In terms of the effect of drying temperature, a similar pattern to the TCC loss as a result of incrasing the inlet temperatures was also observed in relation to EE. It is indicated that increasing temperature resulted in reduction of EE the explanation for this phenomenon is that the degradation of criterions at higher temperature, as discussed above, lead to reduct EE. Further, according to *******,the balance btween the rate of water evaporation and film-formation may break due to high inlet temperature;therefore, wall system of microcapsules is broken down. This phenomenon Will cause A low EE. Similar findings were also reported By authors (***********).However, ******(*)states that effect of inlet and outlet temperature On EE was not important at low feed solid levels. The higher EE was not obtained when combination of these temperature was carried out.Overall, *4 shows that it was not required to go past 20% maltodextrin for higher EE.
In this study,the TCC was significantly decreased when mltodextrin 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 know that carotenoid content in powder is effectively protected at s high initial feed solid. Similar observation Were found
