HSWT produces food-grade aspartame for well-known brands of soft drinks, juices, chewing gums and tabletop sweeteners. In addition, HSWT produces pharma-grade aspartame that is used by well-known pharmaceutical companies in their product formulations. While in the past the plant has produced other sweeteners, HSWT today has a pure focus on the manufacturing high-quality aspartame for the food and pharmaceutical industries. Aspartame is produced from combining amino acids which are commonly present in natural food proteins. Aspartame is digested by the human body in the same way that proteins are and the sweetener is approved by more than 120 countries, including the EU and USA.
