Aiming at comparing the physicochemical quality of inspected honey with that of non-inspected honey from the informal market, both on sales in Rio de Janeiro State, Brazil, we have examined 35 samples of honey, among which 25 had been inspected and 10 were non-authorized.The following issues were investigated: fraud involving the addition of starch, of glucose (reducing sugar), of saccharose (non-reducing sugar) and of hydroxymethylfurfural (HMF), and determination of acidity and of protein.It so turned out that 100% of the non-inspected honey samples did not meet the parameters in at least one of our tests, the net result being expressed in the following terms: 70% of the samples contained starch; 30% had a protein content below the standard; 30% showed the red coloration for HMF and 30% for HMF showed the salmon coloration; 50% were below the floor for reducing sugars; 20% were above the ceiling for saccharose, and lastly 40% had an acidity level above the recommended.On the other hand, the results found in the samples of inspected honey were more satisfactory, the figures being as follows: 12% were positive for starch; 12% were positive for HMF, among which 4% showed the coloration typical for a concentration higher than 70mg/kg and 8% higher than 40mg/kg; 4% were below the standard for reducing sugars, and lastly 12% presented an acidity level above the legal recommendation.
