Sangchao is known as namachocolate in Japan, and the word "sang" means "fresh" in Japanese characters, as well as unprocessed food. The word "raw" in Japanese means "fresh" and also means unprocessed food. Namachocolate is a new variety of chocolate based on Ganache chocolate from European countries. Compared to traditional chocolate, raw chocolate is moderately sweet, smooth and has a richer flavor. Since raw chocolate does not contain preservatives and other additives, it has a shorter shelf life of a few weeks to a month, and should be stored in an environment that maintains low temperatures to preserve freshness and flavor.
