ICUMSA 150 sugar, also known as S-30 sugar, is a category of sugar that falls between raw and refined sugar. This classification, determined by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA), indicates a darker color than refined white sugar, but less pronounced than that of raw sugar. ICUMSA 150 results from the raw sugar refining process, where some of the impurities are removed, but some coloring and mineral substances are retained, giving the sugar a more amber hue. ICUMSA 150 sugar has a slightly grainier texture than white sugar and has a delicate flavor with hints of molasses, making it an interesting choice for certain culinary applications where a more complex flavor is desired. It is often used in the production of jams, sauces and baked goods to provide a subtle sweetness and nuance of color.
