Interpretive Summary: The results of the present study show that exposing five commercial fresh-cut carrot products (baby carrots, carrot sticks, shredded carrots, crinkle cut coins, and oblong chips) to a form of ultraviolet light known as UV-B, found in sunshine, can boost the antioxidant activity of the colorful veggie. UV-B exposure has the potential to increase the nutritional value of commercial fresh-cut carrot products.

Technical Abstract: The results of the present study show that exposing five commercial fresh-cut carrot products (baby carrots, carrot sticks, shredded carrots, crinkle cut coins, and oblong chips) to UV-B radiation can significantly increase the antioxidant capacity of carrots. Optimization of the nutritional beneficial effects of UV-B exposure is correlated to increasing exposure area of fresh-cut carrots. UV-B exposure has the potential to increase the nutritional value of commercial fresh-cut carrot products.
