<pre>Hello Dave Selway.

My name is Michael Bradley and I am working with a mill in California that
removes the stones prior to crushing. My company purchases most of the oil
while the mill which holds some very crucial patents collects the vegetable
water. It turns out that the vegetable water is useless, (actually less
than useless as a pollutant) as a food supplement if some waxes and toxins
contained in the stones and dissolved in the waste water are present.
However, as a source of antioxidants and polyphenols the water contains 100
times more of the "good stuff" than does the oil. I realize this sounds a
little outrageous but makes sense when one considers that polyphenols are
much more soluble in water than they are in oil. As for the organoleptic
properties of the oil I would have to say that oil produced in this manner
tends to be less bitter and seems to be "cleaner" and requires less settling
or filtering. The acidity levels are exceptionally low with one batch
consisting of 30 tons coming in at .09% ac. The majority of the oil
produced had ffa levels below .15%. The yield is slightly lower but this
may be a result of less wax from the stones. What is most interesting is
the possibility of having four valuable products to sell instead of one.
The stones are a very high source of calories, (I am told over 10 times that
of seasoned Oak). When separated prior to crushing and then dried in the sun
they resemble shelled peanuts The flesh, less the water, oil, and stones,
is light and sweet and should make a good food supplement for animals. The
environmental degradation caused by the indiscriminate dumping of waste
water in and around some mills in the Med is a real and chronic problem.

All in all, the process has lots of promise and potential. Imagine being
in the position of viewing the oil as a by product and water as the real
prize; of selling the flesh to feed farm animals and using the stones to run
your plant. It is certainly too early to make any solid predictions about
the spread and viability of this technique but it certainly is worth
investigating.
