Rice bran and cassava peel can be used as nutrients for yeast growth to produce mannoproteins. Currently, the application of yeast cell wall mannoproteins has only limited use in the food sector such as winemaking, stabilizers and emulsifiers in salad dressings. The functional and biological abilities of mannoproteins are influenced by their constituent components. Currently, has been found research that mannan and protein, which are components of mannoproteins, have potential as antioxidants. Based on a literature review, mannoproteins have potential as antioxidants because many hydroxyl groups are found in the chain of bonds. All mannan fractions have superior scavenging activity against hydroxyl groups at a concentration of 3.2 mg / mL while to produce scavenging activity against oxidative superoxide groups requires 3.3 mg / mL. Utilization of rice bran and cassava peels through the production of mannoproteins as antioxidants is an environmental friendly action because it can reduce the volume and utilize agro-industrial waste, so that environmental pollution can be better controlled.
