PENGARUH BEBERAPA PERLAKUAN TERHADAP PENGURANGAN KADAR FORMALIN PADA IKAN YANG DITENTUKAN SECARA SPEKTROFOTOMETRI
ABSTRACT: The case of how
handling the fresh fish which used the dangerous chemical material (formaldehyde)
is still found in society, so that is why it is necesarry to find the safety
way tohandle the fresh fish in. It has been held the research about the
influence of on the effect ofsome treatment in reduction the formaldehyde level
on fish determined by spectrophotometryUV-Visible at wavelength 412 nm and
40°C. In the preliminary research the fish is soaked in formaldehyde liquid
(100 mg/mL) for 24 hours, then washed, soaked and boiled. Then, the filtrate is
reacted with Nash reagent. The yellow color which has formed was measured at λ
412 nm. The result shows there is the reduction of formaldehyde level in the
sample about 43.9 % after washing, 33.3 % after soaking, 53.8 % after boiling.
After that, the fish that was spread inthe market which suspected containing
the formaldehyde then washed, soaked and boiled. The result shows there is the
reduction of formalin level in sample 1 about 22,7 % after washing, 17.0% after
soaking, and 96.1 % after boiling. While in sample 2, 41.8 % after washing,
56.2 %after soaking, and 95.4 % after boiling.
