    One sided UV-C treatments maintain quality of fresh-cut green onions
    (Uludağ Üniversitesi, 2010) Kasım, Rezzan; Kasım, M. Ufuk
    Storage quality of fresh-cut green onions as affected by UV-C treatments, so in this research the effect of UV-C treatments on quality was investigated in fresh-cut green onions. Four different UV-C treatments were used for ultraviole radiation to onions, and non-treated samples as evaluated control group. After UV-C treatments onions were stored at 5o C and 85-90% RH for 15 days. Quality attributes of samples were evaluated periodically in terms of antioxidant activity, electroliyte leakage, color, weight loss, decay percentage and inner leaf extension. Electrolyte leakage of fresh-cut green onions was getting high with the higher doses of UV-C so, the lower doses can be used for controlled pathogen growth because of both lower electrolyte leakage and lower decay percentage at the day 10th. L* value of white stem tissues maintain best in UV-C5 treatment whereas green color of hollow green tissues was retained best in UV-C3 treatment. Onions in UV-C15 treatment were shown noticeable yellowing however inner leaf extension of onions was effectively controlled by the UV-C15 treatment. Antioxidant activity of fresh-cut green onion was enhanced higher doses of UV-C treatments, especially UV-C15.
