Citrus Processors Day Recap
Flavor, Quality, Health
Benefits, Food Safety Among
The Day's Topics
LAKE ALFRED The intricacies of citrusjuice flavor, the
potential health benefits of citrus and food safety were
among the topics at the 52"r Annual Citrus Processors

born in Tampa and grew up north of Lakeland. His profes-
sional career started at the American Can Co., site of canning
operations for Lvkes-Pasco in Dade Cit "That's where I got
a lot ofn m engineering training," said Dr. Ahrens.
Dr. Ahrens earned a B.S. in Aericulture from the Univer-
sity of Tennessee, then worked as a technician for the t-DOC

degree from LI F, orkinu v ith Dr. Charles Barmore, During
that time, he witnessed notable Center milestones such as the
dedication oflhe Ben Hill Griffin, Jr. Citrus Hall and the
construction of Building 24's three-story addition.
Dr. Ahrens earned his Ph D from U F in Vegetable Crops,
where he worked with Dr. Don Huber in the area of cell wall
physiology. From there he went to the University of Califor-
nia, Davis, where he directed an Extension program in the
marketing and distribution of fruits.
Dr. Ahrens also worked in Europe for Freshconsult, an
international consulting firm. Most recenil;,. he served as Sr.
Director for Engineering and Technical Services for EPL, a
company involved in the marketing and technology of fresh-
cut foods for Green Giant,
"Now I've returned back to the DOC," said Dr. Ahrens,
who is relocating to Lake Alfred. He has two daughters and a
son who are grown, and a 15-year old daughter who is a

Dr. John Paul Praal returned to New Zealand after a
month-long stay at CREC, where he worked with Dr. Bill
Miller in the area of precision agriculture. Dr. Praat
works tbr Lincoln Ventures Ltd. in Hamilton. New
Zealand, where he is using precision agriculture
technology to collect and analyze data for fruit qualil
yield and pro lii in apples, grapes and kiwi. At CREC,
Dr. Praat did some work with comnpuler- LneLrated tree
grids for tree size mapping in citrus, visited several
citrus operations and met several people working in
agricultural engineering and precision agriculture.

Dr. Bo Li
Dr. Bo Li is an agricultural engineer working with Dr. Jodie Whitney, Dr.
Bill Miller and the precision agriculture tean at CREC. A native of Beiling, ,s
China, Dr. Li has a bachelor's degree from Luoyang Institute of Technology ." ,
in the Hunan Province and a Master's and Ph D from Beiling .\riculrural
University, where he is a facult- member. In 1900, came to the U.S. to work
with Dr. Dennis J. Murphy at Penn State in the Department of Agriculrural .
and Biological Engineering. His work involved developing daringg devices
for tractor drivers when tractors are driven on steep slopes to prevent
accidents. This is a serious problem in mountainous areas such as
Pennsylvania, said Dr. Li, who added that there are approximately 40
fatalities a year due to tractor accidents.
Since Dr. Li's arrival at CREC in August, he has been working on ultrasonic
sensors to measure citrus canopy volume. He also plans to become involved in a
Project with Dr. Adair Wheaton to analyze vibrations and pressure distribution in
,j trees subjected to mechanical harnesling with trunk shakers.
