Nostoc commune is an edible terrestrial blue-green alga in Taiwan. Nostoc commune ethanol extract (NEE) evaluations anti-oxidation ability and phytochemicals composition levels, next the Nostoc commune powder were extract of cured polysaccharide and quantitative total sugar in vitro. In cell model, we used NEE in 3T3-L1 preadipocytes cell proliferation and lipid accumulations model. Nostoc commune powder was development seaweed noodle and determine acceptability by sense evaluation. This can be used as a raw material for Nostoc commune health food, feed supplement or as a food at a concentration of 1~50 µg/mL. In 3T3-L1 preadipocytes cell model, result showed NEE could reduce cell proliferation and lipid accumulations after NEE treatment, and 50 μg/mL NEE was not inhibiting 3T3-L1 cell viability. Finally, it was determined that the sensory evaluation of the 2% Nostoc commune noodles in the 50-59 age group had higher acceptance than other age groups.

1. Nostoc commune ethanol extract (NEE) has been found to have antioxidant capacity, and phytochemicals containing algal polysaccharides and triterpenes are beneficial to the human body.
2.50 µg/mL Nostoc commune ethanol extract (NEE) can reduce the proliferative capacity of 3T3-L1 preadipocytes, as well as inhibit adipocyte proliferation and lipid accumulation.
3. To develop noodles with Nostoc commune powder, it was found that 2% Nostoc commune noodles have good consumer acceptance and can inhibit the accumulation of triglyceride hyperplasia capacity of fat cells.

In the embodiment of the present, the food is added as raw materials for health ingredients of cereal liquid, brewed cereal flour, noodles, bread, and biscuits; the health food is added as health ingredients of capsules, oral tablets, solutions, powder , or combinations raw material. the content of the alcohol extract of Nostoc commune in the health food, feed additive or food is 1 to 5 wt%.
