ICUMSA 100 is a measure of the color and purity of sugar, as defined by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA). It is a relatively low level of coloration for refined sugar.
Sugar with an ICUMSA value of 100 is considered to be very light in color. It is often used in applications where a high level of purity and a minimal color impact on the final product are desired. This can include industries such as pharmaceuticals, certain types of beverages, and specialized food products.
Remember that the ICUMSA scale is just one of several ways to measure the quality of sugar. Other factors, such as granulation and moisture content, also play a role in determining the suitability of sugar for various applications. It's always important to verify the specific requirements of any industry or application before selecting a particular grade of sugar.
