Phosphatidylserine is an important phospholipid compound. Pure Phosphatidylserine is widely used in foods, nutraceuticals and functional foods. due to its supportive effect on brain function. However, changes in pH in foods have a significant effect on the stability of phosphatidylserine. Especially in acidic and alkaline environments, the chemical structure of PS may change, thus affecting its activity and function. In this paper, we will explore in detail the effect of food pH on the stability of phosphatidylserine and introduce Guanjie Biotech's strengths in this area.
Phosphatidylserine in Food Application
Phosphatidylserine is a phospholipid-containing serine. It is a key component of biological membranes and is involved in cell signalling and the structural stability of cell membranes. Due to its role in promoting memory, relieving stress and improving cognitive function, Phosphatidylserine is widely used in a variety of functional foods and beverages.Guanjie Biotech produces soybean Phosphatidylserine and sunflower seed Phosphatidylserine. This includes pure Phosphatidylserine in granule, liquid and powder forms for different food addition needs.
Effect of pH on Phosphatidylserine Stability
The pH of a food significantly affects the stability of phosphatidylserine. Phosphatidylserine shows high stability in neutral or slightly acidic environments (pH 6-7). This is because the structure of phosphatidylserine is less likely to be disrupted at near-neutral pH. Its fatty acid chains and phosphate groups remain relatively stable. However, when the pH deviates from this range, the stability of PS can be challenged especially in more alkaline or acidic environments.
1. Effect of acidic environment (pH < 5)
At lower pH values (pH < 5), the phosphate group of phosphatidylserine is susceptible to protonation, leading to structural instability. This protonation can make PS more susceptible to hydrolysis reactions in acidic environments. Especially when exposed to an acidic environment for a long time, the degradation rate of PS will be accelerated. Therefore, special attention needs to be paid to the preservation conditions of PS when it is added to acidic foods such as yoghurt and fruit juices. This can avoid the reduction of activity due to an acidic environment.
2. Effect of alkaline environment (pH > 7.5)
The stability of pure phosphatidylserine is also affected in alkaline environments. In alkaline environments, the phosphate bond of PS may be affected by a hydrolysis reaction, which is especially significant at high temperatures. This hydrolysis reaction can lead to the breakage of fatty acid chains in the PS molecule, which in turn affects its effectiveness in foods. Therefore, when PS is added to alkaline foods such as certain protein drinks, appropriate protective measures need to be used to maintain its stability.
pH & Selection of Phosphatidylserine
• Phosphatidylserine Granules
It is suitable for neutral or weakly acidic foods. The phosphatidylserine granular allows for better mixing with the food matrix and provides stable results. It is especially suitable for use in cereal drinks and solid beverages.
• Phosphatidylserine liquid
Liquid phosphatidylserine provides better solubility in certain liquid foods. It is suitable for use in functional beverages. For acidic beverages, Guanjie Biotech offers phosphatidylserine oil that has been treated with a special process. This can improve its acid resistance to some extent and extend the shelf life of the product.
• Phosphatidylserine Powder
Bulk Phosphatidylserine Powder is suitable for addition to acidic and neutral food products. Guanjie Biotech produces Phosphatidylserine bulk Powder with high purity and stability. It can maintain its activity during a wide range of food processing. Pure Phosphatidylserine is particularly suitable for use in powdered punch and nutritional supplements
How to Improve Phosphatidylserine Stability by pH Adjustment?
To maintain the stability of pure phosphatidylserine in foods, phosphatidylserine manufacturers can optimise the addition of PS by adjusting the pH of the food. Below are a few commonly used methods.
• Use of buffering agents
By adding appropriate buffering agents to the food, the pH of the food can be stabilised within a certain range to reduce the effect on the stability of PS. Such as phosphate or citrate. For example, adding phosphate to acidic beverages can buffer the acidity and reduce the risk of PS degradation.
• Application of encapsulation technology
For bulk phosphatidylserine products that need to be used at extreme pH, microencapsulation technology can be used to protect the PS molecules. Guanjie Biotech is also continuously researching and applying microencapsulation technology. We want to improve the stability of pure Phosphatidylserine in different food environments, to meet the needs of more food manufacturers.
• Selection of suitable PS product form
Choosing the most suitable phosphatidylserine bulk form for different pH environments is also key to ensuring stability, and Guanjie Biotech offers a wide range of PS forms that allow customers to choose the most suitable product based on food characteristics and processing needs. This enables optimal stability in different pH environments.
The pH of the food product has a significant impact on the stability of pure phosphatidylserine. In acidic and alkaline environments, the chemical structure of PS may change, leading to a reduction in its activity and function. Guanjie Biotech is a Phosphatidylserine supplier. We offer a wide range of PS products from a variety of sources and forms. This includes Phosphatidylserine granules, Phosphatidylserine liquids, and Phosphatidylserine powders of soybean and sunflower seed origin. This allows for customised solutions to suit the needs of different food products.
