ABSTRACT

The objective of this work is to study the modifications of the physical and structural treatments on the properties of taro starch (Xanthosoma sagittifolium) a species cultivated in Côte d'Ivoire and used in human nutrition compared to a standard corn starch. The influence of treatments in a context where sustainable development appears to be a major priority is part of a broad theme of valorization of agro-resources and the development of transformation processes devoted to renewable carbon resources. The characterization of the modifications of the physical properties of starch, generated by the treatments, was carried out with the aim of linking the differences of the native starches with the behavior of certain starches already used in the pharmaceutical field as excipients (analysis of images, hardness, densification, specific surface area and porosity). The physical treatments applied to the starches led to more or less significant modifications of their structures. The results of this study are even favorable to the use of this starch as a diluent in pharmaceutical forms.
