Density | 1.2096 (rough estimate) |
Boling Point | 886.32°C (rough estimate) |
Appearance | Powder |
Storage Condition | Room Temprature |
Refractive Index | 1.704 |
Physical and Chemical Properties | White to pale yellow fibrous powder or coarse powder. Almost odorless and tasteless. Dissolved in water to form a viscous colloidal solution. Dissolved in dilute organic acid solution, and dissolved in ethanol aqueous solution with concentration below 60% according to the degree of esterification. |
Use | Use stabilizer; Thickener; Emulsifier; Foaming agent; Spice extraction solvent. In addition to having colloidal properties, because of the propylene glycol group in the molecule, it is lipophilic and has good emulsion stability. Commonly used in lactic acid beverages, fruit drinks and other low pH range of food. |

Summary:
Propylene Glycol Alginate,PGA) is made by deep processing of alginic acid extracted from natural seaweed. Its molecular structure has both hydrophilic and lipophilic groups, and it itself is a product with a pH value of 3~4. Therefore, compared with alginate, PGA has stronger emulsification, stability and acid resistance, and has a good improvement effect when applied in acidic brown milk drinks.

Summary:
Different amounts of propylene glycol alginate (PGA) were added to the raw milk for fermentation, and its characteristics were tested. The results show that after adding PGA, the viscosity of yoghurt increases significantly and forms a thixotropic ring, which is a kind of thixotropic fluid. Among them, the thixotropic ring area with PGA addition of 0.20% is the largest, which is 20 431.43. The change curve of the apparent viscosity of yoghurt with shear time conforms to the change rule of power function y = kx-n, R2 = 0.975 3; Experiments show that different addition amounts of PGA can affect the structure of yoghurt to varying degrees, and the addition amount of 0.20% has the best effect: at this time, the water holding capacity of the sample rises by 10.9%? The amount of whey precipitation decreased by 26.0%, and the hardness was 8g.

Summary:
Clouding agent, also known as turbidity agent, is an emulsion stabilizer. Its function is to emulsify, thicken and stabilize the solution, so that the water and oil solution that is not easy to melt can form a colloidal dispersion with uniform mixing, which can prevent precipitation and increase the taste. Since propylene glycol alginate contains hydrophilic and lipophilic groups, it can be added to beverages and foods to emulsify and thicken. It is a natural clouding agent. It is used in sports beverages and various fruit juice beverages., Probiotics, lactic acid bacteria beverages, jelly and other foods have good application value.
