Abstract

  Distillery dried grain with solubles (DDGS) is a byproduct generated from alcohol industries. Heavy production of alcohol generates tones of DDGS round the year, whose handling becomes difficult, which leads to adverse effects on environment. Considering valorization, DDGS is a protein rich substrate which could be converted into high value products. However, extraction of protein from DDGS is a complex process; therefore, an efficient extraction method is required for maximizing protein recovery. In an attempt to overcome this bottleneck, central composite design (CCD) based response surface methodology (RSM) was used to evaluate and optimize the effect of different process parameters such as temperature, pH, solid loading, incubation time, and reducing agent on protein extraction from DDGS. From the optimization study, it can be deciphered that the maximum protein extraction (51.23 ± 0.03%) from DDGS takes place at 73ᵒC at pH 11.5, 15% (w/v) solid loading within an incubation time of 87 min in the presence of 0.5% reducing agent. Furthermore, temperature and pH were the significant factors that determined protein extraction efficiency. In order to validate the obtained results, experimental extraction process has been compared with the predicted extraction percentage that showed a high coefficient of 0.9919, thereby, assuring the model’s adequacy.
