What is Shellac Red?
Shellac Red is also called shellac red. The coloring ingredients are a mixture of five ingredients: lac acid A, lac acid B, lac acid C, lac acid D, and lac acid E, of which lac acid A accounts for 85%. Lac dyer red is highly safe and is suitable for beverages that do not contain protein or starch, candies and jellies, pastries, etc.
Properties
Lac red is a bright red or purple powder or liquid, slightly soluble in water, ethanol and propylene glycol, with low solubility. At 20°C, the solubility is 0.0335% (water) and 0.916% (95% ethanol), and the higher the purity, the lower the solubility in water. The color tone changes with the pH of the environment. It is orange-yellow when the pH value is less than 4.0; bright red when the pH value is 4.0-5.0; purple-red when the pH value is greater than 6.0; it fades when the strong base pH value is greater than 12. It has good light and heat stability in acidic media. It is stable to vitamin C and hardly fades. It is very sensitive to metal ions, especially iron ions above 6-10μg/g, which can make the pigment black. The coloring properties of this product change with pH. The closer to neutral, the worse the coloring properties, and the better the acidity. It is most suitable for beverages, candies and jellies, pastries and noodles that do not contain protein or starch.
