“…The upsurge in reducing sugar content and dry matter declination negatively affects the processing quality attributes of the tubers that hamper the formation of chips, French fries, and post-harvest traits [22,23]. The increased sucrose, reducing sugars under biotic and abiotic stresses, not only affects the cooking quality but also leads to the formation of acrylamide, which is non-desirable for consumption [24][25][26].…”

“…Potato comes under the category of high GI foods, and it is usually recommended to eat in food combinations with low GI foods [22,27]. Resistant starch (RS) is considered a good dietary fiber source in potato for improved gut microbiota, a balanced GI, and a strengthened digestive tract [26,28]. The RS is negatively correlated with GI since RS slows down digestion, resulting in low glucose absorption in the bloodstream.…”

Potato dry rot disease caused by multiple Fusarium species is a major global concern in potato production. In this investigation, the tubers of cultivars Kufri Jyoti and Kufri Frysona were artificially inoculated with an individual or combined inoculum of Fusarium sambucinum and Fusarium solani. Fusarium sambucinum caused a significantly higher lesion development (p < 0.01) than Fusarium solani, irrespective of cultivars. The combined inoculum of both the Fusarium species caused significantly higher rot development (p < 0.005) in inoculated tubers. Analyses of starch and amylose content revealed that individual or mixed infection of fungi caused a significant reduction (p < 0.005) in these parameters compared to healthy tubers. The increased starch digestibility due to fungal infection caused a higher glycemic index and glycemic load. The resistant starch also deteriorated in the infected potato tubers as compared to the control. Kufri Jyoti showed a higher starch and amylose content reduction in response to the treatments compared to Kufri Frysona. The correlation analysis demonstrated a negative correlation in lesion diameter and rot volume with starch and amylose content (p < −0.80). However, the glycemic index and resistant starch were positively correlated with lesion development. Altogether, these findings highlight the progressive deterioration of quality parameters, which will be a critical concern for processing industry stakeholders and consumers.
