Banana peel or skin is making its way onto the plates of resourceful consumers, replacing pork in ‘pulled peel’ sandwiches and getting fried up into ‘bacon’.

It has now been revealed 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, claim researchers reporting in ACS Food Science & Technology. 

Amid rising interest in plant-based diets and in ways of reducing food waste, food businesses and end consumers are seeking creative ways to use every part of their vegetables and fruits.

Chefs and home cooks are experimenting with banana peels, but these skins are extremely fibrous, making them unpleasant to eat raw.

Scientists recently found that they can grind the peels into a flour that’s rich in fibre, magnesium, potassium and antioxidant compounds. 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 flavours.

Researchers at Aligarh Muslim University in India decided to go further and conduct similar experiments with cookies, substituting some of the wheat flour in sugar cookies with banana peel flour, then 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.
