Abstract:According to the market survey， it was serious that brown sugar was imitated by refined brown sugar in China. In the market， about 89.9 % so-called brown sugar was actually refined brown sugar. It was the reason that the diversities of physical and chemical properties between brown sugar and refined brown sugar were not systematically investigated in current domestic researches why the imitations spread unchecked. In this paper， manufacture craft， nutritional properties， and health effects of these two kinds of sugar were compared and ana－ lyzed， and the future research work was expected on the basis of the researches at abroad.
