Abstract
Bran of barley causes high viscosity in bioethanol production due to the large amount of ${\beta}$-glucans and fiber. High viscosity is the main cause of decreased productivity and decreased facility efficiency in ethanol production. In order to prevent high viscosity, this study investigated the possibility of bioethanol from barley by debranning. As a result, it was able to reduced the viscosity (22.8 cP to 17.5 cP). And the fermentation speed and yield were improved as the activity of the enzyme and activity of yeast was also increased was improved due to the removal of non-fermentable components. In conclusion, debranning was advantageous in two ways. Firstly, bran removal increased the starch content of the feedstock and decreased viscosity of mash, improving ethanol fermentation. Secondly, by-products produced by debranning can use valuable products. It was remarkable results to the feasibility of bioethanol production from debranned barley.
