Genre: Technology & Engineering

Stabilisers, thickeners and gelling agents are extracted from a variety of natural raw materials and incorporated into foods to give the structure, flow, stability and eating qualities desired by consumers. These additives include traditional materials such as starch, a thickener obtained from many land plants; gelatine, an animal by-product giving characteristic melt-in-the-mouth gels; and cellulose, the most abundant structuring polymer in land plants. Seed gums and other materials derived from sea plants extend the range of polymers. Recently-approved additives include the microbial polysaccharides of xanthan, gellan and pullulan. This book is a highly practical guide to the use of polymers in food technology to stabilise, thicken and gel foods, resulting in consistent, high quality products. The information is designed to be easy to read and assimilate. New students will find chapters presented in a standard format, enabling key points to be located quickly. Those with more experience will be able to compare and contrast different materials and gain a greater understanding of the interactions that take place during food production. This concise, modern review of hydrocolloid developments will be a valuable teaching resource and reference text for all academic and practical workers involved in hydrocolloids in particular, and food development and production in general.

Genre: Technology & Engineering

The sucess of the first edition of Thickening and Gelling Agents for Food underlined the keen interest in functional food ingredients. In this second edition, the text has been completely revised and updated to reflect the current market trends. New chapters have been included to broaden the scope of materials used by the food technologist. Agar and konjac gum (flour), probably the most traditional gelling and thickening agents, but most widely utilised in the Far East, have been given greater prominence. Microcrystalline cellulose, a relatively new food stabiliser used widely in the USA, has been included. The preparation of traditional products using formulations suited to bulk food processings is described while new areas focus on low fat and low calorie foods where there is an even greater demand for controlling the stability, viscosity, gelation and mouthfeel using a broad range of thickening and gelling agents. Recent legislative changes in the USA and EC impact the use of additives including gellan gum, konjac flour, carrageenan, tara gum and microcrystal line cellulose: some changes have increased the number of additives ap proved for foods, while others allow a broader range of materials to be used in foods. The detailed information on products, properties and applications given in this second edition will enable these highly functional thickening and gelling agents to be used to full advantage.

Engineering Aspects of Food Biotechnology

Author: Jose A. Teixeira
Publisher: CRC Press
ISBN: 9781439895467
Release Date: 2013-08-29
Genre: Technology & Engineering

Food biotechnology’s typical developments and applications have occurred in the fields of genetics and in enzyme- and cell-based biological processes, with the goal of producing and improving food ingredients and foods themselves. While these developments and applications are usually well reported in terms of the underlying science, there is a clear lack of information on the engineering aspects of such biotechnology-based food processes. Filling this gap, Engineering Aspects of Food Biotechnology provides a comprehensive review of those aspects, from the development of food processes and products to the most important unit operations implied in food biotechnological processes, also including food quality control and waste management. The book focuses on the use of biotechnology for the production of ingredients to be used in the food industry. It addresses two relevant issues—consumer’s awareness of the relation between nutrition and good health and the importance of environmental sustainability in the food chain (i.e. production of polymers and in vitro meat). A chapter on the application of process analytical technology highlights the importance of this tool for satisfying the increasingly sophisticated and strict polices for quality control and monitoring of specific process phases. The book includes a detailed presentation of relevant unit operations developed to extract/purify the ingredients of biotechnological origin intended for food applications. In addition to examining the contributions of biotechnology to producing and improving food ingredients, the book provides a concise description of the role biotechnology plays in adding value to food processing by-products, including post-harvest losses, in relevant industries of the food sector. It builds a foundation for further research and development in the food processing industry.

Practical Food Rheology

Author: Ian T. Norton
Publisher: John Wiley & Sons
ISBN: 1444391054
Release Date: 2010-12-01
Genre: Technology & Engineering

Rheology is fundamentally important in food manufacturing in two major senses. Understanding the way in which a substance moves and behaves is essential in order to be able to transport and mix it during processing. Secondly, the rheology of a product dictates much of the consumer experience, e.g. in relation to texture and mouthfeel. This book doesn’t overwhelm the reader with complex mathematical equations but takes a simple and practically-focused approach, interpreting the implications of rheological data for use in different food systems. Through this approach industry-based food developers / rheologists, students, and academics are given clear, concise interpretation of rheological data which directly relates to actual perceived functionality in the food. The functionality may relate to texture, structure and mouthfeel, and may result as a function of temperature, pH, flocculation, concentration effects, and mixing. The interpretative view is based on the principle that the food rheologist will produce a graph, for example of viscosity or gelation profiling, and then have to extract a practical meaning from it. For example, if viscosity falls with time as a function of pH, this knowledge can be used to tell the customer that the viscosity can be followed with just a pH meter and a stopwatch. Rheological measurements have shown that once the pH has dropped 1 unit after 10 minutes, the viscosity has been halved. This is the type of practical and valuable information for customers of the industrial food rheologist which the book will enable readers to access. Key features: A uniquely practical approach to the often difficult science of food rheology Includes chapters introducing the basics of food rheology before moving on to how data can be usefully and easily interpreted by the food scientist Can be used as a teaching aid on academic or industry-based courses

Release Date: 2016-01-31
Genre: Crafts & Hobbies

Weaving and Fabric in Antiquity: Materiality – Representation – Epistemology – Metapoetics presents 11 papers arranged under the four headings of the title which focus on the process of textile manufacture, the weaving process itself, and the materiality of fabric. Contributions address the problematic issues of cognitive archaeology, consumer research, literary theory and themes addressing both philosophical history and the history of reception of ideas and practice. The contributions seek both to close the critical gaps with respect to weaving, a broad and complex field in the area of ancient cultural techniques, and to identify new themes. Accordingly, the submissions expand our focus into late antiquity, to integrate texts such as letters written on Papyrus detailing the everyday correspondence of an Egyptian family or to spotlight the meaning of textile terms and the history of misunderstandings associated therein. Frequently overused analogies between writing and weaving are also examined in terms of their legitimacy as well as their limits. The papers presented here result from an international and interdisciplinary conference under the same title held in Castelen, near Basel in 2012. TEXT MOSTLY IN GERMAN

The Control and Standardisation of National Food Quality. There must be very many different opinions as to what this title means. To some people it will mean the control by legislation of additive and contaminant levels in food, to others it may mean the laying down of compositional standards for different food commodities, yet again some may consider that it covers the nutritional quality of the food and the maintenance of an adequate satisfactory diet for the population of the country. I think certainly that it could be all of these things and a glance at the variety of titles of papers which other speakers will be giving later in this symposium illustrates the very wide area which is covered by food quality in its many aspects. I will try only to present to you some of those aspects which are the concern of government in the control of food quality. I will not concern myself with those aspects which are the concern only of the manufacturer and his customer, and here I am thinking of flavour, appearance and physical state, such as whether canned, fresh or frozen. These aspects, which affect the type of products to be marketed, and also the aspects of quality control which set out to maintain the standard that the manufacturer has set himself, are I think outside my province.
