Abstract

Ponkan mandarin is a promising variety of citrus fruit for juice production. However, there is little knowledge in shelf-stability of Ponkan juice under normal sun lighting. In this study, Ponkan juice was investigated for the changes of quality under the most common powerful irradiation of sunlight, ultraviolet A (UVA). Properties related to taste, color, nutritive values, characteristic mandarin aroma, and volatile sulfuric off-flavor were analyzed to make a comprehensive evaluation. The results showed that after 50 days UVA radiation through PET bottles at 25°C, juice acidity, total soluble solid content, chromaticity values, vitamin C and B2 content decreased significantly, and the characteristic mandarin aroma weakened. In addition, 10 more volatile sulfur compounds introducing distinctly off-putting smell were detected than the fresh juice. UVA is responsible for the accelerated deterioration of Ponkan juice quality and should be properly shielded.
