A non-conventional process for producing gluten-free bread
Italian Researchers from the University of Milan published on International Journal of Food Science & Technology a work regarding the production of gluten-free bread.
Gluten-free (GF) sourdough was prepared from wheat sourdough and analysed both in fresh (GFS) and dried forms (DGFS). The gluten content in each GF sourdough sample was <20 mg kg-1. The dough leavening capacity and the properties of the bread samples were investigated and compared to those of bread prepared using bakery yeast (Saccharomyces cerevisiae). Two commercial rice-based mixtures (different for the presence/absence of buckwheat flour) were used to prepare bread samples. In GFS, lactic acid bacteria (LAB) and yeasts were found in amounts corresponding to 108 and 107CFU g-1, respectively, whereas both LAB and yeasts were detected in lower amounts (about 106CFU g-1) in DGFS. When used in bread-making, both GFS types produced significant dough acidification and exhibited good dough development during proofing, resulting in loaves with specific volume values between 3.00 and 4.12 mL g-1, values similar to those obtained for reference bread (3.05/4.15 mL g-1).
The use of GFS was effective in lowering the bread staling rate during storage for up to 7 days. copyright 2015 Institute of Food Science and Technology.
