Abstract

The invention discloses a method for detection of transfer volume of phthalic acid ester matters in a food package material, the method includes extraction, namely extraction of a food sample, to be more specific, water, acetonitrile, MgSO4 and sodium acetate are added into the food sample for eddying for 1 min and centrifuging for 2 min in 4000 r / min to obtain a liquid supernatant and a residue, the liquid supernatant is collected, and the residue is blew to dry with 40 DEG C nitrogen; purification, to be more specific, a PSA purification packing, a C18 purification packing and MgSO4are added for eddying for 1 min and centrifuging for 2 min in 4000 r / min, and the liquid supernatant is taken; and determination, to be more specific, gas chromatography and liquid chromatography are used for analyzing to detect the content of the phthalic acid ester matters in the food sample. The present invention provides a reliable, convenient and accurate method for detection of transfer volume of the phthalic acid ester matters in a contact package material.

Description

technical field

[0001] The invention relates to a detection method for phthalates in food, in particular to a detection method for the migration and contamination of phthalates in food contact packaging materials. Background technique

[0002] Food packaging materials, especially plasticizer phthalates in plastic packaging materials, can migrate and dissolve into food under certain conditions, enter the human body through diet, skin contact, etc., and may pass through the placenta or Milk produces transgenerational effects. Animal experiments show that phthalates have little acute toxicity, but in large doses, they have different degrees of teratogenic, carcinogenic and mutagenic effects on animals. Its subacute toxicity mainly manifests as damage to the kidney, liver, and testis, affecting reproductive function, and inhibiting sperm formation.

[0003] EU Directive 2002 / 72 / EC and its subsequent amendments 2004 / 19 / EC and 2005 / 79 / EC stipulate a list of approved plastic raw ...
