Sour powder candy is a kind of white powdery sugar. Sugar powder particles are very fine, and there is about 3~10% starch mixture (generally corn flour), which can be used as condiment or to make various folk delicacies. It has the function of moistureproof and preventing sugar particles from knotting.
There are two main production methods. One is the spray drying method, that is, white granulated sugar is made into a high concentration aqueous solution through vacuum spray and drying. It has the characteristics of uniform powder and good water solubility, but its production cost is high, which requires high equipment and process requirements. Only a few developed countries in Europe and America have a certain amount of production. Another way is to directly crush white granulated sugar or crystal sugar with a grinder.
There are many ways to pack the sour powder such as put in small tube called cc stick candy , or put in many kinds of bags , and many shapes of bottles.
