Application of bird’s nest extract to anti-aging serum.

Abstract

This study assessed the antioxidant capacity of bird’s nest extract, the serum that was added bird’s nest extract and determined the appropriate ratio of bird’s nest extract in the anti-aging serum. 1% bird’s nest extract hydrolyzed by bromelain showed the ability to reduce DPPH (SC) radical scavenging and total oxidant activities were 82.5±2.5% and 5.24±0.5 mg AA/ml extract, respectively. The antioxidant in anti-aging serum was proportional to the additional bird’s nest extract concentration and the bird’s nest extract content did not significantly affect the pH of this serum. The tested concentrations of bird’s nest extract supplemented to the anti-aging serum were 5, 10, 15, and 20%, the product was then evaluated sensory, assessed the change of pH, microbiological criteria and storage temperature. The results showed that the optimum concentration of bird’s nest extract added to anti-aging serum was 10% and the product was stable when stored at 25±2 and 40±2°C after 3 months of research. Therefore, the selected concentration of bird’s nest extract was 10% for further studies to develop anti-aging serum product.
