Most of the soft white sugar products are beets and sugar cane. Sugar factories use beets and sugar cane as raw materials and are produced by carbonic acid or sulfurous acid processes. They are mainly used for civilian purposes and are indispensable foods in people's daily lives. The consumption hotspots of soft sugar are far away from sugar beet and sugar cane planting bases, so sugar beet and sugar cane cannot be used as raw materials to produce soft sugar. This standard is implemented to adapt to and meet the needs of consumers and solve the problem of enterprises using rock sugar mother liquor and sucrose syrup as direct or indirect raw materials to produce soft white sugar that is reasonable and meets scientific and sugar safety standards.
