stated that effect of inlet and outlet tem- perature on EE was not important at low feed solid levels. The higher EE was obtained when combination of these temperatures was carried out. Overall, Fig. 4 shows that it was not required to go past 20% maltodextrin for higher EE.
In this study, the TCC was significantly decreased when malto- dextrin concentration was increased from 10% to 30%. This is due to high maltodextrin concentration leading to lower TCC obtained as the feed juice was constant. On the other hand, an increase in EE was observed as increasing maltodextrin concentration. This is well known that carotenoid content in powder is effectively pro- tected at a high initial feed solid. Similar observations were found inotherstudies(WagnerandWarthesen,1995;Rodri ́guez-Huezo et al., 2004).
