Daftar Isi:
- 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%. Soybean seeds soaked in coconut shell liquid smoke with various concentration of 0% (control/aquademineralisa)
