Effects Of Food Processing On Bioactive Compounds

Bioactive Compounds Are Extra-Nutritional Constituents That Typically Occur In Small Quantities In Foods. Many Thousands Of These Bioactive Compounds Have Been Identified In Commonly Eaten Foods And There Has Been A Lot Of Research Interest Into Their Putative Health Benefits. Virtually All Foods Undergo Some Form Of Processing Before They Are Ready For Consumption. Processing Of Fresh Fruits And Vegetables Results In Changes In Composition Of The Bioactive Food Components. These Changes Can Be Beneficial Or Detrimental To The Total Content Of Health-Promoting Phytochemicals. By Adopting Effective Processing And Storage Techniques One Can Retain Bioactive Compounds And Other The Nutrients In The Foods. This Book Examines The Effects Of Food Processing On Bioactive Compounds By Covering A Wide Range Of Products And Examining The Response To Many Different Processing Operations In Regard To Positive Or Negative Effects On Health. This Book Is Intended For Scientists, Nutritionists And Health Practitioners.

Bioactive compounds in food, known for their positive health effects, can be lost during handling after harvest, processing and storage. While most foods are exposed to processing to increase shelf life and edibility and to ensure microbial safety, conventional processing methods may have disadvantages, such as decreasing the nutritional quality of foods, long processing times, high temperature and high energy uses. For these reasons, novel non-thermal food processing technologies (including HPP, ultrasound) and novel thermal food processing technologies (including microwave/Ohmic heating) have become widespread. This book provides a critical evaluation of the effects of conventional, novel non-thermal, and thermal food processing techniques on the retention and bioaccessibility of bioactive compounds in food materials. Within these three categories, many different processing methods are included: fermentation/germination, drying, extrusion, and modified atmosphere packaging, as well as novel technologies, such as microwave heating, ultrasound, high pressure processing, ozonation, and membrane separation processes.

This text examines bioactive compounds as food is processed - covering a wide range of products and examining the response to many different processing operations in regard to positive or negative effects on health.

Functional foods are foods which contain bioactive components, either from plant or animal sources, which can have health benefits for the consumer over and above their nutritional value. Foods which have antioxidant or cancer-combating components are in high demand from health conscious consumers: much has been made of the health-giving qualities of fruits and vegetables in particular. Conversely, foods which have been processed are suffering an image crisis, with many consumers indiscriminately assuming that any kind of processing robs food of its “natural goodness”. To date, there has been little examination of the actual effects – whether positive or negative – of various types of food processing upon functional foods. This book highlights the effects of food processing on the active ingredients of a wide range of functional food materials, with a particular focus on foods of Asian origin. Asian foods, particularly herbs, are becoming increasingly accepted and demanded globally, with many Western consumers starting to recognize and seek out their health-giving properties. This book focuses on the extraction of ingredients which from materials which in the West are seen as “alternative” - such as flour from soybeans instead of wheat, or bran and starch from rice – but which have long histories in Asian cultures. It also highlight the incorporation of those bioactive compounds in foods and the enhancement of their bioavailability. Functional Foods and Dietary Supplements: Processing Effects and Health Benefits will be required reading for those working in companies, research institutions and universities that are active in the areas of food processing and agri-food environment. Food scientists and engineers will value the new data and research findings contained in the book, while environmentalists, food regulatory agencies and other food industry personnel involved in functional food production or development will find it a very useful source of information.
