Yacon and maca are two South American superfoods, associated with countless health benefits. Yacon is a tuber recognized for its beneficial effects on digestive health and diabetes.1 Maca, on the other hand, is a nutritional powerhouse known to restore hormonal balance and boost stamina, as well as for improving fertility and libido.2,3 This study intended to verify the viability of yacon and maca as flour substitutes for baking by partially replacing wheat.
Researchers in this study baked a chocolate cake using three types of flour: wheat, yacon, and maca. Each cake was baked with two or three different flour compositions: 1) wheat, yacon, and maca; 2) yacon and wheat; and 3) maca and wheat. The tasters evaluated the samples using a free-choice profiling method, which required them to describe the cake's appearance as well as its texture, aroma, and taste.
The study has found that the chocolate cake baked with higher maca content was characterized with more brownness, as well as burnt aroma and taste. Chocolate cake made with higher amounts of yacon powder resulted in a more attractive appearance. It was also described as being softer with a sweeter and chocolatier flavor.
What Does This Mean?
In the recent years, celiac disease and gluten intolerance have been on the rise, as well as diabetes and obesity, which calls for an exploration of other sources of non-gluten flour, as well as low-calorie alternatives in order to substitute, partially or completely, wheat flour in baking. Maca and yacon root powder candidates are particularly beneficial due to their added medicinal effects on health. To produce baked goods that are completely gluten-free other wheat flour substitutes include amaranth flour, banana flour, maize flour, and coconut flour.
