Stabilisers, thickeners and gelling agents are extracted from avariety of natural raw materials and incorporated into foods togive the structure, flow, stability and eating qualities desired byconsumers. These additives include traditional materials such asstarch, a thickener obtained from many land plants; gelatine, ananimal by-product giving characteristic melt-in-the-mouth gels; andcellulose, the most abundant structuring polymer in land plants.Seed gums and other materials derived from sea plants extend therange of polymers. Recently-approved additives include themicrobial polysaccharides of xanthan, gellan and pullulan.
This book is a highly practical guide to the use of polymers infood technology to stabilise, thicken and gel foods, resulting inconsistent, high quality products. The information is designed tobe easy to read and assimilate. New students will find chapterspresented in a standard format, enabling key points to be locatedquickly. Those with more experience will be able to compare andcontrast different materials and gain a greater understanding ofthe interactions that take place during food production. Thisconcise, modern review of hydrocolloid developments will be avaluable teaching resource and reference text for all academic andpractical workers involved in hydrocolloids in particular, and fooddevelopment and production in general.
