Optimisation of Malting Parameters for Quinoa and Barley: Application of Response Surface Methodology

Quinoa (Chenopodium quinoa Willd) is a nutritious pseudocereal that more stress-tolerant compared with traditional cereals. It an excellent example of climate-smart crop resilient to climate change barley. The purpose the study was investigate optimum malting conditions required produce malt using barley as control. Response surface methodology (RSM) used influence two parameters steeping time and germination on Brix (wort extract), diastatic power (DP), free amino nitrogen (FAN) malt. temperature set at 15°C during process. Steeping ranging from 12 48 hours 24 96 were designed central composite design (CCD). kilning for all malts 65°C. For malt, there notable weak positive correlation between (r = +0.119). However, strong +0.893). A similar trend noted +0.142). also recorded +0.897) There relatively stronger FAN +0.895) than +0.275) in values 47.68 hrs 82.55 desirability value 1.00. responses optimised 8.25°Bx, 162.28 mg/L, 271.69°L Brix, FAN, power, respectively. To 8.37°Bx, 165.60 275.86°L, respectively, 47.69 95.81 are required. very good candidate producing high-quality brewing
