The effects of time and temperature on the postharvest quality of fruits and vegetables are visually depicted in the Color Atlas of Postharvest Quality of Fruits and Vegetables. Through hundreds of vibrant color photographs, this unique resource illustrates how the appearance (e.g., color, shape, defects and injuries) of fruits and vegetables changes throughout their postharvest life and how storage temperature greatly contributes to critical quality changes. The book’s extensive coverage describes 37 different fruits and vegetables from different groups that were stored at five specific temperatures and photographed daily after specified elapsed periods of time. Individual fruits and vegetables from the following groups are covered: subtropical and tropical fruits pome and stone fruits soft fruits and berries cucurbitaceae solanaceous and other fruit vegetables legumes and brassicas stem, leaf and other vegetable and alliums Information is provided about each individual fruit/vegetable such as characteristics, quality criteria and composition; recommendations for storage, transport and retail; and effects of temperature on the visual and compositional quality of each individual fruit or vegetable, associated with photos of the appearance at particular times and temperatures. This visual documentation shows how important is to handle fruits and vegetables at the right temperature and what happens if the recommendations are not followed. Also shown is the importance of the initial harvest quality of the fruit/vegetable and the expected shelf life as a function of quality at harvest, storage temperature and storage time. The Color Atlas of Postharvest Quality of Fruits and Vegetables will appeal to a diverse group of food industry professionals in the areas of processing, distribution, retail, quality control, packaging, temperature control (refrigerated facilities or equipment) and marketing as a reference tool and to establish marketing priority criteria. Academic and scientific professionals in the area of postharvest physiology and technology, food science and nutrition can also use the book as a reference either for their study or in class to help students to visualize changes in the appearance of fruit/vegetables as a function of time/temperature.
Focusing exclusively on postharvest vegetable studies, this book covers advances in biochemistry, plant physiology, and molecular physiology to maximize vegetable quality. The book reviews the principles of harvest and storage; factors affecting postharvest physiology, calcium nutrition and irrigation control; product quality changes during handling and storage; technologies to improve quality; spoilage factors and biocontrol methods; and storage characteristics of produce by category. It covers changes in sensory quality such as color, texture, and flavor after harvest and how biotechnology is being used to improve postharvest quality.
This book, chock full of color illustrations, addresses the main postharvest physiological disorders studied in fruits and vegetables. For a wide variety of fruits and vegetables, Postharvest Physiological Disorders in Fruits and Vegetables describes visual symptoms, triggering and inhibiting mechanisms, and approaches to predict and control these disorders after harvest. Color photographs illustrate the disorders, important factors, physiology, and management. The book includes a detailed description of the visual symptoms, triggering and inhibiting mechanisms, and possible approaches to predict and control physiological disorders. The mechanisms triggering and inhibiting the disorders are discussed in detail in each chapter, based on recent studies, which can help readers better understand the factors regulating each disorder. The description of possible approaches to predict and control each disorder can help growers, shippers, wholesalers, and retailers to determine the best management practices to reduce disorder incidence and crop losses. Features: Presents visual symptoms of postharvest physiological disorders that will help readers to precisely identify the disorders in fruits and vegetables Details mechanisms triggering and inhibiting the postharvest disorders Explains possible approaches to predict and control these disorders Suggests the best postharvest management approaches for each crop Although there are many scientific publications on postharvest physiological disorders, there are no recent reviews or books putting together the most recent information about the mechanisms regulating, as well as about the possible approaches to predict and control these disorders.

Focusing on the great variety of research being done in the field of postharvest pathology, this volume presents a collection of topics concerning the diseases of harvested fruits and vegetables.Each chapter represents a separate unit which taken together create a better understanding of the whole subject. Topics include the causal agents of postharvest diseases of fruits and vegetables, their sources and their ways of penetration into the host; factors that may accelerate the development of the pathogen in the host - and those that suppress them; a list of the main pathogens of fruits and vegetables, their hosts and the diseases elicited by them; and a detailed description of the major diseases of selected groups of fruits and solanaceous vegetable fruits. Attack mechanisms of pathogens and defense mechanisms of the host are examined as are treatments aimed at suppressing postharvest diseases. The search for natural and safe chemical compounds and the variety of alternative physical and biological methods for use in postharvest disease control are emphasized.Teachers and students who focus on postharvest pathology, scientists in research institutes, companies dealing with fruit and vegetable preservation technologies and for all those striving to improve the quality of harvested fruits and vegetables will find this book of great interest.
