However, the need of a fluorometer, which may be not routinely available, is taken into account as a disadvantage of this methodology. The long evaluation time has also been a major criticism even if this assay can be automated. The CUPRAC assay has many similarities to FRAP, Cu is used instead of Fe. This assay is predicated on the discount of Cu to Cu by the antioxidants present in the sample. Cu forms a fancy with neocuproine (2,9-dimethyl-1,10-phenanthroline) with a most absorbance at 450 nm. A dilution curve generated by uric acid commonplace is used to transform sample absorbance to uric acid equivalents .
Therefore, pretreatment is a prerequisite unit operation to improve cellulose digestibility and conversion efficacy of the biomass. The data below are from 1960 to 2018, referring to the whole number of tons of food generated, recycled, composted, combusted with energy recovery and landfilled. The following diagram depicts the flow of wasted food from generator sectors to the management pathways.
