Food scraping is a term used to describe the process of removing food particles from surfaces. It is often done in restaurants and other food service establishments to ensure that all surfaces are clean and free of any food debris. The term ORT is an acronym for 'Organic Residue Test' which is a test used to measure the amount of organic material present on a surface. This test is often used to determine if a surface has been properly cleaned and is free of any food particles.
