Drying experiment
Frozen mango puree was thawed overnight at room temperature
(23 C), and afterward blended for 5 min to a uniform consistency
using a bench top blender (Oster Osterizer, Mexico) with
lowest speed setting. The puree was dried to below 0.05 kg
water/kg dry solids by Refractance Window drying, freeze drying,
drum drying, or spray drying. Due to difficulty in spray drying of
this sugar-rich material, maltodextrin (DE = 10) (Grains Processing
Corporation, Muscatine, IA) was added to mango puree before
spray drying. No addition of carrier was used for the other three
drying systems. Detailed procedures for each drying method are
described below:
