Eco-Friendly Technology for Postharvest Produce Quality presents the scope of emerging eco-friendly technologies to maintain the postharvest quality of fresh produce in terms of safety and nutrition. The book covers an analysis of the alternative and traditional methodologies pointing out the significant advantage and limitations of each technique. It provides a standard reference work for the fresh produce industry in postharvest management to extend shelf life by ensuring safety first and then nutritional or sensory quality retention. Fruits and vegetables are a huge portion of the food supply chain and are depended on globally for good health and nutrition. The supply of good food, however, greatly depends on good postharvest handling practices. Although substantial research has been carried out to preserve the quality of fresh horticultural produce, further research—especially on safety—is still required. This book provides foundational insights into current practices yielding best results for produce handling. - Includes appropriate approaches, technologies, and control parameters necessary to achieve shelf-life extension without compromising produce quality - Presents successful food safety methods between the time produce is harvested to consumption - Includes the latest information on preservation technologies using novel chemical methods, active packaging, and monitoring the effect of environmental stresses on quality and shelf life of agricultural produce

Mycotoxins are toxins produced by aerobic, microscopic fungus under special conditions of moisture and temperature. They colonize in a variety of foods from harvest to the grocer. Mycotoxins have gained world wide interest in recent years with the revelation of the effect of these toxins on health. A current example is the presence of ochratoxin A, a human carcinogen and nephrotoxin, in wines. The increased concern about fruit safety has led to increased studies throughout the world and enhanced awareness for stringent regulations governing mycotoxin limits in food.Presented in three defined sections, this is the first book to provide comprehensive analysis of the main mycotoxins contaminating fruits and vegetables and their derived products. The first section provides a safety evaluation of mycotoxins in fruits and vegetables, details regarding factors affecting mycotoxin production and diffusion in the fruit tissue, and recent methods for detection of mycotoxigenic fungi and mycotoxins produced by the fungi. The second part takes a critical look at the main individual mycotoxins and the third section focuses on approaches for prevention and control. - The first book dedicated to mycotoxins in fruits and vegetables - Presents mycological, mycotoxicological and phytopathological aspects of fruits and vegetables - Includes an analysis of detection, prevention and control methods for mycotoxigenic fungi and the mycotoxins they produce - Provides a complete risk assessment and safety evaluation of mycotoxins in perishable produce

Fruits and vegetables are an important part of a healthy diet. However, one third of fruit and vegetables are lost after harvest every year. Most losses are caused by pathogen (mostly fungi) infections, which lead to postharvest decay. In addition, some postharvest fungal pathogens can produce toxic secondary metabolites (i.e. mycotoxins) during their infecting periods. Mycotoxin contamination may cause serious food safety issues. At present, the use of synthetic fungicides is still the main means to control postharvest diseases. However, the development of resistance in fungal pathogens to fungicides and the growing public concern over the health and environmental risks associated with high levels of pesticides in fruits and vegetables have urged researchers to develop alternative methods of disease control. A deeper understanding of the infecting mechanisms of postharvest pathogens will provide great insight into developing new controlling strategies.
