Decentralized Food Processing Technologies in Rural India: A Review of Technical Advancements and Socioeconomic Impacts

Abstract

The Indian food processing sector, a vital sunrise industry with a CAGR of 9.97%, faces a critical challenge where over 90% of agricultural production originates in rural areas yet suffers from annual post-harvest losses of approximately ₹90,000 crore due to a lack of village-level infrastructure. While centralized processing exists, a significant gap remains in the availability of affordable, decentralized, and energy-efficient technologies that allow primary producers to bypass intermediaries. This study addresses these systemic bottlenecks by evaluating the performance and socioeconomic impact of emerging innovations such as mini dal mills, solar tunnel dryers, and compact oil expellers. The review reveals that these technologies significantly enhance efficiency, such as achieving 80–84% pulse de-husking yields and extending the shelf life of perishables beyond one year. These technological interventions catalyse rural entrepreneurship and women’s empowerment through Self-Help Groups (SHGs) and Farmer Producer Organizations (FPOs). The integration of low-cost Industry and standardized quality-assurance frameworks is proposed as the essential path for transitioning rural producers into competitive participants in the global value chain.
