PurposeThe pisco produced in Chile is a distillate from pisco grape varieties, which generates a large amount of grape pomace. However, with the growing interest in reducing the environmental impact and converting these residues into novel by-products, the research and their evaluation in each stage can contribute significantly to ensuring their recovery. This study evaluated the kinetics of vacuum and convective drying from grape pomace at different temperatures and the influence on the retention of polyphenolic compounds and antioxidant activity as scalable alternatives for agro-industry.MethodsThe pisco grape pomace was dried by two drying methods at different temperatures: Vacuum drying (50-100 degrees C
