Physicochemical Properties of Indian Honey at Different Concentrations and Temperatures

DOI: 10.22161/ijeab/1.4.51

Abstract:
Investigations were made on the effect of temperature (20-70°C) on the physicochemical parameters like ultrasonic velocity, density, electrical conductivity and total soluble solids (TDS) of honey having various concentrations (100, 90, 80, 70 and 60 (w/w)%). Some other properties pH, refractive index, °Brix and moisture content were also measured at room temperature. Ultrasonic velocity, density, surface tension, bulk modulus and acoustic impedance were negatively influenced by temperature. However the other parameters increase with temperature. All the honey parameters except density were significantly varies with temperature and concentration at 5% level of significance. A good correlation was obtained between electrical conductivity and TDS.
