Abstract

Netopljivi β-glukan izoliran je iz otpadnog pivskog kvasca primjenom triju različitih postupaka izolacije i osušen primjenom triju različitih metoda sušenja. Analizirani su kemijski sastav, veličina čestica, biološka aktivnost i druge karakteristike važne za primjenu izoliranih proizvoda. Kombinacijom ultrazvučne obrade i sušenja raspršivanjem uzoraka β-glukana dobivene su mikročestice, čije su dimenzije bile optimalne za biološku aktivnost.

Abstract (english)

Water insoluble β-glucan was isolated from spent brewer's yeast using three different isolation procedures. Afterwards, it was dried using three different drying methods. Chemical composition, particle dimensions, biological activity and other characteristics important for the application of isolated products were analysed. Microparticles, which size was optimal for the biological activity, were obtained by combined usage of ultrasound and spray drying tehniques.
