The Folin-Ciocalteu assay is a widely used method for measuring the total phenolic content (TPC) in honey, but it can be affected by presence of reducing sugars which lead to interference and an over-estimation its TPC. To optimize honey analysis, effect pH on was investigated. A number scenarios were tested using different concentrations Na2CO3 (0.00%, 0.75%, 0.94%, 7.50%) order minimize sugar...
