"Ice Cream," 7th Edition focuses on the science and technology of frozen dessert production and quality. It explores the entire scope of the ice cream and frozen dessert industry, from the chemical, physical, engineering and biological principles of the production process to the distribution of the finished product. It is intended for industry personnel from large to small scale processors and suppliers to the industry and for teachers and students in dairy or food science or related disciplines. While it is technical in scope, it also covers much practical knowledge useful to anyone with an interest in frozen dessert production. World-wide production and consumption data, global regulations and, as appropriate, both SI and US units are provided, so as to ensure its relevance to the global frozen dessert industry.

This edition has been completely revised from the previous edition, updating technical information on ingredients and equipment and providing the latest research results. Two new chapters on ice cream structure and shelf-life have been added, and much material has been rearranged to improve its presentation. Outstanding in its breadth, depth and coherence, "Ice Cream," 7th Edition continues its long tradition as the definitive and authoritative resource for ice cream and frozen dessert producers.

This book examines both the primary ingredients and the processing technology for making candies. In the first section, the chemistry, structure, and physical properties of the primary ingredients are described, as are the characteristics of commercial ingredients. The second section explores the processing steps for each of the major sugar confectionery groups, while the third section covers chocolate and coatings. The manner in which ingredients function together to provide the desired texture and sensory properties of the product is analyzed, and chemical reactions and physical changes that occur during processing are examined. Trouble shooting and common problems are also discussed in each section. Designed as a complete reference and guide, Confectionery Science and Technology provides personnel in industry with solutions to the problems concerning the manufacture of high-quality confectionery products.

The approach to teaching the concepts of food processing to the undergrad uate food science major has evolved over the past 40 years. In most under graduate food science curricula, food processing has been taught on a commodity basis. In many programs, several courses dealt with processing with emphasis on a different commodity, such as fruits and vegetables, dairy products, meat products, and eggs. In most situations, the emphasis was on the unique characteristics of the commodity and very little empha sis on the common elements associated with processing of the different commodities. Quite often the undergraduate student was allowed to select one or two courses from those offered in order to satisfy the minimum standards suggested by the Institute of Food Technologists. The current 1FT minimum standards suggest that the undergradu ate food science major be required to complete at least one food processing course. The description of this course is as follows: One course with lecture and laboratory which covers general characteristics of raw food materials, principles offood preserva tion, processing factors that influence quality, packaging, water and waste management, and sanitation. Prerequisites: general chemistry, physics, and general microbiology."

In the food industry, controlling crystallization is a key factor in quality as it relates to texture, with some foods requiring the promotion of crystallization and others its prevention. In the first publication to focus specifically on this process as it applies to food, Crystallization in Foods covers fundamental principles in ice, sugar, and lipid crystallization, and their applications. Drawing on examples throughout of the practical use and impact of crystallization on food structure, texture, and quality; and enhanced with numerous equations and illustrations, Crystallization in Foods is a valuable resource for food engineers and other scientists working with crystallization in foods, particularly in the dairy, confectionery, frozen foods, and baked goods industries. In addition, this book may be of interest to scientists and other professionals in the personal care and cosmetics industry, which shares some of the same quality and texture concerns as the food industry.

Emulsifiers, also known as surfactants, are often added to processed foods to improve stability, texture, or shelf life. These additives are regulated by national agencies, such as the FDA, or multi-national authorities, such as the EEC or WHO. The amphiphilic molecules function by assisting the dispersion of mutually insoluble phases and stabilizing the resulting colloids, emulsions, and foams. Emulsifiers can interact with other food components such as carbohydrates, proteins, water, and ions to produce complexes and mesophases. These interactions may enhance or disrupt structures and affect functional properties of finished foods. In dairy processing, small molecule emulsifiers may displace dairy proteins from oil/water and air/water interfaces, which affects stability and properties of the foams and emulsions. In baked products, emulsifiers contribute to secondary functionalities, such as dough strengthening and anti-staling. Synthetic food emulsifiers suffer from the stigma of chemical names on a product's ingredient statement. Modern consumers are seeking products that are "all natural." Fortunately, there are a number of natural ingredients that are surface-active, such as lecithin, milk proteins, and some protein-containing hydrocolloids. Mayonnaise, for example, is stabilized by egg yolk. This book can serve as both a guide for professionals in the food industry to provide an understanding of emulsifier functionality, and a stimulus for further innovation. Students of food science will find this to be a valuable resource.