In contrast to the second edition, the third edition of ‘‘Fungi and Food Spoilage’’ is evolutionary rather than revolutionary. The second edition was intended to cover almost all of the species likely to be encountered in mainstream food supplies, and only a few additional species have been included in this new edition. The third edition represents primarily an updating – of taxonomy, physiology, mycotoxin production and ecology. Changes in taxonomy reflect the impact that molecular methods have had on our understanding of classification but, it must be said, have not radically altered the overall picture. The improvements in the understanding of the physiology of food spoilage fungi have been relatively small, reflecting perhaps the lack of emphasis on physiology in modern mic- biological science. Much remains to be understood about the specificity of particular fungi for particular substrates, of the influence of water activity on the growth of many of the species treated, and even on such basic parameters as cardinal temperatures for growth and the influence of pH and preservatives. Since 1997, a great deal has been learnt about the specificity of mycotoxin production and in which commodities and products-specific mycotoxins are likely to occur. Changes in our understanding of the ecology of the included species are also in most cases evolutionary. A great number of papers have been published on the ecology of foodborne fungi in the past few years, but with few exceptions the basic ecology of the included species remains.
Completely revised, updated and enlarged, now encompassing two volumes, this third edition of Fruit and Vegetables reviews and evaluates, in comprehensive detail, postharvest aspects of a very wide international range of fresh fruit and vegetables as it applies to their physiology, quality, technology, harvest maturity determination, harvesting methods, packaging, postharvest treatments, controlled atmosphere storage, ripening and transportation. The new edition of this definitive work, which contains many full colour photographs, and details of species not covered in the previous editions, provides key practical and commercially-oriented information of great use in helping to ensure that fresh fruit and vegetables reach the retailer in optimum condition, with the minimum of deterioration and spoilage. With the constantly increasing experimental work throughout the world the book incorporates salient advances in the context of current work, as well as that dating back over a century, to give options to the reader to choose what is most relevant to their situation and needs. This is important because recommendations in the literature are often conflicting; part of the evaluation of the published results and reviews is to guide the reader to make suitable choices through discussion of the reasons for diverse recommendations. Also included is much more on the nutritional values of fruit and vegetables, and how these may vary and change postharvest. There is also additional information on the origin, domestication and taxonomy of fruit and vegetables, putting recommendations in context. Fruits and Vegetables 3e is essential reading for fruit and vegetable technologists, food scientists and food technologists, agricultural scientists, commercial growers, shippers, packhouse operatives and personnel within packaging companies. Researchers and upper level students in food science, food technology, plant and agricultural sciences will find a great deal of use within this popular book. All libraries in research establishments and universities where these subjects are studied and taught should have copies readily available for users.
Among the Horticultural Crops, Fruits and Vegetables (FV) are of primary - portance as the key source of essential components in an adequate and balanced human diet. FV have supported largely the daily food requirement of mankind since ages and even before man learned to grow cereal crops systematically. Over the years, growing FV has been the mainstay of rural economy and has emerged as an indispensable part of agriculture world over, offering farmers a wide range of crops in varied topography and climate. In certain parts of the world, FV are the major dietary staple. Apart from being a rich source of vitamins and minerals, this sector also contributes significantly in economy of the region or the nation. The increased income from per unit area of FV is far ahead and can not be compared with that of cereal crops. A recent survey by the Economist revealed that the world population has - creased by 90 % in the past 40 years while food production has increased only by 25 % per head. With an additional 1. 5 billion mouth to feed by 2020, farmers worldwide have to produce 39 % more. Looking at the load of the future food requirement, the global increased production of FV during last few years has absorbed the additional food requirement and accordingly the eating habits are also changing and shifting - wards more consumption of these commodities worldwide.
