    Nyckelord :cellulose; microsphere; biopolymer; encapsulation; dispersing agent;

    Sammanfattning : Microspheres are spherically shaped particles within the size range of 1-1000 μm in diameter. Due to the their small size and round shape, microspheres show many advantages in various applications such as pharmaceuticals, composites and coatings. LÄS MER

  7. 5. Acid hydrolysation of starch and formulation of starch microspheres

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Zahrai Najeeb; [2015]
    Nyckelord :Starch acid hydrolyze; starch microspheres; Rheology; läkemedelsteknologi; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : The aim of this diploma work is to investigate the acid hydrolyses of two types of starch, waxy barley and maize starch to be applied for further usage, in rheology studies and formulation of starch microspheres. Modified starch has always been essential in many areas, especially in tablets, where it could be used as a disintegrant. LÄS MER
