Item Effects of controlled atmosphere storage and low-dose irradiation on potato tuber components affecting acrylamide and color formations upon frying(Springer, 2007-04) Gökmen, Vural; Serpen, Arda; Acar, Jale; Akbudak, Bülent; Eriş, Atilla; Turan, Z. Metin; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 13606221900; 6505789772; 6602612385The effects of normal and controlled atmosphere combinations on tuber components responsible for acrylamide formation were studied during prolonged storage at 9±1 °C using the tubers of "Agria" and "Russet Burbank." The effects of low-dose irradiation (50, 200 Gy) prior to normal atmosphere storage were also studied. There was only a limited increase in the concentrations of sugars during 6 month of storage under normal atmosphere conditions. Low-dose irradiation slightly decreased the rate of sweetening in the tubers. The potential of acrylamide formation remained almost the same; however, the loss of firmness became clearer during 6 month of storage under normal atmosphere conditions. Controlled atmosphere storage in which O2 was deficient to a sufficient respiration increased the concentrations of sugars, and thus, the potential of acrylamide formation in potatoes upon frying at 170 °C for 10 min. The sum of glucose and fructose concentrations showed a good correlation (r 2 ∼ 0.90) with the potential of acrylamide formation for both cultivars.
