4. Conclusion
Mulberry fruit extract contains considerable amounts of anthocyanin,
especially the extract from the purple-colored mulberry.
Anthocyanin content is well correlated with antioxidant and its
tyrosinase inhibition activity. Anthocyanin, ascorbic acid and antioxidant
properties of mulberry fruit extracts decreased significantly
after exposure to heat at 70 C or light for 10 h. In order to
obtain the best quality of mulberry fruit extract, all processes
should be performed at a temperature lower than 70 C and should
be kept in a light-resistant container
