“…Limit dextrinase is a starch-debranching enzyme that cleaves amylopectin α-1-6 glycosidic bonds [19,40] and releases linear amylopectin chains. On average, the limit dextrinase activity in the rice malts was 4255 U/kg dm; this is ~6x times higher than the limit dextrinase activity reported in barley (349-800 U/kg) [16,19,41,42]. The highest activities were found in cultivars #2 (6500 U/kg dm), #17 (5423 U/kg dm), #18 (5212 U/kg dm), and #14 (5085 U/kg dm) (Figure 2E).…”

Nineteen globally diverse rice cultivars were analyzed for various chemical parameters important to malting, including germination energy, protein, apparent amylose content, and gelatinization temperatures (GT). The rice cultivars were then malted, and congress mashes were produced. Several parameters important to brewing were then assessed in the malts and worts (i.e., extract, soluble protein, free amino nitrogen (FAN), GT, etc.). The rice malts produced were saccharified to varying degrees, had high limit dextrinase activities, and contained sufficient FAN/protein concentrations. This suggests their potential to yield robust fermentations in beer styles with high adjunct inclusions without requiring additional nitrogen supplementation. Rice cultivars with purple-pigmented bran were found to yield unique wort colors and could serve as novel natural gluten-free colorants for future recipes. Overall, these findings suggest that malted rice could offer a more local and gluten-free source of starch for brewers and beverage/food producers.
