Mechanical Harvesting

Gaining Momentum

by Meredith Jean Morton
Robin Bryant says she has been
'running from the get-go' in her new
position as Florida Department of Citrus
Harvesting Program Administrator.
Bryant comes from a rich agricultural
background since her father is a potato
farmer in Hastings, FL, and she worked at
the UF/IFAS research center in Hastings
while living in the area.
Bryant accepted the Harvesting Program
position in February 2004, after eight years
as an agricultural research scientist for
Tropicana. She said she has 'jumped into
the Harvesting Program with both feet,' and
anticipates further improvements in citrus
harvesting efficiency.
Research on harvesting was initiated in
the 1970s because the industry was facing
labor shortages. The current program
involves citrus researchers, growers,
harvesters and processors to improve
harvesting of citrus, while maintaining the
best interest of all parties involved. In
recent years, Bryant said the program has
focused exclusively on mechanical


"We've been looking at ways to improve
harvesting," said Bryant, who has a
bachelor's degree in soil and water science
and a master's degree in agribusiness from
She said there are three mechanical
harvesting systems currently used in the
harvesting process. While other techniques
are being considered, harvesters that shake
the trunk and catch the fruit, shake the
canopy and catch fruit, and shake the canopy
and let fruit drop, have passed the research
stage and accounted for nearly 20,000 acres
harvested last year.

While 20,000 acres is only about 4
percent of the commercial citrus acreage in
Florida, the amount represents the largest
amount ever mechanically harvested, and
Bryant is optimistic about future increases.
"I'd like to see more continued use of
mechanical harvesting," she said. "It will
come with more cooperation from everyone
involved, and that's one of my goals."
Other elements of the harvesting
program include abscission research
(directed by Dr. Jackie Burns at CREC) and
the development of robotic harvesting for
fresh fruit.
"We have been working on robotic
harvesting with the Agricultural [and
biological] Engineering Department at UF
in Gainesville to remove fruit from trees
without bruising," she said. "I have seen
the robotic arm identify fruit on a tree in a
lab and pick it off. Next we're hoping to
test this [means of harvesting] in a grove."
Bryant said this program is at least 5
years away from completion, and is looking
to cooperate with the harvesting of other
tree crops such as apples, peaches and

rent mechanical harvesting technology, the

Meet ... Dr. Zhang's Lab by Meredith Jean Morton

Dr. Jiuxu 'John' Zhang's laboratory with the Florida Department of Citrus conducts research on postharvest disease of citrus, as well
as some pre-harvest work. The mission of the research is to understand the biology of postharvest diseases, and to develop customer-
based decay control technologies to maintain citrus fruit quality, reduce post-harvest losses, and increase economic returns.
One of the primary areas of research is testing new fungicides on products to eliminate postharvest disease. Dr. Zhang said there are
three new fungicides in the process for EPA registration.
Dr. Zhang and his team are also looking for safer alternatives to currently registered products for postharvest disease elimination. Dr.
Zhang said there is importance in finding alternatives to some of the anti-disease products because of consumer concerns about chemicals
on fruit. Other studies in Dr. Zhang's lab examine how pathogens cause disease. Knowing how a disease is caused gives researchers some
clues to develop prevention strategies. With a lab located on the second floor of the packinghouse building, Dr. Zhang's team includes lab
assistants Patricia Swingle and Nicole Buker.

Dr. John Zhang
(right) has been a faculty ,
member of the Florida i
Department of Citrus as a "
research scientist II since
1999. A native of China, i...
Dr. Zhang came to the -
United States in 1990 to
pursue his Ph.D. in plant
pathology from Texas A &
M University. His
bachelor's and master's
degrees in plant
protection are from the Northwest
Agricultural University in China. Before
coming to the U.S., Dr. Zhang worked as a
research scientist from 1982-1990 at the
Cotton Research Institute for the Chinese
Academy of Agricultural Sciences.
After receiving his Ph.D., Dr. Zhang
worked at a USDA-Agricultural Research
Service facility in Oklahoma, where he
studied postharvest disease on a variety
of melons.
Dr. Zhang said he chose an agricultural
major in college because he was raised in
the countryside of China, however, he said
when he started college, engineering was
his first choice for a major. Later Dr. Zhang
said he discovered 'agriculture was not so

