Abstract
The objective of this study was to evaluate the storage potential of the Asterix, Challenger, Ludmila and Markies potato cultivars. Additionally, the study aimed to assess the effect of reconditioning during storage on the suitability of the studied cultivars for processing French fries. Potato tubers of the Asterix, Challenger, Ludmila and Markies were stored at 4°C and 8°C for 180 days. After 60 days of storage, they were reconditioned at a temperature of 14°C for a period of 15 days. At each evaluation period, the tubers were processed in an electric fryer at 180°C for 3 minutes and the visual color of the fries was assessed. The levels of reducing sugars and total soluble sugars were also analyzed. The levels of reducing and total sugars varied according to each cultivar and storage temperature. Storage of the cultivars Asterix, Challenger, Ludmila and Markies at 4°C increased the levels of total reducing and soluble sugars; Reconditioning after the storage period at 8°C contributed to the reduction of the levels of total reducing and soluble sugars; The cultivar Markies appears to be a good option for storage of potato tubers at 8°C.

Introduction
Potato production (Solanum tuberosum L.) in Brazil occurs year-round, to meet the demand for both fresh consumption and industrial processing. Therefore, the storage of potato tubers for later processing is rarely used in Brazil (BACARIN et al., 2005; FERREIRA et al., 2007); with producers typically storing seed potatoes for the next planting season.
With the increasing consumption of processed potatoes, particularly in fried form (ZORZELLA et al., 2003; ANDREU et al., 2007), storage has become an important factor. Due to the lack of high-quality raw materials in adequate quantities for the processing industry, the Brazilian market has been increasingly supplied by imports, mainly of pre-fried and frozen potatoes (VENDRUSCOLO; ZORZELLA, 2002). Proper tuber storage is crucial for maintaining the balance of potato supply in the market (BISOGNIN et al., 2008).
Low storage temperatures negatively impact potato quality due to increased sugar content (BURTON, 1989), leading to darkening during high-temperature processing (Maillard reaction), which makes the product commercially unacceptable (DAVIES; VIOLA, 1992). High levels of reducing sugars cause undesirable darkening of potatoes during frying, reducing their commercial acceptance (FERNANDES et al., 2010). Therefore, proper management during the storage period is essential.
The acceptance of potatoes for processing in the form of sticks or chips depends largely on the final product’s color. The most important factor influencing frying color is the reducing sugar content, as high levels result in darkened products (TALBURT et al., 1975), which are rejected by the consumers (MENÉNDEZ et al., 2002).
One of the methods used to reduce sugar content during potato storage at low temperatures is reconditioning. Potato tubers stored under low temperatures are exposed to a higher temperature for a period, reducing sugar levels. However, this process does not always lower sugar content, as the results depend on the tubers’ exposure time to cold and the response of each cultivar (BURTON, 1982).
The final quality of French fries’ potatoes depends, among other factors, on the cultivar used for processing. In Brazil, numerous potato cultivars are grown due to the country’s diverse climate and soil conditions. Cultivars vary in agronomic characteristics, such as high yield, adaptation to edaphoclimatic conditions, maturity period, and post-harvest quality. Therefore, the selection of raw materials for potato chip production requires special attention, as it directly influences the final product’s characteristics.
Thus, the objective of this study was to evaluate the storage potential of the Asterix, Challenger, Ludmila, and Markies’s potato cultivars. Additionally, the study aimed to assess the effect of reconditioning during storage on the suitability of these cultivars for potato French fries processing.
Materials and methods
Potato tubers of the Asterix, Challenger, Ludmila and Markies cultivars were harvested in October 2014 in the municipality of Perdizes, MG, and transported to the Post-Harvest Laboratory of the Federal University of Viçosa, MG. The tubers were selected, placed in plastic boxes covered with filter paper moistened daily with water, and subjected to a curing process. During curing, they were stored in a BOD incubator at 14°C for 15 days to allow for the formation of the wound periderm.
