Although organic acids have been used to counteract pathogens in food for many years, there is a glaring need to assess and improve their continued effectiveness and sustainability. There is also a growing demand for foods that are produced using milder treatments (e.g., less heat, salt, sugar, and chemicals) and newer technologies to prevent the g

Book Description
For centuries man has treated food to prolong its edible life, and nowadays both traditional and modern preservatives are used widely to ensure the satisfactory maintenance of quality and safety of foods. There continues to be increased public concern about the use of food additives, including preservatives, resulting from a perception that some of them may have deleterious effects on health. However, as eating habits have changed with an emphasis on what has been popularly termed a `healthy diet', there is at the same time a concern that reduction in preservative usage could lead to loss of safety and protection from food poisoning. While some preservatives are coming under increasing regulatory pressure others, particularly more natural ones, are receiving increased attention and gaining in importance and acceptability. This book supports the continued safe and effective use of preservatives within these current constraints. It therefore gives detailed information on the practical use of the major antimicrobial preservatives. Uniquely, it couples this with current understanding of their modes of action, at the levels of cellular physiology and biochemistry, in such a way as to provide a sound scientific basis for their efficacy. Such an approach also encourages the future logical development and use of preservatives.

Book Description
Organic acids are compounds with acidic properties and occur naturally in a number of foods. They are mainly present in fermented products as a result of hydrolysis, biochemical metabolism, and microbial activity. This book provides research on the characteristics, properties and synthesis of organic acids. Chapter One reviews the application of organic acids in food preservation. Chapter Two provides a chromatographic analysis organic acids in food from animal origin. Chapter Three discusses the diversity of organic acids content in green and roasted Coffea arabica cultivars. Chapter Four studies the effects of organic acids and polysaccharides on the solubility of oyster-derived zinc digested in vitro. Chapter Five examines the evaporation of organic acids aqueous solutions through spread films of polyelectrolyte/surfactant complexes. Chapter Six discusses the influence of liquid absorption and the effect of downstream pressure on the separation performance of pervaporation of acetic acid aqueous solutions.

Book Description
The processing of food is no longer simple or straightforward, but is now a highly inter-disciplinary science. A number of new techniques have developed to extend shelf-life, minimize risk, protect the environment, and improve functional, sensory, and nutritional properties. The ever-increasing number of food products and preservation techniques cr

Book Description
Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

Book Description
This book covers application of food microbiology principles into food preservation and processing. Main aspects of the food preservation techniques, alternative food preservation techniques, role of microorganisms in food processing and their positive and negative features are covered. Features subjects on mechanism of antimicrobial action of heat, thermal process, mechanisms for microbial control by low temperature, mechanism of food preservation, control of microorganisms and mycotoxin formation by reducing water activity, food preservation by additives and biocontrol, food preservation by modified atmosphere, alternative food processing techniques, and traditional fermented products processing. The book is designed for students in food engineering, health science, food science, agricultural engineering, food technology, nutrition and dietetic, biological sciences and biotechnology fields. It will also be valuable to researchers, teachers and practising food microbiologists as well as anyone interested in different branches of food.

Book Description
It is estimated that foodborne microorganisms in the United States cause 48 million sicknesses, 128,000 hospitalizations and 3,000 deaths each year. Food spoilage due to decay-causing microorganisms is also an issue in both developing and developed countries with 30-40% annual loss of fruits and vegetables. Synthesized antimicrobials (preservatives) are commonly used by the food industry to enhance microbial safety and increase shelf-life. However, food and agricultural industries are experiencing a lack of potent antimicrobial agents to secure the safety and maintain the quality of food products. Some synthetic preservatives may produce harmful by-products and damage the environment. There is also increasing incidence of antibiotics-resistant pathogens which has drawn great concern from the scientific communities and public health professionals. Therefore, there is increasing interest in the use of natural antimicrobials to enhance microbial safety, reduce spoilage and extend the shelf life of food. Natural antimicrobials are from plants, microorganisms and animals. They cover a wide variety of compounds including phenolics, terpenes, bacteriocins, peptides, proteins, natural polymers, fatty acids (lipids), and organic acids. Overall reviews of well-known natural or bio-based antimicrobials are first presented. The book then discusses antimicrobials of plant sources and their applications in foods and animal health. A number of chapters address the combinations of natural antimicrobials with non-thermal processing technologies to achieve additive and synergistic effects. The use of natural antimicrobials in packaging and coating, as well as both well-studied and novel biobased antimicrobials are discussed. Furthermore, the needs for toxicological evaluations of natural and bio-based antimicrobials are presented and protocols are recommended. Moreover, there is discussion in many of the chapters on the modes of action, mechanisms, and industrial aspects of applying natural or bio-based antimicrobials.
