This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tomatoes are widely produced and consumed due to their nutritional content and versatility. However, the tomato is a soft fruit liable to damage and flavour deterioration. Hence, the main challenge for the tomato producing industry is to prevent the high loss incurred during harvest, handling and transportation of the crops. The objective of this study was to investigate the overall nutritional implication of controlled storage of tomatoes using ozone on the ripening process and the basic nutritional components of tomatoes. This investigation was also designed to focus on the effect of different ozone doses on the basic components and properties (carotenoids, ascorbic acid, total antioxidant activity and soluble sugars content) of the quality and dynamic maturity of tomatoes. Green tomatoes (Rio Grande) were treated in glass chambers with ozone enriched air [(air + 2, 7 and 21 mg O3/g tomato) and control (air only)] under humidity and temperature of 90-95% and 14-17 oC respectively. Tomatoes were sampled after 14 days of ozone treatment in the storage chamber and analyzed for different quality parameters (appearance, weight loss, Total Soluble Solids (TSS), titratable acidity, total ascorbic acid and carotene) of the ripening. The variety Elegance tomatoes were selected and the fruits were graded by colour and subjected to treatment with ozone (in doses 0 (clean air), 0.25, 0.50, and1.00 mg O3/g tomatoes) during storage for 6 days under the same humidity and temperature conditions. The fruits were analysed for carotenoids, ascorbic acid content, total antioxidant activity and soluble sugars. Analysis of the fruits clearly showed that ozone significantly delayed the development of colour on the surface, particularly in the low doses, and caused black spots on the surface of the tomatoes, particularly in higher ozone doses. Ozone did not affect the ascorbic acid and titratable acidity content. However ozone did reduce the Total Soluble Solids (TSS) by about 10% at the lowest ozone dose. A high inhibition of accumulation of carotenoids, particularly at low dose, of the tomatoes (Rio Grande) was also observed. Tomatoes (Elegance) under ozone treatments contained higher ß-carotene than those under the control treatment and lycopene content increased during storage in the red stage of tomato fruits. Ascorbic acid (AsA), dehydroascorbic acid (DHA) and the total of AsA and DHA concentrations, and ratios of redox (ASA/ (ASA + DHA) and DHA/AsA in pericarp and pulp of tomatoes tissue, did not show clear differences between the different treatments. The concentrations of the glucose and fructose increased in the tomatoes which were subjected to ozone treatments. Results from this study show that controlled atmosphere storage of tomatoes using ozone is a viable technique which warrants further study.

Download or read book Processing and Impact on Active Components in Food written by Victor R Preedy and published by Academic Press. This book was released on 2014-05-27 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: From beef to baked goods, fish to flour, antioxidants are added to preserve the shelf life of foods and ensure consumer acceptability. These production-added components may also contribute to the overall availability of essential nutrients for intake as well as the prevention of the development of unwelcome product characteristics such as off-flavours or colours. However, there are processes that reduce the amount of naturally occurring antioxidants and awareness of that potential is just as important for those in product research and development. There is a practical need to understand not only the physiological importance of antioxidants in terms of consumer health benefit, but how they may be damaged or enhanced through the processing and packaging phases. This book presents information key to understanding how antioxidants change during production of a wide variety of food products, with a focus toward how this understanding may be translated effectively to other foods as well. - Addresses how the composition of food is altered, the analytical techniques used, and the applications to other foods - Presents in-chapter summary points and other translational insights into concepts, techniques, findings and approaches to processing of other foods - Explores advances in analytical and methodological science within each chapter

Available in PDF, EPUB and Kindle. Book excerpt: The food industry is now entering a transition age, as scientific advancements and technological innovations restructure what people eat and how people think about food. Food Tech Transitions provides a critical analysis of food technology and its impact, including the disruption potential of production and consumption logic, nutrition patterns, agronomic practices, and the human, environmental and animal ethics that are associated with technological change. This book is designed to integrate knowledge about food technology within the social sciences and a wider social perspective. Starting with an overview of the technological and ecological changes currently shaping the food industry and society at large, authors tackle recent advancements in food processing, preserving, distributing and meal creation through the lens of wider social issues. Section 1 provides an overview of the changes in the industry and its (often uneven) advancements, as well as related social, ecological and political issues. Section 2 addresses the more subtle sociological questions around production and consumption through case-studies. Section 3 embraces a more agronomic and wider agricultural perspective, questioning the suitability and adaptation of existing plants and resources for novel food technologies. Section 4 investigates nutrition-related issues stemming from altered dietary patterns. Finally, Section 5 addresses ethical questions related to food technology and the sustainability imperative in its tripartite form (social, environmental and economic). The editors have designed the book as an interdisciplinary tool for academics and policymakers working in the food sciences and agronomy, as well as other related disciplines.

This book was released on 2007-05-08 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: We can not talk about commodity production without building up all the operations after harvest. It is possible to market the products just after harvest, but it is only possible in small quantities. Postharvest handling is the ultimate stage in the process of producing quality fresh fruits and vegetables, getting these unique packages of water (fresh commodities) to the supper table. Fresh fruits and vegetables are succeptible to a number of postharvest disease and disorders and the postharvest operations are predominately aimed at maintaining harvest quality. Every step in the handling chain can influence the extent of disease and quality of the stored product. From planting to consumption, there are many opportu- ties for bacteria, viruses, and parasites to contaminate produce or nutrient deficiency level causing physiological disorders. Most of the storage rots are diseases that have originated in the field and have carried over onto commodities after harvest. Physiological disorders also arise from poor handling between harvest, storage and marketing. Treatments have a direct effect on inactivating or outright killing germinating spores, thus minimising rots. Prestorage treatment appears to be a promising method of postharvest control of decay. Pre-or-postharvest treatments of commodities are considered as potentiel alternatives for reducing the incidence of diseases, disorders, desinfestation of quarantine pests and for preserving food quality. Postharvest treatments lead to an alteration of gene expression and fruit ripening can sometimes be either delayed or disrupted.
