EMIDIO, João Expedito et al. Enzymatic hydrolysis in sugarcane syrup artisanal processing. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.4, pp.231-240. ISSN 0871-018X.  https://doi.org/10.19084/rca.18776.

The aim of the study was to evaluate the process of sucrose hydrolysis by the action of enzymes present in baker’s yeast (Saccharomyces cerevisiae)in a solution of VHP sugar and sugarcane juice. The production and characterization of sugarcane syrups with partial sucrose inversion by the addition of baker’s yeasts on the selected conditions was also evaluated. It was verified that the sucrose from sugarcane juice was partially hydrolyzed by the action of enzymes present in the baker’s yeast, and that the syrups produced in this way meet the specifications, being even preferred among consumers. The results obtained indicated a viable and low-cost solution to produce sugarcane syrups with reducing sugar content around 30% (by the addition of 0.010% of instant dry yeast), thus guaranteeing a better stability in relation to sucrose crystallization.
