Quantifying Total Migrant from Food Contact Materials by The Residue After Evaporation Method

Product catalog summary
Introduction
Ensuring the safety of food contact materials (FCMs) involves determining the total migration of substances from the material into food. Total migration includes non-volatile substances such as monomers and additives that can transfer from materials like plastic packaging into food.
Residue After Evaporation Method
This method quantifies total migrants by evaporating a food simulant that has been in contact with the FCM. The residue left after evaporation represents the migrated substances. The process involves selecting an appropriate food simulant, exposing the FCM to it under controlled conditions, and then evaporating the simulant to measure the residue. The residue's weight is used to calculate the total migrant, which is compared to regulatory limits.
Equipment and Automation
Automation in this process is achieved using equipment like rotary evaporators and robotic systems, which enhance the accuracy and efficiency of residue measurement.
Labthink C830H Tester
The Labthink C830H Migration & Non-volatile-matter Content Tester is an advanced tool for determining migration and non-volatile matter contents. It supports fast evaporation and efficient reagent recycling, improving testing efficiency with various reagents.
Conclusion
Measuring residue after evaporation is a valuable method for assessing FCM safety and regulatory compliance. Despite some limitations, it provides essential information when combined with other analytical techniques. Labthink promotes collaboration with the packaging industry to enhance quality control.

Quantifying Total Migrant from Food Contact Materials by The Residue After Evaporation Method-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Quantifying Total Migrant from Food Contact Materials by The Residue After Evaporation Method One crucial aspect of ensuring the safety of food contact materials (FCMs) is determining the total amount of substances that can migrate from the FCM into food. Total migration refers to the overall quantity of non-volatile substances that transfer from a food contact material (like plastic packaging, a cooking utensil, or a storage container) into food. These migrating substances can include monomers, additives, or other compounds present in the FCM. Residue After Evaporation is one of the methods used to quantify the total migrant in food simulants liquid. The principle behind this method is straightforward: if substances migrate from the FCM into a food simulant, evaporating the simulant will leave behind a residue 1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 representing those migrated substances. By measuring this residue, we can quantify the total migrant. The testing process begins with selecting a food simulant that mimics the properties of the food the material will contact. The food contact material is then exposed to this simulant under carefully controlled conditions, including specific temperature and contact time. During this period, substances from the material migrate into the simulant. Next, the simulant is evaporated, leaving behind any migrated substances as a residue....
