Microbial Enzymes And Additives For The Food Industry

The growing food industry is currently employing a large number of microbial products. Microbial products are of biological origin and are considered safe as compared to synthetic and chemical formulations. Microbial products are used in the processing or manufacturing of a variety of food products. These days, fermented foods have become very common. Enzymes, pigments, and organic acids of microbial origin are common in the food industry. Demand for microbial products and metabolites are continuously increasing, and microbial products are an area of commercial interest for the food biotechnology and microbial biotechnology industries. This book covers microbial enzymes along with their utilization in the food industry. Important enzymes including amylase, inulinase, pullulanase, protease, aspartase, naringinase, cellulose, xylanase, pectinase, and asparaginase have been discussed, along with their potent applications in the food industry. Also, microbial polysaccharides, organic acids, and pigments of microbial origin have been discussed. This book will provide important insight regarding microbial enzymes and additives for the food industry now and in the future. This text will be helpful for graduate, post graduate students, researchers, and industry professionals, extensively engaged in the area of food science and technology, food biotechnology, and industrial biotechnology.

The aim of food processing is to produce food that is palatable and tastes good, extend its shelf-life, increase the variety, and maintain the nutritional and healthcare quality of food. To achieve favorable processing conditions and for the safety of the food to be consumed, use of food grade microbial enzymes or microbes (being the natural biocatalysts) is imperative. This book discusses the uses of enzymes in conventional and non-conventional food and beverage processing as well as in dairy processing, brewing, bakery and wine making. Apart from conventional uses, the development of bioprocessing tools and techniques have significantly expanded the potential for extensive application of enzymes such as in production of bioactive peptides, oligosaccharides and lipids, flavor and colorants. Some of these developments include extended use of the biocatalysts (as immobilized/encapsulated enzymes), microbes (both natural and genetically modified) as sources for bulk enzymes, solid state fermentation technology for enzyme production. Extremophiles and marine microorganisms are another source of food grade enzymes. The book throws light on potential applications of microbial enzymes to expand the base of food processing industries.

Continuing the very successful first edition, this book reviews the most recent changes to the legal situation in Europe concerning genetically engineered food and labeling. Due to the extremely rapid developments in green biotechnology, all the chapters have been substantially revised and updated. Divided into three distinct parts, the text begins by covering applications and perspectives, including transgenic modification of production traits in farm animals, fermented food production and the production of food additives using filamentous fungi. The second section is devoted to legislation, while the final part examines methods of detection, such as DNA-based methods, and methods for detecting genetic engineering in composed and processed foods. From the reviews of the first edition: "This work promises to be a standard reference in the detection of genetically engineered food. I believe this work will find a valued place for any scientist, regulator or technical library that deals with biotechnology or detection of genetically engineered food organisms." —James J. Heinis, Journal of Agricultural & Food Information

Bioprocessing has been used for a long time in the production of food. In fact, as early as 3,500 B.C., Sumerian brewers were using bioprocessing to create a popular beverage many drinkers still enjoy today. Bioprocessing, as the name suggests, uses living organisms and their components in the creation of new products. Bioprocessing is often used to manufacture pharmaceuticals, sustainable materials, alternative fuels, and even many of the foods we enjoy. Biotechnology as applied to food processing in most developing countries makes use of microbial inoculants to enhance properties such as the taste, aroma, shelf-life, texture and nutritional value of foods. The process whereby micro-organisms and their enzymes bring about these desirable changes in food materials is known as fermentation. Fermentation processing is also widely applied in the production of microbial cultures, enzymes, flavours, fragrances, food additives and a range of other high value-added products. These high value products are increasingly produced in more technologically advanced developing countries for use in their food and non-food processing applications. Many of these high value products are also imported by developing countries for use in their food-processing applications. Food, food-biocatalists and bioprocessing industries face great challenges in order to develop and establish systems to develop high quality, safety foods, as well as feeds and other industrial goods, environmentally acceptable and in a sustainable way. The text is supported by numerous clear informative diagrams. The book would be highly useful to the postgraduate students and researchers of applied biology, biotechnology, microbiology and biochemical engineering.

This book covers all the aspects of food-grade enzymes, including their classification, kinetics, microbial production, biosynthetic pathways, commodity-wise industrial applications, and downstream processing strategies. The broad focus of this book is on the application of various classes of enzymes in dairy, fruits and vegetables, cereals and oilseeds, meat and poultry, and brewing and food packaging industries. Certain recent areas such as nanotechnological perspective in enzyme immobilization, infusion strategies as well as its efficient usage in food packaging and preservation are some of the salient highlights of this book. This book also discusses the aspects related to application of enzymes in functional food development and shelf life extension of various commodities food products. This book is beneficial for researchers, students, entrepreneurs, and industry experts in broad disciplines such as food processing, food biotechnology, food microbiology, biochemistry, agriculture, biotechnology, biochemical engineering, and bioprocess technology.

This book provides all the aspects of microbes for food additives, and a detailed description of their different categories. The chapters provide a step-by-step overview of microbial food additives as enzymes, antioxidants, stabilizers, emulsifiers, organic acids, colorants, sweeteners, flavoring compounds that have been used commercially by industrialists. In addition, an emphasis on the use of microbes as therapeutic agents such as probiotics and enzymes have also been given in the respective chapters. Furthermore, the book also comprises the detailed description of legislation and policies for the use of microbial additives at large scale in different food industries. Therefore, this book provides a comprehensive, state of art updated literature which can be used by the food scientists, nutritionists, microbiologists and a health-conscious layman to check the food additive list on a product for a nutritious and safer food.
