| Summary: | Liquid smoke of coconut shell has functional properties as bioflavor,
preservative, and chelating agent, because it contains the active compounds of
phenol, carbonyl, and acid. But the used of liquid smoke as chelating agent has
not been developed. A study on chelation of heavy metal Pb by coconut shell
liquid smoke on soybean seeds has been conducted. The aimed of the study was to
evaluate the effectiveness of liquid smoke in the reducing heavy metals Pb in
soybean seeds, evaluate the change in the components of the liquid smoke was
used for chelation heavy metals Pb, and evaluate the influence of the phenol,
carbonyl, and acid components in the chelation heavy metals Pb in soybean seeds.
Liquid smoke of coconut shell pyrolysis has a specific gravity of 1.01
g/ml, pH 1.81, phenol 1.20% , carbonyl 5.75%, and acid compounds 8.40%.
