Description The current study is focused on optimizing the parameters involved in enzymatic processing of red rice bran for maximizing total polyphenol (TP) and free radical scavenging activity (FRSA). The sequential optimization strategies using central composite design (CCD) and artificial neural network (ANN) modeling linked with genetic algorithm (GA) was performed to study the effect of incubation time (60–90 min), xylanase concentration (5–10 mg/g), cellulase concentration (5–10 mg/g) on the response, i.e., total polyphenol and FRSA. The result showed that incubation time has a negative effect on the response, while the square effect of xylanase and cellulase showed positive effect on the response. A maximum TP of 2,761 mg ferulic acid Eq/100 g bran and FRSA of 778.4 mg Catechin Eq/100 g bran was achieved with incubation time (min) ¼ 60.491; xylanase (mg/g) ¼ 5.4633; cellulase (mg/g) ¼ 11.5825. Furthermore, ANN-GA-based optimization showed better predicting capabilities as compared to CCD.
