natural food pigment Lac dye factory
is extracted from laccifer lacca by weak alkali solution and refining.
main composition: laccaic acid a(85%) and laccaic acid b, c, d, e ,etc.
properties: red or red-purple powder. in aqueous solution its color vary with its ph. when ph is 3-5, it is orange-red, ph is 5-7 red to red-purple color. when ph is more than 7, it is red-purple. the resistance to light and heat is good in acid medium. powder dissolves in water (0.1%), in alcohol and propanediol, pass through 80-mesh-screen.
applications/use rates:
fruit preps, beverages; 0.05-0.20
storage conditions:
avoid exposure to heat, air, and light. recommended storing at refrigerator conditions for maximum shelf life of 2 years.
