Success Story

  • Avocolor uses avocados to make food dye.

Invent Penn State’s Fund for Innovation awarded $75,000 to help jump start natural food color venture, Persea Naturals

One of the latest ventures to come out of Penn State, Persea Naturals began with an unintended discovery. Gregory R. Ziegler, professor of food science in the College of Agricultural Sciences, was extracting starch from avocado pits when he noticed something interesting. When avocado pits are pulverized, an enzymatic reaction produces a bright orange color. After extracting the starch, Ziegler just couldn’t get the color to wash away.

Piquing his curiosity, this observation launched a multiyear research endeavor to identify the colored compound alongside Joshua Lambert, associate professor of food science.

“I couldn’t believe that this reaction hadn’t been described before,” said Ziegler, “and with a growing consumer interest in natural food colors, the timing couldn’t have been better.” “I enjoy working in ‘Pasteur’s Quadrant,’ conducting fundamental research with a practical application. It’s a prime reason I landed in food science.”

The pair’s research, which proved both the stability of the color, and the wide spectrum of orange, yellow and red hues available, led them to a simple conclusion: the substance would be a perfect natural food color.

Persea Naturals was born, with plans to bring a natural food color product line, AvoColor, to the commercial market. Persea comes from Persea americana, the scientific Latin plant name for  the avocado plant.

Along the way, the young company has taken advantage of several programs funded and supported by the Invent Penn State initiative, which helps university researchers through the commercialization process.  After receiving an initial RAIN grant through the College of Agricultural Sciences, the researchers worked with Penn State’s Smeal College of Business to better understand the marketplace opportunity. They also turned to the Office of Technology Management for legal and technical assistance with their patent application and subsequent licensing of the technology. The team also participated in the TechCelerator @ State College, an intensive business accelerator run by Ben Franklin Technology Partners co-located in Innovation Park. Last October, the team won $50,000 at the Invent Penn State Venture & IP Conference in the Penn State Tech Tournament. They have received funding, facilities and strategic guidance from Invent Penn State and its partners that has helped to refine the Persea Naturals business plan and position the company for growth. Recently, the company brought in a seasoned CEO, Bob Hicks, to run the company.

Another significant milestone was receiving a $75,000 jumpstart funding from Invent Penn State’s Fund for Innovation.

“We have been fortunate to have received strong support from the University as we moved onto this path,” said CEO Bob Hicks. “We knew from the research that we had something unique, but the funding and entrepreneurial-focused resources from Invent Penn State have allowed us to transition our idea from the lab into a viable business.”

Their opportunity is a big one. Food and beverage manufacturers are increasingly looking to replace artificial ingredients with natural ones. Not only is AvoColor more vibrant and stable than most other natural options, it’s likely to be extremely cost-effective. The source, avocado pits, are currently discarded in large volumes by the prepared food and restaurant industries.

What’s next? Persea Naturals researchers have already tested their product with a major manufacturer. AvoColor has been highly successful in nearly every test, whether it’s added to dairy products, baked goods, or beverages.

“There is extremely high growth potential for Persea Naturals.  The commercialization of AvoColor could dramatically accelerate the elimination of artificial colors from foods,” noted Josh Lambert. “We are looking forward to introducing this unique offering to the marketplace, and to continuing our research and innovation as we grow as a business.”



About the Fund for Innovation

A signature program of the Invent Penn State initiative, the Fund for Innovation aims to de-risk and accelerate the development of Penn State’s commercially promising research for the purposes of licensing or venture formation. The program is a collaboration between Invent Penn State, the Office of the Vice President for Research and the academic colleges. Since its founding, the program has supported nearly 50 emerging Penn State technologies, resulting in 7 new ventures.
