  • Microwave-assisted preparation of potato starch silicated with silicic acid

    Publikacja

    - CARBOHYDRATE POLYMERS - Rok 2010

    Application of microwave irradiation for the silication of granular potato starch with silicic acid, and the properties of silicated starch were investigated. Potato starch was esterified on 20 min microwave irradiation of starch with silicic acid, applying the power of 450 or 800Wand, for comparison, on 120 min convectional heating of the reagent blend at 100 ◦C. The degree of esterification and the reaction efficiency did not...

  • Kinetics and mechanism of the chemically modified starches during gelatinization.

    Publikacja

    - Rok 2013

    Native starch was silicated by means of microwave-assisted reactions with varying doses of reagents. Resulting products were characterized by DSC and HMR-relaxation methods. It was observed that the hydratation of the silicated starches during gelatinization decreases when compared to that of the native potato starch. The amount of unfrozen water for ungelitinizated silicated starches are less than in control samples. At the same...

  • Rheology of potato starch chemically modified with microwave-assisted reactions

    Publikacja

    - LWT-FOOD SCIENCE AND TECHNOLOGY - Rok 2013

    Native potato starch was sulfated, selenated, borated, silicated and zincatated by means of microwave-assisted reactions with varying doses of relevant reagents. Resulting products were characterized involving rheological behavior of pastes, their weight-average molecular weight (Mw), and radius of gyration (Rg). Most of the pastes showed shear-thinning behavior, with the flow behavior index (n) below unity. The pastes of starch...
