Research on the Extraction and Stability of Cyanidin in Lycium ruthenicum Murr
This study focuses on the cyanidin extracted from Lycium ruthenicum Murr.Single-factor experiments were con-ducted to investigate the effects of ethanol concentration,solid-liquid ratio,extraction time,and extraction temperature on the extraction efficiency of cyanidin.Furthermore,an optimized extraction process was obtained using response surface methodology.Additionally,the effects of different types and concentrations of starch and amino acids on the stability of cy-anidin were examined,and the results indicated that they contribute to enhancing the stability of cyanidin.
