Avaliação do processo de hidrólise enzimática para obtenção de açúcares a partir de gengibre (Zingiber officinale)

Ginger is a starchy tubers prized for their chemical components. In the production of any kinds of beverages has been added to the extract of ginger. However, in view of the high starch content, a possibility of further development of the agribusiness sector this would be the hydrolysis tuberous rhizomes disqualified for export in order to obtain hydrolysates that would be used in the preparation of fermented beverages. This work aimed to evaluate the production of sugar from rhizomes of ginger. Two α-amylase enzymes were tested in the stage of liquefaction (Liquozyme Supra (T1) and Termamyl 2X (T2)), as well as the effect of time of action of amyloglucosidase (AMG 300L). The hydrolysates were analyzed in liquid chromatography (HPLC) and was also carried out the mass balance of the processes. The results showed higher hydrolysis of starch in the treatment that used Liquozyme Supra in liquefaction. The action time of 18 hours of AMG 300L hydrolyzate which gave an 98% of its chemical components was glucose.
