Vegetables, like people, urged to live up to potential

COLLEGE STATION Carrots may be underachievers. Healthy and good for one's eyes, yes, but they could be so much more, researchers say.

A major stress in a carrot's life like the slash of a kitchen knife and the tapered tuber kicks in the juice and pumps up its phytochemicals.

That's the finding of Dr. Luis Cisneros, Texas Agricultural Experiment Station food scientist. He calls it abiotic stress pushing the button, so to speak, on a crop after it has been harvested.

"What happens is that on many occasions, plants do not express their real potential. They can actually express more if they are challenged to a point," he said.

"It's something similar to what would happen with people. You stress people, and people tend to respond more to the challenges in front of them," he added. "In this case, when you stress plants, you actually trigger this genetic response, and the plant will synthesize chemical compounds. You end up with a carrot that is healthier than the original carrot in a short period of time with a very cheap and easy stressor."

A key to his research was understanding the plant's pathway to a specific, desired compound and getting it to increase only that one. So far, his lab has successfully increased the amount of antioxidant activity in carrots up to five times.

The finding is important for food processors, Cisneros said, because as companies increasingly seek ways to add healthier components to foods, the technique could yield more of those desired substances.

One kilogram of anthocyanin extract is valued at $1,000 in the marketplace, Cisneros said. Anthocyanin is the red pigment in vegetables which is associated with a reduced risk of cancer and heart disease.

"So, if you stress (carrots) and they accumulate more anthocyanin, that means more money," he said. "Now imagine using that carrot to make a juice or making an extract of it that could be added to bread or some o
