Evaluating the Role of Mashing in the Amino Acid Profiles of Worts Produced from Gluten-Free Malts

description | A successful wort fermentation depends on both the sugar and the free amino nitrogen (FAN) content of a wort. The primary goal of the mashing step is to generate fermentable sugars, as FAN is regarded as being primarily determined by malt quality; however, the role of mashing in modifying FAN has not been extensively studied, especially with respect to non-barley brewing materials. In this study, the FAN content of gluten-free (GF) worts varied greatly from barley (73–490 mg/L vs. 201 mg/L, respectively) and yielded different amino acid profiles, including lower proline and higher γ-aminobutyric acid concentrations. While most of the amino acids were present in the malt or generated in a brief window early in the mashing, significant increases in amino acid concentrations could be generated by mashing at temperatures below 55 °C. Overall, GF malts are promising brewing ingredients that can produce quality worts if appropriate mashing conditions are implemented. |
