Status of IFAS and CREC Budget
Summary of Budget Matters
by Harold Browning, Center Director
The following is a brief overview of our
budget situation following the special ses-
sion of the legislature that convened in
December. The Special Session called for a
return of state general revenue funds from
the current fiscal year which started in July,
200 1. State agencies were asked for a "cash
callback" to make up for lost revenue from
the declining Florida economy in recent
months. The share of that callback in IFAS
was over $8 million, but some assistance
was provided in meeting the callback
through the legislature approving non-re-
curring funds to replace a portion of the
state funds recalled. Thus, the actual cut
w as about $4.6 million. Administrative re-
ductions, off-the-top savings, and savings
from personnel vacancies were used to re-
duce the impact of the cuts, and ultimately,
individual units were informed of cuts that
they would experience.
By the end December, CREC had returned
$137,000 of state funds to meet our required
reductions. This came from vacant USPS
and A&P positions salary savings. Lim-
ited spending of all state funding at CREC
during the period provided some additional
flexibility Discussions with CR .C faculty
and infrastructure departments led to a plan
to continue providing support to the Cen-
ter under the budget reductions. Details of
the budget for the remainder of the year
include the following:
A freeze is in effect for all USPS and
A&P positions. Those that have been
vacated since the freeze was
implemented will not be filled. but some
substitution of use of OPS to meet
needs of critical positions is being
made. This freeze is likely to continue
past July of2002

Dr. Moore Retires
by Dr John Attaway
S-, After 59+ years of service to the Florida citrus grower, Dr.
Edwin L Moore has retired from the Scientific Research
Department of the Florida Department of Citrus, effect i e
December 31, 2001. This is literally the end of an era.
After receiving his Ph D in food chemistry from the Univer-
sity of Massachusetts, Dr. Moore joined the staff of the Florida
Citrus Commission on July 1, 1942. His initial research project
was to find a way to ship orange juice to American service men serving overseas during
the Second World War. The result of the project was the development of frozen concen-
trated orange juice technology which was patented in 1948 by Dr. L.G. MacDowell, Dr.
E.L. Moore and Mr. C.D. Atkins,
In the subsequent years from the 1940s to the 2000s, Dr. Moore contributed -o even
research project by the FCCDOC staff in the area of citrus juice processing.
Dr. Moore continues to maintain his office in the Packinghouse and w'r I
continue to provide his expertise to CREC and the citrus industry.

Budget update... from page 1
With some minor adjustments to the operating budgets for the
remainder of the year, we will continue to support the pro-
grams of the center. The resources of the Center have been
allocated to complete the current year with some contingen-
cies for unexpected facilities repairs, utilities and other needs.
A carry-over contingency also has been set aside to allow
some flexibility as we move into the next fiscal year.
Faculty at CREC have discussed some measures that will
conserve the resources of the Center and several of these
have been implemented, including additional charge backs
on some of the support services at the Center.
The prospects for state budget improvement for the next year
starting in July are uncertain as the Legislature begins to address
state shortfalls, but at this time, the budget cuts experienced
during 2001 may establish the starting point for next year's
budget. We continue to make plans that will help address the
future budget situation. Planning also is advancing in IFAS to
address the budget and its possible impacts on our organization.
The continued ability of CREC faculty and staff to meet our
program goals and address citrus industry challenges will be
based on making some changes to insure that the funds needed
to support the program are in place. Increases in grant funding to
faculty in recent years will provide some ability to substitute for
loss of state funds. Our goal is to make adjustments as the
budget situation unfolds to avoid unnecessary personnel
reductions. Your patience is appreciated as we face the budget

MEET ... THE BRADDOCK LAB
Dr. Robert Braddock
For past 32 years, Dr. Robert Braddock, UF Professor of Food
Science. has worked on technology related to processing and citrus
Citrus by-products include the leflo\ er peel. pu Ip and other waste
products generated in juice processing, which are recovered and
converted to usable products. For example, oils from the peel are
extracted for food flavorings, while the rest of the leftover peel,
pulp and other residues are processed into cattle feed and molasses.
Dr. Braddock's work has focused on several aspects of juice and
b.-products technology, including membrane concentration and
freeze concentration, high-pressure pasteurization, feed mill air
pollution, and citrus oil recovery and quality issues. His has also
worked on viscosity problems related to concentration ofpulpwash
in citrus juices, and is currently working with his pdaduate student,
Eve Weiss, on issues related to halogenated compounds in citrus
Dr. Braddock is a native of Port Orange, Florida. He earned a BS
in Mathematics and a MS in Food Science from UF, and a Ph.D. in
Food Science from Michigan State. He came to CREC in 1970.

Dr. Braddock teaches Citrus Processing Technoloe. which was
the first course taught at CR EC. He originally taught the class in
Gainesville, but began olfcring the course at CREC after the
construction of Ben Hill Griffin. Jr. Citrus Hall. Today, it is one of
the Center's most popular courses and is taken by food science
students from CREC and Gainesville as well as citrus industry
In 1999, Dr. Braddock published the "Handbook of Citrus By-
Products and Tech-nolog ." a 247-page resource for industrial and
engineers, processors and
students. "I have tried to

About ten years ago, Rockey returned to CREC to work for the
FDOC's Dr. Paul Cancalon, and five years ago was hired by Dr.
Rockey's outside interests include karate and the martial arts.
He holds a black belt in karate and competed as a kick boxer (his
record as a professional was 10-2) and as an amateur boxer. He
also delved into Thai-style kick boxing, which Rockey describes
as "a lot rougher." with different rules than the American style of
kick boxing. Nowadays. he focuses on karate and enjoys both
the physical and mental aspects of the discipline.
Norman Nehmatallah is native of Leamington, Ontario
Canada. After graduating with a BS in Food Science and Human
Nutrition from U F, he worked in research and development in the
beverage industry. He decided to pursue a career in this area,
and entered the UF graduate program in the Department of Food
Science and Human Nutrition in Fall 2001
Norman is working towards a MS with Dr. Braddock. His
research involves developing methods for the detection and
quantification of folate in citrus juice using capillary electro-
phoresis. Folate, or folic acid, is an important vitamin found in
citrus. A major goal is to develop methods that can be used to
monitor folate concentrations during processing and storage.
Norman is currently taking Dr. Rouseffs Flavor Chemistry and
Technology course at CREC. After Norman completes his
required coursework in Gainesv ile, he will move to CREC to
conduct research in Dr. Braddock's lab.
Norman's hobbies include playing the guitar and piano and
Eve is working towards an MS in Food Science with Dr. Braddock.
After completing coursework in Gainesville, she moved to CREC
last May. Her research involves the study of halogenated
compounds in cold pressed orange oil, a citrus processing by-
product used for flavorings.
A native of Yonkers, New York, Eve moved to Jacksonville in
1990. She holds a BS in Food Science from UF and entered the
graduate program in Fall 2000.
