I often freeze soft berries like strawberries, raspberries, cherries, and blueberries for use later in the season with my Mehu-Liisa Steam Juicer. A couple quarts of frozen berries on top of a batch of apples, pears, peaches, or white grapes yields a wonderful mixed fruit juice. I have noticed what seems to be increased juice production when I do this. It has been my opinion that freezing fruit breaks down the fiber of the fruit and thus yields more juice. This article abstract from the International Journal of Fruit Science seems to corroborate this idea.
I will be doing some comparison juicing tests this season to see if this is indeed true. I’ll keep you up to date!
As always, I am interested in your experiences with steam juicing with the Mehu-Liisa Steam Juicer.
