96% with a standard deviation of 7%. The confirmation ions for MCW-2, M-3625 and
M-3627 yielded acceptable recoveries at both fortification levels and the overall average
recoveries were acceptable. Representative chromatograms of control and fortified
tomato samples are presented in Figures 29 through 31.
Method validation for MCW-2, M-3625 and M-3627 in pepper followed the same
method as was used in the tomato method validation. The pepper validation included
with two controls, five (5) replicates at 0.01 ppm and 5 replicates at 0.10 ppm. The
average percent recovery for MCW-2 was 103% at 0.01 ppm and 106% at 0.10 ppm. The
overall average percent recovery of MCW-2 in peppers was 105% with a standard
deviation of 9%. The average percent recovery of M-3625 was 100% at 0.01 ppm and
94% at 0.10 ppm. The overall average percent recovery of M-3625 in peppers was 97%
with a standard deviation of 7%. The average percent recovery of M-3627 was 84% at
0.01 ppm and 95% at 0.10 ppm. The overall average percent recovery of M-3627 in
peppers was 90% with a standard deviation of 7%. The confirmation ions for MCW-2,
M-3625 and M-3627 yielded acceptable recoveries at both fortification levels and the
overall average recoveries were acceptable in peppers. Representative control and
fortified pepper chromatograms are presented in Figures 32 through 34.
Method validation was similarly carried out in cucumbers. The cucumber validation
included two controls, five (5) replicates at 0.01 ppm and 5 replicates at 0.10 ppm. The
average percent recovery for MCW-2 was 103% at 0.01 ppm and 89% at 0.10 ppm. The
overall average percent recovery of MCW-2 in cucumber was 96% with a standard
deviation of 8%. The average percent recovery of M-3625 was 103% at 0.01 ppm and
97% at 0.10 ppm. The overall average percent recovery of M-3625 in cucumber was
100% with a standard deviation of 6%. The average percent recovery of M-3627 was
86% at 0.01 ppm and 97% at 0.10 ppm. The overall average percent recovery of M-3627
in cucumber was 92% with a standard deviation of 7%. The confirmation ions for MCW-
2, M-3625 and M-3627 yielded acceptable recoveries at both fortification levels and the
overall average recoveries were acceptable in cucumber. Representative control and
fortified cucumber chromatograms are presented in Figures 35 through 37.
Method validation for MCW-2, M-3625 and M-3627 in melon included with two
controls, five (5) replicates at 0.01 ppm and 5 replicates at 0.10 ppm. The average percent
recovery for MCW-2 was 101% at 0.01 ppm and 96% at 0.10 ppm. The overall average
percent recovery of MCW-2 in melon was 98% with a standard deviation of 5%. The
