45 min of UV treatment. The decrease of C* value may be attributed to
enzymatic oxidation of anthocyanins leading to losses of color brilliancy
(Holzwarth et al., 2012). In another study, thermosonicated strawberry
samples retained their color (Alexandre et al., 2011). Aday et al. (2013)
reported that changes in L* values in US treated strawberries were not
significantly important. However, 90 W treatment had an adverse effect
on the anthocyanins' stability. Moreover they reported that the
