4. Conclusion
The relationship between effect of various treatments on sericin protein and its antioxidant activity was investigated. Results revealed that treatment with protease enzyme was found to affect antioxidant activity of CSE, suggesting that antioxidant activity could be enhanced by decreasing size of sericin protein. On the other hand, treatments with DTT, β-ME and UV light decreased antioxidant activity of CSE. Moreover, the antioxidant activity of the colorless supernatant protein fraction is higher than that of the yellow-precipitate fraction, suggesting that in addition to the yellow-pigment of flavonoids, colorless protein fraction possesses even stronger antioxidant activity.
However, stability of the extract should be needed in further study for practical use in food and cosmetic industries.
