“…High total glycoalkaloid (TGA) levels are found in tissues with intensive metabolic processes -in fruit, leaves, stems, tubers, tuber eyes, jacket, sprouts and damaged tissues Dixon 1996, Pęksa et al 2002). Possibly, the main function of glycoalkaloids is to protect plants from bacterial and fungal diseases as well as from pests (Colorado potato beetle, wireworms) (Lachman et al 2001, Didier et al 2003, Miller et al 2003. Potato cultivars with glycoalkaloid levels not exceeding 200 mg/kg fresh weight of tubers (including jacket) are generally recognised as safe for human consumption; however, the concentration above 100 mg/kg fresh weight affects the taste of tubers (Friedman et al 1997, Karim et al 1997, Mazurczyk and Lis 2000, Jansky 2010).…”

The field experiment was carried out during [2004][2005][2006]. The aim of the study was to determine the influence of insecticides (Actara 25 WG -0.08 kg/ha, Regent 200 SC -0.1 L/ha, Calypso 480 SC -three rates: 0.05; 0.075; 0.1 L/ha), used for controlling Colorado potato beetle, on total glycoalkaloid (TGA) content in potato leaves and tubers of three cultivars (Mors, Wiking, Żagiel). The insecticides significantly increased (Calypso 480 SC) or decreased (Actara 80 WG, Regent 200 SC) the TGA content in potato leaves, and increased TGA in tubers as compared with tubers harvested from the control. Leaves and tubers of cultivar Mors had the highest TGA contents, whereas Żagiel leaves and Wiking tubers had the lowest levels.

“…Native/control starch had the lowest values. Fluctuation in glycemic index for different individuals is due to the intra- and interindividual variability of glycemic index [ 31 ], but that does not necessarily mean that there are real differences between the subjects [ 32 ]. Many factors could lead to variations in blood glucose response even within the same individual.…”

The current study is aimed at modifying the structural makeup of potato starch through the application of heat and moisture to better control the postprandial glycemic response. Heat-moisture treatment (HMT) was used to prepare potato starch using different moisture levels and temperatures. The samples were digested with pancreatin to determine the % of easily digestible, slowly digestible, and resistant starch. Subjects were given pudding made with HMT potato starch, and their postprandial glycemic response was tracked by measuring their blood glucose levels. In addition, incremental and total incremental areas under the curve (IAUC, TIAUC) were also assessed. The current findings of in vitro enzymatic digestibility of potato starch showed inconsistent results as measured at different time intervals. Adding moisture and heating the mixture to 30 and 70°C both increased the amount of rapidly digestible starch in all of the treatments from 20 to 40%. The maximum value of slowly digestible starch was 43.63% when the sample was heated to 30°C with a moisture content of 30%. The highest value (68.46%) for resistant starch was achieved at 20% moisture level and 30°C. After eating pudding, blood sugar spiked for the first 60 and 90 min before gradually dropping off over the next 240 min. As a whole, the highest IAUC and TIAUC values, as well as the glycemic index and load, were observed in potato starch heated to 70°C, which contained 40% moisture. Most parameters achieved their highest values when 40% moisture was added and the heat was applied at 70°C.
