0 h data of each treatment in same experimental data is same because 0 h reaction time means non treated.
Means with different capital letters are significantly different (p<0.05) when comparing treatment type at each time.
Means with different small letters are significantly different (p<0.05) when comparing reaction time in the same treatment type.
DW, distilled water; DW E, 1% (w/v) bromelain in distilled water; DE, blank double emulsion; DE E, 1% (w/v) bromelain in internal aqueous phase of double emulsion.
