Abstract:
Chuan Chenpi (CCP), the peel of the ancient Chinese citrus variety Citrus reticulata 'Dahongpao', enhances its edible and medicinal value through aging. This study focuses on CCP samples aged 1-8 years, aiming to explore the dynamic changes during aging. Although aging induced noticeable changes in color, Fourier Transform Infrared (FTIR) analysis revealed no significant alterations in functional groups. Volatile and non-volatile metabolomic analyses indicated that aging primarily affects metabolite content rather than types, and both composition and antioxidant activity reached relatively high levels in the fourth year. The experimental results illustrate that the improvement in CCP quality induced by aging does not follow a linear pattern but exhibits fluctuations. The findings verify that the fourth year serves as a critical turning point for CCP's quality. This study clarifies the dynamic variation of chemical components in CCP during aging, thereby providing a scientific basis for the selection of its aging duration.
