“…The use of electron accelerators as source of radiation has technological advantages like higher throughput, wider flexibility and more potential to overcome public objections to radioactive isotopic sources (Supriya et al, 2012). Nevertheless, the irradiation efficacy is highly dependent on intrinsic factors of each food product, requiring continuous studies of exposure time (doses) and geometry (dose uniformity) (Belchior et al, 2007;Kim et al, 2007). The effects of radiation on chestnuts composition have been progressively studied, either using electron beam treatment (Carocho et al, 2012) or γ-irradiation (Antonio et al, 2012a).…”

The present chestnut (Castanea sativa Miller) commercialization dynamics, including distribution to novel markets, demands suitable conservation technologies. Irradiation has been considered a promising alternative to chemical fumigation (legally forbidden and harmful for human health and environment) or heat treatments (technological difficulties and low efficiency). Following previous studies on the effects of irradiation in different chemical parameters, the present work aims to perform an evaluation of the effects of electron beam and γ-irradiation on the triacylglycerol profiles of fresh and stored chestnuts. An analysis of variance with type III sums of squares was performed using the general linear model procedure. As classification technique, a linear discriminant analysis using the stepwise procedure was also applied. Independently of irradiation type, samples irradiated with higher doses showed higher modifications in triacylglycerol profiles. In fact, samples irradiated with 1 and 3 kGy were clearly separated from the remaining groups in the linear discriminant analysis. The obtained results highlight the potential of triacylglycerol profiles as indicators of chestnuts irradiation. However, irradiation might be recommended as a suitable method for chestnuts preservation.

A b s t r a c t. Numerical models of bean seeds cv. Złota Saxa and yellow lupine seeds cv. Juno were generated with the use of a 3D scanner, the geometric parameters of seeds were determined based on the models developed, and compared with the results of digital image analysis and micrometer measurements. Measurements of seed length, width and thickness performed with the use of a micrometer, 3D scanner and digital image analysis produced similar results that did not differ significantly at a = 0.05. The micrometer delivered the simplest and fastest measurements. The mean surface area of bean seeds cv. Złota Saxa and yellow lupine seeds cv. Juno, calculated with the use of mathematical formulas based on the results of micrometer measurements and digital image analysis, differed significantly from the mean surface area determined with a 3D scanner. No significant differences in seed volume were observed when this parameter was measured with a 3D scanner and determined with the use of mathematical formulas based on the results of digital image analysis and micrometer measurements. The only differences were noted when the volume of yellow lupine seeds cv. Juno was measured in a 25 ml liquid pycnometer.

“…Examples of its implementation include modeling heat transfer and moisture loss in bagged potatoes during cold storage (Chourasia & Goswami, 2007), modeling heat transfer of infrared heating on strawberries (Tanaka et al, 2007), predicting 3-D dose distribution of electron beam radiation treatment of complex foods (Kim et al, 2007), and simulating radiation distribution and inactivation in wastewater treatment (Crapulli et al, 2010;Elyasi et al, 2006). CFD modeling has proved to be a powerful engineering tool, providing an efficient and effective design solution.…”

The practical usage of UV-C to decontaminate fruits has been limited by the difficulty applying a uniform dose to complicated shapes. Simulation of UV-C radiation treatment was investigated in this study to find the optimal treatment conditions. A setup of strawberries being placed on a UV-transmittable film with radiation sources from the top and bottom was proposed. A 4-lamp model with a horizontal distance of 300 mm between the lamps was found to yield the most uniform dose distribution, with mean radiation intensity of 2.00 W m _ 2 . For this configuration, the treatment time required to achieve one log inactivation of Cladosporium cladosporioides and Penicillium digitatum spores were 3 min 46 s and 1 min 36 s, respectively. Radiation simulation in combination with the inactivation model has been shown to be a useful tool for the optimization of the UV-C inactivation process.
