Description:
Background: Phenolic compounds are one of the main groups of secondary metabolites
responsible for multiple biological and pharmacological properties that play a vital role in
improving human health quality. Encapsulation by spray dryer creates protection toward the
phenolic compounds as an efficient way for increasing product performance.
Methods: The phenolic compounds of Satureja khuzistanica Jamzad (SKH) and S. rechingeri
Jamzad (SRH) were enriched based on adsorbent resin column chromatography and the
enrichment index was confirmed by HPLC-UV analysis. Gum Arabic, carboxylated chitosan,
and pectin with the optimum percentage of 1% w/w used to encapsulate SKH and SRH by the
spray drying technique.
Results: Encapsulation yield was 38.18 – 59.00 %, particle size ranged 2.278 - 4.689 µm, and
release time was between 4.08 - 82.08 min. The gum Arabic-based capsules showed the fastest
and pectin-based revealed the slowest release time. The best kinetic model explained a release
mechanism was Korsmeyer model. Anomalous transport was observed from all formulas except
SKH-gum Arabic (case-I transport), SKH-pectin, and SRH-carboxylated-chitosan (super caseII transport). The cytotoxic activity of encapsulate SKH’s revealed reducing the viability of AGS
evaluated by the MTT compared with SRH’s.
Conclusion: Encapsulation by spray drying has proven to be a promising technique to improve
the bioavailability, release time, and mechanism of functional polyphenolic compounds as
medicines, food supplements, and food additives.
