Critics worry the high cost of cultivated meat, alongside regulatory hurdles and unproven scalability, make it mostly hype for now. Read more at straitstimes.com.
NEW YORK – Cultured meat. Cultivated meat. Lab-grown meat. Cell-based meat. Whatever you call it, the newest addition to alternative protein is having a bit of a moment.
Take fish maw, for example. The swim bladder of a fish, it’s considered a delicacy in many Asian countries. To create a lab-grown version of croaker fish maws, scientists from Hong Kong-based Avant Meats place fish cells in a culture medium containing dozens of different nutrients, and store them in a bioreactor connected to an oxygen tank. Within weeks, those cells proliferate into tissues the size of a grain of rice, at which point they’re ready for assembly into larger pieces.
Different proteins present different complications, though: Makers of cell-based seafood don’t have the advantage medical research gives those cultivating mammalian cells, for example. And meats made up of more complex tissue and texture can be more difficult to construct – a process known as “scaffolding” that holds together muscle, fat and connective tissue to recreate meat’s structure.
Experts say that’s unlikely to change any time soon. Scaling up the production of cultivated protein from a pilot stage to a commercial level requires technological advances, industry observers say, and massive bioreactors required for mass manufacturing don’t exist yet. But when it comes to the climate impact of cultivated protein, the answer isn’t entirely straightforward. Growing meat from cells in bioreactors does use far less land than traditional farming, and avoids a lot of the emissions associated with, for example, cow burps. It could also allow companies to produce meat closer to their consumers, reducing the amount of fuel needed to deliver foodstuffs.
Most doubts about cultivated protein have to do with its limitations: For now, it’s still highly expensive to produce, which makes widespread sales – even with regulatory approval – difficult to imagine any time soon.
