- Abstract
The lingonberries represent a valuable resource for many sectors of the food industry in a wide variety of both organic and conventional products. In the context of little information on the use of dried and ground lingonberries mixed with flour in bakery processing, this study aimed to evaluate how the use of spelt wheat flour fortified with dried lingonberry powder in the preparation of cookies, muffins, and brioches with different types of dough can improve their nutritional, functional, and sensory properties, and the degree to which the rheological properties of the dough are affected. The results of the proximate composition analysis revealed that the use of fortified flour in the pastries matrix led to a significant increase in mineral content by an average of 9% and a reduction in protein content up to 7% progressively with the concentration of fruit powder in fortified flour, relative to control samples. The phytochemical profile of pastry products led to a statistically significant enhancement by using fortified flour in their manufacturing formula, with results showing increases of 10 times in total flavonoids content, 9.3 times in total phenolic content, up to 2 times in DPPH (1,1-diphenyl-2-picrylhydrazyl) radical inhibition ability, and for FRAP (ferric-reducing antioxidant power), with values of 14.8 times relative to the control in cookies. The rheological behavior highlighted that the mixing of lingonberry powder with spelt flour is suitable for dough prepared with liquid in order to form gluten up to 15% of fruit addition. The best rated from a sensory point of view were muffins prepared from flour fortified with 10% lingonberry powder. The data resulted from this research suggest that the inclusion of lingonberry powder in spelt wheat flour consists of a promising solution to develop innovative pastry products with improved functional properties.
