Propionic acid (PA) is commonly present in Emmental cheese (EM) with relatively high concentration. Even though PA is allowed as GRAS in the USA, it may cause neurological disorders if it is consumed excessively. The maximum level of the preservative PA in cheese is set at 3.0 g/kg by the Korean Food Code. Also, the minimum level of PA in EM (150 mg / 100 g) was set by Codex in 1967. Therefore, PA monitoring in EM, with relatively high level of intrinsic PA, is necessary to recommend the sound use of the PA in the EM ripened. The current official PA analysis method consisting of steam distillation and solvent extraction / evaporation, is too cumbersome to be handled in sample preparation process. In this study, acidic acetone-based direct extraction method was successfully applied to 12 EM samples for the determination of PA level.

Liquid crystals (LCs) are widely used as promising stimuli-responsive materials due to their unique combination of liquid and crystalline properties, providing the capability to sense even molecular-scale events and amplify them into macroscopic optical outputs. However, encoding a high level of selectivity to a specific intermolecular event remains a key challenge, leading to prior studies regarding chemically functionalized LC interfaces. Herein, we propose an integrative strategy to significantly advance the design of chemo-responsive LCs through a deep fundamental understanding on the orientational coupling of LCs with new functional molecules, organic ionic plastic crystals (OIs), presented at LC interfaces.

Background: Short-chain fatty acids (SCFAs), including propionic acid (PA), are key in immunological research. Supplementing PA has shown benefits for autoimmune diseases. A comprehensive understanding of the PA pharmacokinetics is essential for the optimal design and execution of studies utilizing orally administered PA.
