Fermentable oligosaccharides, di- and monosaccharides, and polyols defined as FODMAPs readily trigger the symptoms of irritable bowel syndrome (IBS), which affects up to 23% of the population, through several mechanisms. A low-FODMAP diet is a short-term solution due to significant nutrient deficiencies, especially in dietary fibre (DF). IBS patients must avoid cereals, especially wholegrain cereals such as wheat and rye, which are an important natural source of DF and therefore FODMAPs (part of soluble DF). This study is the first of its kind to employ biotechnological tools for the creation of wholegrain low-FODMAP cookies and crackers based on wholegrain wheat and rye flours with high FODMAP contents. Endogenous enzymes activated via prolonged dough resting and exogenously activated enzymes originating from chicory extract, wheat malt, and baker&rsquo:s yeast were employed. The prolonged dough resting time and the addition of wheat malt reduced the FODMAP content in the wholegrain wheat and rye cookies by 46% and 99.5%, respectively. The best result was achieved in the wholegrain wheat crackers, with a FODMAP content reduction of 59.3% based on the combination of a prolonged dough resting time and the addition of wheat malt and baker&rsquo:s yeast. In the wholegrain rye crackers, a prolonged resting time alone was sufficient to achieve an 83.6% reduction in the total oligosaccharide content.