After the curing period, the BOD temperature was reduced by 1°C per day until reaching 8°C (KIBAR, 2012). Subsequently, the tubers were divided into two batches for each cultivar and transferred to cold storage chambers, where they were stored at 4°C and 8°C for 180 days. The relative humidity inside the chambers was maintained at 85%. Starting at 60 days of storage (60, 90, 120, and 150 days), the reconditioning process was initiated. Monthly, ten tubers of each cultivar were removed from cold storage at 4°C and 8°C and placed in a BOD incubator at 14°C for 15 days.
The experiments were arranged in a split-split plot design with five replications. Each experimental unit consisted of two tubers. The main plots were the cultivars, the subplots were the storage temperatures (4°C and 8°C), and the sub-subplots were the storage durations (0, 30, 60, 90, 120, 150, and 180 days) or the reconditioning periods (60, 90, 120, and 150 days). During the storage and reconditioning periods, the tubers were evaluated for color after frying and for soluble and total sugar content. Samples of ten tubers were collected for each cultivar and temperature during both storage and reconditioning. The tubers were cut into fries, fried in an electric fryer at 180°C for three minutes, and visually assessed after frying.
For sugar extraction, approximately 5 g of tuber pulp was weighed. Then, 80% ethanol at 70°C was added until the sample was fully submerged. The material was homogenized using a Polytron blender, transferred to Falcon tubes, and left to stand for 10 minutes. The samples were then centrifuged for 10 minutes at 2,000 g. The supernatant obtained from centrifugation was collected and transferred to a graduated cylinder. Next, 5 mL of 80% ethanol was added to the tube, followed by agitation and another 10-minute resting period before a second centrifugation. This process of ethanol addition, resting, and centrifugation was repeated three times. All supernatants were combined in the graduated cylinder, and the final volume was adjusted to 25 mL with 80% ethanol. This alcoholic extract was used for the quantification of reducing and total soluble sugars.
The quantification of reducing sugars was performed using the Somogyi-Nelson method (NELSON, 1944). The alcoholic extracts from the samples were mixed with Nelson’s reagent, and after boiling, absorbances were measured in a spectrophotometer at 540 nm. Reducing sugar concentrations were estimated using a standard glucose curve.
For the quantification of total soluble sugars, the phenol-sulfuric method was used (DUBOIS et al., 1956). After the reaction, readings were taken in a spectrophotometer at 490 nm (Shimadzu, UV-1601 model). The concentration of total soluble sugars was estimated based on a standard curve prepared with different sucrose concentrations.
The results obtained were subjected to analysis of variance. The means of the main plots and subplots were compared using Tukey’s test at a 5% probability level, while sub-subplots were analyzed through regression analysis. The regression model was selected based on its biological significance, the significance of the regression coefficients using the t-test at a probability level of up to 10%, and the coefficient of determination.
Results and discussion
The tubers of the Asterix, Challenger, Ludmila, and Markies cultivars, after harvest and curing, did not visually present an undesirable dark coloration when subjected to the frying process, as perceived by consumers (Figure 1).

After 180 days of tuber storage at 4°C and 8°C, an increase in dark coloration was observed in the fries after frying. However, visual differences were noted among the Asterix, Challenger, Ludmila, and Markies’s cultivars (Figure 2). The Markies cultivar, stored at 8°C, visually exhibited a lighter color (Figure 2).

Non-enzymatic browning or the Maillard reaction is one of the challenges when frying tubers (LOW et al., 1989). The Maillard reaction involves a series of steps that begin with a reaction between the carbonyl or acetone group of the reducing sugar and the amino group of amino acids. This reaction is influenced by temperature, and at a frying temperature of 180°C, a high reaction efficiency is achieved (RICHARDSON et al., 1990).
