Description
Leidy Valentina Olaya Bocanegra and colleagues turn rejected potatoes into recovered starch, tuning the extraction with a structured experiment, in a 2026 study. The feedstock was Pastusa variety tubers turned away by a snack processor in Bogotá, Colombia. Temperature, the ratio of solids to liquid, and citric acid strength were varied in a standard response-surface design.
Temperature and the solids ratio drove results most strongly. Rejected tubers yielded notably more starch than sound commercial potatoes run under the same best settings, nearly twice as much. Repeat runs stayed tight and consistent, and a color test with iodine confirmed the product behaved like native, amylose-rich starch. The work frames farm waste as a workable industrial input.
