Since chitosan complies with the definition of dietary fibre is necessary to study the interaction of this biopolymer with nutrients. Yogurt with fortified chitosan and different types of plants fibres like wheat, bamboo, apple, psyllium and inulin was used as a food model. The availabilities of glucose and calcium in this model were studied by an in vitro gastrointestinal tract simulation. Results showed that the different fibres decreased both glucose and calcium availabilities whereas the effect of chitosan was more pronounced. (17.7 ± 2.1% and 21.0 ± 2.5% depress, respectively). This work demonstrated that the addition of chitosan to yogurts influences the availability of nutrients.
