How temperature influence stability of emulsion? 


Best insight from top research papers

The stability of emulsions is influenced by temperature. Elevated temperatures can act as an artificial breakdown stress, accelerating the normal mechanism of emulsion breakdown and leading to decreased stability . Heating emulsions can cause the coalescence of dispersed globules, resulting in a decrease in stability . However, the effect of temperature on emulsion stability can vary depending on the specific emulsion system. For example, in the case of biodiesel/diesel blend nanoemulsions, an increase in temperature up to 50 °C was found to have a moderate effect on the mean droplet size, especially when the concentration of biodiesel in the emulsified fuel blend is less than 15 vol % . On the other hand, in Pickering emulsions stabilized by konjac glucomannan (KGM), an increase in temperature did not significantly affect the stability of the emulsion when KGM concentration and oil content were optimized . Therefore, the influence of temperature on emulsion stability depends on the specific emulsion system and its components.

The paper mentions that elevated temperature can be used as an artificial breakdown stress to assess the stability of emulsions. Heating accelerates the normal mechanism of breakdown, making it a form of artificial aging.
The paper discusses the influence of temperature on the stability of Pickering emulsions. It states that emulsions without konjac glucomannan (KGM) became unstable and delaminated after heat treatment at 100 °C. However, emulsions with KGM and higher oil content exhibited improved thermal stability.
The paper states that the emulsified fuels are highly stable within the temperature range of up to 50 °C. It also mentions that there is a moderate change in mean droplet size, especially when the concentration of biodiesel in the emulsified fuel blend is less than 15 vol %.
The paper states that emulsions stabilized by functionalized milk protein concentrate (f-MPC) remained stable even after heating at 121 °C for 15 minutes, while emulsions stabilized by commercial MPC and mayonnaise disintegrated upon heating. Therefore, temperature can influence the stability of emulsions.

How does the fermentation process affect the formation and stability of emulsions?4 answersThe fermentation process plays a crucial role in enhancing the formation and stability of emulsions. Fermentation with lactic acid bacteria can lead to the modification of food ingredients, such as phosvitin, into peptides that improve emulsifying properties and bioactivity. Microorganisms used in fermentation can create emulsifiers capable of forming reverse micelles, aiding in the effective penetration and absorption of bioactive substances into the skin, thus improving emulsion stability and skin cell toxicity. Additionally, the stability of emulsions can be attributed to factors like stirring velocity, time, and the ratios of surfactants to oil, which influence droplet size, phase viscosity, and coalescence, preventing settling or separation during fermentation. Yeast cells, depending on their physiological state and cultivation medium, can also contribute to the stability of emulsions through mechanisms like electrostatic repulsion between droplets.
Which is the role of temperature in olive oil emulsion's stability?5 answersThe stability of olive oil emulsions is influenced by temperature. The emulsions were found to be stable when stored at 4 °C, but unstable when stored at 25 °C and 40 °C. Similarly, emulsions containing olive oil were stable at 4 °C and room temperature, but less stable at 40 °C. The stability of the emulsion was also examined through an accelerated aging test at 45 °C, where emulsions with a water to oil ratio of 2:8 were found to be the most stable, showing no phase separation. The droplet size of the emulsions remained stable around 2.5 μm throughout the storage period. Overall, temperature plays a crucial role in the stability of olive oil emulsions, with lower temperatures being more favorable for maintaining stability.
How does temperature affect the stability of olive oil emulsions?5 answersTemperature has a significant effect on the stability of olive oil emulsions. Low temperatures, such as 4 °C and -18 °C, can maintain the stability of olive oil emulsions for up to 36 months, preserving the quality and preventing degradation of important compounds. On the other hand, higher temperatures, such as 25 °C and 40 °C, can lead to instability and degradation of the emulsions. The temperature at which the emulsion is mixed also plays a role in stability, with a mixing temperature of 36 °C resulting in the highest oxidation stability of the olive oil. Overall, it is important to store olive oil emulsions at low temperatures, such as 4 °C, to maintain their stability and preserve their quality.
Is the occurrence of cavitation is largely responsible for the effect of stabilizing emulsions?5 answersCavitation plays a significant role in stabilizing emulsions. The use of ultrasound and hydrodynamic cavitation has been explored to create stable oil-in-water emulsions. These techniques generate intense local shear and energy dissipation, leading to the formation of small droplets and high stability. The size of the emulsion droplets can be controlled by adjusting parameters such as inlet pressure, number of cavitation passes, and surfactant concentration. The stability of the emulsion is crucial for its successful encapsulation and delivery of bioactive compounds. Multilayer emulsions prepared using ultrasonication have been found to be the most stable against variations in physicochemical conditions. The cavitation process can also be used to prepare water-in-oil emulsions, with the size of water droplets ranging from 1 μm to 3 μm and 0.1 µm or less. Overall, cavitation is a promising technique for the formation and stabilization of emulsions.
How does ice crystals affect stability of emulsion gels?5 answersIce crystals can have an impact on the stability of emulsion gels. The presence of ice crystals during freezing can cause damage to the gel network, leading to a decrease in stability. However, the addition of certain substances, such as compound proteins or cellulose nanocrystals, can help alleviate this damage and improve the freeze-thaw stability of emulsion gels. These substances can form a protective layer around the emulsion droplets, preventing the formation of large ice crystals and maintaining the gel-like structure during freeze-thaw cycles. Additionally, the incorporation of these substances can also enhance the water holding capacity of the gels and delay protein oxidation, further contributing to their stability. Overall, controlling the formation and size of ice crystals is crucial for maintaining the stability of emulsion gels during freezing and thawing processes.
Which is the role of temperature in emulsion's stability?4 answersTemperature plays a significant role in the stability of emulsions. In the context of crude oil emulsion, the rheological properties of low-viscous emulsions are affected by temperature, with higher temperatures leading to shear thinning behavior. In the case of carotenoid emulsions, temperature affects the chemical stability of lutein, with lower temperatures enhancing its stability during storage. Emulsified acid stability is also influenced by temperature, with microscopic characteristics such as droplet size and placement playing a determinative role in emulsion stability. Additionally, temperature affects the freeze-thaw stability of oil-in-water emulsions, with emulsions prepared with certain sucrose esters of fatty acids showing smaller droplet sizes and narrower particle-size distributions at higher temperatures. Overall, temperature is an important factor that can impact the stability of emulsions in various applications.
