Storage study of mengkudu (Morinda citrifolia L.) extract was carried out to determine the effects of canning and storage period on pH, total polyphenol content, antioxidant activity, intensity of off-odour and aroma acceptance. Uncanned (control) and canned extract were stored for 0, 8, 16 and 24 weeks under room temperature. Results showed canning resulted in a significant (p<0.05) reduction in pH, total polyphenol content, antioxidant activity and off-odor intensity. However, canning also resulted in a significantly (p<0.05) higher aroma acceptance. pH and antioxidant activity were significantly (p<0.05) affected by storage period. However, for both control and canned extract, storage period did not significantly (p>0.05) affect total polyphenol content during 24 weeks of storage.
