Honey is a natural sweetener and highly nutritious traditional medicine. Composition of honey vary according to several factors such as geographical origin, climacteric condition, type of flora, packaging and storage condition. The objective of this study was aimed to determine the physico-chemical properties of 11 honey samples of different flora collected from local market. Honey samples were analyzed for pH, total soluble solids (TSS), acidity, specific gravity, moisture, protein, fat, fiber, total sugar, sucrose, phenols, electrical conductivity, major and minor 25 elements (Na, K, Ca, Fe, Mg, Mn, Cu, Ag, Al, As, Ba, Bi, Cs, Ga, In, Pb, Rb, Se, Sr, Ti, U, V, Cr and Hg). The protein and fat content of the honey samples varies between 0.09 to 0.32g per 100g and 0.11to 0.69g per 100g respectively. The highest amount of protein content was in Jamun and Carom seed (0.32%) and fat content in multi-floral (0.69%). The elemental data reported that the range of Na was between 211 ppm to 475 ppm and the K was between 250 ppm to 1936 ppm. The Litchi sample was having highest Na content of 475 ppm and Jamun sample was having highest amount of 1936 ppm of K. Among all honey samples, Karvi, Sunflower, Multifloral, Eucalyptus, Hirda-gela and Jamun showed good nutritional value with respect to protein, fat and mineral content whereas multi-flora was having highest organoleptic score. The results concluded that physical and chemical parameters of the 11 honey samples vary according to their type of flora and region. |
