Although sweet sorghum is a promising feedstock for bioenergy and biobased products, sweet sorghum-based biorefineries in the U.S. are still in the planning or pilot-scale stages. Accurate, rapid, and inexpensive metrology is known to streamline (bio)refining operations and drive the return on investment. In this study, new cyclic voltammetry (CV)-based methods were developed to rapidly classify sweet sorghum fermentable sugar feedstocks for electroactive functionalities. In addition to providing industrial QA/QC protocols, developed methods could be used to screen for the pest-resistant cultivars containing redox-active antifeedants (e.g., flavonoids, alkaloids, and aconitic acid), enabling germplasm development for a sustainable feedstock supply chain. Developed CV methods were tested on five male (Atlas, Chinese, Dale, Isidomba, and N98) and three female (N109B, N110B, and N111B) inbred lines and their hybrids (23 cultivars total) planted in April, May, and June of 2015 in Georgia, and harvested at the hard-dough stage. The peak anodic potential (E pa in volts) of derivative CV (pH 5, 0.1 M KCl) overlapped with quercetin and tannic acid model reductants. Fluorescent porphyrin/chlorophyll-like condensed and recalcitrant aromatic structure is likely to be the primary electron-enriched (highest CV peak areas) secondary product, and showed significant (p < 0.05) cultivar and planting date dependencies.

“…But far from the issue of an optimized and targeted fermentation, purification processes applied on by-products have to face specific challenges due to composition fluctuations and low purity of the target solute to valorize. Some studies exist on aconitic acid extraction by anion-exchange from cane molasses or juices [2,26,27] , but the data obtained (capacity information, etc) do not allow scaling up, neither performances prediction for different compositions. A report [28] on 2007 sugarcane campaign in La Réunion confirmed that there was about 5% of aconitic acid (% Dry Matter, w/w) in local sugarcane distilleries stillage, a waste representing a potential resource of more than 1200 t of aconitic acid /year, and up to now most often discharged in the sea.…”

Sugarcane stillage is rich in tri-carboxylic aconitic acid. To study its purification through anionexchange, selectivity coefficients between aconitate and the major competing minerals were determined on a weak-base resin for different pH. Simulation of solutes separation in column, using mass conservation equations and equilibrium theory, confirmed that resin in sulfate form and pH = 4.5 led to the best separation performances, and showed that a preliminary chloride removal up to 0.5 g L -1 was the most profitable to increase the ionic exchange capacity for aconitic acid. Demineralization of a real stillage by conventional electrodialysis followed by the optimized ion-exchange step, led to an aconitic acid-rich extract.

“…In particular, the extraction by precipitation has been studied by many, but it suffers from low yield and requires an added acidification/isolation step to convert the salt to the free acid . Although the isolation of aconitic acid via ion‐exchange resin has been studied thoroughly, the lifespan of the resin and the regeneration cost needs to be studied in detail before extraction of aconitic acid can be considered as a commercially viable option.…”

BACKGROUND Aconitic acid (propene‐1, 2, 3‐ tricarboxylic acid) is the most prevalent organic acid found in sugar cane. It is used in the food processing industry as an acidulant and can be used in the synthesis of plasticizers. It can also be used to synthesize biodegradable polyesters for tissue engineering applications. In this study, aconitic acid was isolated from sugarcane molasses via liquid–liquid extraction with ethyl acetate. Six combinations of time and temperature (1–6 h at either 30 or 40°C) were tested. In order to conserve solvent, ethyl acetate was recovered and reused for subsequent extractions. The recovery of aconitic acid from vinasse was also evaluated. RESULTS Under the most efficient set of conditions, 69% of the aconitic acid was recovered as free acid. The purity (HPLC) of the extracted acid was found to be 99.9%. Ethanol was an additional stream that was generated by fermentation of molasses and yields of 12.4% (g per 100 g of molasses) were obtained. CONCLUSION The yield of aconitic acid from molasses varied from 34–69%, depending on the extraction conditions, with purity of the extracted acid being 99.9%. The aconitic acid is of a quality sufficient to synthesize polymers that could realize high‐value in biomedical applications. © 2013 Society of Chemical Industry
