Sugary biomass contains sucrose as a sugar source, a disaccharide consisting of glucose and fructose, which are both hexose monosaccharides (C6) (Fig. 2). Sucrose undergoes hydrolysis to release glucose to be converted into 1G ethanol via fermentation using a S. cerevisiae yeast (Oh et al. 2012).

Examples of sucrosic biomass include sugarcane and sweet sorghum, the lat­ter of which has a considerable concentration of free monosaccharide D-glucose when compared with sugarcane (Table 3). Sugarcane has a high content of sucrose which releases glucose after a hydrolysis step, and it is the most relevant feedstock for 1G ethanol production. However, sweet sorghum could be used as a comple­mentary crop during the sugarcane off season.

Analytical data are important for these feedstocks because we can obtain sugars content for bioethanol production. Then, we can monitor the process of conver­sion, their yields, and the product quality. It could be seen in the item 3.1.
