Abtsract: Recent studies have shown that orange residues are an excellent organic material due to their composition, these can be used to obtain high value-added products, and can also be used for energy generation, bio-methanization and composting, among others. This study revealed that orange residues contain high amounts of carbohydrates, so they are prone to almost immediate decomposition after processing the fruit. The main objective of this project was avoid immediate decomposition of orange residues through developing a biotechnological process for the stabilization and conservation of orange residues. The process or technology selected was silage, where lactic acid bacteria (BAL) are used, which they produce lactic acid as the main metabolic product from carbohydrates through the lactic fermentation process, automatically inducing the preservation of organic material due to the low level of pH present within the silos. Once the silage conditions were defined, significant results were achieved; it was observed that silage helps to extend the shelf life of the orange residues up to 10 days keeping them fresh as if these residues had just left the process.
