Conductivity ash determination
The specific conductivity of the sugar solution is measured at a known concentration to detect conductivity ash in white sugar. The ash amount is then determined using a factor. 28 gram / 100 gram concentration is used for white sugar.
The Turkish Food Codex Sugar Communiqué (Communiqué no: 2006 / 2006), issued by the Ministry of Agriculture and Rural Affairs in 40, enumerates the value of conductivity ash according to the ICUMSA method in the sugar solution, invert sugar it should be at most 0,1 by weight.
ICUMSA, the International Commission on Uniform Methods in Sugar Analysis, is a worldwide organization that brings together national sugar analysis committees in many countries. It is the only international organization interested in analytical methods in the sugar sector and has standardized a number of physical analyzes within the scope of food analysis.
Non-sugar substances analyzed in white sugar include ash and portions of ash. The higher the amount of ash, the higher the amount of water present on the surface of the sugar crystals. This water, which is deposited on the surface of sugar crystals, dissolves some sugar, creating an environment in which microorganisms can grow. In this way, sugar begins to deteriorate. Ash content is an important factor affecting sugar quality. In general, organic non-sugar substances also increase with kü.
Ash content also includes alkalis, acids and other non-sugar substances such as sodium and potassium. All of these have negative effects on sugar quality.
Analyzes for conductivity ash determination are carried out within the scope of physical analyzes in authorized laboratories. In these analyzes, standards published by domestic and foreign organizations are complied with. At the same time, generally accepted test methods and test criteria are followed and reliable and objective results are obtained.
