Method for determining migration quantity of volatile organic compounds in adhesive sticker for food label in water-based food simulating object

Abstract

The invention discloses a method for determining the migration quantity of volatile organic compounds in an adhesive sticker for a food label in a water-based food simulating object. The method comprises the following steps: performing a direct or indirect migration test on the adhesive sticker for the food label through a water-based food simulating solution; sampling the water-based food simulating solution through purging and trapping; separating 10 volatile organic compounds through HP-5ms or chromatographic columns with similar properties; performing detection through a mass spectrometry detector; performing quantification through an external standard method, wherein the 10 volatile organic compounds include nonene, 2-ethylhexanol, 1,2,4,5-tetramethylbenzene, camphor, 1-dodecene, naphthalene, 2-ethylhexyl acrylate, 1-methylnaphthalene, 1-undecanol and dodecyl aldehyde. The method is accurate in test, easy to operate, high in efficiency, quick, high in sensitivity and high in practicality, is applicable to qualitative and quantitative determination on the volatile organic compounds in the adhesive sticker for the food label through a manufacturing enterprise of the adhesive sticker for the food label and relevant government supervision departments, and can be used for avoiding harm to the physical health of a consumer caused by over-large migration quantity of the volatile organic compounds.

Description

technical field [0001] The invention relates to a method for measuring the migration amount of volatile organic compounds in food label self-adhesives in water-based food simulants. Background technique [0002] Self-adhesive labels are also called self-adhesive labels, instant stickers, sticky notes, pressure-sensitive paper, etc. The basic structure of self-adhesive labels is from top to bottom in order of surface coating, surface material, primer, adhesive, silicon coating Layer, backing paper and back coating composition. Among them, the part that is in direct or indirect contact with food is the adhesive, and its main component is rubber-based, elastomer or acrylic adhesive. [0003] Self-adhesive labels are used as food labels and can be seen everywhere, especially in large supermarkets. Whether it is fish and shrimp, fresh meat, or cold dishes, fruits and vegetables, labels on transparent packaging bags or plastic wrap are the only way to check out. Due to direc...

AI Technical Summary

Problems solved by technology

Due to direct or indirect contact with food, the safety of self-adhesive food labels is closely related to the health of consumers. However, there are currently no relevant laws and regulations at home and abroad for the use of self-adhesive food label adhesives. The risk analysis of self-adhesive food labels is basically blank

There is currently no quantitative method to assess the migration of harmful VOCs from self-adhesive labels into food, especially water-based food
