BACKGROUND: Sweet corn cob (SCC), an agricultural by-product of the corn-processing industry, contains more than 80% insoluble bound ferulic acid (FA). Extraction of these bound phenolics can be achieved through chemical or enzymatic hydrolysis; however, the shift towards greener chemistry has raised awareness about the use of enzymatic hydrolysis. In the present study, the ability of ferulic acid esterase (FAE) and xylanase (XY) to catalyze the hydrolysis of FA from SCC was investigated. Response surface methodology (RSM), based on a five-level, four-factor central composite rotatable design (CCRD), was used to establish the optimum conditions for enzymatic hydrolysis of FA from SCC. Sweet corn cob was treated with a combination of FAE and XY at various concentrations (FAE: 0.00 to 0.04 U/g; XY: 0.00 to 18 093.5 U/g), temperatures (45 to 65 ∘ C), and pH levels (pH 4.5 to 6.5). RESULTS: The optimum extraction conditions predicted by the model were: FAE concentration of 0.02 U/g, XY concentration of 3475.3 U/g, extraction pH of 4.5, and an extraction temperature of 45 ∘ C.CONCLUSION: Under these conditions, the experimental yield of FA was 1.69 ± 0.02 g kg −1 of SCC, which is in agreement with the value predicted by the model.

“…Another study by Zheng et al showed a released of 34 g/L FA also by alkaline hydrolysis. Similarly, Salleh et al did an alkaline extraction to produce FA from paddy straw, and they obtained about 8.17 mg/g FA. Although these studies achieved higher FA yield, alkali treatments generate high base concentration and could led to undesirable changes in the treated lignocellulosic material .…”

Abandoning banana stem waste (BSW) seems a loss since it is a good source of lignocelluloses to produce ferulic acid (FA). This study was conducted to optimize the production of FA via feruloyl polysaccharide hydrolysis from BSW by fermentation with a soil mixed culture. The optimization used response surface methodology (RSM) based on a five level‐two factor central composite design (CCD). Parameters studied were the ratio of water to BSW (v/v) and incubation time (hours). Range values for each factor were 0.5:1 to 1.5:1 ratio and 12–36 h, respectively. Interaction between these factors revealed that effect of time was greater than ratio of water to BSW, since a sufficient time is important for the mixed culture to fully use BSW during inoculation. The optimum condition was determined as 1:1 water to BSW ratio and 27 h incubation time. Under this optimized condition, the maximum FA produced was 1.17 mg FA/g BSW, which was in close agreement with predicted values (30%). This indicates that the suitability of the models was successfully developed by RSM‐CCD in optimizing the hydrolysis conditions for maximum FA production. That being said, BSW is proven useful and highly feasible for producing quality goods naturally. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1217–1223, 2017

“…Such relatively higher content of alkali-labile crosslinkages within the lignin network or between lignin and polysaccharides might explain the fast and easy solubilisation of both phenolic acids by alkaline treatments [20]. Consequently, it will be necessary to cleave the esterhemicellulose bridge with enzymes or alkalis in order to release ferulic acid [14].…”

Extraction of ferulic acid from sugar beet pulp by alkaline hydrolysis and organic solvent methods

Extraction of ferulic acid from sugar beet pulp was carried out using three extraction solvents, sodium hydroxide (0.5, 1, 2 M), methanol and their mixture (alkaline methanolic solvent). The Ferulic acid extracted by each solvent was identified and quantified by HPLC method and the effects of solvent type, concentration and reaction time on ferulic acid solubilisation were assessed. There were differences in the contents of products extracted in the experiment conditions. The minimum amount of ferulic acid was obtained from methanolic extract while the highest concentrations (957.4 mg/L ferulic acid) were obtained employing the highest NaOH concentration (2 M), and reaction time (12 h), so phenolic compounds are better released with alkaline hydrolysis than in methanol conditions. Finally a simple procedure for the purification of ferulic acid from the alkaline extracts is presented and evaluated by FT-IR spectrum.
