Protein content and total proteolytic activity of honey samples of different floral origins.

aProtein content was determined by the method of Bradford.bTotal proteolytic activity is expressed in mU mg prot−1, where mU corresponds to the amount of enzyme yielding 0.001 units of absorbance at 280 nm per min (pH 7.5, T = 30°C),Proteolytic activity was assessed on gelatine in solution (mean ± SD, n = 6).c,d,e,f,g,hThe mean values with different letters superscript (in the same column) are significantly different (p*The lower script code indicates the geographical origin of the honeys: MT (Province of Matera) and PZ (Province of Potenza).
