Noni fruit from Tahitian Noni International is made from puree of
the whole fruit. A competitor product Natural Styles are dried fruit
as it says on the page Noni Quality Assurance:
http://store.yahoo.com/islandtrend/noname1.html
"mashed fruits are deseeded and immediately dried by our proprietary
process".
What happens to many of the active ingreedients when a fruit is
dried, is hard to say. Has not yet been measured. According to
http://www.incc.org/before_buy.htm about The Powdered Juice Method
:
"The drying or dehydrating process removes some nutritional value
from the fruit. In addition, it is difficult to determine how much
noni you are getting in each serving."

Wouldn't it seem clear what would be the best juice ?
