d-limonene

This study explores the relationships of evaporation dynamics, metal oxide semiconductor (MOS) sensor analysis, sensory panel perception of essential oils, and molecular docking interactions of D-limonene, eugenol, citronellol, isoamyl acetate, and cis-3-hexen-1-ol. The VOCs showed strong correlations (Pearson r=0.96–0.98) between evaporation rate and odor intensity for D-limonene, isoamyl acetate, and cis-3-hexen-1-ol, whereas eugenol exhibited low correlations. Real-time MOS data validated these evaporation profiles.

In this study, D-limonene is integrated into films made with different ratios of gelatin to β-CD. The FTIR, vacuum liquid absorption method and gravimetric analysis were used to assess porosity and swelling behavior. Inclusion and retention were detected by FTIR analysis in distinctive peaks at 870–890 cm-1. Films with a 3:1 gelatin to β-CD ratio had a higher D-limonene payload. Porosity and swelling are enhanced with increasing β-CD content.

This study explores the effectiveness of β-cyclodextrin (β-CD) as a carrier for essential oils (EOs), specifically d-limonene, and eugenol, within biodegradable delivery systems. Inclusion complexes were prepared via coprecipitation and analyzed using Fourier-transform infrared spectroscopy. FTIR analysis confirmed the encapsulation, indicated by the shift in the O-H stretching vibrations of β-CD and a reduction in the intensity of the C-H stretching vibrations of d-limonene, which suggests successful molecular inclusion.
