Various practical strategies have been employed to mitigate the detrimental effects of water deficit stress on plants such as application of nano-stimulants. Nanosilicon plays a crucial role in alleviating the deleterious impacts of both abiotic and biotic stresses in plants by modulating various phyto-morphological and physiological processes. This study aimed to examine the combined effects of drought stress and nanosilicon application on the morphological traits and essential oil content and compositions of hemp (Cannabis sativa L.

Identification of non-volatile compounds during the pile fermentation process of Liupao tea using widely targeted metabolomics based on UPLC-QTOF-MS.

J Food Sci Technol

February 2025

School of Food and Pharmaceutical Engineering (Liupao Tea modern Industry College), Wuzhou University, Wuzhou, 543002 China.

Unlabelled: Pile fermentation plays a crucial role in the formation of the unique flavor of Liupao tea, which can effectively reduce the bitterness of the tea and promote the formation of red tea soup. In this study, the non-volatiles changes of Liupao tea during pile fermentation processing were fully analyzed by UPLC-QTOF-MS/MS. A total of 271 metabolites with significant differences were identified in Liupao tea during pile fermentation( < 0.

Oven roasting effects on the physicochemical and chemosensory characteristics of hemp seeds ( L.).

J Food Sci Technol

February 2025

Department of GreenBio Science/Food Science and Technology, Gyeongsang National University, Jinju, 52725 Republic of Korea.

Physicochemical properties and flavor characteristics of hemp seeds (HS) were analyzed by roasting temperature (140 °C, 160 °C, 180 °C) and time (initial, 3, 6, 9, 12 min). HS with roasting showed a lightness () with increasing roasting time. Total flavonoid content (TFC) decreased significantly with roasting compared to initial, and total phenolic content (TPC) tended to decrease with increasing roasting time at low temperatures (140 °C), but relatively high temperatures (160 °C and 180 °C), TPC increased significantly with increasing roasting time.

Unlabelled: Solid phase extraction technique is a widely used sample preparation technique for the extraction of components from complex food matrices. However, there are several parameters in SPE that leads to low recovery, and reproducibility, insufficiently clean extracts and evaporation of volatile compounds. These drawbacks can be addressed through the use of innovative techniques and instrumentation that offers improved efficiency and accuracy for isolation of active constituents from food and beverage samples.
