TRANSPORT CONSIDERATIONS OF POTENTIAL MIGRANTS FROM FOOD PACKAGING MATERIALS
Migration from polymeric packaging materials to containd foods is essentially a desorption process involving low molecular weight species in a polymeric matrix. Such desorption can affect both intrinsic quality and safety of ingested packaged food. A legalistic problem also exists because of present...

TRANSPORT CONSIDERATIONS OF POTENTIAL MIGRANTS FROM FOOD PACKAGING MATERIALS |
| abstract |
Migration from polymeric packaging materials to containd foods is essentially a desorption process involving low molecular weight species in a polymeric matrix. Such desorption can affect both intrinsic quality and safety of ingested packaged food. A legalistic problem also exists because of present regulations of “zero tolerance” where a possible migrant is a potential carcinogen. The precise elucidation of desorption, at extremely low levels of initial migrant concentration, has thus become a major issue. However, desorption at such levels has not been adequately studied.Sorption/desorption studies conducted with food simulating solvents and foods in classical phase distribution systems shows marked concentration dependence for certain poly (vinyl chloride) resins. The thermodynamic relations between selected monomer/polymer systems have been further studied by inverse phase gas chromatography for both poly (vinyl chloride) and poly (acrylonitrile) and some of its copolymers. Results from these studies suggest that entropic relations are dominant at such low levels for transport. |

Such desorption can affect both intrinsic quality and safety of ingested packaged food. A legalistic problem also exists because of present regulations of “zero tolerance” where a possible migrant is a potential carcinogen. The precise elucidation of desorption, at extremely low levels of initial migrant concentration, has thus become a major issue. However, desorption at such levels has not been adequately studied.Sorption/desorption studies conducted with food simulating solvents and foods in classical phase distribution systems shows marked concentration dependence for certain poly (vinyl chloride) resins. The thermodynamic relations between selected monomer/polymer systems have been further studied by inverse phase gas chromatography for both poly (vinyl chloride) and poly (acrylonitrile) and some of its copolymers. Results from these studies suggest that entropic relations are dominant at such low levels for transport.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2007</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2007||||||||||</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">MILTZ, J.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">GIACIN, J.
