Role of Calcium Hydroxide in the Sugar Refining Industry

When you enjoy that spoonful of sugar in your tea or dessert, you might not think about the science behind its purity and taste. But hidden behind the sweet granules is a fascinating process — and one crucial player in this story is calcium hydroxide, commonly known as slaked lime powder or hydrated lime. While it might sound like something from a chemistry lab, Ca(OH)2 plays a vital and everyday role in ensuring the sugar we consume is safe, clean, and delicious. In this blog, we’ll explore how Ca(OH)2 contributes to the sugar refining industry and why its role is indispensable in turning raw sugarcane juice into pure, crystal-clear sugar. What Is Calcium Hydroxide? Calcium hydroxide (Ca(OH)₂), also known as slaked lime , is a white, odorless powder obtained by adding water to calcium oxide (quicklime). This process is called slaking, and it results in a soft, slightly alkaline compound with a wide range of industrial applications. In the sugar industry, Ca(OH)2 is primari...
