Food and dairy powders are created by dehydrating perishable produce, such as milk, eggs, fruit and meat, in order to extend their shelf life and stabilise them for storage or transport. These powders are in high demand for use as ingredients and as food products in their own right, and are of great economic importance to the food and dairy industry worldwide. Today, the ability to control food and dairy powder quality is a source of key competitive advantage. By varying the dehydration process design, and by controlling the technological and thermodynamic parameters during dehydration, it is possible for manufacturers to engineer the biochemical, microbiological and physical characteristics of the food powder to meet their specific product requirements. This book provides an overview of the existing, adapted or new techniques used to analyse safety and quality in modern food and dairy powders. Based on original research by the authors, the book uses 25 commercial dairy and non-dairy powders to illustrate a range of biochemical and physical methods used to evaluate and characterise powdered food products. Written from a practical perspective, each chapter focuses on a particular analytical technique, outlining the purpose, definition and principle of that method. The authors guide the reader through all of the instruments needed, the safety measures required, and the correct procedures to follow to ensure successful analysis. Instructions on accurate measurement and expression of results are included, and each chapter is richly illustrated with original data and worked examples. Analytical Methods for Food and Dairy Powders is a unique step-by-step handbook, which will be required reading for anyone involved in the development and manufacture of powdered food products. Food and dairy scientists based in industry will find it essential for new product development and improved quality control, while researchers in the laboratory will especially value the new techniques it comprises.

This third volume in the Handbook of Food Science and Technology Set explains the processing of raw materials into traditional food (bread, wine, cheese, etc.). The agri-food industry has evolved in order to meet new market expectations of its products; with the use of separation and assembly technologies, food technologists and engineers now increasingly understand and control the preparation of a large diversity of ingredients using additional properties to move from the raw materials into new food products. Taking into account the fundamental basis and technological specificities of the main food sectors, throughout the three parts of this book, the authors investigate the biological and biochemical conversions and physicochemical treatment of food from animal sources, plant sources and food ingredients.
This book serves as a general introduction to food science and technology, based on the academic courses presented by the authors as well as their personal research experiences. The authors' main focus is on the biological and physical-chemical stabilization of food, and the quality assessment control methods and normative aspects of the subsequent processes. Presented across three parts, the authors offer a detailed account of the scientific basis and technological knowledge needed to understand agro-food transformation. From biological analyses and process engineering, through to the development of food products and biochemical and microbiological changes, the different parts cover all aspects of the control of food quality.

This book is a source of basic and advanced knowledge in food science for students or professionals in the food science sector, but it is also accessible for people interested in the different aspects concerning raw material stabilisation and transformation in food products. It is an updated and translated version of the book "Science des aliments" published in 2006 by Lavoisier. "Science des aliments" is a general and introductory food science and technology handbook, based on the authors' Masters and PhD courses and research experiences. The book is concise, pedagogical and informative and contains numerous illustrations (approximately 500 original figures and tables). In three volumes), it summarizes the main knowledge required for working in food industries as scientists, technical managers or qualified operators. It will also be helpful for the formation of students in food science and biotechnologies (bachelor's and master's degree).
Les principes de l'analyse dimensionnelle, associée à la théorie de similitude et à des essais sur maquette, ont été établis au cours des quatre derniers siècles par de grands noms de la science, depuis les travaux de Galilée et de Newton jusqu'aux études emblématiques de Froude (carènes de bateaux) et de Reynolds (écoulements de liquides). Paradoxalement, force est de constater qu'ils ne sont aujourd'hui que rarement présentés dans nos formations en génie des procédés comme un outil générique et d'avenir, et de fait très peu mis en pratique.
L'objectif de cet ouvrage est de démontrer que l'analyse dimensionnelle demeure une voie fiable, robuste et pertinente pour comprendre, dimensionner, modéliser et conduire les procédés complexes de transformation de la matière en réacteur en dégageant une vision synthétique et physique des interactions produit/procédé. En mobilisant les acquis des recherches récentes dans le domaine, ce livre revient en détail sur le cadre théorique qui permet de respecter les principes de la théorie de similitude dans le cas de procédés mettant en oeuvre un matériau dont une propriété physique est constante, puis, et c'est l'une de ses principales originalités, non constante ; il indique enfin les règles à suivre pour construire rigoureusement une relation de procédé (corrélation semi empirique) entre nombres sans dimension et mobiliser cette connaissance pour raisonner l'extrapolation. Des cas résolus et des exemples originaux issus essentiellement des travaux de recherche des auteurs en génie des procédés permettent d'illustrer les approches conceptuelles et de renforcer la pédagogie de l'ensemble.
Pratique et synthétique, cet ouvrage s'adresse aux élèves ingénieurs en génie des procédés, de niveau bac + 2 au master, et bien sûr, aux ingénieurs, doctorants et scientifiques confirmés, soucieux de tirer le meilleur profit de leurs expérimentations sur des équipements de laboratoire et pilotes.
