Not disclosing the ingredients is illegal large part of the world, and people can die if you don’t do that, so the answer is clearly yes in some sense. This is also true for some cooking techniques, like heat treatment of raw meat. I think your analogy is not the best.
Not disclosing ingredients is more like not disclosing dependencies because I am very confident that you can't go into a shop, buy a random food and then construct recipe from list of ingredients.
