Abstract

When used in optimized proportions, sourdough can improve volume, texture, flavour, and nutritional value of bread, and may increase the shelf life by retarding the staling process and protecting bread from mould and bacterial spoilage (1). In this context, to satisfy the increasing demand for products with higher nutritional value, sourdough bread was fortified with purple potatoes, an ancient cv. Vitelotte, with purple pulp. Changes in nutraceutical properties were estimated analyzing anthocyanin contents, phenolic composition as well as antioxidant power (2, 3). The nutritional and chemical composition, together with the sensory profile were also described, following the methods reported in literature (4, 5). The preliminary results indicate that chemical composition of sourdough bread, as well as sensorial expression, might be greatly influenced by the addition of purple potato floor. In particular, bread also retained high levels of phenols, explaining its higher antioxidant activity compared to the traditional sourdough bread, and suggests that Vitelotte can represent a good source of phenols for the fortification of bread.
