The attributes investigated were mash temperature, mash pH, liquor-to-grist ratios, boiling times, kettle fining additions, and microbial gluten reduction by different lactic acid bacteria. Gluten concentrations were analyzed using a competitive ELISA assay. A trained sensory panel evaluated samples that were produced with a combination of yeast and bacteria using difference testing and descriptive analysis. The results indicate that some lactic acid bacteria can reduce gluten below the detection limit of the ELISA assay. Other treatments such as boiling time, mash pH, or the liquor-to-grist ratio can reduce gluten significantly but do not come close to that reduction level. On the other hand, sensory testing revealed that beers produced with lactic acid bacteria might not meet consumer expectations owing to unusual descriptors such as sweaty, earthy, and fishy. However, if used under controlled conditions, lactic acid bacteria are a promising treatment option to degrade gluten protein in beer.<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u200bMicrobial Gluten Reduction in Beer Using Lactic Acid Bacteria and Standard Process Methods Brett F.
