On the other hand, cereal starches, such as wheat and corn starches were found to retain only water populations that are in fast exchange (on the deuterium NMR time scale) with bulk water. Therefore, one expects that potato starch granules would increase the stability properties and shelf-life of the foods in which they are utilized as an ingredient. These results suggest that fresh and freeze-dried powdered BHS have potential for utilization in food products as nutritive functional ingredients with increased stability and shelf-life.","The $\\sp1$H and $\\sp2$H NMR results showed that the major contributing factor to texture, waxiness and mealiness of potatoes is the solid potato matrix, especially the starch components and cell wall materials. Waxy potato cultivars and starches have higher ability to bind or trap more water than mealy potato cultivars. Potato starch is preferred over wheat or corn starch as a functional ingredient for improving and increasing the stability, rigidity and firmness of surimi gels, partly because potato starch has the ability to bind or trap water within its granule structure. The large number of NMR results obtained for a variety of starches and food formulations that include starches indicate the usefulness of NMR techniques for studying food formulations in relation to functionality and food process engineering.","Made available in DSpace on 2011-05-07T13:03:52Z (GMT).
