OIL-SOLUBLE BEETROOT RED PIGMENT AND PREPARATION METHOD AND APPLICATION THEREOF
The present invention belongs to the field of natural pigment modification and specifically relates to an oil-soluble beetroot red pigment, its preparation method and application. An aqueous solution containing beetroot red pigment and phospholipids is added to an aqueous solution containing water-soluble proteins and/or water-soluble peptides, and the mixture is dried to obtain an oil-soluble beetroot red pigment composite powder. The powder is subjected to low-temperature ultra-fine grinding to produce ultra-fine oil-soluble beetroot red pigment powder. Finally, the ultra-fine powder is added to vegetable oil and processed through a ball mill-colloid mill cycle to obtain the oil-soluble beetroot red pigment. The oil-soluble beetroot red pigment requires no chemical modification and contains no synthetic emulsifiers or additives. The materials used are natural and safe, improving the light stability and thermal stability of beetroot red pigment, expanding its application scope, and providing a viable alternative to industrially synthesized oil-soluble pigments.
