Present situation and prospect of edible pigment research;

Spectroscopic behaviour of edible pigment in PEG phase was investigated.

In order to search and develop more natural edible pigment, this paper is about extracting brown pigment from the seed of Longan.

Study on the dyeing properties of food pigment Sunset Yellow on cotton fabrics;

Research and development of anthraquinones food pigment;

Study on the extraction technology of food pigment extracted from chestnut shell;

Study on analytical method for inorganic anions in colorants by ion chromatography with ion exchange preseparation;

The adsorption character of five colorants and the elution behavior of seven inorganic anions on active carbon were systematically studied.

Adsorption character and conditions of the five colorants on three different kinds of adsorbent (polycaprolactam powder,active carbon,anion exchange resin)were systematically investigated.

Effects of edible pigments on dyeing of cut Gypsophila paniculata;

Research advances of application and detection methods of edible pigments in foods

Effects of edible pigments and chemical dyes on dyeing of cut Dendranthema flowers

Effects of food colors on dyeing of cut chrysanthemum;

" Xiufangbai" cultivar of white cut flower of chrysanthemum was dyed artificially with 3 kinds of food color, Apple Green ,Brilliant Blue and Ponceau 4R.

With excellent environment compatibility and dyeing properties, food pigments are not only used for food coloration.