No significant differences were observed in the reducing sugar and total soluble sugar levels among the Asterix, Challenger, Ludmila, and Markies’s cultivars after harvest and the curing period (Tables 1 and 2). In all cultivars evaluated in this study, the reducing sugar levels after harvest and curing were below the recommended levels for French fries. For tubers to be accepted for French fry processing, reducing sugar levels should be below 0.12% of fresh weight for fries (STARK et al., 2020).

The sugar content is an important characteristic of tubers intended for French fry production, whether in chip or fry form, and is determined by the cultivar and various environmental factors during crop growth and development, such as temperature and post-harvest storage conditions (KUMAR et al., 2004). Reducing sugar levels were statistically influenced by cultivar and storage temperature at each evaluation period.
Storage at 4°C caused different changes among cultivars. The Asterix cultivar showed high reducing sugar levels after just 30 days of storage, similar to the findings of Bacarin et al. (2005). The Challenger cultivar had the lowest reducing sugar levels at 30 and 150 days of storage, while Markies had the lowest reducing sugar levels at 30, 60, 90, 120, and 150 days of storage.
No significant differences were found among the cultivars stored at 8°C in terms of reducing sugar levels at 30, 60, 90, 120, 150, and 180 days.
Storage temperatures of 4°C and 8°C influenced reducing sugar levels in the Asterix, Challenger, Ludmila, and Markies’s cultivars. Lower reducing sugar values were observed at 8°C compared to 4°C. Bacarin et al. (2005) also found that storage at 4°C resulted in higher reducing sugar levels. They concluded that at low temperatures, respiratory activity is reduced, potentially explaining the accumulation of sugars in tubers stored at low temperatures (BACARIN et al., 2005).
The Asterix cultivar had the lowest average reducing sugar content at 8°C after 30 days of storage. The Challenger and Ludmila cultivars had the lowest reducing sugar values at 8°C after 60, 90, 120, 150, and 180 days, while after 60 days of storage, the lowest values were observed in Asterix, Challenger, and Ludmila. At 90, 150, and 180 days of storage, all cultivars stored at 8°C had lower average reducing sugar levels than those stored at 4°C, while at 120 days, only the Markies cultivar had a lower average reducing sugar content at 8°C than at 4°C.
High reducing sugar levels in tubers are the primary cause of undesirable browning in processed potato products, limiting the production of high-quality French fries (SOWOKINOS, 2001). Depending on the storage duration, cultivar, and physiological maturity of the tubers, sugar levels vary due to chemical and/or enzymatic hydrolysis (BACARIN et al., 2005). Total soluble sugar levels were statistically influenced by cultivar and storage temperature at each evaluation period.
Storage at 4°C caused different changes among cultivars. The lowest average total soluble sugar levels were found in the Asterix cultivar at 30 and 120 days of storage, in Challenger at 30 and 180 days, in Ludmila at 120 and 180 days, and in Markies at 30, 60, 90, and 180 days of storage. At 8°C, an effect on total soluble sugar levels was observed only in the Markies cultivar at 150 days of storage, where it had a lower value compared to the other cultivars.
Regardless of the cultivar, total soluble sugar levels were higher in tubers stored at 4°C compared to 8°C at each evaluation period.
Analyzing the storage time for each cultivar (Figures 3 and 4), it was observed that reducing sugar and total soluble sugar levels changed over the storage period. Rivero et al. (2003) identified three factors that determine chemical changes in potato tubers during storage: the initial condition of the tubers, storage duration, and storage conditions. Reducing sugar levels in Asterix, Challenger, Ludmila, and Markies increased over storage time when stored at 4°C. The highest estimated reducing sugar values at 180 days of storage were: Asterix: 0.931% (Figure 3A), Challenger: 0.777% (Figure 3B), Ludmila: 0.767% (Figure 3C), and Markies: 0.738% (Figure 3D).
At 8°C, only the reducing sugar content of Ludmila was not statistically influenced by storage time (Figure 3). The Asterix, Ludmila, and Markies’s cultivars had the highest estimated reducing sugar values at 180 days of storage: Asterix: 0.208% (Figure 3A), Challenger: 0.233% (Figure 3B), and Markies: 0.091% (Figure 3D).
