Bioactive Compounds in Agricultural Soils


Book Description

This volume looks at the impact that different cropping systems and tillage have on soil’s biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions. The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers. The chapters address fundamental questions relevant to the environmental challenges we face today and will deal with in the future. The results involve asking basic questions motivated by soil's chemical and biochemical processes. The answers will lead to the improvement of the quality of soil’s organic matter, which, in turn, can lead to increased crop yields. Readers will come to understand the relationship between ecological processes and environmental change on individual levels of biocomplexity as well as on systems in their entirety. The title is ideal for students and teachers for laboratory practical classes. Soil scientists, biochemists, chemists, plant ecophysiologists, “Natural Products” organic chemists, and other environmental scientists and specialists will also find it useful.

Phytochemicals in Vegetables: A Valuable Source of Bioactive Compounds


Book Description

Phytochemical compounds are secondary metabolites that plants usually synthesize for their own protection from pests and diseases. Phytochemical biosynthesis is also triggered under specific environmental conditions. They cannot be classified as essential nutrients since they are not required at specific amounts for life sustenance. Phytochemicals in Vegetables: A Valuable Source of Bioactive Compounds presents information about the phytochemical (common and scarce) content of several cultivated vegetables, as well as their health and therapeutic effects based on in vitro, in vivo, animal and clinical studies. Chapters also cover recent research findings about their mode of action, bioavailabity, interactions with other biological matrices and pharmacokinetics. Moreover, the book gives special attention to the factors that may alter and modulate bioactive compound content, including both cultivation practices and post-harvest treatments that aim towards the production of high quality and healthy foods. Researchers, public health workers, consumers and members of the food industry will find this book to be a useful reference on the variety of phytochemicals present in vegetables.




Agricultural and Food Waste


Book Description

The food processing industries produce millions of tons of losses and waste during processing, which are becoming a grave economic, environmental, and nutritional problem. Fruit, vegetable, and food industrial solid waste include leaves, peels, pomace, skins, rinds pulp, stems, seeds, twigs, and spoiled fruits and vegetables, among other waste released in food production, which can be formed during cleaning, processing, cooking, and/or packaging. These wastes are characterized by being an important source of bioactive compounds, such as phenolic compounds, dietary fibers, polysaccharides, vitamins, carotenoids, pigments, and oils, among others. These bioactive compounds are closely associated with beneficial effects on human health. These by-products can be exploited in different industries: in food industries for the development of functional ingredients and/or new foods or natural additives; in pharmaceutical industries for medicinal, healthcare, or cosmetic products; in agricultural industries as fertilizers or animal feed; and in chemical industries, among others. The reutilization of these by-products will ensure the sustainable development of food industries and reduce their environmental impact, which will contribute to the fight against environmental problems, leading to potential mitigation of climatic change. Therefore, the determination of bioactive compound composition in agricultural and food waste and the production of extracts containing these compounds is the first step towards its reutilization.
