The article "Research and Technologies to Reduce Grain Postharvest Losses: A Review" by Bidhan Nath, Guangnan Chen, Cherie M. O’Sullivan, and Dariush Zare provides a comprehensive review of postharvest losses (PHL) in cereal grains and the technologies available to mitigate these losses. The authors highlight that PHL is a significant issue, affecting food availability and security, and that it occurs across various stages of the supply chain, from farm to market. The review covers the extent of PHL, its causes, and the impact of different crops and regions. Key factors contributing to PHL include genetic variation, climatic conditions, maturity of grain, and postharvest operations. The article also discusses the use of advanced technologies such as mechanized harvesting, improved drying methods, and modern storage systems to reduce PHL. Additionally, it explores the role of non-technological factors, such as infrastructure and market conditions, in reducing PHL. The authors emphasize the need for interdisciplinary research and funding to develop and implement effective PHL reduction strategies, particularly in developing countries. The article concludes with a discussion on the societal and economic benefits of reducing PHL, including improved food security and increased profitability for farmers.The article "Research and Technologies to Reduce Grain Postharvest Losses: A Review" by Bidhan Nath, Guangnan Chen, Cherie M.
