Implication

Proteomic analyses uncover diverse proteins in caviar extracts, suggesting crucial implications for cosmetic safety and efficacy.

Key Points

  • This research aims to characterize the molecular composition of commercial caviar extracts through proteomic analysis.
  • Proteomic analyses were performed on 14 commercial caviar samples from various sturgeon species.
  • Samples were examined independently in two laboratories to confirm findings.
  • Identified proteins and peptides were compared across different geographical origins.
  • 1437 protein groups and 3452 unique peptides were identified across samples.
  • Consistent overlaps with ovarian fluid proteins were found, implying co-extraction during roe harvesting.
  • Proteins influencing skin biology were revealed, suggesting a need for updated safety assessments.