Bei dem Vorhaben, eine Einfiihrung in die Stromrichterschaltungen zu schreiben, erhebt sich als erstes die Frage, ob man bei der Abhandlung des Stoffes den Schwerpunkt auf die Didaktik, also auf eine moglichst verstandliche Darstellung, oder aber auf den praktischen Nutzen, also auf die Bedeutung fUr die Anwendungen legen solI. Fiir die Auswahl des Stoffes und fiir die Art der Darstellung gelten in beiden Fallen unt- schiedliche Gesichtspunkte. . Die Erfahrungen einer achtzehnjahrigen Lehrtatigkeit an der Tech- nischen Universitat Miinchen iiber das Thema Stromrichtertechnik haben gezeigt, daB der Umgang mit stiickweise stetigen Vorgangen in auf- einanderfolgenden Zeitintervallen - also der Umgang mit den fiir die Stromrichterschaltungen typischen Erscheinungen - bei der Einarbei- tung in den Stoff wesentlich groBere Schwierigkeiten bereitet, als die nachtragliche "Obertragung der Ergebnisse auf die praktischen Anwen- dungen. Daraus wurde der SchluB gezogen, daB offensichtlich ein Bediirfnis nach einer Einfiihrung in die Stromrichterschaltungen besteht, bei der den didaktischen Gesichtspunkten der Vorrang gegeben wird; vielleicht wird durch ein solches Buch sogar eine Liicke im deutsch- sprachigen Schrifttum geschlossen.

Cosa mangia l America nell era moderna? Probabilmente molte delle cose che mangeremo anche noi nel prossimo futuro.

Ormai la dinamica dei flussi e chiara: l hamburger e la Coca Cola sono solo i simboli di un modello di consumo che, con diverse sfaccettature, ha definitivamente contaminato la nostra cultura del cibo. Se per noi gli spaghetti sono intoccabili e la pizza continua a essere il piu gettonato tra i fast food, e comunque vero che le giovani generazioni sentono irresistibile il richiamo del cibo made in USA. All insegna dell intercultura e del mercato globale, ci troveremo sempre di piu a fare i conti con prodotti per noi alieni come i Marshmallow (le famose caramelle spugnose a forma di cilindretto), magari in versioni addomesticate per sposarsi meglio con il gusto mediterraneo. Del resto il Parmigiano Reggiano e lo Speck dell Alto Adige negli hamburger di McDonald s sono gia una realta ed e un dato di fatto che i banchi del supermercato si arricchiscano ogni giorno di nuove proposte sempre piu tecnologiche. Le "patatine" che hanno l aspetto e il sapore del bacon (senza averlo mai visto nemmeno da lontano) sono dei must dell happy hour, cosi come prosegue il successo degli energy drink dal gusto dubbio e delle gomme americane (per l appunto ) che frizzano.

E giusto? E salutare? Chissa Di sicuro c e una cosa: e la realta dei nostri giorni. E allora, perche non provare a conoscerla meglio? Perche non lasciare da parte diffidenze e pregiudizi per dare spazio alla pura e semplice curiosita?

Pagina dopo pagina, questo libro ci introduce in un mondo diverso ma certamente affascinante, dove si scopre che il cibo puo avere dimensioni e significati differenti da quelli che gli attribuiamo abitualmente. Oltre il piacere, oltre il nutrimento, diventa gioco, ricerca tecnologica, sfida scientifica, desiderio di stupire e di distinguersi Gli autori, esperti riconosciuti del settore, si approcciano a questo mondo con piacevole ironia e distacco professionale, guidandoci alla scoperta dei Pixy Stix, piuttosto che dei Circus Peanuts e dei Lucky Charm, senza peraltro trascurare argomenti piu vicini al nostro quotidiano, dalla preparazione del gelato alla conservazione sotto vuoto, alle indispensabili attenzioni igieniche da seguire in cucina.

Leggendo, si ha conferma di come l'alimentazione sia davvero una scienza complessa e di quanto siano ampi e stimolanti gli orizzonti che apre alla ricerca, ma si ha anche la percezione netta di quanta distanza possa esserci tra le diverse culture alimentari.

Il mondo e bello perche e vario. E vero: la diversita e una ricchezza. Ma perche lo sia veramente va approcciata con curiosita e desiderio di confronto, gli stessi atteggiamenti che scaturiscono in modo irresistibile dalla lettura di questo libro.

"Se avete un interesse per l alimentazione, sara un appetitosa lettura" - Linda Brazill Capital Times

"Queste pagine contengono moltissime informazioni sulla sicurezza alimentare, sul fenomeno del freezer burn (bruciatura da freddo) e sulle allergie. Ma cio che rende il libro cosi appassionante e piacevole sono le storie legate ai nostri sfizi alimentari. Gli Hartel trattano questioni riguardanti le caramelle a forma di arachidi (Circus Peanuts), i marshmallow, la data di scadenza delle merendine, spiegano se preferire le scagliette alle codette di cioccolato, la torta fatta in casa dalla mamma ai preparati della Cameo. Ma la storia piu gustosa che gli Hartel ci raccontano e come si fanno le ciliege ripiene ricoperte al cioccolato" - Linda Brazill, Capital Times
