that blended meat is no longer niche.
Scale and What Comes Next
The commercial opportunity is not trivial. The US National School Lunch Program serves nearly 30 million meals every school day, and schools collectively rank among the largest purchasers of ground beef in the country. A marginal reformulation at this scale translates into millions of meals affected annually, with downstream consequences for land use, water consumption, and children's dietary fibre intake.
Joyn Foods' founder and chief executive, Shalom Daniel, has emphasised that the company's aim is not simply to satisfy sustainability metrics but to meet "real-world performance standards"—meaning taste, operational simplicity, and price. The SCPA approval creates a template for expansion through additional school purchasing co-operatives currently exploring blended meat solutions.
Beyond schools, 50Cut already features in foodservice through partnerships with Pat LaFrieda (blended burgers), Nuchas (empanadas), and Dufour Gourmet (sausages). The K-12 approval, however, carries a symbolic weight that foodservice distribution does not: it places mycelium inside the daily nutritional infrastructure of American childhood, one meatball at a time.
