    Composition and Physico-Chemical properties of lyophilizet royal jelly
    (Uludağ Üniversitesi, 2011) Balkanska, Ralitsa; Kashamov, Borislav
    The aim of the research was to study some of the components and physico-chemical properties of lyophilized royal jelly (LRJ). Six royal jelly samples produced in Bulgaria were lyophilized. The samples were preserved at -18 0C before analysis. Water content, proteins, lipids, sugars, ash, pH, total acidity and electrical conductivity were analyzed. It was found that LRJ contains: water (3,49–4,76%), lipids (3,09–8,56 %), fructose, glucose and sucrose (24,27–32,67 %), ash (2,50–3,03 %), pH (3,8–4,0), total acidity (10,67–12,88 ml 0,1 N NaOH/g). The values of LRJ electrical conductivity of 1 % water solution was in the range 421–481 µS/cm.
