Called ISO 7304-2, the standard is suitable for spaghetti and macaroni made from durum wheat. It assesses quality of cooked pasta in terms of starch release and “liveliness and firmness” – otherwise known as texture.
The cooking has to be repeated until a continuous white line in the centre of the crushed strand or crushed section disappears.
The standard is said to complete another standard published in 1985, IS 7304-1, which is used to estimate cooking quality of spaghetti.
