Development and Evaluation of Models for Predicting Chemical Contaminant Migration in Foods
Abstract
141 words
Polyethylene bags have become very popular for wrapping
ready food or during cooking. Polythene materials are known
to contain a wide range of potential migrants such as residues
from the polymerisation process, degradation compounds and
additives, many of which are toxic. There is need therefore to
assess the potential danger posed to humans by migration of
chemicals from polyethylene. Analysis of migrants in food is
expensive and time consuming because of low concentrations
of migrated substances and the complexity of the food matrix.
Therefore, dependable models that accurately predict the
progress of chemical contaminant migration in food is needed.
This research therefore aims to develop, simulate and validate
models capable of predicting the migration of chemical
contaminants by identifying and, quantifying plastic bag
contaminants so as to contribute to understanding of
contaminant migration, organoleptic changes, contaminant
diffusion and dispersion in “posho”
