Phospholipids Powder Price

The changes in phospholipids at different temperatures are mainly reflected in their physical properties, chemical properties, and biological activity. The physical changes include color and fluidity. The color of phospholipids can change with temperature. At lower temperatures, their color may be relatively light, but as the temperature rises, the color gradually deepens. Particularly at temperatures reaching 70°C, the color change becomes very noticeable, possibly even turning black. As the temperature rises, the fluidity of phospholipids also increases. At lower temperatures, phospholipid molecules may be tightly arranged, resulting in poor fluidity. However, when the temperature rises to a certain level, the molecular movement speeds up, significantly improving fluidity. Generally, at 55°C, the fluidity of phospholipids meets production requirements, and it continues to improve at higher temperatures.

The acid value of phospholipids increases with rising temperatures. Before 65°C, the acid value rises slowly with temperature changes. However, at 70°C, the acid value increases sharply, indicating possible carbonization reactions at this temperature, leading to a significant increase in acid value. Heating time also affects the acid value changes. At temperatures below 70°C, the longer the heating time, the acid value increases slowly. But at 70°C, the acid value rises more noticeably with heating time.

Although phospholipids are relatively stable under conventional environmental conditions, their oxidative stability may be affected at high temperatures. High temperatures accelerate the oxidation reactions of phospholipid molecules, reducing oxidative stability. Therefore, during storage and use, prolonged exposure to high-temperature environments should be avoided.

Phospholipids are an essential component of biological membranes and play a crucial role in the normal physiological functions of cells. Their biological activity can be affected by high temperatures, which may disrupt the molecular structure and lead to reduced or lost biological activity. Therefore, in biomedical applications, it is essential to control the temperature to avoid adversely affecting the biological activity of phospholipids.

The changes in phospholipids at different temperatures are primarily reflected in their physical properties, chemical properties, and biological activity. To maintain their stability and biological activity, it is necessary to strictly control temperature conditions during storage and use. The processing and application of phospholipids also need to be adjusted and optimized according to specific temperature conditions.
