- Abstract
Peptides obtained from hydrolysis have many bioactive properties and have strong biological activities against free radicals and prevent antioxidant processes that cause damage to biological macromolecules and degradation and quality reduction. Due to the large amount of rice production in the world, a large number of rice bran is produced and available. As a suitable and cheap production source, rice bran can be used for the production of plant-derived peptides. Optimizing the conditions of enzymatic hydrolysis of rice by alcalase enzyme was done with the aim of achieving anti-allergenic properties. In order to investigate the antioxidant activities of peptides, iron 3 reduction power tests and DPPH free radical activities and total antioxidant activities were used. In order to optimize the time of the Expert design software and the response surface method with three different changes: this enzyme was applied to the substrate 1-3%, temperature 40-55 degrees Celsius and hydrolysis 30-210 minutes. In the set conditions of the treatment including temperature of 51.5 degrees Celsius, 131.5 minutes and enzyme substrate 3%, it was obtained that DPPH free radical is 37.172%, total antioxidant activity is 1.109% and reducing agent is 2.084%. The obtained results showed that the process of rice bran production by alcalase enzyme leads to the production of peptides with high antianxiety properties and it is noteworthy that they can be used in the production of super-beneficial foods and pharmaceutical industries and also replace them .
