Aroma biotechnology opens access to natural volatile flavors. Due to the attribute of "naturalness" these aromas are the most valuable ingredients for foods, cosmetics and related products. The author describes biocatalyzed reactions and biogenetic routes leading to aroma and flavor compounds and he depicts in detail their utilisation in industrial scale processes. All the important topics, including de-novo-synthesis, genetic engineering, in vitro rDNA methods, laboratory requirements and techniques, upscaling, product recovery, profitability, and legal aspects are covered. R.G. Berger contributes his own experimental experience to all except one chapter and leads the reader into state-of-the-art aroma biotechnology.
Throughout history, human beings have sought ways to enhance the flavor of the foods they eat. In the 21st century, biotechnology plays an important role in the flavor improvement of many types of foods. This book covers many of the biotechnological approaches currently being applied to flavor enhancement. The contribution of microbial metabolism to flavor development in fermented beverages and dairy products has been exploited for thousands of years, but the recent availability of whole genome sequences of the yeasts and bacteria involved in these processes is stimulating targeted approaches to flavor enhancement. Chapters discuss recent developments in the flavor modification of wine, beer, and dairy products through the manipulation of the microbial species involved. Biotechnological approaches to the production of specific flavor molecules in microbes and plant tissue cultures, and the challenges that have been encountered, are also covered, along with the metabolic engineering of food crops for flavor enhancement - also a current area of research. Biotechnology is also being applied to crop breeding through marker-assisted selection for important traits, including flavor, and the book looks at the application of the biotechnological approach to breeding for enhanced flavor in rice, apple, and basil. These techniques are subject to governmental regulation, and this is addressed in a dedicated chapter. This updated second edition features five brand new chapters, and the topics covered in the book will be of interest to those in the flavor and food industries as well as to academic researchers interested in flavors.
Over the period of last two decades, there has been significant resurgence in solid-state fermentation due to the numerous benefits it offers, especially in the engineering and environmental aspects. SSF has shown much promise in the development of several bioprocesses and products. This resurgence gained further momentum during the last 5-6 years with the developments in fundamental and applied aspects. A good deal of information has been generated in published literature and patented information. Several commercial ventures have come up based on SSF in different parts of the world. The contents are organized into four parts: Part 1 deals with the General and Fundamentals aspects of SSF; Part 2 deals with the production of bulk chemicals and products such as enzymes, organic acids, spores and mushrooms in SSF; Part 3 is on the use of SSF for specialty chemicals such as gibberellic acid, antibiotics and other pharmaceutically valuable secondary metabolites, pigments, and aroma compounds; Part 4 deals with the use of SSF miscellaneous application such as SSF for food and feed applications, agro-industrial residues as substrates in SSF and the production of silage and vermicompost.
Discussing the biotechnology of aroma compounds, this work includes coverage of: enzymes and flavour biotechnology; glycoconjugated aroma compounds - occurence, role and biotechnological transformation; and prospects for the bioengineering of isoprenoid biosynthesis.
Advances in Grape and Wine Biotechnology is a collection of fifteen chapters that addresses different issues related to the technological and biotechnological management of vineyards and winemaking. It focuses on recent advances in the field of viticulture with interesting topics such as the development of a microvine model for research purposes, the mechanisms of cultivar adaptation and evolution in a climate change scenario, and the consequences of vine water deficit on yield components. Other topics include the metabolic profiling of different Saccharomyces and non-Saccharomyces yeast species and their contribution in modulating the sensory quality of wines produced in warm regions, the use of new natural and sustainable fining agents, and available physical methods to reduce alcohol content. This volume will be of great interest to researchers and vine or wine professionals.
This book is an introduction to the world of aroma chemicals, essential oils, fragrances and flavour compositions for the food, cosmetics and pharmaceutical industry. Present technology, the future use of resources and biotechnological approaches for the production of the respective chemical compounds are described. The book has an integrated and interdisciplinary approach on future industrial production and the issues related to this topic.
Lactic acid bacteria (LAB) have historically been used as starter cultures for the production of fermented foods, especially dairy products. Over recent years, new areas have had a strong impact on LAB studies: the application of omics tools; the study of complex microbial ecosystems, the discovery of new LAB species, and the use of LAB as powerhouses in the food and medical industries. This second edition of Biotechnology of Lactic Acid Bacteria: Novel Applications addresses the major advances in the fields over the last five years. Thoroughly revised and updated, the book includes new chapters. Among them: The current status of LAB systematics; The role of LAB in the human intestinal microbiome and the intestinal tract of animals and its impact on the health and disease state of the host; The involvement of LAB in fruit and vegetable fermentations; The production of nutraceuticals and aroma compounds by LAB; and The formation of biofilms by LAB. This book is an essential reference for established researchers and scientists, clinical and advanced students, university professors and instructors, nutritionists and food technologists working on food microbiology, physiology and biotechnology of lactic acid bacteria.
Consumer product acceptance and market success are dependent on the product's aroma/flavour. Flavours can be produced through chemical synthesis, microbial biocatalysis or by extraction from plants and animal sources. In recent times, chemical synthesis is not as desirable as this is not eco-friendly. So, in the food industry, natural ingredients are added to preparations for efficiency, softness or emotional appeal. Microbiology, bioengineering and biochemistry have enabled the elucidation of metabolic pathways; genetic engineering is expected to help in identifying metabolic blockages and creating novel high-yielding strains, while proteomics help in the application of analytical techniques. All these sciences, old and new, will lead to innovative ideas in the quest for better, sustainable and consumer-approved flavours and aromas.
