Aseptic Processing and Packaging of Particulate Foods

Publications in food technology proliferate; however, noticeable by its absence of coverage is the subject of processing and packaging of particulates in foods. Recent years have seen significant advances which will almost certainly result in substitution of existing and conventional retorting. In addition, when com bined with high temperature/short time (HTST) processing, we can expect substantial further growth, reflecting quality and convenience advantages over products processed from yesterday's technologies. The anticipated growth in particulates is driven by both materials and packaging advances and only requires modest marketing of the organoleptic advantages to establish their place on menu options. The directions taken in packaging developments, especially those interfacing with the latest and established methods of processing, are increasingly influ enced by the need to design packaging on a cradle-to-grave basis. Time was when multi-laminated films on board satisfied the total needs of consumers of aseptic products. The problems of recycling combustible, i.e. energy generating mate rials laminated with aluminium foil, are becoming sensitive issues in a world preoccupied with recycling, and are creating openings for alternative and envi ronmentally friendly material combinations. This book brings together advanced technologies in the field, to provide information for professionals with interests in aseptic processing on how to go about selecting a system appropriate to their commercial needs and constraints.

Klappentext
