Summary: This study evaluated the effects of a peristaltic pump and a two-fluid pneumatic nozzle on the stability parameters of oil/water emulsions. The results showed that pumping and atomisation led to more homogeneous emulsions with smaller sizes and better stability. This study can contribute to determining operating conditions for encapsulating by spray drying.

Summary: This study investigated the effects of different carboxymethyl cellulose (CMC) concentrations on the properties of myofibrillar protein (MP)-soybean oil emulsions. The results showed that CMC addition improved the stability and texture of the emulsions, but decreased protein digestibility and water holding capacity. Lower CMC concentrations increased the hardness and gumminess of the emulsion gel, while higher concentrations decreased texture properties.

Summary: The quantitative effects of droplet size and emulsion viscosity on the storage stability of asphalt emulsion were studied. A model relating the storage stability to the droplet size and emulsion viscosity was proposed, and prediction models for the 1 day and 5 day storage stability were established. The results indicated that droplet diameter and emulsion viscosity were highly correlated with the storage stability. The proposed prediction equations can estimate the storage stability accurately and quickly.

Summary: This study aimed to investigate the correlation between the dynamic adsorption process of ultrasound-assisted cross-linked MP on the oil-water interface and the stability of the fabricated emulsion. The results showed that ultrasound treatment could effectively improve the interfacial properties and emulsion stability of MP molecules. The emulsion properties were positively correlated with the interfacial properties of MP. Among the ultrasonic groups, the E-MPU5 group exhibited the highest interfacial pressure, diffusion rate, penetration rate, rearrangement rate, dilatational modulus, elastic modulus, and E-pi slope. The corresponding emulsion had the smallest droplet size, highest adsorbed protein content, and highest absolute zeta potential value.

Summary: This study investigated the influence of homogenization pressure and cycles on the physical stability and droplet size distribution of zein emulsions. The results showed that homogenization pressure had the most significant impact on the stability and droplet size distribution, with an optimum pressure of 20,000 psi. It was also observed that the optimum number of cycles varied for different parameters, and both volumetric diameter and span value should be considered for obtaining stable zein emulsions.

Summary: In fatty acid (FA) overload models, acetylcholine (ACh) significantly enhances PLIN5 expression, improves LD lipolysis and LD-mitochondria association. Additionally, ACh reduces CD36 expression, decreases LD deposition and mitochondrial dysfunction, ultimately suppressing apoptosis in palmitate (PA)-treated neonatal rat ventricular cardiomyocytes (NRVCs).

Summary: A flow-focusing microfluidic device driven by pressure was used to produce soy protein emulsions with uniform droplet size and good morphology. The study showed that pressure played a crucial role in droplet formation, with the optimal parameters being a continuous phase pressure of 140 mbar and a dispersed phase pressure of 80 mbar. Emulsions prepared in this manner exhibited improved stability against temperature, pH, and salt concentration changes, as well as superior oxidative stability compared to those prepared by conventional methods utilizing homogenizers.

Summary: This study evaluated the effects of different mechanical emulsifying systems and sodium chloride concentrations on the physicochemical characteristics of bologna sausages. The results showed that cutter emulsification improved the emulsion stability of low-sodium sausages, while the continuous emulsifier had minimal impact on the extracted myofibrillar proteins.

Summary: This review provides a comprehensive overview of how different environmental stresses and processing conditions affect the stability of sodium caseinate (CAS)-stabilized emulsions and how to improve their stability. It summarizes the general properties of CAS as an emulsifier and the characterization of CAS-stabilized oil-in-water (O/W) emulsions. The major instability mechanisms in CAS-stabilized emulsions are presented, along with discussions on general factors such as pH, emulsifier concentration, ionic strength, oxidation, and processing conditions that affect the stability of CAS-stabilized O/W emulsions. Methods for evaluating emulsion stability and strategies to improve CAS-based emulsion stability are also described.

Summary: The study investigated the production of PFC-based nanoemulsions using a novel surfactant system to overcome challenges faced by PFC-in-Water emulsions. The fluorinated FC8 surfactant-based emulsion droplets were found to be smaller and more stable compared to Tween 80 alone, with improved droplet size distribution. This equimolar mixture of surfactants resulted in safer surfactant system with lower energy and operating costs for emulsions preparation.

Summary: This study aimed to enhance the physiochemical stability of chitosan particle stabilized Pickering emulsion by coating with sodium alginate. Different mass ratios of CS and SA were evaluated for their effects on the microstructure, rheology, and stability of the emulsions. The addition of the proper level of SA could increase the stability of the emulsion, but the creaming and flocculation stability were still sensitive to various environmental factors.
