Figure 3.

Total antioxidant activity in pepsin hydrolyzed proteins (A,B) and collagenase hydrolyzed peptides (C,D) from freeze-dried tissues of Aurelia sp.1, C. tuberculata and R. pulmo. Chicken collagen was hydrolyzed in parallel and used as a comparison. Antioxidant activity is expressed as nmol of Trolox eq. (TE) per gram of dry weight (DW) (A,C) or as nmol TE per mg of proteins (B,D). Data are the mean of three independent experiments performed in triplicate, bars represent mean ± standard deviation (SD). A,B,C: the different capital letters inside the figures indicate differences among species for the same treatment type; a,b,c: the different lower case letters inside the figures indicate significant differences among treatments in the same jellyfish species, (p < 0.05).
