Intermediate moisture foods (IMF) are shelf-stable products that have water activities of 0.6-0.85, with a moisture content ranging from 15% - 40% and are edible without rehydration. [1] These food products are below the minimum water activity for most bacteria (0.90), but are susceptible to yeast and mold growth .
Water activity values can also help limit moisture migration within a food product made with different ingredients. If raisins of a higher water activity are packaged with bran flakes of a lower water activity, the water from the raisins migrates to the bran flakes over time, making the raisins hard and the bran flakes soggy.
Pastirma is classified as an "intermediate moisture food". Lowering the moisture level is a form of food preservation that hinders the growth of microorganisms , and the cemen paste "is used to control surface mold growth during storage". [ 31 ]
The foods have been produced in collaboration with Japanese food companies such as Ajinomoto, Meiji Dairies, and Nissin Foods. [ 55 ] Korean : In April 2008, South Korea 's first astronaut, Yi So-yeon , was a crew member on the International Space Station and brought a modified version of Korea's national dish, kimchi .
Most extrusion processes for food processing are carried out at low to intermediate moisture (moisture level below 40%). High-moisture extrusion is known as wet extrusion , but it was not used much before the introduction of twin screw extruders (TSE), which have a more efficient conveying capability.
