Marina Koren at Government Executive writes that the Food & Drug Administration recently “sent a warning letter to the makers of Just Mayo, a vegan mayonnaise spread.”
The FDA is concerned that the company may be deceiving buyers who believe they are buying mayonnaise when, in fact, Just Mayo is nothing of the sort. Why, it contains no eggs!
And
According to the standard of identity for mayonnaise, egg is a required ingredient (21 CFR 169.140(c)); however, based on the ingredient information on the labels, these products do not contain eggs. We also note that these products contain additional ingredients that are not permitted by the standard, such as modified food starch, pea protein, and beta-carotene, which may be used to impart color simulating egg yolk. Therefore, these products do not conform to the standard for mayonnaise.
The company that produces Just Mayo, Hampton Creek, now has “15 days to respond to the food safety agency’s memo.”
Fifteen days. Took a little longer than that, didn’t it, for the IRS to produce the Lois Lerner e-mails?
