AB Agave americana contains inulin as storage carbohydrate. Therefore, agave is interestingto be used for the extraction of inulin by pressing. The yield of the process is low due tothe high hardness of the core. The objective of this work was to evaluate pretreatments toreduce the hardness in the process of obtaining inulin by pressing. Treatments with water,sulphuric acid 1 % (by mass) or sodium hydroxide 1 % (by mass) were tested and optimized. The pretreatment of the core of A. americana with sulphuric acid 1 % allowed thereduction of hardness from 30 000 g to 2000 g of breaking force. The mathematical modelobtained predicts an optimum processing at 84 °C during 75 min. The treatment withsulphuric acid 1 % also allows white core of A. americana to be obtained, while the othertreatments provide yellow core. These results open a good alternative to obtain valueadded products from this resource
