Avaliação dos parâmetros de aquecimento e níveis de hidroximetilfurfural de mel de abelhas Apis melífera africanizada (Lepeletier, 1836) com base na Portaria nº 6 DE 25 de julho de 1985

Abstract

Hydroxymethylfurfural – HMF is one of the parameters used to determine honey quality. Its high concentration can mainly indicate prolonged storage time and submission to high temperatures, HMF can still indicate if there has been adulteration in honey with the addition of reducing sugars. Its determination was made by the spectrophotometric method of (WHITE,1979). Current legislation (BRAZIL, 2000) dictates that the maximum permitted amount of HMF for Apis mellifera africanizada (Lepeletier, 1836) honey is 60 mg/g. For the determination of the HMF the samples were subjected to the heat treatment following the time x temperature binomials disposed in chapter II, of the decree nº6 of July 25, 1985 and verifying the veracity or this decree. The analytical method used was AOAC 980.23, also known as Whithe’s method, which made it possible to determine the concentration of HMF present in the samples. As a result it was possible to quantify the HMF present in the samples without and with heat treatment, and from statistical analysis verified if there was significant variation between the treatments. Therefore, it was concluded that the effects of temperature cause the increase of HMF concentration, as well as its exposure time and storage time.
