Arcadia Biosciences and DuPont Pioneer Achieve Milestone in the Development of High-Value Specialty Oil

— Arachidonic Acid Oil Produced in Safflower Provides Cost-Effective
Source for Critical Nutritional Oil Ingredient —

DAVIS, Calif., & DES MOINES, Iowa–(BUSINESS WIRE)–Arcadia Biosciences, Inc. (Nasdaq: RKDA) and DuPont Pioneer (NYSE: DD)
today announced the successful field-trial validation of safflower
plants that produce high levels of arachidonic acid (ARA) oil, a
high-value, specialty nutritional oil for global consumer markets. The
achievement of this key milestone represents a significant step in the
collaboration between Arcadia and DuPont Pioneer to develop a new
plant-based and cost-effective source of oil with high levels of ARA.


ARA is an omega-6 fatty acid that, along with certain omega-3 fatty
acids, plays a critical role in neural and visual development of
infants. It is one of the most abundant fatty acids in the brain, and
neurological health is reliant upon sufficient levels of ARA.

ARA is used as a functional ingredient in many infant nutrition
products, and has been shown to provide developmental benefits similar
to breastfeeding. Its use in nutritional products has been reviewed and
supported by the U.S. Food and Drug Administration, the Food and
Agriculture Organization of the United Nations and the World Health
Organization. High ARA safflower plants will offer an alternative and
more efficient source for the ingredient that will improve manufacturing
economics and encourage wider use of ARA.

“The newly developed safflower oil could ultimately provide a renewable
and sustainable source of this nutritionally important fatty acid. Since
sunlight provides all the energy needed to make ARA in safflower seed
oil, this production technique also is very cost-effective when compared
with current commercial methods,” said Tony Kinney, research director,
DuPont Pioneer.

“The achievement of this milestone further demonstrates Arcadia’s
expertise in developing high-value nutritional oils leveraging our
omega-6 platform,” said Raj Ketkar, CEO of Arcadia. “The development of
ARA safflower oil will expand Arcadia’s nutritional oil offerings and
will build on our experience in the development, regulatory management,
production and marketing of these high-value products.”

Arcadia’s ARA safflower oil is in the late stages of product
development. Regulatory approval would be sought prior to
commercialization.
