Fixed-bed purification of ferulic acid from sugar-beet pulp using activated carbon: Optimization studies

Recovery, concentration and purification of phenolic compounds by adsorption: A review

“…The breakthrough curves offer information on the adsorption equilibrium and dynamics, and enable the successful design and operation of fixed-beds. ACs have been used as adsorbents in column studies performed with model phenol solutions (Aravindhan et al, 2009;Richard et al, 2010) and with real solutions (Camporro et al, 1994;Couteau and Mathaly, 1998;Rengaraj et al, 2002a;El-Shafey et al, 2005;Vázquez et al, 2007a). Column adsorption of model solutions has also been assayed using resins (Ferreira and Rodrigues, 1995;Abburi, 2003;Otero et al, 2005a, b;Zabkova et al, 2006;Pan et al, 2008;Liu et al, 2010a,b), synthetic polymers (Romo et al, 2008), low cost adsorbents (Banat and Al-Asheh, 2001a;Rengaraj et al, 2002b;Navia et al, 2006), naturally occurring biopolymers (Nadavala et al, 2009), and biomass (Kumar et al, 2009a,b).…”

“…Alternatively, oligosaccharides from natural products (Sanz et al, 2005) or generated by enzymatic reactions (Boon et al, 2000) can be selectively removed by ACs; this kind of processes does not involve the adsorption of phenolics and are not considered here. Fructooligosaccharides from beet pulp were purified with ACs, which retained ferulic acids with no significant binding of sugars and limited adsorption of oligosaccharides (Couteau and Mathaly, 1997;Couteau and Mathaly, 1998). Table 9 Representative examples on adsorption applications in the detoxification of hydrolyzates to be used as fermentation media.…”

Molecular tools for selective recovery and detection of lignin-derived molecules

“…On the other hand, the adsorption and desorption conditions in a matrix can be optimized to favor the recovery of certain molecules. For example, the selective recovery of a ferulic acid from enzymatically treated sugar-beet pulp was studied by Couteau & Mathaly (1998) by optimizing a fixed-bed system utilizing activated carbon. 47 In their study, 50% ferulic acid purity was achieved.…”

“…For example, the selective recovery of a ferulic acid from enzymatically treated sugar-beet pulp was studied by Couteau & Mathaly (1998) by optimizing a fixed-bed system utilizing activated carbon. 47 In their study, 50% ferulic acid purity was achieved. As another example, ferulic acid recovery studies conducted by Tilay et al (2008) revealed 50.89% purity and 57.97% recovery efficiency for polymeric adsorbents.…”

Identification and Characterization of Feruloyl Esterases Produced by Probiotic Bacteria

“…For example, the rat chow is formulated with many ingredients containing 6% to 8% (weight to weight) of fiber in the form of sugar beet pulp. The sugar beet pulp is an important source of ferulic acid, a phytophenol with antioxidative and anti-inflammatory effects (Couteau et al, 1998). It has been demonstrated that low dosage of cinnamic acids (especially ferulic acid) has been related with the stimulation of insulin secretion (Balasubashini et al, 2003, Adisakwattana et al, 2008, prevention of oxidative stress and lipid peroxidation (Balasubashini et al, 2004, Srinivasan et al, 2007, and inhibition of diabetic nephropathy progression (Fujita et al, 2008).…”
