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.
With increasing consumer preference for natural foods, biological production of food ingredients is more important than ever before. This book is an in-depth review of bioprocess production of flavor, fragrance, and color ingredients, including esters, aldehydes, lactones, pyrazines, terpenoids, dairy flavors such as methyl ketones, and savory flavors such as HVPs, nucleotides, yeast autolysates, and extracts. Technologies of interest to the food and flavor industry are also covered, including genetic engineering and plant tissue culture, with specific examples taken from flavors and fragrances. Additionally, one entire chapter is devoted to nontechnical issues such as regulation of biotechnology products in foods, consumer perception of the new biotechnology, definition and importance of the word natural, and other related issues. Presentation is practical, down-to-earth, and applicable by food, flavor, and fragrance industry professionals.
Highlights the impact of biotechnology on the food industry and discusses strategies for producing new and improved raw materials. Details the latest analytical methodology for characterizing products generated by biotechnology. Describes the generation of flavors from precursors via enzymes and microorganisms. Discusses the construction of chimeric enzymes with improved properties. Reviews the effect of new plant crop regulators on crop yield and quality.
The second edition stands as the most authoritative reference for natural ingredients in commercial use. It encompasses approximately 500 of the most commonly used ingredients, and covers the identification, processing, preparation, and manner of use for each. This volume emphasizes the drugs and herbal formulations created for those purposes. It updates all the original entries of the first edition, and incorporates many new entries, classifications, references, and a new category, Health Foods/Herbal Teas. The features include In-depth coverage of each ingredient, including general description, chemical composition, uses and commercial preparations, and synonyms, as well as regulatory status and references; An easily accessible alphabetical presentation of the entries according to common names, and cross-referenced to scientific names in the index; Glossary of the most commonly encountered terms used in the botanical industry.
The Food Chemicals Codex is the accepted standard for defining the quality and purity of food chemicals. It is frequently referenced by the U.S. Food and Drug Administration and many international food regulatory authorities. The Fifth Edition updates the field, incorporating the definitive monographs of previous editions with completely new material. Each monograph provides a physical description of the substance and its use in foods, lists its purity requirements, describes the appropriate tests to determine compliance, and provides packaging and storage guidelines.
Examines new analytical techniques to determine authenticity of "natural" fruit flavors, aromas, and essential oils. Describes the biochemical pathways as well as bioconversion of fruit flavors. Reviews the conversion of flavorless precursors to intensely flavored key aroma components in tomatoes, apricots, and apples and describes the effect of packaging and storage on flavor of orange juice, apples, pears, and berries. Describes analytical and sensory characteristics of orange juice, cupuac, carambola, and kiwi fruit flavors and correlates analytical and sensory techniques. Explores the effect that environmental factors, maturity, and variety can have on the quality of fruit products.
This book features updated and expanded information on the role of the flavorist, uses of biotechnology for the production of flavoring material, essential oils, plant materials, and volatile & nonvolatile chemicals used in flavors. It also includes a list of flavoring ingredients & their legal status.
