This study investigates a novel preparation technique for pellets made from acetylated inulin and their characterization focusing on specific intestinal delivery of 5-aminosalicylic acid. By means of acetylation the hydrophobicity of four native inulins was increased yielding materials with selected degrees of acetylation. The acetylated inulins were insoluble in water, which was confirmed by the log P-values ranging from 1.30 to 1.58. 5-Aminosalicylic acid loading capacity of the pellets was up to 60 % and high enough to match the ther
