Study on Formaldehyde Migration Rules in Products of Tripolycyanamide for Food Packaging

Abstract:

In this work we studied the migration amount of formaldehyde in products of tripolycyanamide for food packaging. In order to review the rule of products of tripolycyanamide for food packaging, with different stimulant solutions, simulated temperatures and soaking time, the migration quantities of formaldehyde in products of tripolycyanamide for food packaging into deionized water, 3% acetic acid and 15% ethanol were measured by phenylhydrazine hydrochloride spectrophotometry. The amounts of formaldehyde migrated to 3 % acetic acid was higher than those of 15 % ethanol. Espousing in higher temperature , amount of formaldehyde of the products of tripolycyanamide were migrated more. And the total migrations of formaldehyde in three exposures was beyond the EU specific migration limits for formaldehyde (15 mg/L ).With the higher temperature exposure was done , the amount of formaldehyde migration reaches maximum in lower number of repeated exposures. We also discussed the formaldehyde migration rule for different surface roughness of food packaging materials.
