Consumer Advice
Sodium dehydroacetate is the water-soluble sodium salt of dehydroacetic acid, used as a preservative in bread, cakes, dried bean curd sticks and pickles. Under China's revised standard (GB 2760-2024) its permitted uses have been greatly narrowed and it is no longer allowed in baked goods. When buying pastries, mooncakes or similar baked items, try to choose products that do not list sodium dehydroacetate on the label.
