Use of Moringa oleífera Lamarck leaf extract as sugarcane juice clarifier: effects on clarifed juice and sugar

Moringa extracts used in sugarcane juice treatment and effects on ethanolic fermentation

“…The use of synthetic polyelectrolyte promoted higher flake sedimentation speed for both varieties. These results are similar to that of Costa et al (2014), who evaluated moringa leaf extract and synthetic polymer for cane juice clarification with pH 7.0 in sugar production, and found values of 0.5 and 3.5 cm/min, respectively.…”

“…These values were lower than those obtained by Thai et al (2012), who used synthetic polymer as flocculating agent in sugar production and observed sludge formation of about 200 ml. Nevertheless, when these adjuvants were not used in the juice of the variety RB867515, there was low impurities precipitation, which resulted in high sludge volume ( Figure 1B), as also observed by Costa et al (2014). Means followed by the same letter are not significantly different according to Tukey test at 0.05 of probability.…”

“…It should be noted that the coagulation/flocculation mechanism of moringa protein is similar to the polyelectrolyte, once positive charges are presents in molecule that adsorb particles of the medium (Borba, 2001). Costa et al (2014) observed that moringa leaf and seed extracts also had flocculation effects when used to treat sugarcane juice for sugar production. The objective of this study was to evaluate the flocculation effects of moringa leaf and seed extracts treatment on ethanol production during sugarcane juice fermentation.…”

Acrylamide replaced by moringa extract in sugar production

“…Analyzing the impurity sedimentation speed values on the order of 0.44 cm/min were observed for all treatments. These results are higher than those obtained by Costa et al (2014), who determined speeds up 0.27 cm/min when no polymer was used in the juice clarification process. Figure 1 shows the values obtained for the percentage of precipitated mud in the decanter and the turbidity removed from the juice.…”

Yeast CA-11 fermentation in musts treated with brown and green propolis

“…The treated juice was heated until ebullition to facilitate the reaction between calcium and phosphorus found in solution (Albuquerque, 2011). The heated juice was put in inox decanter containing 5 mg/L of Moringa oleifera Lamarck leaf extract (Costa et al, 2014); it was prepared according to Ghasi et al (2000), to facilitate impurity removal.…”
