| Near infrared hyperspectral imaging (NIR-HSI) is a method that can be used to evaluate quality of fruit nondestructively. The objective of this research was to study the feasibility of NIR-HSI reflectance mode, within the wavelength of 935-1720 nm, for predicting quality of longans. The two important factors chosen were: total soluble solids (TSS) and moisture content (MC). Each longan was assessed by first measuring its spectral data then measuring its TSS and MC to establish calibration models using multiple linear regression (MLR) compared with partial least squares regression (PLSR). Original spectra of longans gave the optimum results by PLSR for developing the models with correlation coefficients (Rp) of 0.76 for TSS and 0.88 for MC as well as root... |

| Potato is one of the most important agricultural products that has great nutritional and industrial value. Potato seed tubers are usually used for growing this crop, but separating the seed tubers from the edible ones is tedious, time consuming and costly process. Therefore, a rotating potato sorting machine was designed, developed and evaluated in this research. This machine was able to sort potato tubers according to their size. Effects of sieves slope angle and rotational speed on the tubers mechanical damage, sorting accuracy and capacity of designed machine were evaluated. The test was conducted in the factorial experiment format with three replications based on a completely randomized experimental design. Three levels of sieves slope angle (5, 10 and... |

| Additives can reduce gaseous emissions from swine waste lagoons and pits. We have demonstrated for the first time that an additive has the potential to reduce methane emission from an anaerobic swine lagoon. ManureMax®, a humate product was evaluated for its ability to reduce gas and odor emissions from swine anaerobic lagoon and barn flush-water. Four treatments, Control (no additive), Low (label dosage), Medium (50% higher than label dosage), and High (200% higher than label dosage) were applied to inclined pipes installed in a swine lagoon. While the Medium and High treatments were not effective, the Low treatment reduced methane, 2-butanone, and tetrahydrofuran concentrations by 34%, 44%, and 57%, respectively vs. the Control in the pipe headspace.... |

| Most agricultural materials undergo various forms of preservation in order to enhance shelf life. Sheanut is usually preserved by heating the kernels over fire in a pot for a time period. This affects its properties especially during heat processing. It is expected that this work will provide information that would help optimize such processing. Preserved sheanut kernel samples sourced locally were prepared by manually cleaning, sorting, grinding and sieving to obtain desired particle sizes. The specific heat of the samples were evaluated as a function of particle size (2.36 mm), (1.18 mm and 1.00 mm), moisture content (initial moisture content, 10%, 20%, 30% and 40% db) and temperature (50oC, 60oC, 70oC, 80oC, and 90oC). The specific heat of each particle... |
