Mayonnaise, as defined by the U.S. Food and Drug Administration's Standard of Identity, must contain at least 65% oil by weight, vinegar, and egg or egg yolks. It may contain spices and natural seasonings except turmeric and saffron, as yellow color might suggest added egg yolk. No emulsifying agents other than eggs are allowed, so real mayonnaise does not contain any starches or gums.
