Description
Technical field
The utility model is related to food contact material detection field, more particularly to a kind of packing timber for dry food
The device of Special migration test in material.
Background technology
Food contact material refers to the material for during normal use having contact with food, refers to and is directly or indirectly connect with food
Tactile material and product, is related to packaging for foodstuff, tableware, kitchen tools, food processing apparatus etc., and packaging material for food is wherein most heavy
Will, most common and most typical food contact material.Food contact material contains during being contacted with food in material
Chemical composition may be migrated and taken in by human body into food, the food-safety problem that generation is detrimental to health.European Union, U.S.
State, China have progressively formulated on food contact material specific to property rule and standard in recent years, in packaging material
Material transport amount carries out management and control, and project must be surveyed by what packaging material for food was listed in the migration of packaging material predetermined substance in.It is specific to move
It is the important indicator for restricted substances are carried out with management and control foundation in each regulation, standard to move limitation, and in new material, novel substance
Safety evaluation research process in play an important role.According to the way of contact of food and packaging material, migration can be divided into directly
Connect migration and indirectly two classes of migration.Direct Transfer such as with chemical substance moving to biscuit in the packaging bag of biscuit directly contact
Move, and migrate then such as with biscuit the migration of chemical substance in the packing box outside the biscuit bag without directly contact to biscuit indirectly,
Migration is again comprising contact migration and gas-migration both of which indirectly.
According to food variety, food can be generally divided into aqueous food, ethanol food, oily food, dry food etc., do
