Utilization of withdrawn bread and corn meal mixtures for new feed production

Abstract

There is an evident problem with withdrawn bread in Serbia, in terms of quantity, environmental and health aspects. There is no organized way for withdrawn bread collecting and distributing for further processing. The absence of these actions contributes to the increasingly polluted environment, and creates problems in the food chain. This paper contributes to solving problem with withdrawn bread using extrusion of the mixtures of corn meal and withdrawn bread (50:50 and 60:40) moisturized up to 18% prior to extrusion. Extrusion of these mixtures was carried out in a single screw extruder (Metal-matic Beočin, Serbia) at temperature of 95-105°C. The results confirm that the obtained products are safe concerning microbiology and mycotoxicology. The total count of molds and microorganisms is below the maximum allowable concentration indicating that the produced extrudates could be used as safe feeds.
