Total phenolic content in strawberry fruit with or without treat-ment increased gradually with storage time. Blue light treatment maintained significantly (p < 0.05) higher level of total phenolic after 2 days of storage (Fig. 5A). Corresponding to the changes in total phenolic content, DPPH radical scavenging activity in straw-berries increased gradually with the stroage time. Significantly (p < 0.05) higher DPPH radical scavenging activity was observed in blue light-treated fruit than that in control fruit after 4 days of storage (Fig. 5B).
