Summary: Analyzing essential oils is challenging due to their variable composition. This study evaluated the effectiveness of using enantioselective two-dimensional gas chromatography coupled with high-resolution time-of-flight mass spectrometry (GCxGC-HRTOF-MS) to classify different types of rose essential oils. The results showed that selecting ten specific compounds was sufficient for efficient classification. The study also compared the separation efficiencies of three stationary phases and found that Chirasil-Dex had the best separation factor and space.

Summary: For large dimensional spiked models, determining the order is crucial for dimension reduction. The authors propose a generic criterion based on location-shift truncated eigenvalues to estimate the order when the dimension is proportional to the sample size and the order diverges. Two versions of the criterion are suggested: the first uses a sequence of ridge ratios to separate the true order from other ratios, while the second utilizes double ridge ratios for better separation. An iterative procedure is employed to alleviate the bias in scale estimation. Numerical studies on spiked population models and Fisher matrices confirm the proposed methods' finite sample performances.

Summary: Breeding for intercropping is currently behind because most available varieties are selected for sole cropping systems. The study analyzed the performance of durum wheat and faba bean varieties in both pure and mixed cropping. Durum wheat performed well in both years, while faba bean was more affected by the growing season, indicating the need for breeding efforts to improve its performance in both pure and mixed cropping. A multivariate approach was proposed to evaluate the overall performance and relative importance of cereal and legume grains in intercropping.

Summary: In this study, a new tile-based supervised analysis method called tile-based RF analysis is introduced, which combines the four-grid tiling scheme for F-ratio analysis with Random Forest algorithm. The RF approach allows analysis of unbalanced data sets and provides more stringent feature selection. It is a promising method for identifying class-distinguishing analytes in complex biological matrices characterized by high between-class variance and high within-class variance.

Summary: In this study, a combination of solid-phase microextraction (SPME) Arrow method and comprehensive two-dimensional gas chromatography-mass spectrometry (GC x GC-MS) was developed to analyze the volatile composition of honey samples. The optimized sample preparation protocol ensured high extraction efficiency of the volatile organic compounds (VOCs) associated with the sensory properties and acceptance of honey. SPME Arrow showed higher sensitivity, precision, and capability to extract a larger number of compounds compared to conventional SPME. Overall, SPME Arrow and GC x GC-MS are highly suitable for elucidating the volatile composition of complex food samples, offering enhanced sensitivity and separation efficiency.

Summary: The study found that cocoa and its derived products may be contaminated by polycyclic aromatic hydrocarbons (PAHs), with higher levels of contamination in smoked samples. However, contamination levels decreased after roasting. Drying cocoa beans without smoke contact could reduce contamination, thereby reducing human exposure to potentially carcinogenic and genotoxic compounds.
