A Review of Hygroscopic Equilibrium Studies Applied to Rice

Transactions of the ASABE, 2010
Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH-measurement methods.

HYGROSCOPIC EQUILIBRIUM OF SUNFLOWERSEED, FLAXSEED, AND SOYBEANS

Canadian Journal of Research, 1944
Equilibrium moisture values for relative humidities of from 31 to 93% were obtained for sunflowerseed, flaxseed, and soybeans. The hygroscopicity of whole sunflowerseed per se is practically the same as that of flaxseed, that of dehulled sunflowerseed is somewhat lower.

Simultaneous Analysis of the Equilibrium Hygroscopicity and Water Transport Kinetics of Liquid Aerosol

Analytical Chemistry, 2013
We demonstrate that the equilibrium hygroscopic response of an aerosol droplet and the kinetics of water condensation and evaporation can be retrieved with high accuracy, even close to saturation, through comparative measurements of probe and sample aerosol droplets.

30—HEAT AND MOISTURE EXCHANGE IN WOOL BEDS: EQUILIBRIUM THEORY IN THE HYGROSCOPIC RANGE

The Journal of The Textile Institute, 1972
Cassie's theory of propagation of heat and moisture changes in beds of wool fibres is re-examined by means of the method of characteristics. Substantial differences result in the predictions of the theory by treating the coefficients of the pertinent differential equations as functions of the dependent variables rather than as constants.

Universal Approximation Formulas of Curvature Correction and Equilibrium Sizes of Hygroscopic Particles

Journal of Applied Meteorology, 1996
Theoretical analysis shows that when water activity is larger than its threshold value and the dry radius of a particle is larger than 0.005 μm, the deviation of curvature correction from unity can be accurately represented by the product of two terms, with one term strongly depending upon water activity and the other depending upon dry radius ...

Hygroscopic equilibrium of microencapsulated extract of passion fruit seed and its effect on the antioxidant capacity

Journal of Food Process Engineering, 2017
AbstractThe hygroscopic behavior of microcapsules of antioxidant extract of defatted passion fruit seed, produced using spray drying technique, was analyzed at 20 and 40 °C by the static method with saturated saline solutions. The isosteric heat of sorption of the microcapsules, concentration of phenolic compounds and piceatannol, and the antioxidant ...

Investigation of hygroscopic equilibrium and modeling sorption isotherms of the argan products: A comparative study of leaves, pulps, and fruits

Food and Bioproducts Processing, 2019
Abstract The aim behind this work is to demonstrate and validate a predictive experimental model of the thermophysical behaviors of the three argan products, leaves, pulps and fruits, using the experimental determination of sorption isotherms. They constitute an important information source to establish the stability of the products of argan and ...

Behavior of Moisture Gain and Equilibrium Moisture Contents (EMC) of Various Drug Substances and Correlation with Compendial Information on Hygroscopicity and Loss on Drying

Pharmaceutical Development and Technology, 2005
The behavior of moisture gain and equilibrium moisture content (EMC) was determined for 30 drug substances at relative humidities (RH) ranging from 11% to 93%. Based on the results, the drugs were categorized into different classes, following the classification system proposed by Callahan et al.

HYGROSCOPIC EQUILIBRIUM AND TEXTURE OF FREEZE-DRIED FOODS

1967
Abstract : Improved methodology for the objective evaluation of food texture was applied to the measurement of the textural parameters of special freeze-dried foods which were storage-equilibrated under different relative humidity conditions. The foods included pre-cooked freeze-dried beef, laminated freeze- dried products in the form of bite-size ...

Effects of Non-Equilibrium Hygroscopic Growth of (NH₄)₂SO₄ on Dry Deposition to Water Surfaces

Environmental Science & Technology, 1998
Growth of hygroscopic aerosols near water surfaces is believed to enhance dry deposition rates, which are a strong function of particle size. Previous dry deposition models estimate hygroscopic growth by assuming equilibrium between aerosols and water vapor (Williams, R. M. Atmos. Environ. 1982, 16, 1933-1938).
