17 Nov 2021 --- Food-tech start-up Aqua Cultured Foods has signed a Proof of Concept (PoC) with Migros, Switzerland’s largest retailer, to advance the development of its seafood alternatives with a realistic taste and texture. Aqua uses microbial fermentation to “grow” its protein, and is developing the world’s first whole-muscle cut, sushi-quality filets of tuna and whitefish, as well as shrimp and calamari alternatives, based on its novel fermentation technology.
