El proceso de elaboración tradicional del pimiento en la Región de Murcia está regulado oficialmente por la Denominación de Origen "Pimentón de Murcia". Consta de operaciones unitarias de recolección, secado de la cáscara al Sol o con aire caliente, desrabado y desbinzado, trituración grosera, molturación, transmisión, granulado y mezclado, esterilizado, envasado y conservación refrigerada. Se describen detalles de los requerimientos técnicos de las operaciones. Posteriormente se revisan los atributos de calidad y riesgos del producto y del proceso, y mejoras tecnológicas recientemente propuestas para el proceso. Las innovaciones posibles incluyen diseño higiénico de proceso y producto, el uso de flujo de nitrógeno en el transporte y almacenamiento de la cáscara pretriturada, pretratamientos térmicos previos a la molienda, aplicación de altas presiones hidrostáticas o pulsos eléctricos de alta intensidad, irradiación, secado (deshidratación osmótica, liofilización), mezclado y aplicación de recubrimientos, o envasado en atmósfera modificada.

The process consists basically in manual harvesting the fruit in full ripe stage, drying, removing the peduncle and seeds, hammer and stone milling for crushing and grinding, transmission, mixing and granulating, sterilization, packaging and refrigerated storage. The details about the paprika processing operations are reported. In a second part the main control points of paprika processing, paprika quality traits and risks are also mentioned. The innovations proposed for paprika processing and unit operations in the literature include application of hygienic food processing design, paprika processing in a nitrogen flow, heat pretreatments before grinding or applied to shredded pepper, high hydrostatic pressure or high intensity electrical field pulse, irradiation, osmotic dehydration, lyophilization, mixing and coating, and modified atmosphere packaging.
