STM3163 Migration and Food Package Interactions Quiz

What is the concern related to migration and food-package interactions?

• Movement of large fragments

• Biological food spoilage due to microbial contamination by the package

• Corrosion of metal containers

• Harmful chemical compounds transferring from package to food

What is the term used for the migration of chemical compounds from food to the package?

• Diffusional mobility

• Volatile system

• Leaching

• Scalping

Which factor does not affect the diffusional mobility of potential migrants in the package?

• Temperature

• Time

• Molecular mass

• Chemical affinity with the food

What is the main concern regarding chemicals from plastics in food packaging?

• Formation of carcinogenic substances

• Loss of desirable food flavors

• Corrosion of metal containers

• Food spoilage due to microbial contamination

Which material is currently approved for use as a functional barrier in food packaging according to EU regulations?

• Aluminum

• Paper

• Plastic

• Glass

Main concern related to the use of recycled plastics in food packaging?

• Migration of chemical contaminants

• Formation of carcinogenic substances

• Loss of desirable food flavors

• Corrosion of metal containers

Term used to describe the unwanted odors or flavors imparted to food through external sources?

• Off-flavors

• Scalping

• Taint

• Sorption

compound CANNOT taint packed foods in flexible packaging materials?

• Coating and varnishes
