      Abstract:

      The goal of this work was to determine the anthocyanin retention   and physicochemical properties of haskap powder prepared by   Refractance WindowTM (RW) drying. In general, the RW-dried powder   particles had a smooth surface with similar thickness, consistent   with the preparation method, and had a solubility of 75.63% in   water. The RW-dried powder (consisting of 98% haskap berries)   retained approximately 93.8% of anthocyanins from the original   frozen fruits, as assessed by the pH-differential method. This   result is in good agreement with HPLC analysis that indicated   92.9% retention. Three anthocyanins were identified in frozen   berries and RW-dried powder: cyanidin 3-glucoside, cyanidin   3-rutinoside, and peonidin 3-glucoside. Surprisingly, cyanidin   3-rutinoside exhibited the lowest retention.
