The present work reports the development of a novel molecularly imprinted polymer (MIP) electrochemical sensor for limonene determination in orange industry wastewater. MIP sensor was constructed through the pyrrole electropolymerization in the presence of limonene on glassy carbon electrode surface (GCE/MIP). Electrode surface as characterized by electrochemical, spectroscopy and microscopic techniques. The analysis was performed using differential pulse voltammetry, employing hexacyanoferrate as the electrochemically active probe. Under optimized conditions, the proposed GCE/MIP sensor displayed linear range from 1.0 to 100 pmol L with a high sensitivity (0.92 nA L pmol) and low detection limit (0,87 pmol L), as well as excellent storage stability, repeatability and reproducibility. The imprinted factor found for the sensor was 4.1 with high selectivity. The applicability of the sensor was successfully evaluated by limonene determination in yellow water sample. GCE/MIP showed recovery from 97 to 105 %. The results, altogether, indicate that the GCE/MIP sensor can provide a sensitive and selective method for limonene determination with accuracy and precision.

The intricate relationship between the chemical composition and sensory attributes of various pineapple ( var. ) cultivars was investigated using multivariate statistical analysis. Our findings revealed that high hedonic ratings for pineapples are partially attributed to their distinct flavor profiles such as tropical fruit, sweetness, coconut, and floral aroma and flavor and textural qualities like juiciness and fibrousness.

Zanthoxylum schinifolium is used traditionally as herbal medicine, spice and flavouring agent, with its essential oil (ZEO）having potential anti-inflammatory and analgesic activity. In this study, the ZEO was extracted using supercritical CO2（Sup-CO2), and the extraction process optimized using Response Surface Methodology. The composition of the ZEO was analyzed using gas chromatography-mass spectrometry (GC-MS), while the role of the ZEO in inhibiting the release of inflammatory factors from LPS-stimulated RAW264.

Citrus flavors are globally popular in food industry, yet research on the perceptual preferences of various citrus flavors is limited. Based on the subjective sensory evaluation, this study introduces a novel sensory analysis approach, using electroencephalography (EEG), to objectively measure the sensory and cognitive responses to nine citrus flavors, including d-limonene, concentrated (H-) and original essential oils of sweet orange (SEO), bergamot EO (BEO), lemon EO (LEO), and grapefruit EO (GEO). Results revealed that δ (0.

Citri Reticulatae Pericarpium peel ('Chenpi' tea) is a popular food-medicine functional tea, which mainly existing unsteamed (CRP) and steamed (SCRP) products. In this study, a combination of electronic nose and GC-MS analysis showed that aged SCRP had a more intense aroma, which was attributed to the significant reduction or disappearance of components representing refreshing aroma, such as β-Myrcene and d-Limonene, while some components with thick odors like Valencene were newly formed. For the 'dryness'-like effect, the weaker effect of SCRP relative to CRP was initially confirmed in rats, as characterized by water intake, submandibular gland index, and hemorheology, consistenting with the expression trend of aquaporin (AQP) 2, 3 and 5 mRNA.
