Physico-chemical properties of solid and molten Jaggery from CoLk94184

Abstract

Jaggery is the sugarcane based traditional Indian sweetener. Jaggery is nutritious and easily available to the rural people. The Physico-chemical properties of Jaggery is the one of the most important key parameters. Jaggery (Variety: CoLk 94184) was used in the entire experimental tests. In the present study, five samples were collected and evaluated of Physico-chemical characteristics of fresh jaggery (molten and solid). The investigation were carried out for determination of Physico-chemical evaluation such as total soluble solids, colour, true density, moisture content, pH, reducing sugar, hardness and viscosity according to standard procedures. The mean value of density, moisture content, reducing sugar and texture of solid jaggery were measured to be 1.36 g/cc, 6.97% (db), 6.86% and 346 N respectively. The mean value of total soluble solids (⁰brix), colour (L*, a* and b* values), moisture content, pH and viscosity of molten jaggery were measured to be 79.80⁰, 35.52 (L*), 7.34 (a*),-5.02 (b*), 25.57% (db), 5.87 and 2519.79 mPa.s., respectively.
