Book Synopsis E-Cigarette Use Among Youth and Young Adults: a Report of the Surgeon General by : Centers for Disease Control and Prevention
Download or read book E-Cigarette Use Among Youth and Young Adults: a Report of the Surgeon General written by Centers for Disease Control and Prevention and published by . This book was released on 2019-07-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tobacco use among youth and young adults in any form, including e-cigarettes, is not safe. In recent years, e-cigarette use by youth and young adults has increased at an alarming rate. E-cigarettes are now the most commonly used tobacco product among youth in the United States. This timely report highlights the rapidly changing patterns of e-cigarette use among youth and young adults, assesses what we know about the health effects of using these products, and describes strategies that tobacco companies use to recruit our nation's youth and young adults to try and continue using e-cigarettes. The report also outlines interventions that can be adopted to minimize the harm these products cause to our nation's youth.E-cigarettes are tobacco products that deliver nicotine. Nicotine is a highly addictive substance, and many of today's youth who are using e-cigarettes could become tomorrow's cigarette smokers. Nicotine exposure can also harm brain development in ways that may affect the health and mental health of our kids.E-cigarette use among youth and young adults is associated with the use of other tobacco products, including conventional cigarettes. Because most tobacco use is established during adolescence, actions to prevent our nation's young people from the potential of a lifetime of nicotine addiction are critical.E-cigarette companies appear to be using many of the advertising tactics the tobacco industry used to persuade a new generation of young people to use their products. Companies are promoting their products through television and radio advertisements that use celebrities, sexual content, and claims of independence to glamorize these addictive products and make them appealing to young people.

Book Synopsis Headspace Analysis of Foods and Flavors by : American Chemical Society. Meeting
Download or read book Headspace Analysis of Foods and Flavors written by American Chemical Society. Meeting and published by Springer Science & Business Media. This book was released on 2001-08-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headspace gas analysis is an analytical technique that has been successfully applied to food flavors for over 20 years but has experienced a resurgence of interest and innovation in recent years. In its truest form, headspace analysis represents the direct collection and analysis of the mixture of vapors in the space immediately above a food or beverage. The technique offers several advantages for workers interested in how a product smells and ultimately tastes. It offers the advantages of speed, simplicity, and, more importantly, represents the aroma profile a consumer is likely to experience just before consuming the product. Since only volatile components are collected, the sample is totally free of nonvolatile residues which commonly plague comparison liquid-liquid extracts of the same product. This is the first book devoted to headspace analysis in foods and beverages in more than 20 years. The publication contains chapters on the basic theory of headspace analysis, as well as the theory and application of newly developed headspace techniques, such as solid phase micro extraction, SPME and electronic noses. New concentrating and desorption techniques are described in addition to a raft of food applications including tomato and citrus juices, alcoholic beverages, baguettes, dairy products, lipids, grill flavoring, baked potato, and meat. Chapters on off-flavors as well as aroma-food matrix interactions are also included. "This is the bible of headspace analysis. If you are involved in, or planning on becoming involved, or want to learn more about, this incredible subject , then buy this book immediately!" – Aubrey Parsons, governing council member, International Union for Food Science and Technology

Book Synopsis Public Health Consequences of E-Cigarettes by : National Academies of Sciences, Engineering, and Medicine
Download or read book Public Health Consequences of E-Cigarettes written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.

Book Synopsis Food Authentication by : Contantinos A. Georgiou
Download or read book Food Authentication written by Contantinos A. Georgiou and published by John Wiley & Sons. This book was released on 2017-05-08 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of food authenticity is a vital component of quality control. Its importance has been highlighted in recent years by high-profile cases in the global supply chain such as the European horsemeat scandal and the Chinese melamine scandal which led to six fatalities and the hospitalisation of thousands of infants. As well as being a safety concern, authenticity is also a quality criterion for food and food ingredients. Consumers and retailers demand that the products they purchase and sell are what they purport to be. This book covers the most advanced techniques used for the authentication of a vast number of products around the world. The reader will be informed about the latest pertinent analytical techniques. Chapters focus on the novel techniques & markers that have emerged in recent years. An introductory section presents the concepts of food authentication while the second section examines in detail the analytical techniques for the detection of fraud relating to geographical, botanical, species and processing origin and production methods of food materials and ingredients. Finally, the third section looks at consumer attitudes towards food authenticity, the application of bioinformatics to this field, and the Editor’s conclusions and future outlook. Beyond being a reference to researchers working in food authentication it will serve as an essential source to analytical scientists interested in the field and food scientists to appreciate analytical approaches. This book will be a companion to under- and postgraduate students in their wander in food authentication and aims to be useful to researchers in universities and research institutions.
Book Synopsis Volatiles and Food Security by : Devendra K. Choudhary
Download or read book Volatiles and Food Security written by Devendra K. Choudhary and published by Springer. This book was released on 2017-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents research on volatiles produced by microbes and plants along with their biotechnological implications for sustainable agriculture. A greater understanding of how plants and microbes live together and benefit each other can provide new strategies to improve plant productivity, while at the same time helping to protect the environment and maintain global biodiversity. To date, the use of chemicals to enhance plant growth or induced resistance in plants has been limited due to the negative effects and the difficulty in determining the optimal concentrations to benefit the plant. The book discusses extensive studies on biological alternatives that avoid these problems, and the research presented suggests that these compounds could offer an environmentally sound means to better grow and protect plants under greenhouse or field conditions. To understand the nature of VOCs and gene expression profiling of plant genes responding against these compounds can be conducted. It is possible that VOCs produced by microbes while colonizing roots are generated at sufficient concentrations to trigger plant responses. In conclusion, positive or negative effects of VOCs on plant productivity will be dependent on upon specific VOCs microbial strain, plant genotype, and presence/absence of abiotic/biotic stresses
