Figure 1. Mean results ± standard deviation of (A) malodor levels as scored by judge 1 () and judge 2 () (with results presented on a semi-integer scale of 0–5), and (B) volatile sulfide levels measured with the use of a sulfide monitor (Halimeter^TM), as ppb sulfide equivalents. * indicates high significance (p = 0.026 and p = 0.015 for judges 1 and 2, respectively, N = 6).
