JOYN Foods wins South Carolina K-12 approval for its mycelium ingredient 50Cut, with Sysco and Compass Group distributing nationwide

31 Mar 2026

A US startup is turning mushroom roots into a cost-cutting protein solution for school cafeterias, and the results are hard to ignore.

JOYN Foods, the company behind a mycelium ingredient called 50Cut, has secured approval from the South Carolina Purchasing Alliance, opening the door for school districts statewide to procure the product through official channels. Student testing in Berkeley County schools backs the launch: 96% approval for meatballs, 92% for burgers. Those numbers matter. School cafeterias are among the most demanding, price-sensitive foodservice environments in the country, and satisfying a student panel is no small thing.

The timing is strategic. US schools collectively represent one of the nation's largest buyers of ground beef, with procurement decisions driven by razor-thin per-meal budgets. JOYN Foods says 50Cut costs 25 to 30 percent less than commodity beef, a figure that carries real weight in institutional purchasing circles.

The ingredient is made through solid-state fermentation using edible mushroom strains grown on upcycled substrates like wood chips and beer waste. It blends with conventional ground meat at ratios ranging from 30/70 to 50/50, acting as a natural binder that absorbs fats, enhances flavor, and adds dietary fiber, while lowering saturated fat and the product's overall carbon footprint. Because it relies on edible mushroom varieties, consumer labeling stays simple and legally clean.

JOYN Foods already distributes through Sysco and Compass Group, supplying universities, hospital systems, hotels, and corporate dining programs nationwide. Monthly revenues now exceed $250,000 and are climbing at 13 to 14% month-over-month. The company projects revenues will triple in 2026, with profitability targeted by early 2027.

South Carolina is the first state approval, but the model is designed to scale. With a capital-light production setup, established distribution partners, and verified student acceptance data, JOYN Foods is building the infrastructure for a national rollout. In a sector still searching for its commercial breakthrough, the school cafeteria may turn out to be alternative protein's most reliable proving ground.
