This book includes the impact, compression, vibration studies, and destructive and nondestructive techniques for bruise measurement. It is essential to detect bruises in the early stages of their formation and conduct a quantitative analysis of the degree of bruising, to ensure the accurate grading of bruised fruits and vegetables and reduce unnecessary economic losses. Bruise damage occurring between the point of harvest and consumption contributes the most to the decrease in fruit quality, reducing the market value and ultimately leading to significant reductions in potential revenue. SDG 12.3 aims to “by 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses.” This book presents recent technological developments in bruise measurement, detection, and analysis of fresh horticultural produce. Given the rising demand for rapid and accurate methods of quality measurement in the horticultural produce industry, this book covers destructive and nondestructive techniques for bruise measurement. Selected applications of different nondestructive methods for various fresh produce commodities are also included. This book will interest graduate and undergraduate students, researchers, academics and engineers working in different aspects of the mechanical damage affected by postharvest handling practices, professionals working in the governments, and other authorities related to fresh horticultural produce quality, regulations, and safety.
