Green cookies due to terpenoid presence
Compounds may help cotton resist disease
By KURT ABRAHAM
Battalion Reporter
Joe Six-pack wanted to show
friends that his cooking ability ex
tended beyond thawing frozen TV
dinners, so he baked a batch of
chocolate-chip cookies —- only to
have them turn a strange green
color in the process.
Despite his experience with the
cookies, Joe is not necessarily a fail
ure as a cook. According to Dr. John
Halloin, it’s possible that even the
best of bakers will run into an occa
sional batch of green cookies. He
said it all has to do with two chemi
cal compounds that find their way
into flour, and into cotton seed.
Halloin conducts research for the
U.S. Department of Agriculture’s
Cotton Pathology Laboratory, lo
cated on the west campus of Texas
A&M University. One of his latest
studies involved the compounds
known as terpenoid aldehydes and
tannins.
“When present in cotton seed,
the two compounds may be helpful
in stopping the growth of fungi,”
said Halloin. “But when they find
their way into baking ingredients,
such as flour, the end-product will
have greenish tintf to it, as in the
green cookies.”
Terpenoid aldehydes, better
known to plant physiologists as gos-
sypol, and tannin are considered
antimicrobial compounds, Halloin
said. This means they are capable of
either killing microbes or keeping
them from growing. Microbes are
minute organisms most often as
sociated with various bacteria forms,
including fungi.
“Because of the nature of these
compounds, we were looking for a
link between their presence in cot
ton seed and the resistance of the
seed to disease such as fungi,” Hal
loin said. “But the results are not
totally conclusive, because gossypol
is not always present.”
Gossypol is only found in the
glandless type of cotton seed if there
has been genetic contamination,
said Halloin. Genetic contamination
involves the altering of the basic
chemical chains that form the com
pound. However, gossypol is almost
always found in glandular cotton,
added Halloin.
Stanford to spend $40 million
on atomic structure research lab
More than $40 million will be in
vested during the next two years to
construct research facilities to serve
a field so new only a handful of sci
entists now realize its potential, says
a California chemist.

chrotron radiation, a physical
chemistry process that allows scien
tists to take the atomic structure
apart and study electron correla
tions by using electron spectros
copy.
A feature of synchrotron radiation
is the holding of charged electrons
in large circular structures called
electronic storage rings.
Construction bids up to $40 mil-
ion have been let to beef up existing
storage ring facilities at Stanford
University and to construct new
ones in Wisconsin and at the trou
bled Brookhaven, N.Y. site.
Shirley, former chairman of
chemistry at the University of
California at Berkely, now is as
sociate director and head of the ma
terials and molecular research divi
sion of the Lawrence Berkely Labo
ratory there.
Shirley said it had several distinct
advantages over more conventional
electron diffraction methods, in
cluding the fact it is nondestructive
and is atom specific.
The Robert A. Welch Foundation
of Houston, which is helping fund
Shirley’s project and which spon
sored Monday’s lecture, is among
the 25 largest research foundations
in the world, funding over $90 mil
lion worth of projects which have
resulted in 8,000 published articles.
