The liquid form of inulin can replace sugars and sugar alcohols to develop reduced-sugar, low-calorie and fiber-enriched food products, and masks the aftertaste of high-density sweeteners. Products containing this ingredient can make claims like "good/excellent source of fiber", "fiber-enriched", "sugar-reduced", "prebiotic" and "low-calorie".

Ingredients that cause this fermentation process and increase the level of good bacteria in the colon are called “prebiotics”. Liquid inulin also makes an excellent fat and sugar replacement in calorie-reduced foods.
