Abstract :
The levels of 10 oligosaccharides in 70 genuine Brazilian honeys of different floral types are reported. The contents of sucrose and isomaltose were broad, ranging from mean values of 0.07–0.77 and 0.18–0.71%, respectively. The mean values for maltose were in the range 1.58 to 3.77%. The level of turanose (0.78–2.03%) was similar to that of nigerose (1.11–2.81%). Low amounts of melibiose (0.05–0.15%) and panose (0.03–0.08%) were found in Brazilian honeys. Maltotriose, melezitose and raffinose, were present with mean values of 0.24–1.03, 0.21–0.37 and 0.10–0.25%, respectively. Between Brazilian states, honeys from São Paulo had mean values for melibiose significantly (P<0.05) lower than those from the Minas Gerais and Rio de Janeiro. The mean values for maltose and nigerose found in the Mato Grosso do Sul and Goiás states were significantly higher than from the Mato Grosso state. Honey samples from the Paraná state showed a mean value for maltotriose significantly higher than that from the Rio Grande do Sul state. The contents of maltose, nigerose, turanose and maltotriose proved to be useful for the differentiation of honey samples from different geographical regions and also may be valuable for testing the authenticity of Brazilian honeys.
