Banana peels make sugar cookies better for you
“Effect of the Addition of Banana Peel Flour on the Shelf Life and Antioxidant Properties of Cookies”
ACS Food Science & Technology
Banana peels aren’t always destined for the trash or compost anymore. They’re making their way onto people’s plates, replacing pork in “pulled peel” sandwiches and getting fried up into “bacon.” And now, researchers reporting in ACS Food Science & Technology show that incorporating banana peel flour into sugar cookie batter makes the treats more healthful. In taste tests, cookies enriched with some banana peel flour were more satisfying than those baked with wheat flour alone.
Interest in plant-based diets and reducing food waste is increasing, and people want creative ways to use every part of their vegetables and fruits. Banana peels are one such waste that chefs and home cooks have been experimenting with, but these skins are extremely fibrous, making them unpleasant to eat raw. Recently, scientists found that they can grind the peels into a flour that’s rich in fiber, magnesium, potassium and antioxidant compounds. And when small amounts of wheat flour in breads and cakes were replaced with the new flour, the baked goods were more nutritious and had acceptable flavors. However, similar experiments haven’t been widely done with cookies. So, Faizan Ahmad and colleagues wanted to substitute some of the wheat flour in sugar cookies with banana peel flour, assessing the cookies’ nutritional quality, shelf-stability and consumer acceptance.
To make banana peel flour, the researchers peeled ripe, undamaged bananas and then blanched, dried and ground the skins into a fine powder. They mixed together different amounts of the powder with butter, skimmed milk powder, powdered sugar, vegetable oil and wheat flour, creating five batches of sugar cookies, and baked them.
