The moisture contents and other parameters of
powder produced by a COJ/MD ratio of 60:40 were not evaluated
because of the stickiness, low glass transition temperature of this
powder. The moisture content and water activity (aw) of powder
decreased with increasing maltodextrin concentration likely
because the sugar and acid in juice-rich powder is highly hygroscopic
and maltodextrin increases the total solid of the feed and
reduces the amount of water evaporation
