Introduction

Formaldehyde (HCHO) and hexamethylenetetramine (C6H12N4) are chemical raw materials, can be used to make food contact materials and products. Formaldehyde monomer, hexamethylenetetramine (HMTA) and various formaldehyde oligomers may remain in the product, as the product and food contact And migrate to food. HMTA under certain conditions will decompose formaldehyde, the conversion of the chemical reaction is as follows. C6H12N4 + 6H2 → O 6HCHO + 4NH3 The dangers of formaldehyde on the human body are well known. Relevant laws and regulations have developed a formaldehyde migration limit for food, this standard provides a measure Determination of four food simulants in the amount of formaldehyde migration. As the migration of HMTA in food may decompose formaldehyde, the relevant regulations The migration of HMTA has also been made, the migration limit of formaldehyde. Therefore, this standard also provides the determination of including HMTA Formaldehyde generated by the decomposition of formaldehyde migration total amount of methods. Food contact materials polymer materials Determination of formaldehyde in food simulants Spectrophotometry

1 Scope

This standard specifies the method of determination of formaldehyde in food simulants. This standard applies to food contact with the polymer material formaldehyde (including hexamethylenetetramine conversion of formaldehyde) in four food simulations Determination of the amount of migration in water (3% acetic acid solution, 10% ethanol solution and olive oil).
