Considerable efforts have been spent on environmentally friendly particles for the encapsulation of essential oils. Polymeric particles were developed to encapsulate the essential oil from Piper nigrum based on gelatin and poly–ε–caprolactone (PCL) carriers. Gas Chromatography ((Flame Ionization Detection (GC/FID) and Mass Spectrometry (GC/MS)), Atomic Force Microscopy (AFM), Nanoparticle Tracking Analysis (NTA), Confocal Laser Scanning Microscopy (CLSM), Attenuated Total Reflectance–Fourier-transform Infrared Spectroscopy (ATR–FTIR), and Ultraviolet–Visible (UV–VIS) spectroscopy were used for the full colloidal system characterization. The essential oil was mainly composed of β-caryophyllene (~35%). The stability of the encapsulated systems was evaluated by Encapsulation Efficiency (EE%), electrical conductivity, turbidity, pH, and organoleptic properties (color and odor) after adding different preservatives. The mixture of phenoxyethanol/isotialzoni-3-one (PNE system) resulted in enhanced stability of approximately 120 and 210 days under constant handling and shelf-life tests, respectively. The developed polymeric system presented a similar controlled release in acidic, neutral, or basic pH, and the release curves suggested a pulsatile release mechanism due to a complexation of essential oil in the PCL matrix. Our results showed that the developed system has potential as an alternative stable product and as a controlling agent, due to the pronounced bioactivity of the encapsulated essential oil.

Characterization of Four Piper Essential Oils (GC/MS and ATR-IR) Coupled to Chemometrics and Their anti-Helicobacter pylori Activity

Background: Essential oils represent a major class of natural products which are known for their antimicrobial activity. This study aimed to determine the composition of four Piper essential oils by gas chromatography mass spectrometry, attenuated total reflection infrared, and chemometric analysis. Results: Monoterpene was the most predominant class in Piper nigrum and white pepper (87.6 and 80%, respectively) with the dominance of α-pinene, β-pinene, 3-carene, limonene, and βcaryophyllene. Sesquiterpenes represented 50, 19.6, and 12.3% of the essential oils of Piper longum, white pepper, and P. nigrum, respectively. Unlike other species, Piper cubeba oil was found to be rich in aromatics (59%), with eugenol (10.7%) and methyl eugenol (47.4%) representing the major components along with β-myrcene (21.2%) and 1,8-cineole (6.4%). Only P. longum essential oil comprised about 18.2% of alkanes and 13.6% of alkenes. Application of chemometric analysis utilizing GC/MS and ATR-IR data displayed the same segregation pattern where both principal component analysis and hierarchal cluster analysis revealed that white pepper was most closely related to P. nigrum while being completely discriminated from other Piper species. The Piper oils showed promising inhibitory effects on Helicobacter pylori. P. longum oil recorded the most efficient anti-Helicobacter activity [minimum inhibitory concentration (MIC) value of 1.95 μg/ml, which is the same as the MIC of clarithromycin], followed by the oil of white pepper (MIC = 3.90 μg/ml), while P. cubeba and P. nigrum produced the lowest activity (MIC value of 7.81 μg/ ml). Conclusion: Piper essential oils can be used as nutritional supplements or therapeutic drugs to protect against H. pylori infection.

“…It is well-known that the metabolic composition of black pepper may be influenced by several factors including crop conditions, time of harvest (maturity), extraction method, storage, geographical origin, and spice processing, among others, with the remarkable influence of the region of origin . Moreover, the heat treatment applied during some spice processing (e.g., sterilization or drying processes) may lead to the inactivation of some compounds, and the increase of others by inhibiting some enzymes, as well as the formation of some chemicals …”

Black pepper is one of the most consumed spices all over the world. Due to its high demand and nutritional value, a metabolomics approach based on GC-Orbitrap-HRMS fingerprinting and chemometrics was applied to assess its geographical traceability and processing authenticity. GC-HRMS-based fingerprints were obtained using a simple ultrasound-assisted extraction method, which may be easily implemented in routine activities of quality control. Unsupervised methods, such as principal component analysis (PCA), were performed for sample overview according to the investigated origins (Brazil, Vietnam, and Sri Lanka) and processing (sterilized vs nonsterilized samples). Further orthogonal partial least squares discriminant analysis (OPLS-DA) models were validated by cross-and external validation, providing satisfactory performance for geographical and processing authentication, as well as excellent predictive ability for further samples. Furthermore, reliable putative identification of 12 key metabolites (markers) was performed, highlighting the feasibility of combining untargeted GC-HRMS analysis with chemometrics for quality control of black pepper.
