Abstract:
This research was purposed to extract collagen-like proteins from ear mushroom (Auricularia auricula) and white jelly mushroom (Tremella fuciformis) as well as to study the extracted collagen property for application in cosmetics. The extraction was compared to methods of acetic acid extraction and three phase partitioning (TPP). The former method provided extraction yield of 0.33 ± 0.03 from the ear mushroom, while the white jelly mushroom could not be detected the extracted protein. The latter protocol exhibited the yield of 16.85 ± 0.41% and 16.85 ± 0.41% from ear and white jelly mushrooms, respectively. Amino acid analysis showed that the TPP-extracted collagen-like proteins contained 22.89% glycine and 17.88% proline which was similar to those of animal collagen. This extracted sample was more dissolved in 0.1 M NaOH than that in 0.5 M citric acid and DI water. However, the protein solution from citric acid dissolution contained higher protein amount of 18.26 ± 0.04 mg/g followed by those from NaOH and DI water exhibiting 16.13 ± 0.11 and 15.48 ± 0.13 mg/g, respectively. SDS-PAGE and HPLC analyses indicated that the collagen-like proteins from ear mushroom extracted by acetic acid possessed the property like the collagen from cow tendon than be extracted from the TPP method. The protein extracted from the white jelly mushroom showed no similarity to the collagen property.
