Stickiness and agglomeration of blackberry and raspberry spray dried juices using agave fructans and maltodextrin as carrier agents

摘要

The?present study shows the?effect of agave fructans as?a?carrier agent compared with maltodextrin to?evaluate the?particle stability of blackberry and raspberry juices. A?pilot spray dryer was used with feed flow of?20?mL?h–1 and atomization rate of 28?000?rpm. The?inlet air temperature of 180?°C and outlet air temperature of 80?°C were used as?parameter constants. Only?the?parameters of the?carrier agent concentration of 5,?7.5?to 10%?(w/v) were changed. The?concentration of 10% agave fructans was high enough to recover the?higher yields of 89% only for blackberry, for?raspberry the?concentration of?7.5% agave fructans was sufficient to?recover the?yield of?67%. The?stability diagrams show the?conditions of the?particles that should not be exceeded when leaving spray drying, as?well as the?storage conditions that must be followed to avoid agglomeration.
