This manual provides a standard method for assessing the external and internal quality of mangoes, intended for use by both commercial and scientific personnel. It serves as an assessment and diagnostic tool to enhance communication about mango quality across the supply chain, from farm to retail shelf, by providing a common language to describe quality characteristics, defects, and disorders. Defects are categorised as common or less common, with descriptions, possible causes, and photographs illustrating severity levels. The manual also provides guidance on tolerable severity for different quality grades, reflecting the needs of packhouses, agents, retailers, and consumers.
Originally developed in 2009 by Rowland Holmes, Peter Hofman, and Leigh Barker, this second edition has been updated by Andrew Macnish and Hung Duong (QDPI) to include new information and photographs of both existing and emerging quality defects. Drawing on years of research, development, and monitoring of commercial supply chains, the guide provides a consistent and practical framework for evaluating mango quality throughout the supply chain.
