Carthamins yellow
Carthamins yellow, also known as saffron yellow, is a natural food additive with the petals of the safflower (Carthamus tinctorius L.) as raw materials, extracted by water and refined. Carthamins yellow is easy to absorb moisture, brown and caked after moisture absorption, but it does not affect the use effect. The melting point is 230 ℃, and the color is relatively stable in the PH range of 5~7. It is quite stable to heat. When it is added to juice after 80℃ instant sterilization, the pigment residue rate is 70%. The PH was 7 and the pigment residual was 88.9% under sunlight for 8H. Combined with ascorbic acid can improve light and heat resistance.
Soluble in cold water (alkaline or acidic), hot water, dilute ethanol, dilute propylene glycol; Almost insoluble in anhydrous ethanol, insoluble in ether, petroleum ether, grease and acetone, etc. After dilution, the water solution was yellow, and the color changed from yellow to orange-yellow with the increase of pigment concentration. It is yellow in acidic solutions and orange in alkaline solutions. The heat resistance, reduction resistance, salt resistance and bacterial resistance of aqueous solution are strong. Water solution will fade or change color when it encounters calcium, tin, magnesium, copper, aluminum plasma, and will blacken when it encounters iron ions. Carthamins yellow has good coloring property for starch, but poor coloring property for protein.
