Larch arabinogalactan (AG) is one such tool for food formulators. AG is a naturally occurring, water-soluble polymer found in high concentrations in the Larix genus of trees. Not only does AG function as a prebiotic fiber and immune enhancer, it also retains moisture, enhances mouthfeel and bulk, and improves shelf stability.
Because of AG's low-viscosity profile and emulsification enhancing properties, the most ready applications include refrigerated and non-refrigerated beverages, and beverage mixes. Interest has also been expressed for snack foods, bars, ready-to-eat cereals, yogurt/dairy products and baked goods, says Lori Siegler, product manager, Larex Inc., St. Paul, Minn.
