As the name implies, Beano is an expensive product that is allegedly beneficial in facilitating the digestion of various foods particularly the legumes type. The ingredients you list are: water is a solvent and carrier for this product, sorbitol is a sweetening agent (a saccharide, a simple sugar) salt is used to flavor the product and enhance the sweetness of sorbitol, disodium citrate is a (different) salt that is likely used as a buffer (to maintain a stable pH), potassium sorbate has a similar function for the sweetness, and those substances are called excipients and are inactive and mostly inocuous, but alpha-galactosidase is the active ingredient, an enzyme which breaks down the galactose sugar in various foods, just like beta-lactase breaks down lactose (milk sugar) in various dairy products. I am glad I was able to use the little chemistry I remember from my younger days. Let me know if YOU find it beneficial. Michel
