The mian raw material in this research is apricot dregs which is the by-products of concentrated apricot pulp.The extraction techniques and the stability of pigment from apricot residue were studied in this paper.The results showed that the maximum absorption wavelength of the pigment was λmax =410nm.The optimal extractant is alcohol.The optimum extraction conditions were:concentration of extractant was 70%

extraction time was 2.5 hours and temperature of extraction 700C.It is quite stable

lightfast

heatproof

alkali resistance

antioxidizing and antireducing.The pigments are hardly affected by common food additives

such as sucrose

glucose

sodium benzoate

Vc and Fe3+、Mg2+、Al3+、Ca2+and Cu2+.It was found that salt and citric acid had effects of tone fortification on the pigment.
