Developing economical
methods to stabilize rice bran and extract RBO are important for the
small and medium size rice bran oil factory. An economical and
efficient method of stabilization is required for obtaining best
results. Stabilization of rice bran with domestic heating methods
could be a high potential method to pretreatment of rice bran for
mechanical pressing. However, there is not much information in the
literature about the application of different domestic heating
methods for stabilization of rice bran and its effect on extraction
yield, quality, phytochemical content and antioxidant activities of
cold-pressed RBO (Oryza saltiva L.) In this experiment, hot air
heating, roasting, steaming and microwaving were applied for
stabilization of rice bran for using in the cold pressing process.
Therefore, the aim of the present studywas to investigate the impact
of domestic heating on mechanical extraction yield, quality and
antioxidant properties of cold-pressed RBO.
