Present study reports the effect of temperature, type of wall material and its ratio to the juice dry matter on the retention of phenolic acids, anthocyanins and fiavonol glycosides in sour cherry Marasca juice encapsulated by spray drying. Individual polyphenols were determined and quantified by HPLC and response surface methodology approach was employed in order to observe the differences between different classes of sour cherry polyphenols regarding the conditions applied for encapsulation process. Maltodextrin 13-17 DE used in ratio 3:1 showed to be the optimal wall material for encapsulation of sour cherry juice at temperature of 200 degrees C, with the highest retention of phenolic acids and anthocyanins, namely 93.31 and 88.68%, respectively. Adversely, fiavonol glycosides were retained to the most (84.01%) in juice encapsulated at 180 degrees C with gum arabic added in ratio 2:1. (C) 2017 Elsevier Ltd. All rights reserved.