Flavor is First for
Dr. Valim
by Meredith Jean Morton
For Dr. Filomena Valim, the
perfect glass of citrus juice is fruity
and sweet, with some green notes,
and she particularly likes orange
juice because of its balance
between sweetness and sourness.
As a researcher in the sensory
analysis of juice, Dr. Valim
transferred two months ago from a visiting
scientist position with Dr. Russell Rouseff

15-year-old daughter, Lisa,
and a son, Jack, who is almost
-- 10.
In his free time, Dr.
Zhang plays tennis and
enjoys fishing. He and his
family also like to travel,
especially to places with
historic significance or
natural beauty.

Patricia Swingle is a
biological scientist who Dr.
Zhang said "does all kinds of work for the
projects." She has been working in Dr.
Zhang's lab for the past ;
18 months, and works |

Originally from Kentucky, Nicole chose
to attend college at UF because of its repu-
table engineering school. She would still
like to pursue a career in engineering, or in
her other interest, forensic science.

Sensory quality is the result of the
interaction of the food characteristics with
the human senses.
"Flavor preference involves the person's
history, social, economic, cultural and
physiological backgrounds," said Dr. Valim,
who has a Master's degree in food science
and a Ph.D. in food technology from the
State University of Campinas in Brazil. "And
it can be affected by a person's emotions."
The varied flavor preferences result in
the variety of citrus products in the grocery
store, Valim said.

hometown of Niceville.
Kristin is a UF graduate
student in Dr. Rouseff's
lab. They met as
chemical engineering
undergraduates at
Georgia Tech in Atlanta.
Kristin is working on her
masters degree in Food
Science/Flavor Chemistry,
studying the effects of light and oxygen on juice flavor and the
development of potential off-flavors. This area of research is
pertinent to the increasing use of clear plastic containers for
citrus juices. After completion of her degree at the end of the
year, Kristin will work for the flavor company, Mastertaste, Inc., in
Lakeland. Jared is a chemist for Florida Distillers in Lake Alfred.

changes to personnel and business practices.
Some brief presentations will be offered, but the
primary purpose is to discuss changes such as
elimination of Voyager Gas Cards, use of SHARE
funds, and time-keeping, leave and payroll.
Hopefully, your questions and concerns can be
addressed. By July 12, we will have experienced
one full payroll cycle and should have the 2004-
05 CREC budget in place. This meeting is
requiredfor allIFAS CREC employees unless
you already have out-of-town plans. The
Center Director's office will appreciate an e-
mail ifyou are unable to attend.

Finally, we are nearing the final stages of
development of a UF, IFAS, CREC Strategic plan,
a process whichbegan in October 2003. Changes
in the industry that we serve, and loss of faculty
at CREC, UF and IFAS demand that we look
ahead and formulate plans for programs, faculty
and staff, facilities, and how to continue to grow
our funding. A dedicated team has been meeting
monthly with extensive follow-up with faculty
and the citrus industry. We anticipate that the
initiatives that will guide us towards 2010 and
beyond will be defined and ready for
presentation to the entire CREC community and
ourvarious clients by this fall. Then, the task of
turning the plans into actions will begin. I
appreciate the support of the Center and the
industry as we take this important step, and look
forward to working with all of you to imagine a
future course for CREC.
Thanks to all of you for your part in the success
of CREC!

