Migration Test

What is migration? Which products should it be done? What tests does it cover?

With the growth of the ready-made food industry in recent years, the packaging materials used in the preservation of food have also gained importance. The packaging materials used should not contain toxic substances such as heavy metals, phthalates and BPA.

Migration test is one of the most important analyzes made in determining the damages of packaging materials for human health.

What is Migration? What is the Migration Test?

Migration test; These are the analyzes carried out on packaging, kitchen materials and food production machines that are in contact with food and enable the migration of substances that pose toxicological risks to food.

Factors affecting migration tests are as follows:

- Food structure
- Contact time
- Contact temperature
- The structure of the packaging and the amount of substance used in its content

Laboratories performing migration tests; It tests packaging materials in accordance with appropriate standards and methods, considering all these factors.

Migration tests are performed as total migration and specific migration.

Total migration is expressed as the sum of all substances that can pass from food contact materials to food.

Food simulations used in total migration tests are as follows.

Food-Like A	Aqueous Food, 10% Ethyl Alcohol
Food-Like B	Acid Food, 3% Acetic Acid
Food-Like C	Alcoholic Food, 20% Ethyl Alcohol
Food-Like D1	Fatty Food, 50% Ethyl Alcohol
Food-Like D2	Fatty Food, Vegetable Oil
Food-Like D2	Replaced 95% Ethyl Alcohol
Food-Like D2	Replaces Isooctane
Food-Like E	Dry Food, Tenax

Specific migration is based on toxicological studies applied to a particular substance in food simulations.

Analyzes performed within the scope of specific migration analyzes;

Heavy Metal Determination

Bisphenol A (BPA) Determination

Determination of Epoxy and Its Derivatives

Determination of Phthalate

Determination of Primary Aromatic Amine

The said migration analysis is an important and mandatory quality criterion in the packaging industry. Packaging materials, whose main task is to protect the food product, which appeals to our eyes, should not contain heavy metals and toxic substances that threaten human health.
