A method is described for processing fruit or vegetables, e.g.,
cranberries, into two different juices. One of the two juices has a
relatively high level of phytochemicals and a relatively low level of
sugars and acids. The other of the two juices has a relatively low level
of phytochemicals and a relatively high level of sugars and acids. The
method of the invention entails providing three juice streams. The first
juice stream is passed through an ultrafiltration apparatus or some other
apparatus that is capable of preferentially separating the relatively
lower molecular weight compounds, e.g., sugars and acids, from the
relatively higher molecular weight compounds, e.g., phytochemicals. This
process creates two juice fractions: a juice fraction that is relatively
enriched in sugars and acids and a juice fraction that is relatively
enriched in phytochemicals. The second juice stream is combined with the
juice fraction that is relatively enriched in sugars and acids to create
a juice that has a relatively high level of sugars and acids and a
relatively low level of phytochemicals. The third juice stream is
combined with the juice fraction that is relatively enriched in
phytochemicals to create a juice that has a relatively high level of
phytochemicals and a relatively low level of sugars and acids.
