Science of Ice CreamUdgave 1

Ice cream as we recognize it today has been in existence for at least 300 years, though its origins probably go much further back in time. Though no one knows who invented ice cream. The first ice cream making machine was invented by Nancy Johnson, of Philadelphia, in the 1840s. The Science of Ice Cream begins with an introductory chapter on the history of ice cream. Subsequent chapters outline the physical chemistry underlying its manufacture, describe the ingredients and industrial production of ice cream and ice cream products respectively, detail the wide range of different physical and sensory techniques used to measure and assess ice cream, describe its microstructure (i.e. ice crystals, air bubbles, fat droplets and sugar solution), and how this relates to the physical properties and ultimately the texture that you experience when you eat it. Finally, some suggestions are provided for experiments relating to ice cream and ways to make ice cream at home or in a school laboratory. The Science of Ice Cream is ideal for undergraduate food science students as well as for people working in the ice cream industry. It is also accessible to the general reader who has studied science to A level and provides teachers with ideas for using ice cream to illustrate scientific principles.
