FDA to startup: Your vegan mayonnaise can’t be called mayonnaise

A San Francisco food-tech startup has received a warning letter from the Food and Drug Administration (FDA), saying that the company’s eggless mayonnaise cannot be called "Just Mayo."

Hampton Creek Foods, which was founded in 2011, aims to use various plants instead of animal products as substitutes in common foods—such as replacing eggs in pre-packaged cookie dough or mayonnaise.

The company’s products, including "Just Mayo," are commonly sold at Whole Foods, Safeway, and other major supermarkets.
