| Study on Extraction of Date-Red Pigment and Its Stability |
|
|
| Abstract: |
| The extraction of date-red pigment and its stability were studied. The results showed that the pigment was water soluble, and it was stabal to heat and light. It was also stabal in solutions of hydrochloric acid, sodium hydroxide, metal ions, oxidizers and sucrose, etc; However, it was less stabal to negative ions, reductants, vitamin C, sodium benzoate, potassium sorbate, etc. |
| Key words: date-red pigment extraction stability |
