An especially exciting recent development is the finding that there
are important cholesterol-lowering agents, known as stanol esters, in
an oil fraction associated with the corn fiber produced by the quick
fiber process. These are the same ingredients that give the special
new spreads, e.g., benecol, their cholesterol-lowering capabilities.
Currently one of these ingredients in the special margarine products
comes from soy and the other from wood pulp. Both exist in corn fiber
oil in about equal proportions. The effects of these two appear to be
additive, so it is an advantage to have both ingredients in the same
product. These ingredients are worth about $10 per pound and each
bushel of corn has about 0.3 pounds. Thus these ingredients alone are
worth about $3 per bushel, even though they make up a small fraction
of each bushel of corn.
University of Illinois scientists pioneered important changes in the
ethanol fermentation process. Through the 1980s and 1990s, Professor
Munir Cheryan and colleagues developed and perfected continuous
membrane bioreactors (CMB) for ethanol production. This continuous
fermentation approach offers many advantages over batch processes.
Throughput is much faster, ethanol yields are higher, down time is
greatly reduced, purification and concentration are simplified,
equipment is much smaller for a given output, less floorspace is
required, capital costs are reduced, yeast costs are reduced, systems
are modular for greater flexibility, and by-product and waste
management are greatly simplified.
I know, off topic, but why do we grow corn, stead of 5 yr old, 50$
ton willow or poplar, willow can't keep up, only hemp or Konola has a
chance. Searching the archives, I found this guy with a post to a
continuous reactor, but, put the mixture through a three shake tube
from Alfa-laval, static in tube mixers from the dairy or ice cream
bis,can charge your customers for methanol many times over, eh?
Sorry, the problems with stateside biofuels is they think they can
create biofuels at 50 dollars a ton willow, we ain't haulin' it! you
haul it for that we got a problem with $20.00 ton corn silage, why
not make beef, eh, you really think you can double a farmers wages?
Nope, been dealin' with pennies per acre profits to long, its time to
create their own dynergy, but the problem lies, just as it lies in
the independant trucker, no one will ever agree about what kinda
bottled water is better, and the whole thing goes down the tubes with
no one wanting to be part of a team, we're left with ADM and even if
they didn't want it, they get the blame, cause there ain't any
teamwork, none.
I do think there was one post in the biofuels library with Cheryan
and a continuous proc, univ Illinois, in Ohio, some corn growin
country, some serious corn growin country, eh!
