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 .
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 various types of food products manufactured by extrusion typically have a high starch content. [1] Directly expanded types include breakfast cereals and corn curls, and are made in high-temperature, low-moisture conditions under high shear. Unexpanded products include pasta, which is produced at intermediate moisture (about 40%) and low ...
The water in food has a tendency to evaporate, but the water vapor in the surrounding air has a tendency to condense into the food. When the two tendencies are in balance— and the air and food are stable—the air's relative humidity (expressed as a fraction instead of as a percentage) is taken to be the water activity, a w. Thus, water ...
Food moisture analysis is the determination of the concentration of water in a food sample. A variety of techniques may be used including Karl Fischer titration and loss on drying. Many technical standards exist which define test methods for determining moisture in different types of food.
Siblings—you can't live with them, but you can't live without them. Unless, of course, you're a 29-year-old horse forced to babysit your rambunctious younger sister!
"It Ends With Us" co-stars Justin Baldoni, pictured at "The Boys In The Boat" screening in New York City on Dec. 13, 2023, and Blake Lively, who appeared at their film's London premiere on Aug. 8 ...
When used as a food additive, a humectant has the effect of keeping moisture in the food. [1] Humectants are sometimes used as a component of antistatic coatings for plastics. A humectant attracts and retains the moisture in the air nearby via absorption, drawing the water vapor into or beneath the organism's or object's surface.