The generally accepted reducing sugar content for potatoes used in processing is below 0.12% of fresh weight for fries (STARK et al., 2020). Only the Markies cultivar stored at 8°C for 180 days had a reduced sugar content below 0.12%. Results from Freitas et al. (2012) show that chip browning and reducing sugar concentration increased during tuber storage, with the highest browning and sugar values occurring at 4°C and 8°C. This suggests that the best storage temperature depends on the cultivar, the physiological age of the tuber, and growing conditions.
The Asterix, Challenger, Ludmila, and Markies cultivars exhibited different behaviors over storage time regarding total soluble sugar levels (Figure 4). Asterix and Markies stored at 4°C had the highest estimated total soluble sugar values at 180 days of storage: Asterix: 1.209% (Figure 4A) and Markies: 0.812% (Figure 4D). The Challenger cultivar showed a quadratic trend, with a maximum soluble sugar content of 1.040% at 124 days of storage. The total soluble sugar content of Ludmila was not influenced by storage time, with an average value of 0.639% (Figure 4C).
At 8°C, only the Challenger and Markies cultivars were influenced by storage time (Figures 4B and 4D). The highest total soluble sugar content, 0.216%, was obtained at 180 days for Challenger (Figure 4B), while the highest value, 0.151%, was observed at 110 days for Markies (Figure 4D). The average total soluble sugar content for Asterix and Ludmila at 8°C was 0.239% and 0.230%, respectively (Figures 4A and 4C).

Reconditioning
At 150 days after storage at 4°C and 8°C, the tubers were subjected to reconditioning. The visual responses of the cultivars after the frying process are shown in figure 5. There were different color responses among the Asterix, Challenger, Ludmila, and Markies’s cultivars after reconditioning and subsequent frying (Figure 5). All cultivars stored at 4°C and then subjected to reconditioning exhibited an undesirable dark coloration for consumers (Figures 5A, 5C, 5E, and 5G). In contrast, the Ludmila and Markies cultivars stored at 8°C and then reconditioned visually presented a lighter coloration after frying, which is more accepted by consumers (Figures 5F and 5H).

After reconditioning, the levels of reducing sugars were statistically influenced by the cultivar and storage temperature at each evaluation period. Tubers subjected to reconditioning after being stored at 4°C exhibited different alterations among cultivars. The Asterix cultivar showed the lowest reducing sugar content at 60 days, Markies at 60, 90, and 120 days, and Challenger at 150 days. There were no statistical differences among cultivars stored at 8°C after reconditioning in terms of reducing sugar content at 60, 90, 120, and 150 days. Singh et al. (2008), it was found that, after storage at different temperatures (4 to 20 °C) and subsequent reconditioning, the levels of reducing sugars varied significantly among cultivars and thermal conditions.
Reconditioning, storage temperatures of 4°C and 8°C influenced the reducing sugar levels in the cultivars evaluated. The lowest levels were obtained at 8°C compared to those at 4°C. The Asterix cultivar had the lowest average reducing sugar content at 8°C at 90, 120, and 150 days. Challenger and Ludmila had the lowest reducing sugar levels at 8°C at 60, 90, 120, and 150 days, whereas Markies showed the lowest value only at 60 days.
The total soluble sugar levels after reconditioning were statistically influenced by the cultivar and storage temperature at each evaluation period. Storage at 4°C caused different alterations among cultivars. The lowest average total soluble sugar values were obtained for Asterix at 60 days and Markies at 60, 90, and 120 days. There was no effect of 8°C storage temperature after reconditioning on total soluble sugar content for the evaluated cultivars. Analyzing reconditioning after storage for each evaluated cultivar (Figures 6 and 7), it is possible to observe that reducing and total soluble sugar levels changed over the reconditioning period (Figures 6 and 7). The study by potato CV. Innovator revealed that, after storage at 6, 7, and 8°C followed by reconditioning at 15°C, both the total soluble sugar content and its specific components (reducing and non-reducing sugars) exhibited statistically significant variations throughout the evaluated periods, influenced by the cultivar examined (PEREIRA et al., 2021).
