Chlorella is a kind of freshwater unicellular algae, which widely lives in some fresh water sources, such as lakes. However, due to the imperfect production technology, Chlorella has not been widely studied and produced in mainland China. In 1960s, Taiwan Province Province and Japan began to conduct large-scale research, development and production, and Taiwan Province Province has a superior algae growth environment. Therefore, the market share of Chlorella products in Taiwan Province Province has always been the first in the world, and the first one is the green algae chips produced by Taiwan Province Green Algae Industry Co., Ltd.
