Migration of pentachlorophenol residue from spiked secondary paperboard packaging to edible gelatin

Abstract

The consumer exposure to the new harmful substances with origin in packaging which have contact with the food can occur as a result of their intentional migration or not incorporated in the food during the food chain. The paper and the cardboard are used in contact with dry food and that is because of this it is seen by the consumer as "healthy". Considering that the gelatin is too consumed by children and athletes and the wood from which the packaging are made suffer chemical procedures with the insecticide pentachlorophenol (PCP) for their preservation, studied the transference and the incorporation of PCP in the secondary packaging of the edible gelatin proving effectiveness from the barrier with polypropylene (PP) use as a primary packaging. The results indicate the migration with high temperature (60° C) in a short period of time (48h) when the secondary packaging was fortified with derivatised PCP into 0,01 mg L-1 concentration and put in contact with dry gelatin secured in polypropylene sachet. Others papers also point out the migration of chemical pollutants including chlorophenol and emphasize the importance of this research represent like a risk of sub-acute contamination.
