Supercritical CO2 extraction of natural pigment from Citrus paradisi ‘Changshan Huyou’ cuticle

    Corresponding author: ZHONG Shan-min

Abstract: In order to obtain the optimal technical condition on the extraction of Citrus paradisi‘Changshan Huyou’and give a theoretic guarantee of extracting it in a large-scale and industrial way,cuticle of ‘Changshan Huyou’was studied with the supercritical CO2 technology. Factors affecting extraction such as time,pressure,95% ethanol dosage and temperature were studied. The results showed that the optimal technical condition of extracting natural pigment from‘Changshan Huyou’cuticle were as follows:extracting time was 2 h;extracting pressure was 25 MPa;95% ethanol dosage was 300 mL;extracting temperature was 35 ℃. After extracting,the liquid pigment was dried to a permanent weight to calculate the extraction rate. The extraction rate was 3.78%. [Ch,4 fig. 2 tab. 15 ref.]
