Summary: This study immobilized a commercial enzyme cocktail for fruit juice clarification on chitosan beads and found that despite low activity recovery after immobilization, the stability of the immobilized enzyme was greater than that of the free enzyme. The enzyme retained higher activity levels under extreme conditions, and the fluidized-bed reactor showed better juice clarification capacity compared to the packed-bed reactor.

Summary: This study aimed to obtain the optimal conditions for microencapsulation of echium oil using spray drying. The results showed that the optimum emulsion conditions were 89.7% maltodextrin:10.3% modified starch, 16.0% oil concentration, and homogenization speed of 14.8 x 10(3) rpm. For encapsulation, the optimal conditions were 140°C inlet temperature, 30% airflow rate, and 15% pump rate.

Summary: A new method for thermocatalytic degradation of dispersed oil using a thermocatalyst, Sr0.85Ce0.15FeO3 perovskite, is proposed, which utilizes the thermal energy in produced water. Experimental results show that higher perovskite concentrations lead to faster removal of oil, with initial removal being adsorption to the perovskite surface followed by catalytic degradation.

Summary: A novel pseudotargeted lipidomics strategy was developed for comprehensive profiling and structural elucidation of polyunsaturated lipid-rich echium oil. A total of 209 lipid species were profiled, with 162 unsaturated lipids identified and 42 groups of omega-3 and omega-6 C=C location isomers discovered through this approach. This strategy is expected to provide new insights into structural characterization of distinctive bioactive lipids in food.

Summary: A novel enzymatic packed bed membrane reactor (EPBMR) was developed by integrating advantages of packed bed reactor (PBR) and enzymatic membrane reactor (EMR). The use of microspheres enlarged the contact area between enzymes and substrates and reduced membrane fouling. The system exhibited a high sucrose conversion rate after 36 hours of continuous operation.

Summary: This study introduces a novel forward mixed multistage packed bed reactor (FMMPBR) for methanol synthesis. The FMMPBR is divided into multiple stages with flow diverters to optimize reactant concentration and catalyst amount. Through simulation and optimization, the FMMPBR shows higher carbon conversion and lower catalyst requirement compared to the standard tubular reactor. Additionally, it achieves reduced temperature deviation and higher production rate.

Summary: In this study, a continuous-flow packed bed electrode reactor (PBER) was developed to reclaim oil sands process water (OSPW). The PBER, constructed with a two-dimensional electrode system (2-DES) and spherical activated carbon (SAC), demonstrated superior degradation of dissolved organic matters (DOMs) in OSPW compared to the 2-DES. Under optimized conditions, the PBER achieved high COD and DOC removal percentages, improved energy consumption and current efficiency, and effectively degraded the primary source of acute toxicity in OSPW.

Summary: Research has shown that enzyme-catalyzed reactions in supercritical CO2 can produce solvent-free natural products enriched in bioactive substances. The method offers advantages such as easy adjustment of CO2 properties and low mass transfer limitations, but its potential for large-scale application depends on enzyme stability in CO2. A mathematical model for immobilized lipase-catalyzed vegetable oil hydrolysis in a continuous-flow reactor was developed, and reaction rate constants and glycerol adsorption parameters were estimated. The rate-controlling step was found to be the hydrolysis of triglycerides, with a kinetic constant dependent on pressure and temperature.

Summary: This study aimed to synthesize medium-long-medium (MLM) triacylglycerols with nutraceutical applications through enzymatic acidolysis in a fluidized bed reactor. The optimal conditions were found to be a 1:4 oil/acid molar ratio and 80 cycles, resulting in a degree of incorporation of about 40 mol%.
