The self-sustaining nature of renewable energies makes it necessary to continuously search for substrates that satisfy a growing interest in the production of biofuels, taking care of areas such as food security. In this work we optimized a hydrolysis process of Opuntia ficus-indica cladodes using acid diluted and surface response methodology. The nopal is a secondary crop widely distributed in arid and semi-arid zones and recently investigated for its potential in the biofuel industry given its versatility as a crop. The result of this optimization was the production of 20,825 mg mL- 1 of total reducing sugars (TRS), at 27.25 minutes of reaction and with a solution of 3.46% sulfuric acid. The main sugars obtained in the hydrolyzed were galactose (57.14%), arabinose (20.51%), glucose (13.18%) and xylose (9.17%). Also, it emphasizes the value of humidity of this culture (90%) and the low amount of lignin present (2.70%).