Meet .Dr. Pat Tomlinson by Meredith Jean Morton

As a visiting scientist
at CREC, Dr. Pat
Tomlinson feels like she
is coming home.
Tomlinson, who is visiting
Dr. Ed Exteberria, had her
first postdoctoral
fellowship at the
University of Florida in
Gainesville; citrus was
the focus of this post-
doctoral position as well
as her Ph.D. dissertation. Dr. Tomlinsonis
pleased to be working at CREC.
Originally from the Virginia foothills of
the Blue Ridge Mountains, Dr. Tomlinson
is an assistant professor of biology at Berry
College in northwest Georgia, teaching
introductory biology to undergraduate
majors and non-majors.
Dr. Tomlinson has aPhD. inbotany from
the University of California Riverside,
where she studied with Dr. Carol Lovatt (and
shared an office withDr. Debbie Sipes, wife
ofDr. Bill Dawson, who was also a graduate
student at the time). She and Dr. Exteberria
are examining endocytotic mechanisms for
sucrose uptake in plant cells.
In the process of endocytosis, a portion
of the cell plasma membrane invaginates
and pinches off a membrane-bound vesicle,
something akin to "plant cells gulping
food." Understanding processes
associated with sucrose metabolism can
help us understand processes important to
plant growth, including fruit development.
Inadditionto this project, Dr. Tomlinson
and Dr. Exteberria are also working on a

Harvesting Program strives to educate the
citrus industry about advances in harvest-

"We try to interest the growers in try-

benefits," Bryant said. "It can increase the
productivity anywhere from two to ten
times over hand labor."
She added that with increased use of
mechanical harvesting, the cost of harvest-
ing could be reduced by half.
"We may never reach 100 percent me-
chanical harvesting in Florida, but my goal
is to get as close as possible," Bryant said.
"We've reached four percent and the num-
bers are still increasing."

"Each of us brought a
project to work together
on," said Dr. Tomlinson of
the projects on which she
and Exteberria will be
collaborating. "I have
been working with northern red oak for about
13 years."
Dr. Tomlinson worked with the northern
red oak trees while a scientist for the forest
service in Rhinelander, Wisconsin.
Dr. Tomlinson began searching for a
position at a university while working for
the forest service because she always wanted
to teach. She had visiting professorships at
the College of Charleston, in South Carolina,
and at Washington and Jefferson College,
in Pennsylvania, before beginning her
current position at Berry College four years
Dr. Tomlinson said she will be at CREC
working with Exteberria for about a month.

Dr. Valim ... from page 3
"We have different products for
different people," she added.
Dr. Valim said orange juice flavor is a
very complex mixture in specific
proportions, with over 200 volatiles, not all
aroma active.
Different levels of these volatiles
produce a variety of sweet, fruity, green,
floral and other flavors in orange juice,
giving it a different sensory quality.
Dr. Valim said she has always liked
chemistry but wanted to pursue a more
practical application. She found her
practical application in food chemistry.
Growing up inAraras, Brazil, Dr. Valim
was raised breathing in the chocolate
aromas from the Nestle chocolate plant in
her hometown. She also had several family
members who worked for the food industry.
This exposure to food science
encouraged her to become a food engineer,
later teaching quality control, food
technology and sensory analysis at Sao
Paulo State University in Brazil.
Dr. Valim said she would like to do more
specific sensory analysis on citrus juice
while working for the FDOC to help the
citrus industry especially marketing
programs to understand and provide what
consumers want.
"I'd like to select and train my own test
panel for flavor analysis," she said. "They
would be trained to identify the different
flavor notes, so they could give more
descriptive analysis of citrus juices."
Dr. Valim's husband, Marcos, is also
involved with the citrus juice industry,
working for Citrosuco, North America, in
Lake Wales. They have three sons, Gabriel,
17, Rafael, 15, andHenrique, 12.
"I am very happy to be here," said Dr.
Valim, who as a Ph.D. student in Brazil,
would read material referencing scientists
at CREC. "It is an honor and a pleasure to
be a part of CREC as a research scientist."

Dr Valim received her bachelor degree
in food engineering, master 's degree in
food sicence and a Ph.D. in food
technology from the University of
Campinas in Brazil. Incidentally, CREC's
Dr Chin Su Chen, retired UF Professor of
Food Engineering, chaired the Food
Engineering Department at the University
of Campinas in the 1970s, where he was
instrumental in establishing the food
engineering program.
