Current obstacles

  • Bioreactor scaleFood-grade tanks of tens of thousands of litres are costly and easily contaminated, since no antibiotics are used.
  • State bansFlorida, Alabama and other states ban cultivated meat sales, shrinking the market.

Physics limits

  • Oxygen barely dissolves in water, capping how dense cells can growWarm culture broth holds only about 7 mg of oxygen per litre. Dense cells use it up in seconds, and stirring or bubbling harder damages them, so each tank tops out far below the cell density of real meat.
  • Without blood vessels, thick tissue starves in the middleNutrients and oxygen diffuse only about 0.1–0.2 mm into living tissue. Real meat is fed by capillaries; grown meat thicker than that needs scaffolds or channels, which is why most products are minced or thin.
  • Animal cells grow far slower than germsAnimal cells double about once a day; bacteria can double in 20–30 minutes. A single stray microbe can overrun a batch, so everything must stay sterile like a drug plant, which is costly at food scale.

Grow

Multiply cells in tanks

A small vial of cells is grown in ever-larger bioreactors, doubling about every day or two at set temperature and oxygen.

Differentiate

From cells to tissue

Changes in food and setup push cells to form muscle- and fat-like tissue with a meat texture.

Harvest

Harvest and form

The cell mass is harvested, then shaped and cooked like normal chicken products.

About Upside Foods

The team behind Cultivated chicken

Upside Foods

Cultivated chicken, EPIC plant, FDA/USDA cleared

Berkeley pioneer of cultivated meat, founded as Memphis Meats in 2015. It was first to clear both FDA and USDA review for chicken grown from animal cells (2022-23), but has struggled to scale and paused a big Illinois plant in 2024.

  • First cultivated meat to get FDA 'no questions' (Nov 2022) and a USDA grant of inspection (June 2023).
  • Raised $400M in 2022 at a valuation above $1B, but paused its Rubicon plant in Illinois in 2024.
  • Is fighting cultivated-meat bans in Florida and other states in court.
