The sorption isotherm ( desorption and adsorption ) of okro fruit was determined at three temperatures of 300C,400C and 500C within the range of 1090% Relative humidity (RH). Thymol solution was placed inside the desiccators to prevent microbial growth, particularly at the relative humidity above 65%. Gravimetric method was used for the sorption isotherm where the reading and recording was take...

A technique to rapidly determine the moisture content of hard red winter wheat, Triticum aestivum L., independent of densityy is presented. The complex impedance of bulk samples at 1 and 10 MHz was used along with a density-independent function to predict moistures ranging from approximately 11 to 22% in samples with bulk densities ranging from 0.65 to 0.85 glcm^. Calibration was performed on w...

In this study the correlation between lag factor G and Page ́s mathematical model parameter n was developed. Using the newly developed correlation the presence of internal or external resistance to moisture transfer during thermal drying can be verified. As modeling tools Artificial neural networks (ANN) and Adaptive neuro-fuzzy inference system (ANFIS) were used. The best model for determinatio...

the potential of near infrared reflectance spectroscopy (nirs) as a fast method to predict the crude protein (cp) and moisture (m) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on partial least squares (pls) was evaluated. the coefficient of determination in calibration (r2c) and standard error of calibration (sec) were 0.95 and 1...

The most commonly used technique for water content determination is Karl-Fischer titration with electrometric detection, requiring specialized equipment. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a...

Reproducible flow properties for the thermoset molded resins are necessary to insure that the manufacturing conditions used, such as mold temperature, mold pressure and cure time, consistently yield a usable final product. Lot-to-lot variations in flow properties can result in material which does not mold properly and must be rejected. One quantity which can substantially influence thermoset fl...
