Polyphenols make a vital contribution to the colour, tanning, taste and astringency of so many of society's favourites - from the unique taste of the British cup of tea to a glass of red wine. Found widely in many foods of plant origin, polyphenols are also becoming increasingly recognised as antioxidants in the body, with action on long-term health and reduction in the risk of chronic disease. Due to the importance of polyphenols, it is vital to conduct accurate and sensitive analysis. Providing detailed state-of-the-art research, presented in a practical and effective way, Methods in Polyphenol Analysis looks at the latest techniques in this developing field and includes, among others: New modern techniques, such as LC-MS, LC-NMR and LC-coulometric detection; Chemical and enzymatic synthesis of polyphenol conjugates; and Characterization of oligomeric and polymeric tannins and complex polyphenols. This timely publication is written by highly experienced practitioners in this field and will be invaluable to all academics and industrialists involved in phytochemistry, biochemistry and food science.

Food additives play a vital role in allowing food manufacturers to provide the range of foods that are available in the developed countries of the world. Additives cover a considerable range from the recognisable sodium bicarbonate used to make cakes in the domestic kitchen to mono- and di-acetyltartaric esters of mono- and diglycerides of fatty acids used as emulsifiers in commercial bread production. They include curcumin, the yellow colour in turmeric, beeswax and citric acid, the acid in citrus fruit, as well as substances prepared synthetically. It has long been fashionable in the media to criticise additives and, in so doing, to lump them all together but this ignores their diversity, their vital role in food production and preservation and the extensive testing they have undergone before being approved. This book outlines why additives are used, the testing regime within Europe, and a complete listing of all additives permitted within the EU. The law covering food additives in the EU, which was harmonised in 1989, has been revised a number of times, most recently by the publication of Regulations 1333/2008 and 1129/2011. These Regulations have been amended a number times with additives being removed or added. This fifth edition of the Guide brings it up to date with a revision of every chapter to reflect the current situation. Providing an invaluable resource for food and drink manufacturers, this book is the only work covering in detail every additive, its sources and uses. Those working in and around the food industry, students of food science and indeed anyone with an interest in what is in their food will find this a practical book full of fascinating details.

Food additives have played and still play an essential role in the food industry. Additives span a great range from simple materials like sodium bicarbonate, essential in the kitchen for making cakes, to mono- and diglycerides of fatty acids, an essential emulsifier in low fat spreads and in bread. It has been popular to criticise food additives, and in so doing, to lump them all together, but this approach ignores their diversity of history, source and use. This book includes food additives and why they are used, safety of food additives in Europe, additive legislation within the EU and outside Europe and the complete listing of all additives permitted in the EU. The law covering food additives in the EU which was first harmonised in 1989 has been amended frequently since then, but has now been consolidated with the publication of Regulations 1331/2008 and 1129/2011. This 4th edition of the Guide brings it up to date with the changes introduced by this legislation and by the ongoing review of additives by EFSA. Providing an invaluable resource for food and drink manufacturers, this book is the only work covering in detail every additive, its sources and uses. Those working in and around the food industry, students of food science and indeed anyone with an interest in what is added to their food will find this a practical book full of fascinating details.
