Summary: Ultrasound-assisted solvent extraction (UAE) was used to extract Madhuca longifolia seed oil. The effect of extraction conditions on oil yield and recovery was investigated. UAE showed comparable oil yield and recovery to Soxhlet extraction (SXE), while mechanical pressing (ME) had lower recovery. UAE did not affect the composition of fatty acids and triacylglycerol profile. Interestingly, UAE-extracted oil had significantly higher antioxidant capacity compared to SXE or ME.

Summary: The study optimized the ultrasound-assisted extraction of oil from lesser mealworm larvae powders using ethanol/isopropanol as the superior solvent, achieving the highest extraction efficiency and in vitro antioxidant activity at a solvent-to-LMLPs ratio of 22.5 v/w and 70°C. The oil diffusivity in ethanol-isopropanol during the extraction process was significantly better than that of n-hexane, resulting in improved efficiency. Additionally, the improved antioxidant activity was associated with higher total phenolic and carotenoid contents in the extracted oil, suggesting enhanced oxidative stability.

Summary: Vegetable oils are extracted from oilseeds, fruits, and other parts of plants. The method of oil extraction greatly affects the quality of the final product and the environment. Mechanical pressing and solvent extraction are commonly used methods, but they have disadvantages in terms of product quality and environmental impact. This review explores the use of microwave and ultrasound-assisted extraction in conventional oil extraction processes and discusses their effects on the physicochemical properties and antioxidant properties of the extracted oil.

Summary: The study compared protein properties extracted by SDEE and pH-shift from tuna meat and liver, finding that SDEE had similar effects on proteins but superior ability in maintaining protein structure, digestion, gelation, and emulsification properties. The results suggest that SDEE-produced protein has outstanding potential in industrial applications due to its ability to remove impurities and improve protein functionality.

Summary: This study explored the impact of pressure (10, 20, 30, 40 MPa) on the supercritical solvent impregnation (SSI) of pomegranate peel extract (PPE) into low-density polyethylene (LDPE) film, aiming to develop a potential antioxidant and antimicrobial active food packaging material. The antimicrobial activities of both PPE and impregnated films were assessed. Impregnating PPE into LDPE film enhanced UV light barrier and antioxidant properties. The highest impregnation efficiency was achieved at pressures of 30 and 40 MPa. The release of PPE from the LDPE matrix into its surrounding medium was confirmed, indicating the retained antioxidant activities of PPE after SSI. These findings demonstrate the feasibility of using SSI as a green method to produce LDPE/PPE films for active food packaging.

Summary: In this study, four polythiourethane films with different types of polyols and isocyanates were synthesized, characterized, and foamed. The results showed that the type of isocyanate greatly influenced the crystallinity and stiffness of the polymers, while the type of polyol modified the FT-IR spectra and the decomposition curve of the material with temperature. Furthermore, the choice of isocyanate also affected the properties of the foams obtained from the polymeric material.

Summary: This study experimentally assessed the hydrodynamic characteristics of supercritical-pressure R134a in a horizontal circular tube. It was found that the hydrodynamic characteristic curve of R134a under supercritical pressure does not have a negative-slope region but a transition region. The transition region becomes more evident with increasing heat flux, while it weakens with increasing pressure and inlet temperature. Moreover, the onset of the transition region shifts in the direction of high mass flow rate with increasing heat flux.

Summary: This research aimed to valorize brewery spent grain (BSG) using subcritical water hydrolysis (SWH) modified by six different natural deep eutectic solvents (DES) and determining their bipotentialities. The findings showed that BSG hydrolysates obtained through DES-induced SWH contained high levels of sugars, proteins, flavonoids, phenolic compounds, and essential amino acids. The hydrolysates also demonstrated antimicrobial activities, and the presence of bioactive compounds was confirmed through FT-IR analysis. This comprehensive profiling of bioactive compounds from BSG using DES-mediated SWH can contribute to the efficient valorization of BSG for industrial purposes.
