Abstract:
Natural gums are natural polymers, which mainly consists of carbohydrates sometimes with small amounts of proteins and minerals. They are made from different parts of plants seaweeds or bacteriological activity. The gums are used very much in the food industry as thickeners and they are changing the viscosity significantly already in low concentration. The natural products are normally purified from water solutions, in which they are sometimes treated for change in molecular size for obtaining other final properties. As one step in the purification filtration, membrane filtration or centrifugation can be used. After the purification the solutions are sometimes concentrated by evaporation or solidified by cooling, drum drying or spray drying.
