The ingredients in Sensa are safe to ingest, according to Healthline and Toxnet. Sensa's ingredients are maltodextrin, tricalcium phosphate, silica and various flavors, in flakes that consumers sprinkle on food like seasoning, according to WebMD.
Approved by the U.S. Food and Drug Administration as a safe food additive, maltodextrin is an ingredient in many foods such as canned fruits, sauces, salad dressings and sports drinks, notes Healthline. It is a simple carbohydrate with a slightly sweet taste. Food manufacturers use silicon dioxide, or silica, as an additive to stop ingredients from clumping together. Silicon dioxide naturally occurs in plants, such as beets, bell peppers and oats, and the FDA and the World Health Organization have approved it as safe to consume.
Tricalcium phosphate is an odorless, tasteless white crystalline substance that food manufacturers use to clarify syrups and to prevent caking, notes Toxnet. It is non-irritating and nontoxic in normal quantities.
