Aconitic Acid Recovery from Renewable Feedstock and Review of Chemical and Biological Applications

“…The Pearson Product Moment Correlation showed a statistically significant ( p = 0.03) correlation (0.80) between the aconitic acid in the juice and cane tops/leaves. According to Gil Zapata [ 27 ], the aconitic acid in the sugarcane leaves is approximately 3–6 times higher than in stalk juice, which is consistent with information reported by others [ 99 ]. Ripener had no impact on aconitic acid in stalk juice but did have an impact in tops/leaves, where those plants treated with ripener had less aconitic acid [ 27 ].…”

“…Among the cultivars, HoCP 96-540, HoCP 04-838, HoCP 09-804, and L 01-299; HoCP 04-838 had significantly more trans -aconitic acid in the sugarcane juice (0.17%) when compared to the other cultivars [ 101 , 102 ], while HoCP 09-804 had more cis -aconitic acid than the others [ 102 ]. When a commercial process was developed for the recovery of aconitic acid from sugarcane streams, others noted that the sugarcane varieties were not grown for their high aconitic acid content but could be cultivated if so desired, at the expense of sucrose [ 99 ]. Whether or not varietal differences were the source of variation, it was reported that molasses from sugarcane grown in Louisiana contains more aconitic acid than molasses from the tropical climate of Guadalupe [ 103 ].…”

“…Martin [ 104 ] also noted that tropical molasses contained lower amounts of aconitic acid when compared to Louisiana molasses. Furthermore, Haines Jr. and Joyner [ 99 ] attributed the higher aconitic acid content in Louisiana sugar cane molasses to the shorter growing season when compared to Florida-grown cane. Summer fallow had no significant impact on the aconitic acid concentration in sugarcane juice [ 102 ].…”

“…The recovery of aconitic acid from sugarcane and sweet sorghum juice, syrup, and molasses via precipitation has been patented [ 112 , 113 , 114 ], as well as a process using ion exchange [ 115 , 116 ]. The precipitation method from sugarcane molasses was once the only method by which dicalcium magnesium aconitate was produced for plasticizer use [ 99 ]. The process included dilution, addition of lime and calcium chloride, followed by centrifugation to recover the precipitate, which was washed, centrifuged, and dried.…”

The recovery of polymerization grade aconitic acid from sugarcane molasses

“…Industrially feasible isolation of aconitic acid via precipitation of the Ca 2+ /Mg 2+ salt was made commercial in Louisiana Raceland Raw Sugar Corp, but a lack of demand for the chemical led the industry to abandon the practice. The extraction of aconitic acid from molasses via liquid–liquid extraction and ion exchange has also been studied.…”
