In this study, the effect of different anti-browning agents on the enzymatic browning in the cloudy apple juice from Amasya cultivar was compared by considering colour changes. For this purpose, L-cysteine, kojic acid and 4-hexylresorcinol were used at different concentrations in the apple juice (0-4 mM). They were found as effective inhibitors. The combination of L-cysteine, kojic acid and 4-hexylresorcinol was also studied for the control of enzymatic browning. The results showed that 89.2% inhibition was obtained at the end of 24 h storage period with the combination of 3.96 mM L-cysteine, 2.78 mM kojic acid and 2.34 mM 4-hexylresorcinol in the cloudy apple juice. L-Cysteine was found to be the most significant anti-browning agent. The interaction of kojic acid and 4-hexylresorcinol was found to have a positive effect on the inhibition of enzymatic browning.

Effect of extrusion on the functional properties of carrot pulp added extrudates and in-vitro bioaccessibility of lutein and beta-carotene
Ortak, Melda; Şensoy, İlkay; Ögel, Zümrüt Begüm; Department of Food Engineering (2014)
In this study, effects of extrusion on the functional properties of carrot pulp added extrudates was investigated. Extrusion was performed at four different conditions. Two different temperature profile and two different screw speeds were investigated. Change in antioxidant activity, phenolic content, β-carotene and lutein content and their in-vitro bioaccessibilities after extrusion were investigated. Antioxidant activity and total phenolic content was determined by DPPH and Folin–Ciocalteu method, respect...
Inhibition of enzymatic browning in cloudy apple juice with selected antibrowning agents
Bayındırlı, Alev (2002-06-01)
Golden Delicious apple juice was subjected to enzymic browning in the presence of the selected antibrowning agents: ascorbic acid, isoascorbic acid, l-cysteine, sorbic acid, benzoic acid, cinnamic acid and β-cyclodextrin. The relative effectiveness of these antibrowning agents for inhibition of enzymic browning in apple juice was determined in terms of colour and enzyme activity measurements with respect to time for approximately one day storage period at . The most effective agents were determined as l-cys...
Effect of salt stress on antioxidant defense systems of sensitive and resistance cultivars of lentil(Lens culinaris M.)
Cicerali, Işın Nur; Yücel, Ayşe Meral; Department of Biotechnology (2004)
In this study, two lentil cultivars (Lens culinaris, Medik.) (ILL5582-salt tolerant and ILL590) were characterized and compared due to their NaCl susceptibility and antioxidant mechanism was examined under laboratory conditions. Physiological parameters such as wet-dry weight, root-shoot lengths, cell membrane stability, lipid peroxidation in terms of malondialdehyde (MDA), H2O2, proline contents were determined. The activities of antioxidant enzymes such as superoxide dismutase (SOD: EC 1.15.1.1), catalase...

Golden Delicious apple juice was subjected to enzymic browning in the presence of the selected antibrowning agents: ascorbic acid, isoascorbic acid, L-cysteine, sorbic acid, benzoic acid, cinnamic acid and beta-cyclodextrin. The relative effectiveness of these antibrowning agents for inhibition of enzymic browning in apple juice was determined in terms of colour and enzyme activity measurements with respect to time for approximately one day storage period at 25 +/- 1 degreesC. The most effective agents were...
Effect of Anaerobic Azo Dye Reduction on Continuous Sludge Digestion
Ozkan-Yucel, Umay Gokce; Gökçay, Celal Ferdi (Wiley, 2014-10-01)
Effect of continuous feeding of a reactive azo dye, reactive orange 107, and its hydrolyzed form (HRO107), on a conventional anaerobic digester was investigated in this study together with observation of change in microbial community. Laboratory-scale digesters were fed with waste activated sludge and azo dye for 575 days continuously. The influent concentrations of reactive azo dye were between 200 and 3200 mg/L. The digester performance was not adversely affected by azo dye and its reduction metabolites t...
