Summary: This study analyzed the impact of growing location on the yield and composition of kaffir lime leaves essential oils. The results showed that essential oil yield was positively correlated with rainfall, soil organic carbon, soil pH, nitrogen, phosphorus, and magnesium levels. Additionally, the major component citronellal was significantly affected by the growing location and correlated with soil pH and leaf mineral content.

Summary: This study investigated the anti-proliferative activity and immunomodulation potential of crude kaffir lime leaf extract constituents in co-culture. Results demonstrated high cytotoxicity to the SCC15 cell line but not to macrophages, as well as suppression of cell migration and colony formation. Treatment induced cell cycle arrest and apoptosis, mediated by Bcl-2 inhibition and Bax activation. Co-culture with activated macrophages and kaffir lime extract enhanced pro-inflammatory macrophage development and TNF-alpha production, leading to SCC15 apoptosis. The findings suggest novel potential activities of kaffir lime leaf extracts in inducing M1 polarization and direct anti-proliferative effects against SCC15.

Summary: The study evaluated the storage stability of powdered coriander, parsley, and celery leaves dried using different methods based on their moisture sorption isotherms and glass transition temperatures. Various models accurately described the relationship between water activity and equilibrium moisture content of the dried materials, while different models predicted the variations in T-g vs. a(w) or EMC. The dried powdered leaves showed the highest stability at specific equilibrium moisture content ranges and storage temperatures.

Summary: This study investigated the impact of external conditions on the drying kinetics of a thin layer of corn during convective drying. The density and specific volume of corn grain were measured, and desorption isotherms were determined for different temperatures and water activities. A comparison was made between convective drying of a packed bed and a thin layer under the same conditions. The results showed that the GAB model was the most suitable to represent the desorption equilibrium moisture content of corn kernels in the suggested ranges of temperature and water activity, indicating that the desorption process is controlled by the enthalpy mechanism according to the entropy-enthalpy compensation theory.

Summary: Understanding sorption isotherms is important for optimizing drying processes and enhancing food shelf-life. This study investigated sweet cherry powder isotherms and found the Smith model to be the most reliable predictor. The net isosteric heat and differential entropy values of the cherry powder increased exponentially with decreasing moisture content.

Summary: This study successfully tested the adsorption behavior of Pb(II) ions from aqueous solution using magnetic activated carbon prepared from Citrus hystrix leaves (MCHLAC). The optimum contact time was found to be 90 min, and the optimum pH range was 5.0-7.0. The functionality, surface morphology and elemental composition of MCHLAC were explored through FTIR, SEM and EDX analysis. The equilibrium data fit well with the Langmuir model, indicating monolayer coverage of Pb(II) ions onto MCHLAC with a maximum adsorption capacity of 345.65 mg/g. Kinetic data followed a pseudo-second order model with film diffusion process. The thermodynamic studies showed that the uptake of Pb(II) ions is spontaneous and exothermic. A single-stage batch adsorber using the Langmuir adsorption isotherm equation was designed. The regeneration study demonstrated that MCHLAC could effectively remove Pb(II) ions for seven cycles of operation.
