Method for the production of dietary fibers intended for the food industry

A method for the production of dietary fibers intended for the food industry, comprising the execution of a first agronomic step related to an entire cultivation cycle of legumes, a second analytical step and a third step of mechanical processing of the legumes, wherein

• said first agronomic step comprises
• at least one sub-step of soil analysis and selection,
• a sub-step of selection, among the varieties of non-genetically modified legume seeds, of the most suitable one for the characteristics of the selected soils and for the cultivation period,
• at least one sub-step of checking for the presence of biotic adversities and/or infestations and suppression thereof by way of selected pesticides,
• a sub-step of harvesting dependent on spot detection of the presence on cultivated legumes of pesticide residues of less than 0.01 mg/kg;
• said second analytical step comprises at least one sub-step of detection and quantification of at least one substance selected from pesticides, mycotoxins, heavy metals;
• said third step of mechanical processing of the legumes comprises at least one sub-step chosen from decortication of the legumes, fiber separation, fiber milling, fiber chilling to cryogenic temperatures.
