I have an idea to make a berry juice concentrate that contains the
skins and seeds of the berry. The reason I want to do this is because
there are a lot of vitamins and antioxidents in the skin and seeds of
the berries and I'd like to drink these too.

I plan on using a blender to turn the berries into a puree (juice skin
and seeds) and then add sugar and pasteurise the juice so that it
lasts for 6 months after I bottle it.

Has anyone ever done this? I guess one problem might be the fibres of
the skin and seeds floating or sinking so that it doesn't look so
good. I thought one way around this is to use a commercial pectin to
hold the fibres in solution.

Any ideas? Perhaps the skins will be mold forming - even though they
will be cleaned thorougly? But if I pasteurise should be o.k right?
Best wishes,
Andrew
