Conclusions
This investigation showed the feasibility and great advantage of
enzymatic extrusion pretreatment over traditional pretreatment
for Chinese rice wine manufacture. RSM analysis reflected MC had the most signi ficant effect on the alcoholic degree among the three parameters. Furthermore, starch molecular weight distributionre flected that oligosaccharides played an important role in improving the fermentation rate. Amino acids content showed that the new processed rice wine had higher nutrient and flavor value.
These results suggest that enzymatic extrusion is an effective pretreatment for the Chinese rice wine production. Moreover, enzymatic extrusion pretreatment is more economic, time-saving, and
environment-friendly.
