critical moisture content

[′krid·ə·kəl ′mȯis·chər ‚kän·tent]
(chemical engineering)
The average moisture throughout a solid material being dried, its value being related to drying rate, thickness of material, and the factors that influence the movement of moisture within the solid.

This lower critical moisture content for biomass deposition in basal kernels was significantly correlated to their longer duration of grain filling ([r.sup.2] = 0.79; p < 0.001; Fig.
Although the primary difference was the critical moisture content at PM between positions, differences around 40 to 60% moisture content were also evident during grain filling, showing a different growth pattern.
They found that if they know and can control the critical moisture content, such physicochemical changes as the browning or caking of avocado products can be delayed when products are stored.
model showed critical moisture contents of 0.0145, 0.0124 and 0.0078 at 25 C, 35 C and 45 C, respectively.
Since thermal inactivation was found to be insignificant for temperatures at or below 30[degrees]C, which is above the maximum wet bulb temperature used in the drying experiments conducted here, it is only necessary to characterize thermal rate effects below the critical moisture content. For the experimental conditions studied here, drying rate was always observed to affect viability, however, no interaction parameters were implemented to model the cross-tolerance of drying rate and moisture content.
