Development and characterization of a carbon-based composite material for reducin gpatulin levels in apple juice.

Ultrafine activated carbon was bonded onto granular quartz to produce a composite carbon adsorbent (CCA) with a high carbonaceous surface area, good bed porosity and increased bulk density.  CCA in fixedbed adsorption columns was then evaluated for efficacy in reducing patulin levels from aqueous solitions and apple juice.  Results indicated that 50% breakthrough capacities for patulin on 1.0, 0.5 and 0.25 g CCA columns were 137.5, 38.5 and 19.9 mg, respectively.  The effectiveness of CCA to adsorb patulin and prevent toxic effect was confirmed in vitro using adult hydra in culture.  Fixed-bed adsorption with 1.0 g of CCA was also effective in reducing patulin concentrations in a naturally contaminated apple juice containing patulin at 20 mg/ L.
