Seiler M, Stock S, Drews A. pH-dependent electrostatic interactions between enzymes and nanoparticles in Pickering emulsions - Influence on activity and droplet size. J Biotechnol 2024; 382:28-36.

Abstract
Pickering emulsions (PE) are liquid-liquid systems that are stabilized by solid (nano)particles at the fluid interface. They offer higher stability, easier separation and lower toxicity compared to classical emulsions stabilized by surfactants. Common applications range from food science to drug delivery. In the last decade they have become of more interest in the field of multiphasic biocatalysis. First, this study aims to present the influence of pH, salt strength and particle charge on enzyme activity. The different behavior of two lipases (CaLA and CRL) is shown. While the activity optimum of CaLA changed from pH 6.5 to pH 5 by applying particles with negative instead of positive surface charge, the CRL activity optimum stayed at pH 5-5.5. This enables particle charge as an additional parameter to optimize biocatalytic reactions in PEs. Second, the resulting drop sizes were measured to elucidate further interactions between the enzymes and particles in PEs. Drop sizes in PEs prepared with CaLA were not influenced by pH, but increased for positively and decreased for negatively charged particles upon the addition of CaLA. Electrostatic attraction between particles and CRL increased the droplet diameter from 10 μm up to 30 μm and therefore destabilized the PE for both particle types.

Abstract
Menthol inclusion complexes (ICs) have addressed a range of opportunities in food applications due to their volatile resistance. However, previous protocols used for their synthesis give low yields and high industrial application costs. In the present investigation, metal-organic frameworks based on β-cyclodextrin (β-CD-MOF) have been prepared for the molecular encapsulation of menthol. Menthol/β-CD-MOF-IC was synthesized under the optimized parameters, after which release behavior was studied. In this optimized manner, a higher menthol capacity was obtained in which the menthol content and encapsulation efficiency were 27.1 and 30.6%, respectively. Compared with menthol/β-CD-IC, menthol/β-CD-MOF-IC is resistant to high temperature, but sensitive to moisture. In a simulated oral release experiment, the rate of menthol release from different samples followed the order of: pure menthol > β-CD > β-CD-MOF, which can be attributed to two mechanisms: non-specific binding and site preference. We propose that β-CD-MOF can be used as a promising delivery system for aroma compounds.

Abstract
A porous crosslinked starch polymer (CSTO) using bitolylene diisocyanate as crosslinker was prepared by a facile method and used to selectively recover acetophenone (AP) from petrochemical effluent mainly containing AP and 1-phenylethanol (PE). The theoretical calculation results indicated that AP exhibited the superior affinity toward the adsorption sites of CSTO through noncovalent interactions. The adsorption measurements showed that, due to the large surface area and high affinity of phenyl rings, CSTO displayed an extremely rapid adsorption rate, a desirable adsorption capacity and selectivity to AP. The adsorption kinetics and isotherms in single solute system agreed well with the pseudo-second-order kinetic model and Freundlich isotherm model, and the adsorption was exothermic and spontaneous. Furthermore, CSTO showed excellent reusability for selective adsorption of AP from equimolar mixture of AP/PE, prompting us to further examine its applicability. In the practical application, CSTO also revealed a fast, preferential and reusable adsorption of AP from actual petrochemical effluent.

Abstract
Abstract
l-menthol has been widely used in flavour, food and pharmaceuticals. Because of its high volatility and whisker growth, l-menthol-hydroxypropyl-β-cyclodextrin inclusion complex was produced to improve shelf-life, provide protection, and enhance the stability of l-menthol. The inclusion complex was characterized by Fourier transform infrared spectroscopy, X-ray diffraction. The results show that l-menthol was successfully encapsulated in hydroxypropyl-β-cyclodextrin. l-menthol loading capacity is about 8.44%. Geometries and binding energies of l-menthol-hydroxypropyl-β-cyclodextrin inclusion complexes were investigated using molecular mechanics calculations. The shape and orientation of the most stable complex, and the minimum binding energy were determined. L-menthol release from complex was determined by thermogravimetric analysis. Two l-menthol release rate peaks were observed at 69.3 and 279.1°C. The l-menthol release reaction order, release activation energy and the preexponential factor were obtained.
