Senomyx, in seeking permission to market its sweet taste enhancers, said it anticipated them being used at levels from one part per billion in baked goods, to two parts in soups and sauces, to five parts in snacks. Importantly, from a marketing standpoint, the FDA would also allow the food manufacturers to use these taste enhancers in their products without letting us know. They can be lumped together with other chemicals as “natural and artificial flavors” on the ingredient listing.
