Sažetak

In this paper, microbial quality of cocoa husk, a by-product of chocolate production after roasting cocoa bean, was evaluated. Cocoa husk was treated by high-voltage electrical discharge (HVED) at 40 and 80 Hz during 15, 30 and 45 min in water suspension (at concentration of 1,5 and 3,0%). The research showed that cocoa husk, although it has been subjected to thermal treatment during roasting, is heavily loaded with microorganisms, but the number of enterobacteria may be reduced by HVED. Subsequent drying at 40 °C, on the contrary, enables revival of microorganisms.
