1. Food Acidulant And Flavour Enhancer: Approved as food additive E363 , it gives a taste profile distinct from citric and malic acid, with lower sourness intensity and a more prolonged savoury finish, which suits soy sauce, bean paste, sake, cheese, meat and beverages.
2. Resins, Coatings, Pigments And Polyester Polyols: One of the largest industrial destinations for the acid, it goes into alkyd and unsaturated polyester resins, surface coatings, dyes and pigments, glass fibre reinforced plastics, ion exchange resins and polyester polyols.
3. pH Buffering And Succinate Salt Formation: Used to form succinate salts and as a buffering component that holds pH steady, which is why it appears as an acidity regulator and buffering agent across food, cosmetic and protein based formulations.
