Pesticides are widely used for the control of weeds, diseases, and pests of cultivated plants all over the world, mainly since after Second World War, with the discovery of some organic compounds with good insecticide or herbicide activity. At present, around 2.

  • Representing one of the most important lifestyle factors, diet can strongly influence the incidence and onset of cardiovascular disease and neurodegenerative disorders. Recent dietary intervention studies in several mammalian species, including humans, with flavonoid-rich foods, in particular Vitis vinifera (grape), Camellia sinensis (tea), Theobroma cacao (cocoa), and Vaccinium spp. (blueberry), have indicated an ability of these dietary components to improve memory and learning.

  • The advance of chemicals in industry during the XX century gave rise to a number of highly aggressive compounds to human beings, and that altered the ecosystems balancing. Human population is inevitably exposed to environmental pollution through air-degraded products, water, the soil and food and their introduction into the food chain (Gomez et al, 2011). The use of pesticides has been recognized and accepted as an essential ingredient in the modern agriculture for the control of pests, which damage crops and as a result, they produce a severe loss in food production.

  • This book is written primarily to engineering students in the fields of basic chemistry, environmental chemistry, food production, chemical and biochemical engineering who in the beginning of their university studies receive education in inorganic chemistry and applied chemistry in general. The aim of this book is to explain and clarify important terms and concepts which the students are supposed to be familiar with. The book can not replace existing educational textbooks but it gives a great supplement to the education within chemistry.

  • Preparations derived from Lentinula edodes (Berk.) Pegl. mycelium are worldwide used as dietary supplements containing compounds active as immune system enhancers, demonstrating chemopreventive and anticancer activity. L. edodes mycelium enriched with organic forms of selenium like selenized yeast possess putative, higher cancer preventive properties. The objective of this study was to test the effect of enrichment in selenium on antioxidant, reducing and free radical scavenging activity of water and alcohol extracts from mycelium of L. edodes (Berk.).

  • Prior to the availability of refrigeration, foods, particularly fish and meat, were preserved by salting, marinating or pickling. Through a decrease in water activity, meat and fish were protected against microbial spoilage and other deteriorative processes. It was the process of treating meat with rock salt that led to modern curing practices (Cassens 1990). Thus, meat curing, historically defined as the addition of salt (sodium chloride) to meat, is now referred to as the intentional addition of nitrite and salt to meat.

  • Sustainable agriculture aims to supply sufficient food for the world population while minimizing environmental impact. Part of sustainable agriculture is the application of insecticides in order to protect crops from deleterious inverte- brate pests, feeding on plants cultivated for human consumption. The discovery of neonicotinoid insecticides can be considered as a milestone in insecticide research. 1 Neonicotinoids represent the fastest-growing class of insecticides introduced to the market since the commercialization of pyrethroids....

  • Telomeres, located at the ends of linear chromosomes, are essential for genome stability and integrity. Advances in telomere researches have linked telomere dysfunction with cellular aging and a number of age-related human diseases. Recent studies further expanded our knowledge of telomere functions - telomeres are shown to be important for microbial pathogen virulence and telomere proteins have important non-telomeric cellular functions.

  • It is evident that insecticides have been used to boost food production to a considerable extent and to control vectors of disease. However, these advantages that are of great economic benefits sometimes come with disadvantages when subjected to critical environmental and human health considerations. Many insecticides are newly synthesized whose health and environmental implications are unknown.

  • The market for organic food has increased considerably over the last decade due to consumer’s increasing awareness of both health and environmental issues (Soler et al., 2008). This growth in demand is expected to continue in the coming years, even though the situation differs from one country to another in term of type and quantities of production (Vindigni et al., 2002). The future of organic will, to a large extent, depend on consumer demand.
