Figure 11: Elastic modulus of matured PSC/genipin gels obtained by a penetration test. (a) 0.5 and 0.15 wt% PSC gels containing genipin at concentrations ranging from 0 to 4 mM. (b) 0.5, 0.3, and 0.15 wt% PSC gels containing 2 mM genipin. The gels were matured by incubation for 72 h. Data are presented as mean ± SD; .
