Three different methods for extracting red pigment from lycium barbarum were compared and the stability of this red pigment was studied. The experimental results showed that the flooding extraction is superior to other two methods. The red pigment is resistant to heat, acid and base, and keeps stable in the presence of Cu²⁺ and Ca²⁺ ions.So this technique is expected to be used extensively.
- lycium barbarum,
- pigment,
- flooding extraction
