Inulin and oligofructose are mixtures of β (2→1) linked fructans; in most chains the terminal sugar is glucose. The degree of polymerization ranges between 3 and 60 and between 2 and 7 for inulin and oligofructose, respectively (1). Because of their structure, these compounds are not digested by the alimentary enzymes of man, so that they are considered fiber in most countries. Among their nutritional attributes, these substances stimulate beneficial gut microflora (1) and relieve constipation (2), as well as improving calcium availability (3). A potential reduction of cancer risk has also been advanced (4). Their calorie value is estimated to be 1.5 kcal/g (5). Functional properties such as solubility, water retention capacity and taste allow their use as macronutrient substitutes and or as soluble fiber supplements
