In a 2009 study published by the Institute of Food Technologists in the Journal of Food Science found that using a griddle to cook or roast vegetables was among the best ways to maintain the level of antioxidants. Compared to boiling, pressure-cooking, baking, microwaving and frying, griddle cooking was found to be among the best methods for preserving these important antioxidants. According to the study, certain types of vegetables could lose as much as 50% of their beneficial antioxidants depending on the cooking method. With Microwave Heating, Griddling, or the Baking Process, ascorbic acids and antioxidants are released at a smaller rate than with pressure-cooking, boiling, or frying. However, the results of the study found that Microwave Heating and Griddle Cooking were the best at protecting and maintaining essential antioxidants.
“Griddle- and microwave-cooking helped maintain the highest levels of antioxidants, produced the lowest losses while “pressure-cooking and boiling [led] to the greatest losses,” says lead researcher A. M. Jiménez-Monreal. “In short, water is not the cook’s best friend when it comes to preparing vegetables.”
With the Steam Shell Griddle, by the American Griddle Company, vegetables are evenly cooked across unvarying temperatures helping to retain product moisture and important antioxidants. When preparing vegetables on the Steam Shell Griddle, cook times are reduced by up to 50% on most items.
