ABSTRACT: The research about
validation of visible spectrophotometry method to analyze formalin in tofu had been carried
out. The aim of this
research was to
determine several validation
parameters such as precision,
linearity, accuracy, Limit
of detection (LOD)
and Limit of
quantification (LOQ). Formalin
was added Nash reagent
then detected using
spectrophotometer at wave
length 412 nm.The
results of the research showed that validation
parameters values for accuracy was 102,84%; standard deviation value for
formalin was 1,198%; linearity value for formalin was 0,9994; LOD was 0,0375
μg/mL and LOQ was 0,1250 μg/mL, respectively. Due to the result of the
research, visible spectrophotometry method to analyze formalin in tofu was
valid.
Key words: Validation,
spectrophotometry, LOQ, LOD