The reducing sugar levels for the Asterix and Ludmila cultivars increased over the reconditioning period after storage at 4°C. The highest estimated reducing sugar values at 150 days of reconditioning were: Asterix: 0.712% (Figure 6A) and Ludmila: 0.679% (Figure 6C). At 8°C storage, only the Ludmila cultivar was not statistically influenced by reducing sugar content by the reconditioning period (Figure 6). The Asterix and Markies cultivars had the highest estimated reducing sugar values at 150 days after reconditioning. The values were: Asterix: 0.174% (Figure 6A) and Markies: 0.091% (Figure 6D). Meanwhile, the Challenger cultivar had an estimated maximum value of 0.065% at 103 days after reconditioning (Figure 6B). Chapper et al. (2004), evaluating storage at 2°C for 10 days followed by reconditioning at 15°C for 10 or 20 days for the Eliza, Pérola, and Atlantic cultivars, found that reconditioning reduced sugar levels only in the Pérola and Atlantic cultivars.

Figure 6 – Reducing sugar content as a function of the reconditioning time after storage at 4°C and 8°C. (A) Asterix: (•) 4°C and (◦) 8°C; (B) Challenger: (•) 4°C and (◦) 8°C; (C) Ludmila: (•) 4°C and (◦) 8°C; (D) Markies: (•) 4°C and (◦) 8°C.
The generally accepted reducing sugar content for potatoes used in processing is below 0.12% of fresh weight for fries (STARK et al., 2020). This value was achieved by the Challenger, Ludmila, and Markies cultivars at 8°C at 103, 150, and 150 days after reconditioning, respectively. Reconditioning the Challenger, Ludmila, and Markies cultivars after 8°C storage resulted in a reduction in reducing sugars. Bacarin et al. (2005), evaluating the Asterix, Atlantic, Pérola, and C-1786-6-94 genotypes, observed that reconditioning from 4°C to 20°C reduced reducing sugar levels.
The Asterix, Challenger, Ludmila, and Markies cultivars exhibited different behaviors over the reconditioning period regarding total soluble sugar content (Figure 7). Only the Markies cultivar at 4°C was influenced by the reconditioning time, reaching an estimated maximum value of 0.125% for total soluble sugar content at 106 days after reconditioning (Figure 7D). During reconditioning after storage at 8°C, only the Challenger and Ludmila cultivars had their total soluble sugar levels influenced by reconditioning time (Figures 7B and 7C). The estimated maximum total soluble sugar value for Challenger was 0.140% at 89 days after reconditioning (Figure 7B), while Ludmila had the highest estimated value of 0.208% at 150 days of reconditioning (Figure 7C). The average total soluble sugar values for Asterix and Markies at 8°C were 0.248% and 0.123%, respectively (Figures 7A and 7D). Salomão et al. (2022) evaluated the total soluble sugar content in two potato cultivars (‘Ágata’ and ‘Atlantic’) during storage and reconditioning and concluded that there were isolated indications of significant influence from both the cultivar and the evaluated periods on the concentrations of total soluble sugars.

Figure 7 – Total soluble sugar content as a function of the reconditioning time after storage at 4°C and 8°C. (A) Asterix: (•) 4°C and (◦) 8°C; (B) Challenger: (•) 4°C and (◦) 8°C; (C) Ludmila: (•) 4°C and (◦) 8°C; (D) Markies: (•) 4°C and (◦) 8°C.
Conclusion
Thus, we can conclude that: Storage of the Asterix, Challenger, Ludmila, and Markies cultivars at 4°C increased reducing and total soluble sugar levels; Reconditioning after the storage period at 8°C contributed to reducing reducing and total soluble sugar levels; The Markies cultivar may be a good option for storing potato tubers at 8°C.
