Modern and conventional processing technologies and their impact on the quality of different millets

Millet, the highly sustainable crop for farming and combating hunger, has recently regained a resurgence in popularity as people seek more sustainable and nutrient-dense alternatives. International organizations and research institutions have advocated for increased millet production and consumption by introducing novel technologies and machinery in response to global food security and climate change challenges. This review aims to identify the impact of modern and conventional processing technologies on the quality of different millets. A comprehensive analysis of research reviews reveals that double-stage and tabletop centrifugal dehullers, infrared roasting, pulsed light, ultrasound, high-pressure processing methods, fortification, and encapsulation are optimal for nutrient retention in various millets. Extrusion technology application in millet processing has created a diverse range of value-added products with extended shelf stability. Emphasis is needed to develop robust promotion and distribution channels and establish an export promotion forum involving all stakeholders to promote and diversify millet-based products and technologies.
