“…At extreme dosage both amylose and amylopectin molecules are depolymerized and thus the starch shows the decreased amylose content [54,55]. Tubers exposed to 150 Gy and stored at +24 °С for 35 days showed the starch content at the level of the untreated control [51]. Lu et al [53] showed that starch content significantly decreased in two studied cultivars irradiated at 100 Gy and stored at +8 °С for 5 months.…”

“…At higher gamma irradiation doses the cell wall and membrane are disrupted; rot development, water loss, skin and flesh darkening, bud blackening and tuber softening are observed. In most studies the destructive processes are shown at doses higher than 1 kGy [44,50,51]. Apparently, 500 Gy is the highest acceptable (threshold) dose and depends on the cultivar and tuber condition [46,47].…”

Potato is an important staple food crop. Potato tubers require proper treatment before planting and after harvest to produce high yields and avoid storage losses. Among different techniques of potato treatment physical methods are of special interest: thermal treatment using hot water and steam, ultraviolet (including continuous-wave UV using pulsed Xe-lamps) and gamma-irradiation, treatment with magnetic and electromagnetic fields (including microwaves). The majority of physical methods is environmentally friendly and can be applied without special registration and in the developing countries. In the present paper, for the first time, the scientific papers on physical methods of potato treatment for the last 35 years are comprehensively reviewed. The review demonstrates that such an approach is perspective both for pre-planting and postharvest treatment of potato. Physical treatment affects biochemical, cellular and physiological status of potato. Methods of physical treatment enable to control phytopathogens, and some methods (ultraviolet and gamma-radiation) even are capable of improving immunity of plants. The main traits of potato tubers that can be influenced by physical treatment are sprouting (stimulation or inhibition), susceptibility to rot and black leg diseases, and starch, reducing sugars and ascorbic acid contents. The tuber response to physical treatment depends on dosage and date of treatment, duration and temperature of storage, agricultural technology and cultivar. Low doses of treatment may be inefficient while too high dosage may result in cell deterioration or death and poor immunity, and eventually to disease development. Too early treatment may damage a tuber since it should pass through suberization (wound healing) after harvest; too late treatment requires higher doses. The proper adjustment of treatment is necessary for cultivar and individual storage conditions.

“…Otros estudios en la variedad "Ágata", almacenada por 35 días a 21 °C y 39% de HR, reportaron 0.15 kGy como la mejor dosis para reducir pérdidas postcosecha [24]. Para el caso de la variedad chaucha amarilla, Zavala [25] evaluó los efectos de diferentes dosis de radiación gamma (0.025; 0.050; 0.075 y 0.10 kGy) sobre la expresión fenotípica; la dosis de 0.050 kGy indujo el retraso en la brotación y existieron cambios morfológicos en la coloración y forma de hojas y flores.…”

Solanum phureja es una variedad andina de papa con un alto potencial de exportación, gracias a sus propiedades nutricionales, organolépticas y funcionales; sin embargo, su tiempo de vida en percha es muy reducido. Esta investigación tuvo como objetivo evaluar el tratamiento de este tubérculo con radiación gamma para retardar la brotación. Se empleó un diseño factorial 4×2 para seleccionar la mejor combinación de dosis (0, 80, 120 o 160 Gy) y tiempo después de la cosecha (uno o cinco días) del tratamiento. Asimismo, se utilizó un diseño factorial 3×2 para seleccionar la mejor combinación de dosis de clorprofam (CIPC) (0, 20 o 30 mg kg-1) y tiempo después de la cosecha (uno o cinco días); este es un tratamiento químico común para retrasar la germinación de la papa. El mejor tratamiento físico correspondió a la irradiación con una dosis de 120 Gy, cinco días después de la cosecha; produjo una pérdida de peso de 16.5%, una pérdida de firmeza de 17.2%, ausencia de brotes y 4.0% de pudrición después de 40 días de almacenamiento a 19 ° C y 60% de humedad relativa. El mejor tratamiento químico correspondió a la aplicación de 30 mg de CIPC kg-1 a los cinco días de la cosecha, y produjo una pérdida de peso del 17,4%, una pérdida de firmeza del 21,0 %, un 8,0% de podredumbre y la aparición de brotes después de 25 días. En las papas de la muestra control (sin ningún tratamiento), la pérdida de peso fue del 23,7%, la pérdida de firmeza del 20,9%, la pudrición del 7,0% y la aparición de brotes a los 6 días. Los análisis sensoriales (apariencia, color, textura y flavor) y proximal (contenido de humedad, cenizas, proteína, extracto etéreo, fibra cruda y carbohidratos totales) revelaron que los tratamientos aplicados no afectaron significativamente las características organolépticas y nutricionales de las papas. Estos resultados sugieren que la irradiación de chaucha amarilla permite incrementar su vida útil en aproximadamente 33 días, conservando su calidad.

“…Various methods of drying potatoes have been carried out by farmers and researchers, in general potato, farmers do drying with conventional methods by utilizing sunlight heat [6]. Another method is to use ohmic heating to save 88% more than conventional methods, but this method requires considerable time [7]. Potato drying can also use the irradiation method using Co-60 sources [8].…”

Drying of Electrohydrodynamic (Ehd) on Potato Slices (Solanum Tuberosum) with Electrode Distance Variation

This research is about the use of electrohydrodynamics (EHD) on potato slices. The purpose of this study was to circumvent potato slices by comparing the results of variations in distance between the two electrodes. EHD generation is carried out using two types of electrode geometries, namely the needle electrode and the concentric ring electrode. Needle electrodes as cathodes and field electrodes or concentric rings as anode electrodes. The two electrodes are 10 x 10 pieces each. Drying the potato slices is carried out by placing it in a sample location parallel to the concentric ring electrode. Drying with EHD in atmospheric conditions will produce a current when given the added voltage measured on an digital multimeter. Electrode distance variations are 4 mm, 6 mm, 8 mm, 10 mm and 12 mm. After drying, drying rate, shrinkage, moisture content was measured which showed a decrease with increasing distance between electrodes, while energy efficiency increased with increasing distance between electrodes. The greater the distance between the electrodes for drying the potato slices, the smaller the shrinkage and water content decreases in the sample slices. 4 6 8 10 12 0 5 10 15 20 Energy Effeciency [ x 10 4 kJ/gram] Distance [mm]
