“…The studied sample of wheat is within the Mexican Standard for moisture content and density (marked as maximum 13 % and minimum 760 kg/m 3 for moisture content and density, respectively, by NMX-FF-036NMX-FF-036 1996). Additionally, the characteristics of barley, corn, sorghum and wheat are similar to those reported for the same cereals by Nelson and Trabelsi (2011) and for wheat reported by Soltani and Alimardani (2014).…”

Dielectric properties of barley, corn (white and yellow), sorghum, and wheat at microwave frequencies for heating purpose were analyzed. Properties were determined at 915, 2450 and 5800 MHz with the free space transmission method in the cereals at 20, 30, 40, 50 and 60°C. ε´and εBof all the cereals decreased with increasing frequency. ε´slightly increased with temperature, while ε Bremained practically constant for all the cereals in the temperature range from 20 to 60°C. Penetration depth decreased with increasing frequency for all the samples, and increased with increasing temperature at 915 MHz, except for barley. These results are useful for further microwave heating applications for the studies on cereals.

“…The correlation results in table 2 showed that all three grain samples, phase shift was statistically correlated with grain mass. Dielectric constant (ε') and loss factor (ε") were both correlated with grain mass at fairly low level but correlated with moisture content at high level, which meant both ε' and ε" were valid indicators to reflect moisture variations in the estimation model (Soltani and Alimardani 2014;Trabelsi et al, 2016).…”

HighlightsRadio frequency sensing technology was used to estimate clean grain mass based on grain moisture content and grain properties.Multiple variable regression analysis was used to develop grain mass estimation model.A grain mass estimation model with high R2 was developed by introducing dielectric properties and phase angle.Parameter of dielectric constant e' indicated the domination of moisture content in grain mass estimation model.Abstract. Grain mass estimation is critical in many precision agriculture applications, especially in yield monitoring during harvest procedures. A new clean grain mass estimation method using Radio Frequency (RF) sensing technology is discussed in this paper. RF sensing technology is sensitive to moisture content and grain properties. In this study, a vector network analyzer (VNA) and a pair of horn antennas were used to collect phase shift and attenuation data from 1 to 18 GHz of grain samples (soybean, canola, and corn) on a static testbed in an anechoic chamber. Using multiple variable linear regression analysis, a comprehensive clean grain mass estimation model was developed based on the dielectric properties of the grain samples derived from the S-Parameters at 13 GHz. Dielectric (e') constant/properties and phase shift were introduced into the regression models and generated a grain mass estimation result with R2 values of 0.976, 0.977, and 0.989 for soybean, canola, and corn samples, respectively. The results indicate that RF sensing technology can reveal how grain attributes interact with electromagnetic fields at a certain frequency and has the potential to provide more accurate sensing methods for estimating grain mass in multiple precision agricultural applications.

“…For estimating the moisture content, reduction in the mass of the films is observed when it is exposed to the 100ºC.The net variation between initial and final moisture content of the film provide statistics about the moisture content, according to the formula used by Soltani et al (2014) …”

Edible films of pectin and whey protein containing antimicrobials i.e. Cinnamic acid, Cinnamon leaf essential oil and Cinnamon bark powder were developed and functionally characterized. The cinnamon essential oil showed significant antimicrobial activity against the common food borne pathogens viz. Escherichia coli, Staphylococcus aureus and Listeria monocytogenes. The edible films were further structurally characterized for the transparency of visible and UV light, functional group characterization using FTIR analysis and determination of total moisture content. Antimicrobial activity of these films made from the edible source and cinnamon essential oil were further examined toward the associated food contaminants such as E. coli, L. monocytogenes and S. aureus. Edible films of pectin and whey showed significant level of antimicrobial potential against the food associated pathogens and could be used as a sustainable solution to the conventional packaging material specifically used in food processing.
