A weaker flour, such as a cake or pastry flour with a much lower gluten content would have a much steeper decline after peak time. The points of interest on the graph are fivefold: Arrival Time (Absorption) – Absorption is the point chosen by the baking industry which represents a target water to flour ratio in bread.
The moisture content of grains is an essential property in food storage. The moisture content that is safe for long-term storage is 12% for corn, sorghum, rice and wheat and 11% for soybean [ 1 ] At a constant relative humidity of air, the EMC will drop by about 0.5% for every increase of 10 °C air temperature.
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 .
The relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given temperature. If the composition or quality of the material changes, then ...

Meat water holding capacity (WHC) refers to the ability of meat to retain moisture including moisture inherent to the muscle tissue and any fluids that may be added to the meat during processing. [ 1 ] [ 2 ] The WHC characteristic corresponds to meat juiciness and meat tenderness .
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.
