Saccharomyces cerevisiae as a delivery system of Zataria multiflora Boiss. essential oil as a natural preservative for food applications: Encapsulation of Iranian Zataria multiflora Boiss. essential oil. | LitMetric

AI Article Synopsis

  • - The study evaluates how well Iranian Zateria multiflora boiss essential oil (ZEO) is encapsulated in Saccharomyces cerevisiae yeast cells by testing various oil/yeast ratios and temperatures.
  • - The results showed that carvacrol and thymol, two key components of ZEO, had encapsulation efficiencies of approximately 30.9% and 44.5%, respectively, and the yeast cells maintained stability over four weeks.
  • - The essential oil can be efficiently released, with around 60% released within the first hour, making it a promising natural preservative for the food and drug industries.

Article Abstract

Background: The following study is an evaluation of the encapsulation, stability and release profile of Iranian Zateria multiflora boiss essential oil (ZEO) in Saccharomyces cerevisiae yeast cells. Encapsulation was performed with different essential oil / yeast weight ratios at different temperatures. The encapsulation efficiency and stability of the loaded yeasts and the release profiles of carvacrol and thymol (as the main active ingredients of ZEO) were also investigated.

Result: The encapsulation efficiencies of carvacrol and thymol at a ZEO / yeast weight ratio of 1.25 were 30.9% ± 0.01% and 44.5% ± 0.02%, respectively. Loaded yeast cells were stable during the 4-week storage period. Both carvacrol and thymol showed substantial releases of around 60% during the first hour and around 70% during the second hour at two different water temperatures, followed by steady release.

Conclusion: Zateria multiflora boiss essential oil can be encapsulated effectively in S. cerevisiae yeast cells, refrigerated without degradation, and released efficiently. Zateria multiflora boiss essential oil encapsulated into S. cerevisiae yeast may be used as a potential preservative for the food and drug industry. © 2020 Society of Chemical Industry.
