Evaluation of a gluten-free sourdough bakery product

Abstract

The population of gluten sensitive people has been gradually rising in the last decades. The food industry, especially the bakery industry has to develop more gluten-free products to satisfy the consumer ’ s demand. However, the quality of these products differs from the quality attributes of a standard glutenious bakery product. Therefore, the aim of our research was to develop a good quality gluten-free sourdough product with 3 different gluten-free fl ours: millet, brown rice and a commercially available mixture (Belbake). We investigated the differences in moisture content, the baking loss, the texture and the sensory properties of the products. According to our results in the case of the moisture content the brown rice sample had the highest, while the millet gave the lowest value. The baking loss measurement gave reverse results. In the texture analysis the brown rice sample was the softest, but the millet and the Belbake had better results in resilience and in springiness. Also, in the sensory analyses the Belbake product was found to be the best by the judges, however, there were no signi fi cant differences between them. In conclusion, the product development of a gluten-free sourdough bakery product was successful. Further research is needed to investigate the shelf life of the products.
