The Extended Oxidative and Sensory Stability of Traditional Dairy-Based Oil with Steam-Distilled Essential Oils Extracted from the Bioactive-Rich Leaves of Ziziphora tenuior, Ferulago angulata, and Bunium persicum

Abstract

The oxidation rate and overall sensory acceptability of Iranian animal oil (IAO) during storage were evaluated after adding the bioactive essential oils extracted from medicinal herbs of Ziziphora tenuior, Ferulago angulata, and Bunium persicum. Results showed that the most dominant chemical constituents in Z. tenuior, F. angulata, and B. persicum essential oils were pulegone (12.77%), ferulagon (14.97%), and (+)-trans-carveol (57.70%), respectively. IAO contained more saturated fatty acids (67.43%, mainly palmitic and myristic acids) than unsaturated (32.27%, mostly oleic acid) ones. B. persicum essential oil compared to the other two oils significantly had more total flavonoid (1.08 mg quercetin equivalent/g), phenolic (123.2 mg GAE/g), carotenoid (591.31 mg/kg), and chlorophyll (24.32 mg/kg) contents. A significant dose-dependent increase in the overall sensory acceptability of IAO was found by increasing the concentration of B. persicum essential oil. Similar to tertiary butyl hydroquinone, the oil blend of IAO+10% B. persicum essential oil obtained the maximum overall sensory acceptability scores during 28 d cold storage due to the remarkable in vitro DPPH inhibition (83.45%) and ferric-reducing power (0.754 at Å700nm). A much slower formation rate in primary and secondary oxidation compounds in IAO rich in B. persicum essential oil during the storage was associated with the overall sensory acceptability data ( p < 0.01 , r = 0.951). Thus, this bioactive additive as a bio-preservative may well stabilize crude oils and emulsions.

“…Distillation procedures are also extensively used in the isolation of essential oils from their natural sources [71,72]. For this purpose, the plants or their specific part are incorporated over water into a distillation apparatus.…”

Incorporation of essential oils in Iranian traditional animal oil: an assessment of physicochemical and sensory assessment

“…Mohammadi reported that the main chemical constituents in Z. tenuior, F. angulata, and B. persicum essential oils were pulegone (12.77%), ferulagon (14.97%), and (+)-trans-carveol (57.70%), respectively. However, higher total phenolic content, total flavonoid content, total carotenoid, and total chlorophyll in B. persicum essential oil were found compared to Z. tenuior and F. angulata essential oils (Mohammadi et al, 2021).…”

“…The treatment containing 5% F. angulata had the highest TBA value, whereas treatments with B. persicum had the lowest increase in TBA value during storage (P < 0.05). This can be due to the increase in the latter's phenolic and limonene compounds that inhibited oxidation more effectively (Mohammadi et al, 2021). The high aromatic compound content of F. angulata, on the other hand, was not as effective in inhibiting the oxidation process.…”

“…The treatments containing B. persicum had the lowest PV. This can be due to the presence of active compounds such as limonene and Trans-Carveol and limonene derivatives (Mohammadi et al, 2021). PV of all treatments increased with longer storage time, depending on the type and the amount of applied essential oil.…”
