Function
The main uses of citretin powder include food coloring, biological tissue imaging, and non-invasive detection.
1. Food coloring
Lemon yellow pigment is a water-soluble synthetic pigment, bright yellow, widely used in food, beverage, medicine, cosmetics, feed, tobacco, toys, food packaging materials and other coloring. It is also used for dyeing wool and silk and for making color lakes . Citretin is safe when used in moderation and does not pose a hazard to humans .
2. Biological tissue imaging
Lemon yellow also has important applications in biological tissue imaging. The researchers found that applying a lemon yellow solution to the epidermis of laboratory mice made the skin and muscles transparent at a specific frequency spectrum, revealing internal organs. This approach can significantly enhance the effectiveness of some biological tissue imaging techniques, such as the direct observation of blood vessel distribution in the brain and muscle fiber structure 45. The principle of this phenomenon is that lemon yellow dissolved in the water of biological tissue can increase the refractive index of the water, so that it is more consistent with the lipids in the cell, reducing the scattering of light .
3. Non-invasive detection technology
The application of Lemon yellow is not limited to biological tissue imaging, but can also develop new non-invasive detection techniques. By applying lemon yellow solution, the activity of internal organs, such as intestinal peristalsis and cardiorespiratory activity, can be observed without invading the skin. The method is non-invasive and reversible, and simply washes away the dye with water to restore the opaque skin .
