A gluten-free (GF) diet is recognised as being the only accepted treatment for celiac disease—a permanent autoimmune enteropathy triggered by the ingestion of gluten-containing cereals. The bakery products available in today’s gluten-free market are characterised by lower palatability than their conventional counterparts and may lead to nutritional deficiencies of vitamins, minerals and fibre. Thus, the production of high-quality gluten-free products has become a very important socioeconomical issue. Microbial fermentation by means of lactic acid bacteria and yeast is one of the most ecological/economical methods of producing and preserving food. In this review, the role of a fermentation process for improving the quality of GF products and for developing a new concept of GF products with nutraceutical and health-promoting characteristics will be examined.
