Polyphenols are one of the most widespread group of antioxidants found in our diet. In recent years, growing evidence has shown that these powerful antioxidants could protect against many chronic diseases including diabetes, hypertension and cardiovascular disease. This book describes a series of in vitro, animal and humans studies conducted with the aim of investigating the effect of polyphenol-rich green coffee bean extract and dark chocolate on biomarkers of glucose metabolism, blood pressure and lipid profile in overweight and obese individuals. It shows that polyphenol-rich green coffee bean extract and dark chocolate could counteract some of the health problems seen in overweight and obesity, thus highlighting a potential role for these food products in preventing overweight and obesity-related complications.
Polyphenols are the most abundant antioxidants in the diet and are widespread constituents of fruits, vegetables, dry legumes, chocolate, and beverages. The products manufactured from fruits also contain polyphenols in significant amounts. Typically a glass of red wine or a cup of tea or coffee contains about 100 mg polyphenols. Polyphenols or polyphenol rich diets provide significant protection against the development and progression of many chronic pathological conditions including diabetes, cardio-vascular and neurodegenerative diseases or osteoporosis. Our research is focused on the benefits of polyphenols extracted from the black grapes seeds (BGSP), Sambucus nigra or Aronia melanocarpa fruits by using as experimental model the streptozotocin-induced diabetes mellitus on the Wistar white rats. The results of our studies presented in this paper provide a current understanding on the biological effects of polyphenols and their relevance to health. The role of polyphenols in human health is still a less known area of research as polyphenols have proven to offer great hope for the prevention of chronic human diseases.
Living organisms are exposed to a range of oxidizing species which have the potential to damage bio-molecules. Antioxidants protect cellular systems from potentially harmful effects of processes that cause excessive oxidation. The effect of free radicals on proliferating human and rat peripheral lymphocytes and scavenging effect of green tea polyphenols were studied. Exposure to Green tea Polyphenols (low concentration) induced an antioxidant defense mechanism in human and rat peripheral lymphocytes and rat liver.Green tea polyphenols also induce to increase the values of antioxidant defense system of cells such as SOD, POD and Catalase.further more the level of Reduced Glutathione was found to restore to an extent by treatment with polyphenols at low concentration

This book provides an overview of the science and technology of chocolate manufacture from cocoa production, through the manufacturing processes, to the sensory, nutrition and health aspects of chocolate consumption. It covers cocoa cultivation and production with special attention paid to cocoa bean composition, genotypic variations in the bean, post-harvest pre-treatments, fermentation and drying processes, and the biochemical basis of these operations. The scientific principles behind industrial chocolate manufacture are outlined with detailed explanations of the various stages of chocolate manufacturing including mixing, refining, conching and tempering. Other topics covered include the chemistry of flavour formation and development during cocoa processing and chocolate manufacture; volatile flavour compounds and their characteristics and identification; sensory descriptions and character; and flavour release and perception in chocolate. The nutritional and health benefits of cocoa and chocolate consumption are also addressed. There is a focus throughout on those factors that influence the flavour and quality characteristics of the finished chocolate and that provide scope for process optimization and improvement. The book is designed to be a desk reference for all those engaged in the business of making and using chocolate worldwide; confectionery and chocolate scientists in industry and academia; students and practising food scientists and technologists; nutritionists and other health professionals; and libraries of institutions where food science is studied and researched. an overview of the science behind chocolate manufacture covers the whole process from cocoa production, through manufacturing, to the nutrition and health aspects of chocolate consumption focuses on factors that influence chocolate flavour and quality, and that provide scope for process optimization and improvement.
Coffee pulp is one of the most abundantly available agro-industrial wastes, produced during the pulping o Thus, for every 2 tonnes coffee cherries processed, nearly one ton pulp is generated . Only the coffee bean has a real commercial value. It represents 55.4% of the fruit on dry weight basis and the rest is considered to be the byproducts or residues. At different stages from harvesting to the processing and consumption, several residues viz., coffee pulp or husk, leaves and spent-ground are generated in more than two million tonnes quantity yearly . Among these byproducts, coffee pulp is the most important. Operation of the coffee cherries to obtain coffee beans in many coffee-producing areas of the tropics.The use of raw coffee pulp has been suggested to be lower than 20% in ruminant diets due to the presence of caffeine, tannins and other polyphenols. Solid- state fermentation technique was adopted earlier for protein enrichment of coffee-pulp using different strains of Aspergillus sp. Later it was proposed that desirable biochemical changes in terms of higher nitrogen content
