“…It could neither be completely desorbed by ethanol as that in granular activated charcoal according to Couteau and Mathaly (1997), nor by acetic ether. When addition of HCL to ethanol, desorption capacity slightly increased.…”

“…However, it is difficult to purify ferulic acid from the hydrolysate as it contains many components and is deeply browning. Using activated charcoal to adsorb ferulic acid could purify it from enzymatic solution (Couteau & Mathaly, 1997), but it's not a feasible way to purify ferulic acid in alkaline-hydrolysate, as activated charcoal strongly adsorbed the color substances produced during alkaline-hydrolysis and could be also washed out using alcohol or sodium hydroxide as the elute (not published). In our previous research, it was found that anion macroporous resin had high capacity for adsorbing ferulic acid in enzyme-hydrolysate from wheat bran and could be washed out by solutions of ethanol-acetic acid-water (Liu et al, 2004), suggesting that it's a choice to purify ferulic acid from alkaline-hydrolysate.…”

“…Concerning the family of cinnamic acid derivatives, AC has been used to isolate ferulic acid from an aqueous sugar-beet pulp enzyme hydrolyzate (Couteau and Mathaly, 1997) and from the cooking water of maize (Creppy, 2002). To the best of our knowledge, AC has not been used to isolate CGA from green coffee beans.…”

Chlorogenic acids, which are interesting natural antioxidants widespread in the plant kingdom, were extracted and purified from Mexican green coffee beans (Coffea arabica) using different methods. The final objective was to find an easy way to extract high-value molecules from a complex mixture, avoiding as much as possible the use of toxic solvents. Three extraction methods (hot water at 80 8C, aqueous methanol 70% (v/v), and aqueous isopropanol 60% (v/v)) were tested in combination with two isolating methods (activated carbon, different solvents). The extracted amounts of chlorogenic acids with the six treatments (4.67-5.87% dry basis) presented no significant differences. The one using hot water for extraction and of activated carbon for isolation, was the simplest and the most environmentally friendly. Thus it can be used as a previous step to obtain from green coffee a mixture rich in chlorogenic acids which can be further fractionated to purify a specific chlorogenic acid (i.e. in this work, 5-O-caffeoyl quinic acid using a silica gel column). Chlorogenic acids can be used as natural antioxidants in food or non-food products. To the best of our knowledge, activated carbon has not been used to isolate chlorogenic acids from green coffee.

“…For example, AC adsorption has been employed for processing industrial wastewater containing phenols, and for removing coloured substances from juices (Arslanoglu, Kar, & Arslan, 2005;Carabasa, Ibarz, Garza, & Barbosa-Cánovas, 1998) and vinegar (Achaerandio, Gü ell, Medina, Lamuela-Raventó s, & Ló pez, 2002). AC was successfully used for concentrating and purifiying ferulic acid from aqueous solutions (Couteau & Mathaly, 1997. Polymeric resins have also been used for the separation and purification of phenolic compounds from solutions of pure compounds (Scordino, Di Mauro, Passerini, & Maccarone, 2004) or from residues of vegetal processing (Aehle et al, 2004;Llorach, Tomás-Barberán, & Ferreres, 2004;Scordino, Di Mauro, Passerini, & Maccarone, 2003).…”
