Concerns and potential risks regarding the use of synthetic chemicals have renewed the interests of consumers using natural and safe alternatives. Plant extracts represent an interesting ingredient, mainly due to their natural origin and phytochemical properties, allowing for obtaining active materials to extend shelf-life and add value to the product. Plant Extracts in Food Applications is the first book of its kind focusing on application of plant extracts in the food industry and covers; sources, extraction and encapsulation techniques, chemistry and stability of plant extracts; antimicrobials, preservatives, nutrient enhancers, enzymes, flavoring and coloring agents, packaging aid, Health benefits and opportunities and challenges of plant extracts to use in food applications. Written by several experts in the field, this book is a valuable resource for students, scientists, and professionals in food science, food chemistry and nutrition. Presents chapters that deal with different sources of plant extracts and their applications in food industry Covers the various extraction procedures which are used for plant extracts Includes health benefits and stability of plant extracts Provides role of plant extracts as shelf life enhancement, packaging aid, flavouring and colouring agent
Free radicals are atoms or molecules containing unpaired electrons. Damage occurs when the free radical encounters another molecule and seeks to find another electron to pair its unpaired electron. Free radicals can cause mutation in different biological compounds such as protein, nucleic acids, and lipids, and the damage caused by the free radicals lead to various diseases (cancer, cardiovascular disease, aging, etc.). Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons, which neutralize the radical without forming another. Ascorbic acid, for example, can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule. Unfortunately, new data indicate that the synthetic antioxidants used in the industry could have carcinogenic effects on human cells, thus fueling an intense search for new, natural, and efficient antioxidants. Therefore, the current book discusses the role and source of antioxidant compounds in nutrition and diets. Also, the current book includes nine chapters contributed by experts around the world, and the chapters are categorized into two sections: "Antioxidant Compounds and Biological Activities" and "Natural Antioxidants and Applications."

Natural additives are increasingly favoured over synthetic ones as methods of ensuring food safety and long shelf-life. The antimicrobial properties of both plant-based antimicrobials such as essential oils and proteins such as bacteriocins are used in, for example, edible preservative films, in food packaging and in combination with synthetic preservatives for maximum efficacy. New developments in delivery technology such as nanoencapsulation also increase the potential of natural antimicrobials for widespread use in industry. Part one introduces the different types of natural antimicrobials for food applications. Part two covers methods of application, and part three looks at determining the effectiveness of natural antimicrobials in food. Part four focuses on enhancing quality and safety, and includes chapters on specific food products. Reviews different types of antimicrobials used in food safety and quality Covers how antimicrobials are created to be used in different foods Examines how the antimicrobials are used in foods to enhance the safety and quality

Recent major shifts in global health care management policy have been instrumental in renewing interest in herbal medicine. However, literature on the development of products from herbs is often scattered and narrow in scope. Herbal Bioactives and Food Fortification: Extraction and Formulation provides information on all aspects of the extraction of biological actives from plants and the development of dietary supplements and fortified food using herbal extracts. The book begins with a brief survey of the use of herbs in different civilizations and traces the evolution of herbal medicine, including the emergence of nutraceuticals from the discipline of ethnopharmacology and the Alma Ata Declaration of 1978. It moves on to describe various aspects of the extraction process, including selection of plant species, quality control of raw materials, the comminution of herbs, and the selection of solvents. It also describes the optimization of extraction in relation to response surface methodology before describing uses of herbal extracts in food supplements and fortified foods. With special attention paid to stability analysis and the masking of tastes, the book gives an overview of the formulation of various types of tablets, capsules, and syrups using herbal extracts. It also describes the benefits of foods fortified with herbal extracts such as soups, yogurt, sauces, mayonnaise, pickles, chutneys, jams, jellies, marmalades, cheese, margarine, sausages, bread, and biscuits, as well as some beverages. Herbal Bioactives and Food Fortification covers the fundamental steps in herbal extraction and processing in a single volume. It explains how to choose, optimize, analyze, and use extracts for fortification, making it an excellent source for nutraceutical researchers and practitioners in science and industry.
Twelve years have passed since its last edition - making Antimicrobials in Foods, Third Edition the must-have resource for those interested in the latest information on food antimicrobials. During that time, complex issues regarding food preservation and safety have emerged. A dozen years ago, major outbreaks of Escherichia coli O157:H7 and Listeria monocytogenes had not yet occurred, consumer and regulatory demands for improved food safety were just surfacing, the use of naturally occurring antimicrobials was in its infancy, and lysozyme, lactoferrin, ozone, and several other compounds were not approved for use in or on foods in the United States. The editors have addressed these contemporary topics by synthesizing information from internationally recognized authorities in their fields. Five new chapters have been added in this latest release, including the most recent details on lysozyme, naturally occurring antimicrobials from both animal and plant sources, hurdle technology approaches, and mechanisms of action, resistance, and stress adaptation. Existing chapters have been extensively revised to reflect the most relevant research and information available on antimicrobials. Complementing these topics is information on the progress that has been made in determining the effects and mechanisms of action involved in a number of naturally occurring antimicrobials.

Nature has always been, and still is, a source of food and ingredients that are beneficial to human health. Nowadays, plant extracts are increasingly becoming important additives in the food industry due to their antimicrobial and antioxidant activities that delay the development of off-flavors and improve the shelf life and color stability of food products. Due to their natural origin, they are excellent candidates to replace synthetic compounds, which are generally considered to have toxicological and carcinogenic effects. The efficient extraction of these compounds from their natural sources and the determination of their activity in commercialized products have been great challenges for researchers and food chain contributors to develop products with positive effects on human health. The objective of this Special Issue is to highlight the existing evidence regarding the various potential benefits of the consumption of plant extracts and plant-extract-based products, with emphasis on in vivo works and epidemiological studies, the application of plant extracts to improving shelf life, the nutritional and health-related properties of foods, and the extraction techniques that can be used to obtain bioactive compounds from plant extracts.
