“…Similar results were reported by Hassan et al. (2016) for small and big sized Spunta potato tubers stored at low temperatures of 8–13°C and RH 75%–82% and 85%–92%, respectively. However, the authors noticed a significant increase in soluble solids content of potato tubers stored at room temperature.…”

“…Soluble solids varied significantly among the majority of the tested potato genotypes but not between fresh and stored tubers, except for Naima, which showed significant (p < 0.05) increase by approximately 25.5%.

“…It seems that cold storage at 8°C inhibited the respiration rate and sprouting, which leads to reduce the consumption of accumulated sugars in stored tubers. Whereas, the higher soluble solid content might be linked to the converted starch into sugar induced by high temperature and high respiration rate (Hassan et al., 2016).…”

Potato (Solanum tuberosum L.) is a staple food widely consumed in Tunisia and represents a source of various secondary metabolites with human health benefits. However, cold storage of potato tuber affects their bioactive properties and functional quality. Despite the importance of this fact, few studies have examined the effects of extended cold storage on potato tubers quality. Therefore, the objective of the present work was to evaluate the effect of cold storage on the main quality traits of different potato genotypes grown in Tunisia. This investigation focused on four cultivated potato varieties including three commercial (Selena, Elbeidha, and Naima) and a selected clone CL27 grown under late cropping season conditions with planting at the beginning of autumn and a winter tuberization. The tubers from this trial were stored for 90 days at 8°C. The results obtained showed that quality traits of potato tubers were strongly influenced by storage at 8°C throughout 90 days. Additionally, disregarding the genotype, total carotenoids, phenolics, and flavonoids contents increased significantly following 90 days storage at 8°C. However, genotypic differences underlying the antioxidant activity in both hydrophilic and lipophilic fractions were detected suggesting their sensibility to cold storage. This study might be useful for breeders working on potato genotypes suitable for extended storage duration and for growers storing their material for extended period under low temperature.

“…Apart from biological and chemical methods of crop protection during storage, physical methods can also be used to improve tuber condition (Kasyanov et al 2013, Pietruszewski and Martínez 2015, Jakubowski et al 2016. Biochemical transformations occurring during storage in potato tubers exposed to UV-C irradiation were investigated by Hassan et al (2016).…”

Ultraviolet radiation in the C band to limit storage losses of potato was applied. Six edible potato varieties, viz., Lord, Vineta, Owacja, Ditta, Finezja and Tajfun were used as test materials. UV-C radiation was emitted from a 15 W radiator. The wavelength of the light used to irradiate potato tubers was 253,7 nm and the power density from 80 to 100 μW/cm2. The method of reduction of storage losses of potato tubers, based on their exposure to UV-C irradiation, can complement the presently used methods of potato crop protection during long-term storage.

“…Meteorological conditions during the vegetation season, genetic characteristics of varieties, and mechanical damage to tubers caused during harvesting and post-harvest treatment may also be responsible for natural losses of the potato tubers [44][45][46][47][48][49]. Several researchers [50][51][52] recommend using physical methods to improve crop condition during the storage alongside the biological and chemical methods of protection. Various systems using the UV-C light exposure have appeared in the literature for crops other than potatoes [53,54].…”

The purpose of the study was to establish whether UV-C radiation applied to potato tubers prior to their storage affected their natural losses over a long period of time. A custom-built UV-C radiation stand constructed for the purpose of this experiment was equipped with a UV-C NBV15 radiator generating a 253.7 nm long wave with power density of 80 to 100 μW∙cm−2. Three varieties of edible medium late potatoes, Jelly, Syrena, and Fianna, were the objects of the research. The measurement of tightly controlled storage conditions was carried out over three seasons between 2016/2017 and 2018/2019, in a professional agricultural cold store with automated adjustment of interior microclimate parameters. The obtained data were processed using the variance analysis (α = 0.05). There was a statistically significant reduction in transpiration- and respiration-caused losses in the UV-C radiated potato tubers in comparison to those of the control sample. Additionally, the Jelly variety reacted to UV-C radiation demonstrating a reduction in sprout weight.
