Herbridge, 28 Mar.2011_Yunnan Tonghai Yang Natural Products Co., Ltd, the largest supplier of radish red products in the world, has launched Lac Dye Red based on unsurpassed natural resources in Yunnan province, further expanding its portfolio of natural pigments.

With lac acid A and lac acid B, C, D and E as main components, Lac Dye Red is extracted from resinlike substance secreted by female lac insects. The color varies with pH. It is orange red in acid solutions (pH 3-5); red to reddish violet in neutral solutions( pH 5-7) and reddish violet in alkaline solutions (pH＞7). Lac Dye Red is heat- and light-stable in acid solutions. It remains stable even after two hours' heating at 100℃. But in alkaline solutions, it is heat- and light-unstable and sensitive to metal ions, especially iron ion.

As a brown powder, water soluble Lac Dye Red can fully disperse in water. Tonghai Yang supplies water-soluble Lac Dye Red featured by E70 and E150. The company also supplies common Lac Dye Red, a bright red powder which is slightly soluble in water and soluble in alcohol and propylene glycol.

According to herbridge.com, Lac Dye Red has been recognized as food additives in China. Lac Dye Red is allowed to use in a wide range of applications, including juice, fruit drink, carbonated beverages, flavorings, jams, cocoa preparations, chocolate and chocolate products, candy and liquor preparation.

Founded in 1996, Yunnan Tonghai Yang Natural Products features by deodorized Tonghai Radish Red, deodorized Red Cabbage Color and deodorized Purple Sweet Potato Color.
