Razvoj metode za izdelavo granul sončničnega lecitina z vlažnim iztiskanjem = Development of a method for sunflower lecithin granules production with wet extrusion : industrijska farmacija
Zaletel, Nina
Lecitin se široko uporablja kot emulgator in solubilizator v živilski, krmni, farmacevtski in kozmetični industriji, ima pa tudi še številne druge industrijske uporabe. Znano je tudi, da ima koristne ...lastnosti kot prehranski dodatek, saj naj bi v krvi zniževal nivo holesterola. V okviru magistrske naloge smo izdelali granule sončničnega lecitina z metodo vlažnega iztiskanja. Cilj je bil izdelati granule s čim višjim deležem lecitina, dobro pretočnostjo in ustrezno porazdelitvijo velikosti delcev. Kot vstopni material smo uporabili sončnični lecitin Lipoid H 20 in različne pomožne snovi ter različne postopke izdelave granul. Eksperimente granuliranja smo izvedli z visokostrižno granulacijo (>>High Shear Granulation<<, oscilirajočo granulacijo in metodo vlažnega iztiskanja (>>Wet Extrusion<<), v kombinaciji z oscilacijskim granuliranjem ali mletjem. Zadnja uporabljana tehnologija se je pokazala kot najboljša, ker je zagotovila visok delež lecitina v granulah, primerno velikost in porazdelitev granul in primerne reološke karakteristike granul.
