Propylene Glycol Alginate, also known as PGA, is a popular food additive used in numerous food and beverage products. This versatile ingredient functions as a stabilizer, emulsifier, and thickener in various food formulations. PGA is produced by reacting alginic acid, a natural polymer derived from seaweed, with propylene glycol. The food industry employs PGA in a vast array of applications, from dairy products and baked goods to meat products and beverages. PGA's ability to improve product texture and consistency makes it a valuable ingredient in food manufacturing.
Specifications
The product is available in the form of a white to light yellow powder or granules.
- Moisture: ≤15%
- PH: 7.0-9.5
- Viscosity (1% aqueous solution): ≥500 mPa.s
Applications
PGA is utilized in various dairy products including yogurt, cheese, and ice cream for the purpose of enhancing texture and providing improved stability.
PGA is commonly utilized in bakery products like cakes, bread, and pastries to enhance their texture, volume, and shelf life. Its inclusion results in improved characteristics of these delicious treats.
PGA is a versatile ingredient that can be applied to meat products, such as hot dogs and sausages, to enhance their overall quality. By utilizing PGA, there is an increase in the retention of water, which ultimately prevents the separation of fat and improves the texture of the meat. Therefore, it serves as a crucial component in the manufacturing process of such meat products, leading to the provision of high-quality meat products that are enjoyed by many.
PGA is a common ingredient found in several beverages such as sports drinks and fruit juices. It plays a vital role in enhancing the texture and consistency of these beverages, making them more appealing to consumers.
PGA is often added to sauces like mayonnaise and salad dressings to enhance their stability and emulsification. It is a common ingredient used for this purpose.
Storage Condition
To maintain the quality of PGA, it is crucial to store it in a well-ventilated area that is cool, dry, and shielded from direct sunlight, excessive heat, and moisture. Utilizing airtight containers is essential as it prevents any possible contamination or absorption of moisture. It is important to note that PGA has a shelf life of roughly two years.
Functional Characteristics
Alginated glycol ester, also known as PGA, is a marine food additive that is made from processing alginic acid that has been extracted from natural seaweed. This powder is either white or a pale shade of yellow, depending on its purity. When mixed with water, it forms a thick and viscous colloid that is ideal for a range of applications. Since PGA has stronger acid resistance compared with regular sea alginate, it is better suited for use in food products. All in all, this marine-based ingredient offers excellent performance and serves as a valuable resource for the food industry.
The Main Purpose
Thickening, emulsifying and stabilizing are common uses of this substance in the food industry.
The algroscopic glycols possess high resistance to acids and can effectively function in environments with a pH range of 3 to 5.
Algroscopic glycol ester is commonly employed in the production of various consumer goods such as yogurt products, seasonings, and beer foam stabilizers. This versatile compound is highly regarded for its exceptional foaming and emulsification properties. It finds widespread application due to its ability to enhance the texture and stability of these products. Specifically, it aids in creating a creamy and smooth consistency in yogurts, improves the dispersal of flavors in seasonings, and ensures the longevity of the foam in beers. Its effectiveness in these areas has made it a popular choice among manufacturers in the food and beverage industry.
Propylene glycol alginic acid is a mixture that possesses numerous noteworthy characteristics such as hydrophilic, anti-aging, and organizational enhancement. This combination is particularly suitable for use in various food products such as dry noodles, raw wet noodles, convenient rice noodles, frozen rice noodles, pastries, and bread. The reason for its suitability in these products is due to the fact that it enhances the overall quality, texture, and taste of the food. Its anti-aging properties also ensure that the food products can last longer on the shelf without becoming stale or losing their overall quality. This makes propylene glycol alginic acid a valuable ingredient for food manufacturers seeking to improve the quality and shelf life of their products.
