Hampton Creek may have won the battle - to get around the 1938 Code of Federal Regulations, which govern ‘standards of identity’ and was created specifically to prevent companies from selling fake food using established names - but lost the war.

If they can sell mayonnaise outside the definition of mayonnaise, so can food giant Unilever. And that is just what is happening. "Just Mayo", meet the egg-free alternative to Hellmann's. 

The new name: “Hellmann’s Carefully Crafted Dressing&Sandwich Spread.”

Hampton Creek may not be sweating it. Their revenues in 2015 were up 350%. Or maybe they will be part of Unilever soon.
