glycoalkaloids → considered unsafe → S. macrocarpon
threshold: 5-10 times higher than the value considered to be safe in foods
“According to these results, the glycoalkaloid levels of S. macrocarpon fruits are 5-10 times higher than the value considered to be safe in foods and might not be considered suitable for human consumption.”
total glycoalkaloids (TGAs) → exceeds safe limits → potato cultivars FD8-3 and Cardinal
concentration_FD8-3: 2539.18 ± 89.77 mg/100 g DWconcentration_Cardinal: 506.16 ± 17.90 mg/kg
“All the potato cultivars contained lower concentration of TGA than the limits recommended as safe, except 2 cultivars, that is FD8-3 (2539.18 ± 89.77 mg/100 g of DW) and Cardinal (506.16 ± 17.90 mg/kg).”
total glycoalkaloids (TGAs) → exceeds safe limits → potato cultivar FD 8-3
concentration: 154.93 ± 7.75 mg/100 g DW
“The dietary intake assessment of potato cultivars revealed that Cardinal, FD 35-36, FD 8-3, and FD 3-9 contained higher amount of TGA in whole potato, although FD 8-3 only possessed higher content of TGA (154.93 ± 7.75) in its flesh portion rendering it unfit for human consumption.”
glycoalkaloids → remain below → 200 mg kg−1 fresh tubers
“In all tested cultivars, however, the GA concentration remained lower than the recommended food safety level (200 mg kg−1 fresh tubers)”
antimicrobial substance → becomes inactive → under neutral and alkaline condition (pH 7.0 to 9.0)
“but became inactive under neutral and alkaline condition (pH 7.0 to 9.0)”
glycoalkaloid content → is below → safe limit
location: flesh
“Contents in the flesh were below the safe limit for all varieties, but were generally above in the skin.”
glycoalkaloids → exceed → 200 mg kg^-1
variety: Magnum Bonumpercentage: 66%
“Sixty-six percent of the samples exceeded a temporary maximum residue limit of 200 mg kg^-1”
glycoalkaloids → have → controversial safe levels
“Possible safe levels are controversial; guidelines limiting glycoalkaloid content of potato cultivars are currently being debated.”
glycoalkaloids → accumulate in → potatoes
conditions: during growth,postharvest storage
“Potatoes are known to accumulate glycoalkaloids (GAs) during growth and postharvest storage.”
glycoalkaloids → considered safe → S. aethiopicum
threshold: about 14% of values considered as toxic
“According to these results, the glycoalkaloid levels of S. macrocarpon fruits are 5-10 times higher than the value considered to be safe in foods and might not be considered suitable for human consumption; however, the glycoalkaloid levels of S. aethiopicum were similar to those of S. melongena (about 14% of values considered as toxic) and could be considered as safe for consumption.”
