Duda Farm Fresh Foods, Oviedo, Fla., has added six new celery variety patents, focusing on sweeter and crisper stalks with less strings.

Duda has 33 celery patents, and is working with three new breeders (for a total of five) to support the new varieties, according to a news release.

“We are completely devoted to providing products based on consumer preferences, so we see this advancement in research necessary to deliver on this promise,” President Dan Duda said in the release. “Adding to our research program is something we are looking forward to and cannot wait to see what 2018 has in store.”

March is National Celery Month, and Duda supplies about one-third of the celery consumed in the U.S., according to the release.

Dan Duda said the research is necessary to deliver innovative new varieties. The company will also continue offering convenient fresh-cut snack packs as well, according to the release.

“It’s exciting to see how much this program has grown over the past few years and to know that our brand is committed to doing what is necessary to move the dial on innovation,” Larry Pierce, senior director of research and development/plant breeding, in the release.
